PPSU vs PP Bottle - Which is the best newborn feeding bottle?

PPSU vs PP Bottle - Which is the best newborn feeding bottle?

by Virendra Singh in Blogs

As a parent, you constantly face decisions that have potential consequences for your baby’s comfort, health, and well-being. Every choice matter, from the clothes to the food they eat and even the bottles they drink. Choosing between PP (Polypropylene) and PPSU (Polyphenylsulfone) newborn feeding bottles is more about finding the better option for your baby. Although both materials are popular, which is better for your baby and more practical for your style of living?

Here’s a breakdown so you can decide because only the best will do when it comes to your baby.

What Are PPSU Baby Bottles?

PPSU (Polyphenylsulfone) is a medical-grade plastic used in surgical tools and devices. Hence, it is sturdy and one of the safest materials for newborn feeding bottles . PPSU bottles pack safety, strength, and durability into a single bottle.

As per the studies, PPSU bottles have no harmful chemicals (substances related to the polymer structure). Also, it doesn’t release (or “migrate”) any toxic substances into the contents (like milk or water) under normal use conditions. (Source: Polyphenylsulfone (PPSU) for baby bottles: a comprehensive assessment on polymer-related non-intentionally added substances (NIAS))

PPSU is also 100% BPA, BPS, and phthalate-free, so you don’t have to worry, giving you peace of mind with every feed.

What Are PP Baby Bottles?

PP (Polypropylene) baby bottles are the most common and widely available. They are typically lightweight, budget-friendly, and BPA-free. You can quickly identify these bottles with the translucent milky caps on these bottles. You will find PP safe for daily life and accept high and low temperatures, but it has limits. It is preferable to use PP if you only plan to use it occasionally or in the short term.

PPSU vs PP Bottle: Why PPSU Stands Out?

PPSU and PP are still within the safety limits, but PPSU outperform in several areas. Here’s a closer look at why you might want to choose PPSU bottles for your baby:

Features PPSU (Polyphenylsulfone) Bottles PP (Polypropylene) Bottles
Durability Highly durable, resistant to impact and scratches Less durable, prone to wear and tear
Heat Resistance Can withstand high temperatures (up to 180°C) Lower heat resistance (up to 120°C)
Chemical Safety BPA-free, BPS-free, and resistant to chemicals BPA-free but may degrade faster
Transparency Amber-coloured, remains clear over time Milky white becomes cloudy with the use
Odor & Stain Resistance Resistant to odours and stains May absorb odours and stains over time
Lifespan Long-lasting, recommended replacement every 12 months Shorter lifespan, recommended replacement every 6 months
Ease of Cleaning Easy to clean and sterilise It can be harder to clean due to material ageing
Cost More expensive due to high durability More affordable and widely available

1. Superior Heat Resistance

PPSU bottles can withstand temp up to 180°C. Hence, you can sterilise them by boiling them in water or washing them in a dishwasher. PP bottles can only withstand temperatures up to 120°C, and repeated exposure to high heat can cause them to break down faster.

Thermal stability is key to hygiene. PPSU guarantees the bottle will be safe and intact through every sterilisation cycle.

2. Longer Lifespan

Bottles made of PPSU are durable. Whether you boil, microwave or wash them daily, they help keep clarity, shape and strength. In comparison, PP bottles (polypropylene) can become worn, discoloured, and warped in months (or even weeks).

For parents seeking long-term value, PPSU bottles are the wiser investment.

3. Crystal Clear Transparency

Unlike PP’s milky texture, PPSU bottles retain a clear, glass-like look, making checking milk quantity and cleanliness easier. You don’t have to guess whether it’s thoroughly washed or if there’s any residue hiding in a cloudy bottle.

A clear view means peace of mind with every feed.

4. Unmatched Durability

Dropping a PP bottle can cause cracks or damage. PPSU, however, offers excellent impact resistance. You can feel confident knowing your bottle won’t shatter or crack if accidentally dropped, making it ideal for active parenting and travel.

5. Odour and Stain Resistance

PP bottles can absorb odours from milk or cleaning agents over time, which is less than ideal. PPSU’s non-porous surface resists stains and smells, keeping your baby’s bottle fresh and clean for longer.

This feature is handy if you use formula or milk with vitamins or supplements, which tend to stain regular bottles.

6. Medical-Grade Safety

PPSU is approved for use in medical devices, so it’s safe. Unlike PP bottles, it doesn’t leach chemicals under heat or over time, which may degrade. So, if you’re looking for a feeding solution as safe as what hospitals trust, PPSU is your go-to.

7. Eco-Friendly and Cost-Efficient

Though PPSU bottles have a higher upfront cost than PP bottles, their longevity makes them more cost-efficient in the long run. You’ll use fewer bottles over time, reducing waste and saving money, a win for your wallet and the planet.

Newborn Feeding Bottles from MamaCare

Selecting the right feeding bottle for your newborn can mean a difference in comfort for both baby and mom. MamaCare’s PPSU feeding bottles are FDA-approved for food contact and are free of BPA, BPS, and phthalates. The bottle is paired with a silicon teat, which prevents backflow and provides a natural feeding posture. The anti-colic one-way flow valve reduces the chances of air intake for the baby.

Choosing the right baby bottle may seem small, but it plays a significant role in your daily routine and your baby’s comfort. PP bottles are a standard option, but when considering heat resistance, clarity, durability, and long-term value, PPSU bottles come out on top. MamaCare’s PPSU feeding bottles combine medical-grade safety, practical design, and durability to provide a hygienic, easy-to-use product.

10 Essential Nutrition Tips for Men & Women Entering Golden Years

Getting older brings a new set of changes in your body. The new body demands different dietary habits, and your tolerance for old food habits may decline. Many people find they aren’t as hungry, and alongside, their energy might go up and down, or they might get new health issues. It’s easy to forget that your diet might need to change too. Still, you can boost your energy and stay healthy by choosing the right foods. Eating better can make a massive difference in how you feel and what you can do daily. Here are ten crucial food tips that will help you eat well during the golden years of your life: 1. Prioritise Protein Power As we age, it’s common to lose some muscle mass. Sufficient protein intake prevents this. Protein helps to build and repair your body, including your muscles. Aim to include some protein in every meal. Boiled chicken, turkey, eggs, and fish (salmon, for example) are good choices. And if you are vegetarian, you can take milk, yoghurt, cheese, beans, lentils, tofu, and nuts. Tip: Eating protein, a little at a time over the day and not all at once is preferable. 2. Boost Bone Health with Calcium & Vitamin D Older people have a higher risk of getting weak bones (called osteoporosis). This is especially true for women after menopause. Your bones contain calcium, and Vitamin D helps your body absorb that calcium. Ensure you eat calcium-rich foods, such as dairy products, fortified plant-based milk, leafy green vegetables (kale, broccoli — though absorption does vary) and tinned fish with edible bones (such as sardines). Getting enough Vitamin D can be tricky. We get most of it from sunlight, but older skin also doesn’t make it. You might also spend less time outdoors. Look for foods with added Vitamin D. 3. Focus on Fibre for Digestive Wellness Sometimes, as you get older, your digestion slows down. This can make it hard to go to the toilet (constipation). Eating fibre helps keep everything moving smoothly. Fibre also helps control your blood sugar and can help you stay at a healthy weight. Eat more foods like oats, brown rice, and whole wheat bread. Fruits, vegetables, beans, peas, lentils, nuts, and seeds are also full of fibre. Try to eat about 25 to 30 grams of fibre each day. (Source: MedicineNet) Good sources include oats, pears, apples, and seeds like chia. Remember to drink more water when you eat more fibre. Water stops it from feeling uncomfortable in your tummy. 4. High Probiotic Diet Include high-probiotic foods in your diet. Probiotics enrich the good ecosystem in your gut, improve digestive functions and boost immunity. Foods that are rich in probiotics, such as yoghurt, kimchi, kefir, Sauerkraut, tempeh, pickles, etc., help you naturally support the microenvironment in your gut. However, with age, you may need to look elsewhere to support your digestive microsystems. You can use supplements with a high-probiotic diet, However, with age, you may need to look elsewhere to support your digestive microsystems. You can use supplements with a 5. Choose Healthy Fats for Heart and Brain Fats are not created equal. Unsaturated fats in oily fish (salmon, mackerel), avocados, nuts, seeds, and vegetable oils (like olive and rapeseed oil) are suitable for heart protection and brain function. Limit saturated fats in fatty meats, butter, lard, cream, cakes and biscuits. Avoid trans fats, which are often used in processed foods. Being anti-inflammatory, omega-3 fatty acids, especially from fatty fish, are suitable for general health. 6. Vitamins are Vital – Especially B12 Although all vitamins are critical, vitamin particularly stands out: vitamin B12. Its level increases or decreases with age since the production of stomach acid changes. Along with this, B12 is essential for nerve function and red blood cell formation. You can eat meat, fish, and eggs and take dairy products and fortified breakfast cereals, as these foods are rich in vitamins. If you follow a vegetarian or vegan diet, consider talking to your health specialist about checking your B12 levels because you may require supplementation. 7. Mind Your Minerals (Iron, Zinc, Magnesium) Iron helps with the transportation of oxygen in the blood and keeps anaemia-induced fatigue at bay. You must include red meat, beans, lentils, fortified cereals, and dark leafy greens, which are excellent sources of iron. Also, eat Vitamin C-rich foods like oranges to aid absorption. Zinc promotes your immune system and wound healing (sources: meat, shellfish, dairy, nuts). Magnesium is present in muscle and nerve functions that regulate blood sugar and blood pressure. Therefore, to maintain your blood level, increase your magnesium intake by eating green vegetables, nuts, seeds and whole grains. 8. Watch Portion Sizes, Not Just Content Your metabolism declines with age. You may require fewer calories than you used to during the younger age to maintain a healthy weight. But your nutrient needs usually stay the same or even go up. This is why nutrient density is so important (see next point). Be mindful of portion sizes to prevent accidental weight gain. Sometimes, using smaller plates can trick the eye and mind and make you feel satisfied with less food. You should listen to your body’s signals for hunger and fullness. Aim for 1.0–1.3 g/kg/day dietary protein combined with twice-weekly progressive resistance exercise (source: PMC). 9. Embrace Flavour to Combat Taste Changes Smell and taste changes are common with ageing; sometimes, these are related to medications or medical conditions. This can have the unfortunate effect of suppressing appetite or throwing its dependence on salt or sugar for flavour. Season your food naturally with herbs, spices, lemon juice, vinegar, garlic and onions rather than too much salt and sugar, as they can be bad for your blood pressure and general health. 10. Make Every Calorie Count with Nutrient Density Since you may not need as many calories, it’s even more important that your food is nutrient-dense. Nutrient-dense foods offer vitamins, minerals, fibre and other beneficial compounds relative to very few calories. Concentrate on whole, unprocessed foods: colourful fruits and vegetables, whole grains, lean proteins and healthy fats. Restrict foods high in ‘empty calories’, such as sweet sodas, candy bars, pastries and highly processed snacks. 11. Hydrate Diligently Throughout the Day As you get older, you might not feel thirsty, even without enough water. Being dehydrated can make you feel tired, dizzy, confused, or constipated. Make sure you drink often during the day. Drink even if you don’t feel thirsty. Low-fat milk, drinks made with sugar-free squash, tea, and coffee also count towards your fluids. Try to drink about 6 to 8 glasses (around 1.5 to 2 litres) every day. You might need more if it’s hot weather or if you are very active.

Nutrients Needed During Pregnancy & What to Eat After Giving Birth

Nutrients Needed During Pregnancy & What to Eat After Giving Birth

We all take proper care of nutrients needed during pregnancy, but what about post-pregnancy? After giving birth, your body demands more than just rest. Repairing and blood loss recuperation, emotional fatigue, hormonal changes, pain, and recovery require a good diet full of essential nutrition. Nutrition shifts can make the transition smoother, improve healing, and uplift one’s mood. To help you, we have prepared a complete diet plan for postpartum. Here are a few essential foods to eat after delivery and the reasons behind each food recommendation. Here are the seven most critical nutrients you need during and after pregnancy, to continue supporting your baby’s growth: 1. Protein-Packed Meals Recovery demands high amounts of protein due to tissue repair. Healing perineal tears or C-section incisions, retaining muscle mass and feeling satiety are critical. This is useful while managing energy levels and knowing how to get through the time available between feeds or naps. Furthermore, protein is a crucial component of breast milk. Best sources of protein: chicken, turkey, fish (especially oily varieties like salmon), lean beef or lamb, eggs, lentils, beans, chickpeas, tofu, and Greek yoghurt. 2. Complex Carbohydrates Do not avoid carbohydrates. Instead, avoid simple ones. Most complex carbohydrates are beneficial in fighting off mothers' constipation after giving birth. Consider whole-meal bread, oats (porridge is remarkably warm, soothing, and nutritious), brown rice, quinoa, wholewheat pasta, sweet potatoes, and starchy vegetables. These foods provide effective energy, aid in maintaining abdominal health, and are vital for the sustenance of B vitamins that help in metabolism, energy levels, and even mood. 3. Healthy Fats Healthy fats such as Omega-3 fatty acids DHA are key. If you’re breastfeeding, these fats are essential for your baby’s brain development. Omega-3 also supports brain function and mood regulation, helps quell inflammation throughout your body as it heals and is needed for absorbing fat-soluble vitamins. These beneficial fats are widely available from avocados, nuts (walnuts and almonds are among the best), seeds (chia seed, flaxseed, and pumpkin seed are a great choice), olive oil and oily fish (salmon, mackerel and sardines 1-2 portions weekly if you are mercury aware). Including these fats supports your baby’s neurological development through your milk and can, quite literally, help stabilise your mood and nutrient absorption. It is also a concentrated energy source. Research suggests adequate omega-3 intake may also help reduce the risk of postpartum depression. (Source: Omega-3 fatty acids and mental health) 4. Iron-Rich Foods Battling postpartum fatigue usually starts with iron. Blood loss during delivery is normal and can quickly drain your iron reserves, sometimes causing anaemia, which directly leads to symptoms of tiredness because iron is vital for producing haemoglobin to transport oxygen around your body. Increase your iron by eating lean red meat, poultry, fish, lentils, beans, fortified breakfast cereals, spinach, and dried apricots. A key recommendation is to combine these iron-rich foods with sources of Vitamin C (peppers, oranges, berries or broccoli!) within the same meal since Vitamin C dramatically increases iron absorption. Restoring iron in your body helps support energy, fight fatigue, and promote overall vitality. (Source: PubMed) 5. Calcium & Vitamin D If breastfeeding, calcium is also crucial for your little one's developing bones and teeth, so protecting your bone health is essential! Vitamin D helps absorb calcium, and it supports immune function, too. Some of the best sources of calcium include dairy products (milk, cheese, yoghurt), fortified plant-based milk, tinned fish with edible bones (sardines with the bones), leafy greens, and calcium-set tofu. For Vitamin D, oily fish and fortified foods play a part in providing safe exposure to sunlight. Everyone should take a Vitamin D supplement, particularly in the autumn and winter months, even postpartum mothers. Ensuring adequate intake protects your bone density, provides essential building blocks for your baby’s bones via milk, and supports immune health. 6. Fruits & Vegetables Try to eat lots of colourful fruits and vegetables every day. They give you essential vitamins, minerals, antioxidants, and fibre your body needs. Antioxidants help your body cope with the stress of healing and not getting enough sleep. Vitamins help with many body functions, like keeping your immune system strong. Fibre is essential to help your digestion stay regular. Don’t just stick to the same few foods. Add berries, oranges, peppers, carrots, broccoli, and leafy greens (like spinach or kale) to your meals and snacks. Eating a good mix helps you get a broader range of nutrients. This is great for your immune system and helps keep you regular. It gives you tiny nutrients that are key for your overall health and even help you stay hydrated. 7. Drink Plenty of Fluids (Especially Water) Drinking enough water is crucial after you've had your baby. This is especially true if you're breastfeeding, as breast milk is mainly made of water. Even being slightly dehydrated can make you feel much more tired. It can also lead to constipation and affect how much milk you produce. Make water your main drink all day long. A simple trick is to keep a water bottle right next to where you usually feed your baby or where you rest. This makes it easy to remember to take sips. Milk and herbal teas are safe for pregnancy and breastfeeding and count towards your fluids. Consuming water-based pregnancy and breastfeeding supplements also adds to your water consumption need All The Nutrients You Need During & After Pregnancy Eating well every day can be hard when you have a new baby. MamaCare’s Mother’s Nutrition packs all the nutrients you need as a new mother in easy-to-prepare and consume formula.

7 Superb Tips for Breastfeeding & Mom's Diet

7 Superb Tips for Breastfeeding & Mom's Diet

Breastfeeding strengthens the bond between a mother and child. Your baby gets nutrition and energy from what you eat. Breastfeeding and mom's diet are interconnected. Breastfeeding moms often face nutritional challenges like vitamin deficiencies (folic acid, B12, A, D), minerals (calcium, iron, iodine), and omega-3 fatty acids. Such deficiencies can potentially impact both your and your baby's health. Thus, a breastfeeding mom's diet should address these deficiencies and include adequate and diverse sources of nutrients. Understanding the Best Diet for Breastfeeding Moms You need a nurturing diet that fulfils your and the baby's needs during pregnancy. However, after the baby's birth, the mom's nutritional needs only continue as the baby will depend on you for a little longer. Thus, taking care of your diet during breastfeeding will ensure growth for the baby and good health for you. Dietary supplements can easily add all the nutrients you need while continuing your regular food choices. However, diet improvement also adds to your health goals and energy levels. Do You Need More Calories? Yes, you probably need to eat a bit more food each day. Aim to consume 330 to 400 more calories than usual daily. This will give you the necessary resources to produce milk. You can eat healthy snacks like whole-grain bread with peanut butter, banana, peanut butter, and yoghurt. How Much Water Do You Need During Breastfeeding? Breast milk primarily consists of water. Therefore, it is essential to drink enough water daily. You should drink at least a minimum of 8 to 12 glasses of water every day. According to research, a lactating woman should drink at least 3 litres of fluids daily. (Source: European Food Safety Authority, 2010) Best Diet Food for Breastfeeding Moms 1. Vitamin & Mineral-Rich Foods Add colourful food to your diet. Different coloured fruits and vegetables have various vitamins and minerals that are good for you and your baby. Some great choices are: Green Leafy Vegetables: Spinach and kale contain vitamins A, C, E, and K and calcium folate. Orange Coloured Fruit and Vegetables: Carrots and sweet potatoes are rich in vitamin A, which is necessary for proper eyesight and strengthens immunity. Blueberries and Strawberries: They contain antioxidants that guard your cells. 2. High-Protein Diet Protein contains essential nutrients that help build tissues, hormones, and enzymes, ensuring a healthy milk supply. You need to consume a lot of it to supply your milk and recover after delivery. A study shows breastfeeding mothers need 84 to 120 grams of protein daily. Or at least 1.5 times their body weight in grams. (Source: NIH NLM PMC) Some good sources of protein are: Poultry Cuts: chicken breast, turkey cuts, lean pieces of beef. Seafood: Salmon, tuna, and cod (just avoid ones with a high mercury content). Vegetarian Sources: beans and lentils are perfect options. Dairy Products: Eggs benefit everyone, offering great nutrition and versatility in meals. 3. Omega-3 Fatty Acids Omega-3s (especially DHA) are essential for your baby's brain development. You can use high-quality omega-3 supplements to make your food more nutritious. The best sources include: Fatty fish, such as salmon, mackerel, and sardines Chia seeds and flaxseeds Walnuts and almonds 4. Iron Intake Feeling tired while caring for a newborn is entirely normal, but low iron levels can worsen it. Iron-rich foods and vitamin C sources like citrus fruits and bell peppers help maximise absorption and benefits. Good sources of iron include: Red meat (beef and lamb) Dark leafy greens like spinach and kale Lentils and chickpeas Fortified cereals One faster way to recover from iron deficiency is through iron supplement tablets. MamaCare's Premium Women's Iron tablets contain iron, folic acid, vitamin B2, and vitamin C. The unique formula makes the tablets easy to digest and offers better iron absorption. Thus, it helps you recover faster and maintain energy levels during pregnancy or breastfeeding. 5. Boost Calcium for Bone Strength Calcium helps maintain strong bones and prevents osteoporosis. An individual's daily calcium intake should ideally be around 1,000 mg, which helps sustain bone density and ensures that essential nutrients are given to the baby. Make sure you use plenty of: Dairy products (milk, cheese, yoghurt) Almonds Green leafy vegetables Sesame seeds 6. Include Fibre-Rich Foods for Digestion Constipation is a common issue many women face during the breastfeeding phase. Therefore, keeping your immune and digestive systems functioning smoothly becomes crucial. Take a diet rich in fibre, including essential vitamins and minerals. Increase your fibre intake with: Whole grains (brown rice, oats, whole wheat bread) Fresh fruits and vegetables Nuts and seeds 7. Incorporate Superfoods Superfoods can enhance your milk supply and provide essential nutrients. Some top picks include: Oats – great for milk production Fenugreek – helps boost lactation Turmeric – known for its anti-inflammatory benefits Berries – rich in antioxidants for immunity What to avoid while breastfeeding? Some foods and drinks require more caution when breastfeeding. The following are a few: Alcohol: There is no "safe" level of alcohol consumption for a child exposed to breast milk. Caffeine: Avoid consuming more than two to three cups of coffee and other caffeinated beverages daily. Caffeine can contribute to a fussy baby and poor sleeping habits. Fish: Most fish can serve as a good source of protein and Omega 3 oils. However, many contain some level of mercury. Exceedingly high levels of mercury can potentially damage the brain and nerves of the baby. For the baby's safety, fish with extremely high amounts of mercury, such as swordfish and king mackerel, should be avoided. Supplements for Breastfeeding Mom's Diet Healthy foods are the most significant aid for breastfeeding. Everything you consume, whether high in protein, omega 3, or sufficient water, works towards the baby's development. Following a carefully crafted diet plan may not always be easy or possible, so that you can use dietary supplements. MamaCare's Mother's Nutrition powder is a dietary supplement which offers all the nutrients you need during and post-pregnancy to support baby's growth and your strength. Mother's Nutrition powder contains 30 plus nutrients, including protein, iron, calcium, multiple vitamins and folic acid. Folic acid during pregnancy reduces the risk of foetal neural tube defects and helps the baby's brain growth. It also helps in healthy blood cell formation and keeps moms healthy. It's a simple way to ensure you and your baby get everything to stay strong. We also recommend you consult with doctors before taking any supplement.
