10 Ingredients I Don’t Want In My Protein Powder

The key nutrient for fat loss and body shaping is protein as it’s essential to regulate the appetite, support lean muscle, boost metabolism and encourage significant weight loss –  but not all protein is created equal. Protein is essential because your body required adequate amino acids for the construction of enzymes that are integral to the detoxification pathways. A quality protein drink made from whole food ingredients can benefit your health in a number of ways. Protein powders can balance hormones, assist in weight loss, support detoxification and digestion, boost your immune system, and even support pregnancy.

Protein is also the key nutrient that helps you get ageless glowing skin and lean toned muscles. I’ve been in the fitness and health industry since my early 20s and have tasted many kinds of protein on the market. Some made me gain weight, some constipated me for days, and some made me feel bloated. This was the main reason I decided to design my own.




It’s important you choose the right protein powder that suits your needs and that supports your health in every way. It’s important they are un-denatured and free from chemicals and additives.


Here’s what you DON’T want in a protein powder:

1. Casein + WPC
These are also known as whey protein concentrate and caseinate. WPC’s and casein protein sources are high in lactose and poorly absorbed, which can often cause bloating, flatulence, and gastrointestinal distress in some people. It’s quite ironic that these powders actually started off as a weight gainer in medical institutions!


2. Gluten
Food sensitivities to gluten can elevate inflammation in some people and cause a range of health problems including hormonal imbalances, skin conditions, fatigue, mood swings, and headaches.


3. Dextrins/Maltodextrin
These ingredients can raise glycemic load, which may contribute to fat storage. Most are processed with GMO corn and they can also cause gastrointestinal distress in some people. They are mostly added to protein powders as fillers to bulk it out or make the protein mix easier.

4. Artificial sweeteners
Common artificial sweeteners used are sucralose, splenda (955), aspartamine, equal, NutraSweet (951), or saccharin (954). Several negative side effects can come from ingesting these ingredients, including headaches, migraines, gastric distress such as bloating, acid reflux and weight gain.


5. Skim milk powders/milk solids
Skim milk powders and milk solids are often used as a cheap bulking agent in less quality powders. They are high in lactose sugars, which can cause bloating, gastrointestinal distress, constipation, and loose stools.


6. Soy protein
Some soy proteins come from genetically-modified sources with high pesticide use. They contain chemical compounds which may cause hormonal disturbances in some people.

7. Vegetable oils and fats
These ingredients are often added to many weight loss and protein powders to increase richness and make them taste creamy. However, these fats are often derived from hydrogenated sources that contain trans fats, which are thought to be more harmful than saturated fats. Trans fats raise levels of bad cholesterol and lower levels of good cholesterol.


8. Thickeners and gums
Thickeners and gums, including xanthin gum, are manufactured from soy or corn and can cause bloating, constipation and gas. They are little like glue in my digestive system.


9. Fillers
Fillers are often added to bulk up the protein and save money for the manufacturer. Some fillers include ingredients such as coconut flour,  psyllium, sugar, which can cause gastric distress such as bloating, constipation and reflux in people who are susceptible to digestive issues.

10. Added fibres
Added fibres in protein powders are often included as a filler or weight management tool. For me personally, it causes gastric distress and bloating  as I have a particularly sensitive digestive system. The cleaner your protein powder, the better and the best fibres are obtained from plant based leafy greens, vegetables and fruits.

    Hi Teresa,
    Would you mind suggesting which one of your protein powders would be suitable for me.
    I’m on a gluten free diet as I react to the fructose in wheat. I also have to avoid any fruit or vegetables that are high in fructose. I keep away from lactose where possible, a bit of cheese or yogurt every now and then but if I have too much I get bloated. Don’t even start me on alcohol and how that sets off a bloated tummy. I’m also not a huge fan of red meat but I eat fish and chicken.
    I’d like to incorporate one of your protein powders in daily smoothies. Not sure how the pea protein works with the fructose load.
    I look forward to hearing from you.

    • Hi Tara our WPI is lactose free – the only one in Australia (carb and sugar free). I would definitely try this one first – you’ll love it. That being said our Organic Pea is completely dairy free and it’s also an isolate, so it’s free from carbs and FODMAPS that cause digestive issues. They are both awesome products which will be suited to you. We have 100 % money back guarantee on all our products, which not many other companies have. If you’re in Sydney I also suggest you pop into our Surry Hills Headquarters for a tasting session. Hope this helps. T:) x

    Hi Theresa,

    I’ve been on your pure oea protein now for a few weeks, I’m finding that I’m not getting the fullness and energy that I thought I would, do you suggest I change to the wpi instead?
    I am on a gluten free, lactose free diet at the moment.
    Thanks so much!

    Hello Teresa,

    Thanks for sharing this useful information here. I really found this post very interesting. Sometimes we make mistakes while choosing protein powders. But with these tips, one can find the right protein powder easily.

    Hi Teresa,

    I am trying to increase the protein in my diet but I am intolerant to dairy (even lactose free), legumes, eggs and white fish. Are there any particular protein powders you would recommend, I believe a brown rice protein might be best but I am unsure where to go after that.
