Natural Protein Powders have no artificial flavours or fillers just pure protein and pure qaulity.
This means no thickeners and gums, including xanthan gum. These are manufactured from soy or corn and can cause bloating and gas to some.
No Fillers. Fillers can sometimes be added to bulk up the protein and save money for the manufacturer. Some fillers include ingredients such as coconut flour or psyllium, which can cause bloating and reflux in people who have digestive issues.
No artificial flavours. Common artificial sweeteners used like sucralose, splenda, aspartamine or xylitol can cause negative side affects to some. Including bloating, and acid reflux.
