So what’s wrong with powdered glycerol? There is nothing wrong with glycerol itself, but to make a powder, it’s combined with an ingredient called silica. Fundamentally this is where companies go wrong because this approach severely limits the amount of glycerol you can fit into a product serving. Some silica is ok, too much causes chalkiness and potential GI issues. To get the true hyperhydration effects pure glycerol is clinically proven to create, you need over 10x the amount found in most powdered glycerol products. This is based on REAL research and pretty much all the brands using powdered glycerol ignore this except for Evogen Nutrition.
