Here’s the comment:

“Aside from the issue of synthetic versus whole is the issue of what is added to your supplement aside from the active ingredient. Many supplement makers are adding flowing agents into their capsules, such as magnesium stearate. Previous research has shown that magnesium stearate suppresses your natural killer cells, which are a key component of your immune system.

Magnesium stearate is much like a chalk filler that stimulates your gut to form a biofilm — a sort of sludge lining — that acts as an effective barrier to the absorption of not only that particular vitamin but ALL the nutrients you’d normally get from food sources as well!”


My reply to Diane~

Diane, I hope you are able to continue to improve your situation. And many people end up tossing out supps and vitamins because we read how 1 or more ingredients in those are defeating the purpose. Nothing ventured, nothing gained though, right?


I just tossed out about $180 worth of vitamins and minerals because they have rice flour, magnesium stearate, etc in them. Why on earth would they put rice flour in an encapsulated enzyme? I guess I’ll make my own fermented veggies to get my flora and a nice side-dish too.


Also, thanks for the tip. I bought some Krill Oil caps from Dr. Mercola today.
