Not sure if this is a pro or con review...
November 1, 2010
This may be an unusual reaction but those few who need to know really need to know. Even though the outer capsule is not gelatin, it gave me an immediate MSG headache. I continued using the product by removing it from the capsule, and after four days' use, I had the headache that won't quit, that only resolved after I stopped using Sacro B. I can only guess that it's the magnesium citrate, which might not be tolerated by those with MSG sensitivity.
Pros:If you can tolerate the ingredients and this yeast it what you need. Also, this source has the best price.
Cons:Taking only eight and then having to stop due to a reaction.
