Wish I'd read other negative reviews. Bought two different brands. Brand 1 worked great for months! After using them up, I switched to CodeAge. Within days my MCAS was out of control!!! Shame on CodeAge for not delivering proper potency. Saw another's comment (after the fact) that the CodeAge capsules were very pale compared to other brands. Now I know why. Now, to get any benefit, I must take 6 capsules with every meal rather than 2. I'll use them up and switch back to the other brand. Please note: CodeAge was wonderful about replacing damaged bottle with less-than-promised number of capsules. So, Customer Service is good. But the product? A waste of money. Plus, my life is literally at stake. I have gone from mastocystosis (merely cutaneous) to very serious MCAS.
