I never can tell if any supplements I take actually has any effect on me, but I keep taking them. Everything I've read about these seem good and line up with the rest. Albeit, there's very little info to read about this particular item, aside from the possible benefits. All I can say for sure is, so far, after these for several days, no upset stomach issues. Dosing is only one capsule daily, so that's good. There's a faint smell to the capsules (standard size) and no aftertaste. Support small business.
