Pros
- +Flexible dosing: powder lets you take 250 mg, 500 mg, or 2,000 mg without switching products — impossible with pre-dosed tablets

Cons
- -Distinctly sour taste — some reviewers need to mix with juice or honey to make it drinkable; one 3-star reviewer gave up on powder entirely

- -No independently verified third-party testing confirmed by product specs
Best For
Watch Out
