It is amazing how expensive supplements are these days despite little regulation by the FDA. I don't take any supplements unless I know exactly what they contain because many are not compatible with the prescription medications I take. You'd be surprised how many common supplements can be dangerous if taken with blood thinners.
On the other hand, some actually do work. I tried Nettle teas to reduce blood creatinine levels. I have some minor kidney issues that get progressively worse with age. The teas worked to reduce my creatinine levels but caused a spike in blood potassium! I'd rather have higher creatinine than risk a heart attack or other heart issues from high potassium.
