A Comment About Supplement Quality
There are many supplement choices, almost to an overwhelming degree. One way you can quickly narrow down what is worth spending your hard earned money on is looking at quality control. Unfortunately, dietary supplement quality control continues to be a problem in the US. Just look at reports done by places like Consumer Labs. At the least, supplements should have third-party testing done to make sure the label is accurate to what is in the bottle. This also helps ensure there is not contamination, such as heavy metals, in the product. Look for GMP, USP, NSF symbols, or if they are not on the bottle, contact the manufacturer to find out if third party quality control testing is done.
