Natural supplements are just not regulated prior to manufacturing in the same way synthetic man-made chemical drugs are by the FDA. Pharmaceutical companies are held to strict standards for product clinical research before manufacturing and to strict purity standards thereafter. But, supplement manufacturers rarely invest in clinically testing their products, and product purity can be questionable. Supplements found on store shelves have been recalled for potential or proven harmful effects.
While many manufacturers may sell a supplement labeled with the same ingredients, there are really only a few brands that we recommend at Peak Health Group. These are the ones we healthcare professionals personally use, recommend for our families and carry in our offices. The companies that manufacture these brands are well established, well known, and respected in the industry. Their supplements are pharmaceutical grade manufactured in certified facilities with third party batch testing.
