## Description

Dr Clark Catalog

Review: Relaxation, Heart health, Brain, Gut, etc - Extremely important for the body, and as Ill mention below I believe in supplementing with good quality vitamins & herbs. Per my other reviews: given their history and what the company was founded upon, I found this brand to be a much safer and healthier option for vitamins / herbs. The VeriGMP stamp in addition to not using these toxic fillers (like 99% of other companies do) is why I swapped over to this brand. From my understanding these are also tested for contaminants. I encourage everyone to do their research beforehand. Majority of other vitamin companies are not to be trusted. The proof is the various fillers (many) which can be found on the back of the bottle. Also the other contaminants and metals that are most likely in there. I have been using this brand (ordering from both their site and desertcart) and haven’t looked back. Prices are good but more importantly the quality can be trusted.
Review: Many forms of magnesium out there - I have been happy with the magnesium oxide from Dr. Clark. I looked into magnesium as a sleep aid and feel this form of magnesium works well for me. To be honest, I haven't tried other forms to know the difference. It seems there's lots of opinions on what form of magnesium is better for what. Then there's lots of opinions on the side affects that each for may or may not have. This is all expected as this is a nutritional supplement and not a FDA approved drug that has gone through clinical trials. I have not experienced any noticeable side effects from Dr. Clark's magnesium oxide. I picked this brand of magnesium because it does not contain junk fillers and they are audited by VeriGMP for quality control.

- CLEAN & PURE CAPSULES We encapsulate our products only in the purest possible capsules. We don't use "HPMC" capsules (called "Veggie Caps") since those contain too many potentially hazardous chemicals. This product is made with pure, high quality, gelatin capsules made from hide (BSE Free). EXCIPIENT FREE - We don’t use magnesium stearate, artificial colorings, coatings, binders, junk fillers, or release agents in any of our products. Not now - Not ever
