Dr. Tennant’s® Organic Sulfur uses 99.9% pure organic sulfur OptiMSM® Methylsulfonylmethane, which is non-GMO and has no fillers or anti-caking additives.

OptiMSM® is manufactured using a state-of-the-art, multi-stage distillation process ensuring optimal purity, quality, and consistency that is superior to any MSM product on the market.

Chemical engineers and other experts recognize the multi-stage distillation process used to purify OptiMSM® as the superior method. The end product is biomimetic, which means the same as that found in nature. 

In contrast to OptiMSM®, most other commercially available MSM products use crystallization to isolate the MSM molecule. As this crystallized material cools, occlusions can develop that trap contaminants within the MSM and lead to material that may contain heavy metals, residual water, and other impurities.

Additionally, other products use single or 2-stage distillation to purify MSM. These processes can’t match the multi-stage distillation purification processes used to make Opti-MSM®.

Suggested Use

Dissolve 1 teaspoon per 100lbs of body weight in 4 ounces of filtered hot water, twice daily or as recommended by your healthcare practitioner. 

Best if taken 30 minutes before or 2 hours after food.

Organic Sulfur Review

The product is fine. Easy to take. The taste is hard to describe, basically no taste but a sensation of coldness. Very odd. As far as it's effect, I haven't noticed anything yet but it seemed like a reasonable thing to try. I'll continue and see if any benefit is observed.
