When we say you'd have a hard time finding a higher quality selenium supplement, we mean it. There are actually four types of selenium and the research shows selenomethionine is ideal for absorption, and reduced risk of toxicity. Thiosel is made with the highest quality organically-sourced, selenomethionine from selenium enriched yeast.
Thiosel has one pure ingredient inside a veggie capsule, which means no extra fillers. Our customers have enough food sensitivities, that's why our supplements are not blends with fillers.
