ESSENTIAL ONE is the world's most advanced single capsule multivitamin. It is a uniquely pure alternative to all the problems and additives of multivitamin tablets and gummies. Our small, easy-to-swallow capsules are gentle to even the most sensitive stomachs. We ensure that all key nutrients are provided in their proper forms and at their most beneficial levels. Essential One provides all the convenience and affordability you seek in a multivitamin without the stomach upset, additives and other problems of large, hard-to-swallow and difficult-to-digest multivitamin tablets or their even more ridiculous, calorie-laden, candy gummy cousins.

Essential One provides high potencies of Vitamin D3 (3,000 IU), Methyl B12 (100 mcg), along with a complete B-Complex, including 5-Methyl Folate (not ordinary Folic Acid) and 40 times more Biotin (for beauty) than the leading brands. We provide all three critical and costly carotenoids; Lutein, Lycopene and Zeaxanthin; along with a dozen other essential nutrients, including Mother Nature's most important nutrient for energy production and cellular protection Coenzyme Q10. We also add Vitamin K2 MK-7, recognized as essential for bone and heart health through its role in regulating calcium metabolism.

Contains no additives or common allergens of any kind
