Metabolic MaintenanceThe Big One without iron

The supplement contains folic acid in the form of calcium-L-methylfolate, an active and stable form that, unlike synthetic folic acid, does not need to be converted first. This form most closely resembles the natural folates in foods such as leafy greens.

This multivitamin contains both vitamin K1 (phylloquinone) and vitamin K2 (menaquinone-7, MK-7). Vitamin K1 is mainly found in green vegetables, while K2 comes from fermented foods like natto. The combination provides variation in absorption and availability.

The supplement contains a mix of mixed tocopherols, including d-alpha-tocopherol. This form is fat-soluble and naturally occurs in vegetable oils such as soybean oil, from which this variant is derived.

Many vitamins and minerals, such as A, D, E and K, are fat-soluble. Taking the supplement with a meal—ideally with some fat—promotes the absorption of these nutrients.

The form used is zinc citrate, a highly absorbable and widely used compound. Zinc naturally occurs in meat, fish, grains, and legumes, and is often added to multivitamins as an essential trace element.

Minerals are nutrients the body needs in relatively larger amounts, such as calcium and magnesium. Trace elements (or trace minerals) like zinc, selenium, and copper are, like minerals, essential, but are only needed in very small amounts.
