What it supports: Provides the building block for glutathione, the body's primary internal antioxidant and detoxification molecule. Supports liver health, immune function, and the body's natural ability to clear oxidative stress.[6]
Why we chose it: Nicotinamide is chosen over nicotinic acid for equivalent metabolic activity without the uncomfortable flushing response associated with high-dose nicotinic acid.
What it supports: Essential for NAD+ production, a coenzyme involved in hundreds of metabolic reactions, energy production, and DNA repair. Supports healthy skin, nervous system function, and cognitive performance.
Why we chose it: The stable calcium salt of pantothenic acid, widely used and well-absorbed.
What it supports: Supports production of Coenzyme A (CoA), central to energy metabolism and the synthesis of fatty acids, hormones, and neurotransmitters. Supports adrenal function and healthy stress response.
Why we chose it: Foundational cofactor for B-vitamin metabolism. Included because it helps activate other B vitamins and supports efficient folate metabolism.
What it supports: Supports cellular energy production, healthy skin, eyes, and the nervous system. Helps activate vitamin B6 and folate metabolism.[3]
Why we chose it: Most bioavailable selenium form, absorbed and retained significantly better than inorganic forms. The primary form of selenium found naturally in food.
What it supports: Required for glutathione peroxidase, the enzyme that uses glutathione to neutralise peroxides. Supports thyroid hormone activation, immune function, and cellular protection. Essential for the antioxidant system NAC builds.[7]
Why we chose it: Flow agent used during manufacturing for consistent tablet production and enteric coating stability. Chosen as an alternative to chemical-laden binders.
What it supports: At the trace amount used, silica supports manufacturing consistency and has no meaningful physiological impact in this context.
Why we chose it: A stable, well-absorbed form of thiamin. Water-soluble and not stored in the body, so regular intake is essential for consistent levels.
What it supports: Supports carbohydrate metabolism and the conversion of food into cellular energy. Essential for nervous system function, cognitive performance, and nerve signal transmission.

A multivitamin is only as good as what your body can use: so every methylation-critical nutrient is in its active form.
5-MTHF and dual active B12 (methyl + hydroxo) skip the conversion steps that MTHFR, MTR, and MTRR variants perform less efficiently.
P5P (B6) and riboflavin (B2) keep folate conversion and downstream methylation running at full efficiency.
NAC and selenomethionine feed glutathione, the antioxidant system that protects methylation from oxidative strain.
