A B-vitamin within established cycling traditions.
Niacin is vitamin B3 — an essential water-soluble vitamin available in two main supplement forms: nicotinic acid (the flush form, traditional in protocol context) and nicotinamide / niacinamide (the non-flush form). The two forms behave differently in the body. The flush form transiently activates skin vasodilation; the non-flush form does not.
Niacin is not present in any current MYKO capsule formulation. It appears on label directions for Active Botanical products as an optional 25–50mg flush-form pairing within Stamets-style protocols. This monograph treats niacin as protocol-support education, not as a current MYKO product.
Optional pairing, not a required enhancer.
MYKO references niacin as optional protocol support inside Active Botanical product directions because it is a long-standing element of the Stamets cycling framework. The pairing is community-protocol-based and traditional within microdosing protocols, not a research-backed enhancement.
