B-Complex Vitamins: Why They Work Better Together

By The Gelagen Team · September 2026

The five B-vitamins in our formula are not independent actors. They form an interconnected metabolic network where each vitamin enables the others to function properly. Taking them together is a deliberate formulation choice.

The metabolic network

Biotin (B7): powers carboxylase enzymes for amino acid and fatty acid metabolism.
B12: works with folate in DNA synthesis and methylation reactions.
Folate: essential for cell division — useless without adequate B12 for the methionine synthase reaction.
B6: involved in over 100 enzyme reactions including amino acid conversions that feed keratin production.
Pantothenic Acid (B5): builds coenzyme A, the metabolic hub connecting fatty acid synthesis, energy production and hormone manufacturing.

Why single-ingredient supplements miss the point

Taking biotin alone without adequate B12 and folate is like having fuel without an engine. The B-vitamins are coenzymes — they enable the enzymes that do the actual work. Deficiency in any one creates a bottleneck for the entire system.

Our doses in context

B6 at 2mg (118% DV), B12 at 6mcg (250% DV), Folate at 442mcg DFE (111% DV), Pantothenic Acid at 5.2mg (104% DV), and Biotin at 5000mcg. Each is at or above 100% DV, ensuring no single B-vitamin bottleneck limits the system.
