B-Complex Vitamins - Domo Futu
Most people don’t think twice about B vitamins — until they’re deficient. Then suddenly you’re tired, foggy, irritable, maybe even tingling in your hands. B-complex is the multi-tool of the micro-nutrient world: essential for energy, nervous system health, detox, brain chemistry, and beyond.
But does supplementing with a B-complex actually help? Let’s sort the essentials from the excess with the Evidence-Based Truth Claim Scale (ETCS).
B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), and B7 (biotin) are all required for ATP production in mitochondria.
Supplementation may improve mood and focus — especially in high-stress individuals or those with genetic variants (e.g., MTHFR).
Studies show mixed results on whether reducing homocysteine always translates to fewer cardiovascular events — but mechanistically, the logic holds.
Is a B-complex supplement worth it? If you're under chronic stress, on common medications, burning mental fuel, or just not eating like a nutrition textbook — yes. It’s foundational. Invisible when it’s working, but very noticeable when it’s not.
