Vitamin B-Komplex | Energize: can a DNA test help?

A DNA test can theoretically identify genetic variants affecting B vitamin metabolism (e.g., MTHFR, MTRR, FUT2). However, the evidence that this translates into meaningful energy improvements is weak. Most people meet their B vitamin needs through diet, and a genetic risk marker does not replace actual blood level measurements. Without a confirmed deficiency, supplementation rarely boosts energy. The evidence is mostly mechanistic; clinical trials show clear benefits only in those with a genuine deficiency. Therefore, a DNA test may serve as a conversation starter for better nutrition, but it should not be the sole basis for supplementation. Caveat: Not a medical diagnostic tool.
