What the Evidence Says
AI-generated · Qwen 3.6 · methodologyRiboflavin, niacin, and folate are B vitamins that support energy metabolism and cellular function, with strong evidence for their general physiological roles. The proprietary blend lacks specific transparency, contributing to limited overall evidence coverage. The formulation maintains a moderate safety profile.
