What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

Vitamin B12, B6, and folic acid are essential nutrients that support neurological function and red blood cell formation. Strong research evidence supports their role in maintaining homocysteine levels and cognitive health. Stevia leaf extract serves as a non-nutritive sweetener with a well-documented safety profile.
