What the Evidence Says

✨ AI-generated · Qwen 3.6 · grounded in 1 source · methodology

Magnesium and niacin support cellular energy production and neurological function, with magnesium L-threonate showing moderate evidence for crossing the blood-brain barrier. Research on these ingredients is generally well-established, though the specific combination in this formulation has limited clinical data. The profile maintains a fair safety rating for most adult users.
