What the Evidence Says

AI-generated · Qwen 3.6 · methodology

This formula combines essential minerals and vitamins with botanical extracts like Tongkat Ali and Fadogia Agrestis, which have limited evidence for supporting hormonal balance. While Magnesium and Vitamin D3 have strong research backing for general health, the evidence for the primary botanical ingredients is currently modest. The profile maintains a high safety rating.
