What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

Calcium and magnesium are well-supported minerals that contribute to bone health and neuromuscular function. Butyric acid is a short-chain fatty acid associated with gut health, though evidence for its oral supplementation is more limited. Together, these ingredients support basic physiological functions with a high safety profile.
