What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

This formula contains Maca and L-Arginine, which have limited to moderate evidence for supporting libido and blood flow. Niacin and calcium provide general nutritional support, while Yohimbe Bark Extract is used for arousal, though evidence for its efficacy is limited. The profile maintains a high safety score, indicating a low risk of adverse reactions for most users.
