Key takeaways
- Two amino acids (L-Arginine and L-Citrulline) support nitric oxide and blood flow.
- Fenugreek, Tribulus, Zinc and Vitamin D3 support normal hormone function.
- Ginseng, Maca, Ashwagandha and Horny Goat Weed support energy, desire and stress balance.
The circulation pair: L-Arginine and L-Citrulline
L-Arginine is an amino acid your body uses to make nitric oxide, which relaxes blood vessel walls. L-Citrulline is turned into L-Arginine in the kidneys and tends to raise arginine levels more steadily, which is why the two are often paired. We compare them side by side in L-Arginine vs L-Citrulline.
The hormone-support group
Fenugreek is a seed extract studied for supporting healthy free testosterone and libido in men. Tribulus Terrestris has a long history in traditional medicine for vitality. Zinc is required for normal testosterone production, and Vitamin D3 plays a role in hormone health; many adults fall short on both. The NIH has helpful fact sheets on zinc and vitamin D.

The energy and desire group
Panax Ginseng is one of the most researched adaptogens and has been studied for energy and erectile function (NCCIH overview). Maca Root is a Peruvian root traditionally used for stamina and libido. Horny Goat Weed contains icariin and has been used for centuries in Traditional Chinese Medicine for male vitality.
The stress balancer: Ashwagandha
Ashwagandha helps the body cope with stress and may lower cortisol. Because chronic stress can dampen desire and hormone balance, it earns its place in the formula. Read more in Ashwagandha, stress and libido.
Why a blend instead of one ingredient?
Male performance depends on several systems at once: circulation, hormones, energy and mood. A blend lets each ingredient cover a different piece. See the full ingredient list and NIH research links on our homepage.
