The RBRN Vitality Formula

Meta-analyses show it reduces cortisol, supports strength gains during training, and improves sleep quality — with a modest increase in testosterone in men. Full-spectrum root extract.

Clinical trials show increased testosterone in both trained and aging men. Works by inhibiting the enzymes that convert testosterone to other hormones.

Centuries of traditional use backed by emerging research. Studies show improvements in free testosterone and sexual function, particularly in stressed men.

Even mild deficiency suppresses testosterone production. At 20mg, we provide enough to support optimal levels without excess.

One study found just one week of supplementation significantly increased free testosterone while decreasing estradiol in healthy men.

A direct NAD+ precursor. NAD+ declines roughly 50% between youth and middle age. Human studies show NMN supplementation successfully raises levels.

Promotes mitochondrial biogenesis — the creation of new mitochondria. More mitochondria, functioning more efficiently, means more energy capacity.

Enhances nitric oxide production, reduces blood pressure, and provides antioxidant protection. Also inhibits aromatase, complementing the testosterone stack.

Deficiency is remarkably common in men who work indoors. Influences over 1,000 genes and plays roles in immune function, mood, and hormone production.

Active P5P form. A cofactor for 100+ enzyme reactions including neurotransmitter synthesis and hormone metabolism. Essential biochemistry, not a headline — but the system needs it.

A patented blend of Panax notoginseng and Astragalus designed to enhance nutrient absorption — so the other eleven ingredients actually reach your cells.

Piperine from black pepper. Inhibits a liver process that eliminates supplement compounds before they reach effective levels. Small inclusion, outsized impact.
