Black Ginger Extract (Kaempferia parviflora) (rhizome)
Ashwagandha Extract (Withania somnifera) (root) (KSM-66®)
Vitamin D3 (as cholecalciferol)
Vitamin K2 (as menaquinone-7)
Unlike stimulant-heavy energy products or generic performance blends, Nerlo Black Ginger is built around one clinically
studied Thai root traditionally associated with stamina and vitality. Human research has examined black ginger for body
composition, energy expenditure, endurance, physical performance, stress resilience, and healthy male vascular
function. It is designed for daily use without caffeine and without altering hormones.
Nerlo Black Ginger is designed for men and women who feel more tired, less capable, or less responsive to the same
routines that used to work. It is especially relevant for adults looking to support steady energy, stamina, strength, healthy
circulation, body composition, and everyday physical performance.
For best results, take the recommended serving daily with food and water. Black ginger is positioned as a consistent
daily supplement, not a quick-hit pre-workout. Clinical research commonly evaluates outcomes over several weeks of
regular use.

Black Ginger
Human trials, mostly Japanese and mostly in older or overweight adults, have looked at daily doses around 100–150mg for effects on energy expenditure, body fat, and exercise performance, with the polymethoxyflavones thought to work partly through PDE5 inhibition and brown fat activation.
Ashwagandha
The best-supported ingredient in your stack: multiple randomized controlled trials at 600mg daily show reductions in perceived stress and serum cortisol over 8 weeks, with secondary findings on sleep quality and, in a few trials, strength and testosterone in men. KSM-66 specifically is the extract most of that research used, so your dose and form match the literature.
Vitamin D3 + K2
D3 is well established for calcium absorption, bone health, and immune function, particularly in people who are deficient; K2 (as MK-7) is studied for directing calcium toward bone rather than arterial tissue, which is the rationale for pairing them.
