Precursor for NAD⁺ production. Essential for cellular energy and DNA repair.
300+ studies availableNicotinamide supplementation increased NAD⁺ levels by up to 60% and improved mitochondrial function in humans.
View Study →NAD⁺ levels decline with age. Supplementation improved metabolic function and showed neuroprotective effects.
View Study →Critical for mitochondrial energy production and cellular protection.
200+ studies available200mg CoQ10 daily improved cardiovascular function and reduced oxidative stress markers significantly.
View Study →CoQ10 levels decline up to 50% with age. Supplementation restored mitochondrial efficiency and reduced age-related decline.
View Study →Adaptogen for stress balance and cortisol regulation. Supports immune function.
150+ studies available300mg Ashwagandha twice daily reduced cortisol levels by 28% and significantly improved stress scores.
View Study →Ashwagandha supplementation increased muscle strength, reduced recovery time, and improved body composition.
View Study →Adaptogen for mental and physical resilience. Reduces fatigue and enhances focus.
100+ studies available170mg Rhodiola twice daily significantly reduced fatigue and improved concentration under stress conditions.
View Study →Rhodiola showed comparable effects to sertraline in improving mood, with significantly fewer side effects.
View Study →Rhodiola reduced exhaustion after extreme exertion and supported immune function. Improved recovery time.
View Study →Essential mineral for over 300 enzymatic reactions. Supports muscle and nerve function.
100+ studies availableHigher magnesium intake associated with better sleep quality, longer sleep duration, and reduced daytime fatigue.
