Energy & Performance
For the gym, the trail, or just getting through the afternoon. Pre-workouts, CoQ10, beetroot, electrolytes, and athletic performance supplements.
CoQ10 (Ubiquinol)
Heart failure support, statin-induced myopathy relief, cellular energy production, antioxidant protection
Beetroot Powder
Improves exercise endurance, reduces blood pressure, and lowers the oxygen cost of submaximal exercise via dietary nitrate conversion to nitric oxide.
Pre-Workout Formulas
Enhanced exercise performance through clinically dosed caffeine, citrulline, beta-alanine, and creatine
Electrolyte Powders
Replaces sodium, potassium, and other electrolytes lost during prolonged exercise, heat exposure, or acute illness
Taurine
Blood pressure support, exercise endurance, cardiovascular and metabolic health
L-Carnitine
Exercise recovery, post-MI cardiovascular support, modest fat-loss adjunct, and male fertility
Acetyl-L-Carnitine
Diabetic peripheral neuropathy, cognitive aging support, mitochondrial energy in brain and nerve tissue
Spirulina
Modest improvements in lipid panel, blood pressure, exercise endurance, and inflammatory markers from a nutrient-dense microalgae
Phosphatidylserine
Modest support for age-related memory complaints; cortisol blunting in trained athletes at higher doses
Tart Cherry
Exercise recovery (DOMS, strength, oxidative stress) and modest sleep quality improvements
L-Arginine
Nitric oxide precursor for vasodilation, mild ED support, and amino acid pool
Cordyceps
Aerobic capacity and exercise tolerance, immune modulation, anti-fatigue support
Shilajit
Traditional Ayurvedic resin with limited but real evidence for testosterone support in older or subfertile men; most other claims are speculative
Agmatine Sulfate
Sold heavily in pre-workouts for 'pumps' and as a neuropathic pain or mood aid; the marketing is far ahead of the human evidence on every one of those claims
NMN (Nicotinamide Mononucleotide)
Raises blood NAD+ levels; preliminary signals for insulin sensitivity, physical function, and aerobic capacity in midlife and older adults
Nicotinamide Riboside (NR)
NAD+ elevation as a cellular metabolism support; downstream functional benefits in humans remain unconfirmed
TMG (Trimethylglycine / Betaine Anhydrous)
Homocysteine lowering via methylation support, with modest power-output and muscle endurance signal in resistance-trained men
Apigenin
Plant flavone from chamomile and parsley, studied in cells and rodents for relaxation, NAD+/CD38 modulation, and longevity; no high-quality human RCTs on the standalone supplement
MCT Oil
Rapid ketone fuel, modest body composition support when substituted for long-chain fats, and a studied adjunct in mild Alzheimer's cognitive decline
L-Glutamine
Fuel for intestinal cells and immune cells; studied for gut barrier support, IBS-D symptoms, sickle cell crisis reduction, and recovery in specific clinical settings
Spermidine
Marketed as a natural polyamine that supports cellular renewal (autophagy); the human evidence for downstream cognitive or longevity benefits is small and the largest RCT missed its primary endpoint
Pterostilbene
Polyphenol with better oral bioavailability than resveratrol; small human RCT base for blood pressure and as a co-ingredient in NAD+ stacks
Beta-Alanine
Supports exercise capacity in high-intensity efforts lasting 1-4 minutes by raising intramuscular carnosine and buffering acid build-up
PQQ (Pyrroloquinoline Quinone)
Mitochondrial cofactor marketed for cellular energy and cognitive support; small, mostly industry-funded human trials at 20mg/day
Astragalus
Traditional immune and qi tonic with a long Chinese herbal history; modern human RCT evidence is limited and most positive trials are chemotherapy or kidney-disease adjuncts, not stand-alone immune support in healthy adults.
Magnesium Malate
General magnesium repletion with a malic acid pairing often used for morning dosing, energy, and fibromyalgia-related muscle discomfort
HMB (Beta-Hydroxy-Beta-Methylbutyrate)
Supports lean body mass preservation and recovery, with the strongest signals in older adults, during bed rest, in novice trainees, and during caloric deficit
