The Science Behind Stack™
The vitamins and minerals in Stack deliver clear, science-backed benefits, supported by peer-reviewed studies and clinical evidence.
Day Stack Research
Day Stack™ delivers a precisely balanced spectrum of vitamins, minerals, and cofactors that fuel cellular energy production, sharpen cognitive performance, and strengthen immune defenses. Each ingredient is backed by peer-reviewed research, working in synergy to sustain vitality, resilience, and metabolic balance all day long.
Steady energy metabolism
Vitamins B1, B2, B6, B12 as well as iron act as indispensable cofactors in the Krebs cycle and electron-transport chain, helping every cell turn food into ATP for calm, all-day vitality.
Robust immune defense
Vitamin C sparks leukocyte activity, vitamin D3 modulates both innate and adaptive responses, vitamin A maintains mucosal barriers, while zinc and selenium support antibody and cytokine production.
Sharper focus and memory
Magnesium L-threonate crosses the blood-brain barrier to enhance synaptic plasticity, and B-complex nutrients drive neurotransmitter synthesis for clear thinking.
Balanced mood and stress resilience
Vitamin B6 helps make serotonin and GABA, magnesium calms excitatory neurons, and vitamin C tempers cortisol spikes, promoting a composed response to daily stressors.
Strong bones and muscle function
Calcium supplies the mineral matrix, vitamin D3 boosts calcium absorption, K1 + K2 guide calcium into bone, and magnesium supports muscle contraction and relaxation.
Heart and blood-pressure support
Potassium and magnesium aid vascular relaxation and sodium balance, while vitamin K2 helps keep calcium from depositing in arterial walls for healthy circulation.
Antioxidant cellular protection
Vitamins C and E neutralize free radicals, selenium recycles glutathione peroxidase and copper supports superoxide dismutase, shielding tissues from oxidative damage.
Radiant skin, hair and nails
Biotin fortifies keratin structure, zinc supports wound healing and sebum balance, and vitamin A drives healthy skin cell turnover for a clear complexion and stronger strands.
Healthy thyroid and metabolic rate
Iodine is the raw material for T3 and T4 hormones, while zinc assists their activation, sustaining calorie burn, temperature regulation and overall metabolism.
Red blood cell formation and oxygen delivery
Iron builds heme, folate and B12 enable DNA synthesis in erythroblasts, keeping hemoglobin levels up for better endurance.
Electrolyte and hydration balance
Potassium and magnesium keep nerve impulses firing and muscles contracting smoothly, supporting fluid balance and preventing afternoon slumps.
Clear vision and eye health
Beta-carotene converts to retinal for low-light vision, and zinc helps transport vitamin A in the retina, guarding against night-vision problems and macular decline.
Balanced blood sugar and insulin sensitivity
Zinc modulates insulin-receptor signaling, and adequate magnesium supports carbohydrate metabolism, helping maintain steady glucose levels.
Resilient connective tissue and joint comfort
Vitamin C is a co-factor for proline and lysine hydroxylation, while copper activates lysyl oxidase, together strengthening collagen cross-links in skin, tendons and vessels.
DNA synthesis and cellular renewal
Folate donates one-carbon units for nucleotide production, and zinc stabilizes DNA polymerases, enabling proper cell division and repair across the body.
Night Stack Research
Night Stack™ combines targeted minerals and cofactors that calm the nervous system, deepen restorative sleep, and accelerate overnight repair. Supported by peer-reviewed research, its precisely timed nutrients work in harmony with your body's natural rhythms to enhance recovery, hormonal balance, and morning clarity.
Fall asleep faster
Calcium boosts pineal melatonin output, shortening the time it takes to drift off.
Deeper, uninterrupted sleep cycles
Magnesium glycinate enhances sleep depth, zinc fine-tunes sleep architecture, and potassium helps stop cramp-triggered awakenings.
Wake up feeling restored
Better REM and slow-wave continuity from balanced magnesium and zinc translates into brighter mood and morning energy.
Calmer mind and lower bedtime stress
Magnesium supports GABA activity and moderates cortisol, while zinc helps steady stress-related hormones.
Overnight muscle repair and protein synthesis
Zinc drives anabolic hormone and ribosomal activity, and magnesium supplies the ATP needed to rebuild tissue after training.
Healthy bone remodeling while you sleep
Evening calcium aligns with the nightly surge in bone turnover, and magnesium plus manganese activate osteoblast enzymes for stronger skeletal matrix.
Antioxidant defense against nightly oxidative stress
Manganese-dependent MnSOD and zinc-dependent enzymes sweep up mitochondrial free radicals created during deep recovery.
Balanced heart rhythm and comfortable blood pressure
Potassium and magnesium aid vascular relaxation and electrical stability, while calcium helps smooth-muscle tone.
Immune upkeep through the night
Zinc supports T-cell and natural-killer cell function, keeping defenses primed while you rest.
Stable overnight blood sugar and insulin sensitivity
Magnesium improves insulin-receptor signaling, reducing nocturnal glucose swings.
Hormonal balance for growth-phase recovery
Adequate zinc at bedtime supports the surge of growth hormone and testosterone that peaks during deep sleep.
Connective-tissue and collagen repair
Manganese acts as a cofactor for collagen-forming enzymes, and zinc assists cross-linking, rejuvenating joints, tendons and skin.
Restless-leg relief and reduced nighttime twitching
Magnesium and potassium normalize nerve impulses, easing the crawling sensations that can disturb sleep.
Metabolic enzyme activation for overnight maintenance
Hundreds of magnesium- and manganese-dependent enzymes quietly process carbs, fats and amino acids so you wake up metabolically ready.
