Vitamin Dvitamin
Vitamin D is a fat-soluble nutrient that supports bone health, immune function, and general well-being. It helps the body regulate calcium and phosphate levels, which are necessary for maintaining bone mineralization and a healthy immune response.
Good for
Anti-AgingHighest effectFoundational for bone health, immune regulation, and mood, all of which are critical for healthy aging. Deficiency is extremely common and worsens with age.
Anti-Inflammatory SupportHighest effectActs as a crucial immunomodulatory hormone, regulating the production of inflammatory cytokines and promoting a balanced immune response.
Bone HealthHighest effectEssential for intestinal absorption of calcium, the primary mineral component of bone.
Brain HealthHighest effectActs as a neurosteroid hormone, essential for mood, executive function, and long-term neuroprotection.
Cardiovascular SupportHighest effectSupports cardiovascular function, with correcting a deficiency particularly relevant.
Cognitive SupportHighest effectA foundational neurosteroid essential for neuroprotection and overall cognitive function.
Digestive HealthHighest effectFundamental for regulating immune function within the gut and strengthening the intestinal barrier.
EnergyHighest effectPlays a key role in mitochondrial function, and deficiency is strongly correlated with fatigue, muscle weakness, and low mood, all of which impact perceived energy levels.
FitnessHighest effectEssential for optimal hormone function, bone health, and immune support, all critical for athletic performance and recovery.
General HealthHighest effectFoundational for immune function, bone health, and mood regulation; deficiency is extremely common.
Hair HealthHighest effectStimulates new hair follicles and helps regulate the hair growth cycle; deficiency is linked to alopecia.
ImmunityHighest effectFoundational for immune cell function; deficiency is strongly linked to increased susceptibility to infections, particularly respiratory ones.
Mental FocusHighest effectA foundational neurosteroid essential for brain health, neurotransmitter regulation, and cognitive function.
Metabolism BoostHighest effectFunctions as a hormone to regulate metabolic pathways and improve insulin sensitivity, with deficiency strongly linked to metabolic syndrome.
Mood SupportHighest effectFunctions as a neurosteroid hormone essential for brain health, with widespread deficiency being strongly linked to low mood and depression.
Muscle GainHighest effectEssential for optimal muscle function and supports the production of anabolic hormones like testosterone.
Stress ReliefHighest effectA foundational vitamin-hormone for mood regulation and nervous system resilience, often depleted by stress.
Testosterone SupportHighest effectFunctions as a pro-hormone and is fundamentally linked to testosterone production, with deficiency strongly correlated with low levels.
Weight LossHighest effectCorrects for common deficiencies linked to metabolic dysfunction and fat accumulation, supporting optimal hormonal health.
Heart HealthHigh effectFunctions as a hormone that helps regulate blood pressure and reduce inflammation; correcting common deficiencies is strongly associated with improved cardiovascular outcomes.
Joint HealthModerate effectEssential for bone health supporting the joint and for modulating immune responses to control inflammation.
Vision SupportModerate effectModulates inflammation and supports retinal health, with deficiency linked to higher AMD risk.
Nail HealthSituational effectSupports keratinocyte proliferation and calcium balance, indirectly influencing nail plate integrity.
Sleep SupportSituational effectMay affect sleep quality in some circumstances, but it is not an established treatment for insomnia.
Weight GainSituational effectFunctions as a hormone in the body and is linked to muscle strength and optimal testosterone levels, making it important for athletic performance.
