Vitamin C
Ingredient research · Vitamin C
Vitamin C is an essential water-soluble nutrient that supports collagen production, antioxidant defenses, and the normal function of immune cells. Supplementation reliably prevents or corrects deficiency, can improve absorption of plant-based iron, and may modestly shorten the duration of common colds when taken regularly.
- Supports lower common-cold risk during brief periods of severe physical exercise or cold stress.
- Supports circulating Vitamin C status across studied healthy and clinical populations.
- Supports short-term blood-pressure and endothelial-function outcomes in studied adults.
- Supports fasting-glucose and HbA1c outcomes in adults with type 2 diabetes.

Vitamin B6
Ingredient research · Vitamin B6
Vitamin B6 is an essential nutrient that helps enzymes process amino acids and supports neurotransmitter, hemoglobin, and immune function. Supplementation reliably corrects deficiency and can reduce nausea during pregnancy; outside these uses, it is most relevant when intake or absorption is inadequate.
- Supports depressive-symptom measures in premenopausal women with hormone-related contexts.

Folate
From 400 mcg L-5-Methyltetrahydrofolate
Ingredient research · Folate
Folate is vitamin B9, an essential nutrient needed for DNA synthesis, cell division, and healthy red blood cell formation. Supplementation is especially important before conception and in early pregnancy because adequate folate reliably reduces neural tube defect risk, and it can also correct folate-deficiency anemia.
- Supports homocysteine measures in women with PCOS and adults with metabolic syndrome.
- Supports insulin and beta-cell-function markers in women with PCOS or cervical intraepithelial neoplasia.
- Supports selected lipid-panel and vascular markers in women with PCOS and adults with metabolic syndrome.
- Supports selected inflammation and oxidative-stress biomarkers in PCOS, metabolic syndrome, or cervical intraepithelial neoplasia.

Vitamin B12
Ingredient research · Vitamin B12
Vitamin B12 is an essential nutrient needed for red blood cell formation, DNA synthesis, and normal nerve function. Supplementation reliably prevents or corrects deficiency—especially when intake or absorption is limited—and may improve anemia, fatigue, or neurologic symptoms caused by low B12, but is not a general energy booster when status is adequate.
- Supports vitamin B12 status and responsive deficiency markers in low-status populations, including maternal and breast-milk status during pregnancy and early lactation.

- A vitamin B-12 supplement of 500 μg/d for eight weeks does not normalize urinary methylmalonic acid or other biomarkers of vitamin B-12 status in elderly people with moderately poor vitamin B-12 status.
- Vitamin B-12 supplementation during pregnancy and early lactation increases maternal, breast milk, and infant measures of vitamin B-12 status.

Iron
Ingredient research · Iron
Iron is an essential mineral needed to make hemoglobin and carry oxygen throughout the body. Supplementation can reliably prevent or correct iron-deficiency anemia, helping restore energy, exercise capacity, and cognitive function when low iron is the cause; it is also commonly used when requirements rise, such as during pregnancy.
- Supports hemoglobin and iron stores in menstruating women, especially when iron status is low.
- Supports reduced subjective fatigue in iron-deficient adults without anemia.
- Supports selected maximal and submaximal exercise-performance measures in women of reproductive age, particularly those who are iron-deficient or trained.
- Supports selected attention and concentration outcomes in older children and women.
