Ingredient research · Protein

Protein is a concentrated way to supply amino acids needed to build and repair body tissues. Supplementation can help meet higher or otherwise unmet protein needs, supporting muscle growth and exercise recovery when paired with training and helping preserve muscle during aging, illness, or calorie restriction.

• Supports selected muscle-strength outcomes when increased protein intake accompanies resistance training.
• Supports selected muscle-mass outcomes when protein supplementation accompanies resistance exercise in community-dwelling older adults with sarcopenia.
• Supports a selected post-meal hunger outcome under a controlled high-protein weight-loss diet.

Ingredient research · Vitamin A

Vitamin A is an essential fat-soluble nutrient that enables normal vision, especially in dim light, and helps maintain immune defenses, skin and other epithelial tissues, growth, and reproduction. Supplementation can prevent or correct deficiency when intake or absorption is inadequate, benefiting visual, immune, and developmental health.

• Supports maternal and breast-milk vitamin A status, particularly where baseline stores are low.
• Supports hemoglobin response in some anemic or vitamin A-deficient populations, including when added to iron and folate.
• Supports reducing bacterial-vaginosis incidence and prevalence during pregnancy and postpartum follow-up in a studied deficient setting.

Ingredient research · Vitamin D

Vitamin D is a hormone-like nutrient that helps the body absorb calcium and maintain healthy bones and muscle function. Supplementation can reliably prevent or correct low vitamin D status, particularly when sun exposure is limited, while broader immune, cardiovascular, and metabolic benefits are less certain.

• Supports bone-density and fracture- or fall-related outcomes.
• Supports muscle-strength outcomes, including lower-limb strength.
• Supports glycemic-marker and insulin-sensitivity outcomes in studied metabolic populations.
• Supports respiratory-infection-risk outcomes across studied age groups.

Ingredient research · Vitamin B2

Vitamin B2 is riboflavin, an essential nutrient that helps enzymes release energy from food and supports normal red blood cell, skin, and nervous-system function. Supplementation reliably prevents or corrects deficiency, and regular use can reduce migraine frequency and severity in some people.

• Supports blood-pressure control in treated hypertensive adults with the MTHFR 677TT genotype.

Ingredient research · Niacin

Niacin is vitamin B3, essential for enzymes that convert food into energy and support normal skin and nervous-system function. Supplementation prevents or corrects deficiency; in high-dose nicotinic acid form it can alter cholesterol and triglycerides, but this pharmacologic use is distinct from routine nutritional supplementation.

• Supports favorable changes in selected cholesterol fractions, including LDL, HDL, and total cholesterol, in studied metabolic and diabetes populations.
• Supports favorable fasting-triglyceride changes in studied adults with diabetes or metabolic dysregulation.

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.

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.

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.

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.

Ingredient research · Phosphorus

Phosphorus is an essential dietary mineral that helps build bones and teeth and is integral to cellular energy, cell membranes, and acid–base balance. Supplements are mainly relevant when intake or absorption is inadequate; most diets already provide enough, and excess phosphorus can be problematic, especially with impaired kidney function.

Ingredient research · Magnesium

Magnesium is an essential mineral that enables normal muscle and nerve function, energy production, heart rhythm, and bone maintenance. Supplements can correct low magnesium status and, depending on the formulation, may also help with constipation, muscle cramps, or migraine prevention in some people.

Ingredient research · Chlorella

Chlorella is a nutrient-dense freshwater microalga supplied as powders or tablets, providing protein, carotenoids, and varying amounts of vitamins and minerals. Studies suggest it may modestly benefit cholesterol, blood pressure, and glucose control, while popular detox and immune claims remain uncertain.

• Supports total- and LDL-cholesterol responses during a dietary cholesterol challenge.
