Right now the best value across our full Manganese catalog is at $0.04 per serving.
Manganese is an essential trace element that acts as a cofactor for many enzymes, including manganese superoxide dismutase, arginase, and pyruvate carboxylase; through these enzymes it is involved in amino acid, cholesterol, glucose, and carbohydrate metabolism, reactive oxygen species scavenging, bone formation, reproduction, and immune response, and it also plays a role in blood clotting and hemostasis in conjunction with vitamin K. Because of its role as an enzyme cofactor in bone formation, scientists have examined associations between circulating manganese levels, bone mineral density, and osteoporosis, but per the NIH the evidence is very limited and inconsistent, no clinical trials have evaluated manganese supplementation alone on bone health, and more research is needed. Manganese has also been studied in relation to diabetes since it is involved in glucose, carbohydrate, and lipid metabolism; however, studies have found associations with both increased and decreased blood manganese levels and type 2 diabetes (including a U-shaped association), human clinical trials are lacking, and more research is needed to determine whether manganese plays any role in the development of diabetes. — per the NIH Office of Dietary Supplements; not medical advice.
In dietary supplements, manganese is present in many different forms, including amino acid chelates (such as manganese bisglycinate chelate, manganese glycinate chelate, and manganese aspartate), as well as manganese gluconate, manganese picolinate, manganese sulfate, manganese citrate, and manganese chloride. According to the NIH, no data are available on the relative bioavailability of these different forms of supplemental manganese, and the Supplement Facts label declares the amount of elemental manganese rather than the weight of the entire manganese-containing compound.
Manganese is present in a wide variety of foods, including whole grains, clams, oysters, mussels, nuts, soybeans and other legumes, rice, leafy vegetables, coffee, tea, and many spices such as black pepper; the top sources in U.S. adults' diets are grain products, tea, and vegetables. Among selected foods, cooked blue mussels are especially rich (5.8 mg, 252% DV per 3 ounces), followed by dry-roasted hazelnuts, pecans, and brown rice — per the NIH Office of Dietary Supplements.
Manganese deficiency is very rare in humans, and its signs and symptoms have not been firmly established; according to the fact sheet, no known groups of people are likely to have inadequate manganese intakes. The very limited evidence suggests deficiency might cause bone demineralization and poor growth in children; skin rashes, hair depigmentation, decreased serum cholesterol, and increased alkaline phosphatase activity in men; and altered mood and increased premenstrual pain in women — per the NIH Office of Dietary Supplements.

Manganese uses Adequate Intakes (AIs), not an . For adults 19+, the AI is 2.3 mg/day for men and 1.8 mg/day for women. During pregnancy it is 2.0 mg and during lactation 2.6 mg. AIs for children range from 0.003 mg (birth-6 months) up to 1.9 mg (boys 9-13). — per the NIH Office of Dietary Supplements; general information, not medical advice.
Yes. The is 11 mg/day for adults 19+ (9 mg for ages 14-18, less for younger children). Toxicity mainly affects the central nervous system, causing tremors, muscle spasms, tinnitus, hearing loss, and unsteadiness, and can progress to Parkinson's-like neuromotor impairments. — per the NIH Office of Dietary Supplements; general information, not medical advice.

No evidence shows manganese toxicity from high dietary intakes, but toxicity has occurred in welders and miners who inhaled manganese dust and in people drinking water with high manganese levels; it mainly affects the central nervous system, causing tremors, muscle spasms, tinnitus, hearing loss, unsteadiness, and effects that can progress to neuromotor impairments similar to Parkinson's disease. The Food and Nutrition Board set Tolerable Upper Intake Levels of 11 mg for adults 19+ years (including pregnancy and lactation), 9 mg for ages 14–18, 6 mg for ages 9–13, 3 mg for ages 4–8, and 2 mg for ages 1–3 — per the NIH Office of Dietary Supplements.
