Glucosamine

Glucosamine is an amino sugar naturally produced in the body, essential for cartilage synthesis. B-grade evidence for osteoarthritis symptom relief with small effect size. IMPORTANT: Glucosamine SULFATE appears superior to hydrochloride - the sulfate form is what's been studied in positive trials. Effect is modest and takes 2-3 months to manifest. Popular combination with chondroitin. Derived from shellfish (allergen concern) or corn (vegan). GAIT trial showed no benefit over placebo, creating controversy.

Boron

Boron is a trace mineral often marketed for testosterone enhancement, but this claim lacks strong support. B-GRADE for C-reactive protein reduction (3 studies, 178 participants, moderate decrease). C-GRADE for estrogen effects (mixed), dysmenorrhea symptoms (moderate improvement), CRP in arthritis contexts, and knee pain. D-GRADE for blood glucose, body fat, and serum calcium (no effect). Anti-inflammatory effects are the most consistent finding. Testosterone claims are based on weak evidence from very small studies.

Manganese

2 shared conditions · 14 outcomes

Manganese is an essential trace mineral required for numerous enzymatic reactions in the body. It serves as a cofactor for manganese superoxide dismutase (MnSOD, the primary mitochondrial antioxidant), arginase (urea cycle), glutamine synthetase (ammonia detoxification), and pyruvate carboxylase (gluconeogenesis). Manganese is critical for bone formation, glucose metabolism, wound healing, and neurotransmitter synthesis. The Adequate Intake (AI) is 2.3mg/day for men and 1.8mg/day for women. Deficiency is rare due to widespread dietary availability but can cause impaired growth, skeletal abnormalities, and altered glucose tolerance. Toxicity from excessive intake (primarily occupational inhalation) can cause manganism, a Parkinson-like neurological syndrome.
