If you’ve ever wondered how much manganese you should take, you’re not alone. This trace mineral helps bone formation, metabolism, and antioxidant defenses, but only when you get the right amount. Below we break down the numbers you need, where to find manganese in food, and when a supplement might be useful.
Health agencies set the Recommended Dietary Allowance (RDA) at 2.3 mg per day for men and 1.8 mg for women. For teens and kids the numbers drop to 1.6–2.0 mg, depending on age. Most people hit these targets just by eating a balanced diet that includes whole grains, nuts, seeds, and leafy greens like spinach.
If you’re considering a supplement, the typical dose ranges from 1 mg to 5 mg per day. Anything under 10 mg is generally regarded as safe for short‑term use, but going higher increases the chance of toxicity. Always check the label – many multivitamins already contain the RDA amount.
Because the body stores only a tiny amount of manganese, excess is usually expelled in urine and bile. Still, chronic intake above 11 mg per day can lead to neurological symptoms like tremors, anxiety, or difficulty walking. High doses may also interfere with iron absorption, so people with anemia should be cautious.
On the flip side, a deficiency is rare but can cause poor bone growth, slow wound healing, and elevated blood sugar. If you notice fatigue, frequent infections, or unexplained bruising, it might be worth checking your manganese status with a doctor.
Bottom line: aim for the RDA through food first, add a low‑dose supplement only if you have a documented shortfall, and never exceed 10 mg daily without professional guidance. Listening to your body and staying within these limits keeps manganese working for you, not against you.
