Allergy Research Group Zinc Citrate 50
Brand: Allergy Research Group · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that this product provides a high dose of calcium, not zinc as the name might suggest. Our assessment: Calcium is a critical mineral, but at 50 mg per serving, this is a moderate dose that falls below the 1,000 mg RDA for most adults [NIH ODS]. You should not rely on this supplement alone to meet your daily calcium needs.
How it works
Think of calcium as a structural builder for your bones and a calming signal for your muscles. It supports bone mineralization and density, and it helps your muscles relax and your nerves communicate properly [NIH ODS]. Without enough calcium, your body will pull it from your bones, which can weaken them over time.
Safety profile
FDA has received a total of 592,059 adverse event reports for products containing calcium. Side effects from very high intake include poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data]. Additionally, calcium supplements can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by assessing your total daily calcium intake from food and other supplements. If you take this product, take it separately from any medications listed above by at least two hours. Do not exceed 2,000 mg of total calcium per day from all sources without medical supervision [NIH ODS]. For most adults, a combined diet and supplement goal of 1,000 mg daily is a safe starting point [NIH ODS].
