Major Zinc 50 mg
Brand: Major · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that this product, Major Zinc 50 mg, contains calcium as its active ingredient. Our assessment: Calcium is essential for bone health, but taking a 50 mg dose is far below the standard supplemental dose for this mineral. The RDA for most adults is 1,000 mg per day, so this product provides only 5% of that target [NIH ODS]. You should not rely on this supplement as your primary source of calcium.
How it works
Think of calcium as a structural builder for your body. It supports bone mineralization, helping to maintain bone density, and is also critical for neuromuscular relaxation and nerve signaling [NIH ODS]. For these benefits, you would need a much higher daily intake, typically from food or a dedicated calcium supplement.
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available. Data not available for side effects specific to this 50 mg dose. However, high calcium intake from any source can cause constipation, nausea, and abnormal heart rhythms [NIH ODS]. You should also be aware that calcium supplements can reduce the absorption of medications like tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Do not use this product as a meaningful source of calcium. If you are taking it for a different reason, the data does not support that use. For bone health, aim for 1,000 mg of calcium daily from diet or a standard calcium supplement, and always take it separately from your thyroid or antibiotic medications [NIH ODS] [FDA data].
