NOW Full Spectrum Mineral Caps
Brand: NOW · Form: CAPSULE [E0159]
Our assessment
The evidence shows that this supplement provides calcium, a mineral essential for bone health. For most adults, the goal is to meet the Recommended Dietary Allowance through diet and supplementation if needed, but you must be aware of the safety limits. Data on this specific product's full mineral profile is limited, so we focus on the primary active ingredient: calcium [NIH ODS].
How it works
Think of calcium as a structural foundation for your bones. It supports bone mineralization and density, and it is critical for neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA has received 592,059 adverse event reports for products in this category. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine levels can cause 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 [FDA data] [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by assessing your total daily calcium intake from all sources (food and supplements). Do not exceed the tolerable upper intake level of 2,500 mg per day for adults. Take calcium supplements with food and separate from thyroid medication or antibiotics by at least 2 hours. Data not available on the specific dosage or other mineral levels in this product, so consult your healthcare provider before starting [NIH ODS].
