Our assessment

The evidence shows that this product, Douglas Laboratories Amino-Mag 200, contains calcium. Our assessment is that calcium is a foundational mineral for bone health and nerve function, but you need to be careful with dosing and timing to avoid side effects and drug interactions [NIH ODS].

How it works

Think of calcium as a dual-action mineral. First, it supports bone mineralization by helping deposit minerals into your skeleton for density. Second, it acts as a neuromuscular relaxant, supporting proper muscle relaxation and nerve signaling throughout your body [NIH ODS].

Safety profile

FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Very high 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 [NIH ODS] [FDA data].

Our recommendation

Start with the lowest effective dose and take calcium separately from medications. Calcium can reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. If you take any of these, separate your calcium dose by at least 2 hours. Data not available on the exact magnesium content of this specific product.
