Major Calcium 600 mg
Brand: Major · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that calcium is essential for bone health, but you need to be careful about the total amount you take. Major Calcium 600 mg provides a significant dose, and it is critical to account for calcium from food to avoid exceeding safe upper limits [NIH ODS].
How it works
Think of calcium as a structural building block for your bones. It supports bone density and mineral deposition. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports for products containing this ingredient. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer. High levels in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data].
Our recommendation
Start by calculating your daily calcium intake from food. If you already get 700-800 mg from your diet, you likely do not need this supplement. If you do take it, take it with food and separate it by at least two hours from medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
