Nature Made Calcium Citrate + Magnesium
Brand: Nature Made · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that this product combines three important nutrients, but the key ingredient is calcium. Our assessment: you may benefit from this supplement if you are looking to support your bone health, but you must be cautious about the total amount of calcium you consume from all sources [NIH ODS].
How it works
Think of calcium as the building block for your bones. It supports bone density and mineral deposition, which is critical for maintaining strong skeletal structure [NIH ODS]. Additionally, calcium plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports for products in this category. You should be aware that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Extremely high levels of calcium 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you calculate your total daily calcium intake from food and other supplements before adding this product. If you take any of the medications listed (such as thyroid medication or antibiotics), take this supplement at least two hours apart [NIH ODS]. Start with a low dose and watch for side effects like constipation or nausea [NIH ODS].
