Source Naturals Magnesium Malate
Brand: Source Naturals · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that magnesium malate is a well-absorbed form of magnesium, but for this specific product, the data on the ingredient calcium is what is available. Our assessment: Calcium supports bone density and muscle relaxation, but you need to be cautious with total intake from all sources [NIH ODS]. The FDA has received 592059 total adverse event reports across all supplement categories, though this number is not specific to this product [FDA data].
How it works
Think of calcium as a structural builder and a signal regulator. It supports bone mineralization by depositing minerals into your skeleton, and it helps your muscles relax and your nerves send signals properly [NIH ODS]. This makes it essential for daily function, but your body tightly controls calcium levels, so balance is key.
Safety profile
High calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from excessive levels include 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]. Additionally, calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. The specific number of adverse event reports for this product is data not available.
Our recommendation
Data not available for a specific dosage recommendation for this product. Before taking this calcium-containing supplement, check your total daily calcium intake from food and other supplements. If you take any medications listed in the interactions section, separate your calcium supplement by at least 2 hours [NIH ODS]. Always consult your healthcare provider before starting a new supplement regimen.
