Douglas Laboratories Calcium D-Glucarate
Brand: Douglas Laboratories · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Douglas Laboratories Calcium D-Glucarate is primarily a calcium supplement. Based on the data, calcium supports bone density and nerve signaling [NIH ODS]. However, you should be aware that high intakes may pose risks, including a potential increased risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural builder for your bones and a signal messenger for your muscles and nerves. It supports bone mineralization and neuromuscular relaxation, helping your muscles relax and your nerves communicate properly [NIH ODS].
Safety profile
FDA has received 592,059 total adverse event reports for this product type. Specific side effects from high calcium levels include poor muscle tone, poor kidney function, 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 medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start with a low dose and be cautious about your total daily calcium intake from all sources. Check with your doctor before starting, especially if you take any of the listed medications or have a history of kidney problems or heart disease [NIH ODS]. Data on the specific benefits of the D-glucarate component beyond calcium is not available.
