Natrol Calcium D-Glucarate
Brand: Natrol · Form: TABLET [E0155]
Our assessment
Our assessment: Calcium D-Glucarate from Natrol is a specific combination supplement, but the data available focuses on the calcium component. The evidence shows that calcium is essential for bone health, 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 structural builder for your bones and a signal regulator for your nerves and muscles. It supports bone mineralization and density, and it is critical for muscle relaxation and nerve signaling [NIH ODS].
Safety profile
From 592,059 total adverse event reports across all products, the data shows calcium has specific risks. High intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high blood and urine calcium levels include 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].
Our recommendation
Proceed with caution. Do not exceed the RDA without a doctor’s guidance. Take calcium supplements separately from medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin, as calcium can reduce their absorption [NIH ODS]. Data not available for the D-Glucarate component specifically.
