Natrol Calcium D-Glucarate
Brand: Natrol · Form: TABLET [E0155]
Our assessment
The evidence shows that calcium is a well-established mineral for bone health, but you need clear dosing guidance. Data on the specific combination with D-glucarate in this product is limited, so we focus on the calcium component which is known to be effective when taken correctly [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton — it supports bone mineralization and density. It also acts as a nerve signal regulator, helping your muscles relax and your nerves communicate properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, though data for this specific product is not available separately. High calcium intakes can cause constipation, nausea, and extreme tiredness. You should be aware that very high levels in the blood may lead to poor kidney function and abnormal heart rhythms [NIH ODS] [FDA data].
Our recommendation
Start by checking your total calcium intake from food and other supplements. Calcium can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine — take this supplement at least 2 hours apart from those drugs [NIH ODS]. For specific dosing guidance on D-glucarate, data is not available.
