Exchange Select Vitamin B6 100 mg
Brand: Exchange Select · Form: TABLET [E0155]
Our assessment
The evidence shows that calcium is a critical mineral for bone health, but the data on high-dose supplementation includes important safety considerations you need to know [NIH ODS]. For a general audience, the primary benefit is supporting bone density and nerve signaling, though the risks associated with excessive intake are significant [NIH ODS].
How it works
Think of calcium as a structural foundation for your bones. It supports bone mineralization and density, and it also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. For proper absorption, your body requires adequate vitamin D levels [NIH ODS].
Safety profile
The FDA received a total of 592,059 adverse event reports across all supplements, though data for calcium-specific reports is not available [FDA data]. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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 getting your calcium primarily from food sources and discussing supplementation with your doctor. If you use a supplement, do not exceed 1,000–1,200 mg total daily intake from all sources unless your physician advises otherwise [NIH ODS]. Be aware of the potential interactions with medications and the risk of adverse effects from high levels [NIH ODS].
