Nutrilite Vitamin D
Brand: Nutrilite · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that for many people, calcium is a necessary mineral for bone health. However, based on the data, we recommend you do not exceed the established upper intake levels and consult your doctor before starting a calcium supplement, as high intakes carry significant risks [NIH ODS].
How it works
Think of calcium as a structural builder and a cellular messenger. It supports bone mineralization and density, and it is critical for neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high levels 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. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS] [FDA data].
Our recommendation
Get your calcium from food first. If you take a supplement, be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data on the specific product "Nutrilite Vitamin D" is not available. Always separate calcium supplements from these medications by at least two hours [NIH ODS].
