NOW Cayenne 500 mg
Brand: NOW · Form: CAPSULE [E0159]
Our assessment
The evidence shows that the primary ingredient in NOW Cayenne 500 mg is not cayenne, but calcium. Our assessment is that this product is a calcium supplement, not a cayenne supplement. Calcium is a well-supported mineral for bone health, but you should be aware of its specific risks and limitations [NIH ODS].
How it works
Calcium works as a master regulator for your bones and nerves. It supports bone mineralization and density, and it helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, side effects can include constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms at high levels. High calcium intakes might also increase the risk of heart disease and prostate cancer [FDA data] [NIH ODS]. Calcium can reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Because the label lists calcium as the ingredient, we recommend you confirm the actual product you hold matches your expectations. If you are taking this for calcium, start with a standard dose and get your blood levels checked. Be aware of the medication interactions listed above [NIH ODS]. If you were seeking a cayenne supplement, this product data does not support that use.
