NOW BioCell Collagen
Brand: NOW · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that BioCell Collagen is a supplement that provides calcium, a mineral essential for bone health. Our assessment is that while calcium supports bone density, you should be aware that taking it in high amounts carries specific risks [NIH ODS].
How it works
Think of calcium as a structural building block for your bones and a key player in nerve signaling. It supports bone mineralization and helps your muscles relax after they contract [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Side effects of high calcium levels include constipation, nausea, weight loss, extreme tiredness, frequent urination, and abnormal heart rhythms [NIH ODS] [FDA data]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
If you take this product, be mindful of your total calcium intake from all sources. Do not exceed the recommended daily allowance without consulting your doctor, especially if you take medications for osteoporosis, thyroid conditions, or infections [NIH ODS].
