Doctor's Best Collagen Types 1 & 3 Powder
Brand: Doctor's Best · Form: POWDER [E0162]
Our assessment
The evidence shows that Doctor's Best Collagen Types 1 & 3 Powder contains calcium, but data on the collagen itself is not provided. For the calcium component, we can offer guidance. The primary role of calcium is bone mineralization, supporting bone density and mineral deposition, as well as neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It works by depositing into bone tissue to maintain strength and density, and it also helps your muscles relax and nerves signal properly [NIH ODS].
Safety profile
Data not available for this specific product's side effects. However, for calcium, the FDA has received a total of 592,059 adverse event reports across all supplements. High calcium intakes might increase the risk of heart disease and prostate cancer. Very high levels can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent urination, and abnormal heart rhythms [NIH ODS].
Our recommendation
Since data on the collagen ingredients is not available, we cannot recommend this product for collagen-specific benefits. If you are taking this for calcium, be aware it can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. Start with a low dose and consult your doctor, especially if you take other medications.
