Our assessment
The evidence shows that Puritan's Pride Hydrolyzed Collagen provides calcium as a key ingredient. Our assessment is that calcium is essential for bone health, but the specific benefits of collagen for skin or joints are not supported by the data provided. You should focus on the calcium content for bone mineralization [NIH ODS].
How it works
Think of calcium as a structural builder — it supports bone density and mineral deposition, which is critical for maintaining strong bones. It also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports for products in this category. Specific side effects for calcium include a risk of constipation, nausea, and abnormal heart rhythms at high levels. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [FDA data] [NIH ODS].
Our recommendation
Data not available for specific dosing. You should be aware that calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine. Take this supplement at a different time than these medications [NIH ODS].
