Jarrow Formulas Type II Bioavailable Collagen Complex
Brand: Jarrow Formulas · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Jarrow Formulas Type II Bioavailable Collagen Complex contains calcium, a mineral essential for bone health. Data on the specific collagen complex itself is limited, so we must focus on the calcium component. For calcium, the data supports its role in bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should be aware that high intakes may carry risks, and the specific benefits of this product's collagen formulation are not detailed in the provided data.
How it works
Think of calcium as a key structural component for your bones. It supports bone density by aiding mineral deposition and also plays a role in muscle relaxation and nerve signaling [NIH ODS]. The "Type II Bioavailable Collagen Complex" label suggests it is designed for absorption, but the provided data does not include specific studies or mechanisms for collagen itself from this product.
Safety profile
Total adverse event reports across all products in the FDA database are 592,059 [FDA data]. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High blood and urine levels can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Given the lack of specific data on this collagen complex, we recommend you rely on established calcium guidelines. For bone health, ensure you meet your calcium needs from food first. If you choose this supplement, be cautious of total calcium intake from all sources to avoid exceeding safe levels. Always consult your doctor before starting, especially if you take medications that interact with calcium [NIH ODS].
