Brand: Jarrow Formulas · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Jarrow Formulas Type II Bioavailable Collagen Complex contains calcium as an ingredient. Our assessment is that this supplement may support bone health through calcium’s role in bone mineralization, but you should be aware of specific safety considerations before using it [NIH ODS]. Data on the collagen components of this product is not available from the provided data.
How it works
Think of calcium as a key structural component for your bones. It supports bone density and mineral deposition, and it also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. While collagen is often taken for joint and skin support, the provided data does not include any mechanism or study details for collagen specifically.
Safety profile
FDA received a total of 592059 adverse event reports across all supplement categories. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for specific dosing or studies on this collagen complex. If you are taking any medications on the interaction list, separate calcium intake by at least two hours. Start with a moderate calcium intake from food sources first, and consult your doctor before adding this supplement, especially if you have a history of kidney stones, heart disease, or prostate concerns [NIH ODS].
