Nature's Bounty Optimal Solutions Advanced Collagen

Our assessment

The evidence shows that this product contains calcium, a mineral essential for bone health. However, you should understand both its benefits and its risks before taking it. The data indicates that calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. We recommend you evaluate your dietary calcium intake first, as many people get enough from food.

How it works

Think of calcium as a structural building block for your bones and a key signaling molecule for your muscles and nerves. It helps deposit minerals into your bone matrix to maintain density and supports muscle relaxation and proper nerve signaling throughout your body [NIH ODS].

Safety profile

FDA received 592059 total adverse event reports across all supplements. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels 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 several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

You should only take this supplement if your diet is low in calcium. Start with a low dose and be aware of the potential for constipation and nausea [NIH ODS]. If you take any prescription medications, especially thyroid medication or antibiotics, take calcium at a different time of day to avoid absorption issues [NIH ODS]. Data on the specific collagen ingredients in this product is not available, so we cannot evaluate their effectiveness.
