Our assessment
Our assessment: The evidence shows that this product contains calcium, a mineral essential for bone health and nerve function. However, the data does not provide specific details about the collagen ingredient itself, and we must base our analysis solely on the calcium content provided [NIH ODS]. You should be aware that the benefits of calcium depend on your current intake from food and supplements.
How it works
Calcium acts as a master regulator for your bones through bone mineralization, supporting bone density and mineral deposition. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received 592,059 adverse event reports across all supplements. For calcium specifically, the data indicates that high intakes might increase the risk of heart disease and prostate cancer. 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 several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available for side effects specific to the collagen ingredient.
Our recommendation
Our recommendation: Since data on the collagen content is not available, focus on your total calcium intake from all sources. Do not exceed 2,000 mg of calcium per day from supplements and food combined, as high intakes carry serious risks [NIH ODS]. Take calcium supplements with food and separate from thyroid medication or antibiotics by at least two hours [NIH ODS]. Consult your doctor before starting this supplement, especially if you have kidney issues or heart disease.
