Sanar Naturals Collagen

Our assessment

The evidence shows that Sanar Naturals Collagen contains calcium, a mineral essential for bone health. Based on the data provided, our assessment is that this product can support your bone density and muscle function, but you must be careful with dosage and potential interactions. The total number of adverse event reports across all supplements in the FDA database is 592,059, though specific reports for this product are not isolated in the data [FDA data].

How it works

Think of calcium as a structural builder for your skeleton. It supports bone mineralization and density, helping keep your bones strong as you age. Calcium also plays a key role in neuromuscular relaxation, which helps your muscles and nerves signal properly [NIH ODS].

Safety profile

Safety data from the NIH ODS indicates that high calcium intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in your 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Data not available on the specific dosage of calcium in Sanar Naturals Collagen, so you should check the label carefully. If you take any medications, especially those listed above, take this supplement at least two hours apart from them to avoid absorption issues [NIH ODS]. We recommend you speak with your healthcare provider before starting this product to ensure your total calcium intake from food and supplements stays within safe limits.
