Our assessment
The evidence shows that RejuviCare Super Collagen’s key ingredient, calcium, plays a well-established role in bone health. However, for a general audience seeking evidence-based information, we must be clear: the data provided does not include specific studies or clinical trials on this exact product. The core benefit of calcium is its support for bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a structural building block for your bones. It works by supporting bone density and the deposition of minerals into your skeleton, which is critical for maintaining strength as you age. Additionally, it plays a key role in helping your muscles relax and your nerves signal properly after contraction [NIH ODS].
Safety profile
The FDA has received 592,059 total adverse event reports for products in this category. Specific side effects for calcium can occur, especially at high intakes. You may experience constipation, nausea, weight loss, extreme tiredness, or a frequent need to urinate. Very high levels of calcium in the blood can lead to poor muscle tone, abnormal heart rhythms, and a high risk of death from heart disease [FDA data] [NIH ODS]. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
For most adults, data on the optimal calcium intake for this specific product is not available. Because calcium can interfere with medications like bisphosphonates, tetracycline antibiotics, and levothyroxine, you should take this supplement at a different time than those drugs [NIH ODS]. We recommend you consult your healthcare provider before starting, especially if you have a history of kidney stones or heart conditions. Data not available for specific dosing for this product.
