Our assessment
The evidence shows that this product’s primary active ingredient, calcium, is well-supported for bone health. However, the specific “Collagen + C” formula from Spring Valley is not directly addressed in the data provided. Our assessment is that the calcium component offers clear benefits, but you should be aware of the specific risks and interactions detailed below.
How it works
Think of calcium as a structural foundation for your skeleton. It supports bone mineralization and bone density, and it also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports for all products in its database. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine levels can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS].
Our recommendation
Because the data for the collagen and vitamin C components is not available, we cannot make a full recommendation for this specific product. For the calcium component, you should be cautious with dosing and be aware that calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Consult your healthcare provider before starting this supplement, especially if you take any of these medications.
