Our assessment
The evidence shows that the active ingredient in this product, calcium, plays a well-documented role in supporting bone health. However, we need to be clear: this product is labeled as a free-form amino acid supplement, and the data we have is for calcium as a mineral. Based on the available information, calcium supports bone density and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a structural building block for your bones and a messenger for your nerves. It helps deposit minerals into your skeleton to maintain bone density, and it supports muscle relaxation and nerve signaling throughout your body [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine levels of calcium 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]. Calcium can also reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available on the specific dosage of calcium in this product. Because this is a free-form amino acid supplement, the calcium content is not listed in the provided data. For general bone health, you should not exceed the tolerable upper intake level of calcium without medical supervision. Always take calcium supplements separately from medications like thyroid hormone or antibiotics by at least 2 hours [NIH ODS]. Consult your healthcare provider before starting this product.
