Our assessment
The evidence shows that this product combines two popular joint-support ingredients, but you need to be aware of the specific risks tied to the calcium content. Our assessment: this supplement may support joint comfort, but the calcium component requires careful attention to your total daily intake and any medications you take [NIH ODS].
How it works
Think of the hydrolyzed collagen as a building block that provides amino acids your body uses to support connective tissue, while hyaluronic acid acts as a cushion in your joints. However, the key active mineral here is calcium, which supports bone mineralization and neuromuscular relaxation [NIH ODS]. You need calcium for strong bones, but getting it from a supplement means you must account for all other sources in your diet and any other supplements you take [NIH ODS].
Safety profile
Data not available for side effects specific to this product. However, the FDA has received a total of 592,059 adverse event reports across all dietary supplements. The calcium in this formula carries important risks: high calcium intakes might increase the risk of heart disease and prostate cancer, and high levels in your blood can cause poor muscle tone, poor kidney function, 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 several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
If you are considering this product, first check your total daily calcium intake from all sources — food, other supplements, and this product combined — to keep it within safe limits [NIH ODS]. Be especially cautious if you take any of the medications listed above, as you should separate your calcium dose by at least two hours [NIH ODS]. For most people, getting calcium from food is safer and more effective than from supplements [NIH ODS]. Our recommendation: consult your healthcare provider to review your total calcium intake and medication list before starting this product.
