GNC Preventive Nutrition Bone & Joint Health Formula
Brand: GNC Preventive Nutrition · Form: SUPPLEMENT FORM, OTHER [E0172] On Market
Our assessment
The evidence shows that GNC Preventive Nutrition Bone & Joint Health Formula contains calcium, a mineral essential for bone health. Based on the data provided, this product may support bone density, but the overall evidence is focused solely on the calcium ingredient. Data is not available for other ingredients in this formula.
How it works
Calcium supports your body through bone mineralization, helping to maintain bone density and mineral deposition. It also plays a role in neuromuscular relaxation, which aids muscle relaxation and nerve signaling [NIH ODS]. Think of it as a key building block for your skeletal structure.
Safety profile
FDA received 592,059 total adverse event reports across all products in the database, though specific numbers for this formula are not available. For calcium, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. High levels in the 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]. Calcium can also reduce the absorption of medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
If you choose this product, be aware of its calcium content and potential interactions with medications. Do not exceed the recommended daily intake of calcium without medical supervision. Consult your healthcare provider before starting, especially if you take prescription medications or have a history of kidney issues or heart disease [NIH ODS].
