Life Extension Bone Strength Collagen Formula
Brand: Life Extension · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health. Calcium is well-known for supporting bone density and mineral deposition [NIH ODS]. However, you should be aware that the data on calcium is mixed; some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a key building block for your skeleton. It supports bone mineralization, which is the process of depositing minerals into your bone matrix to keep them strong [NIH ODS]. Additionally, calcium plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports for this product category [FDA data]. Specific side effects from high calcium levels include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [NIH ODS]. High levels in the blood and urine can also cause poor muscle tone, poor kidney function, and a high risk of death from heart disease [NIH ODS]. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
If you are considering this supplement, you should be aware of the potential risks from high calcium intake. Do not exceed the recommended dosage. If you take any of the medications listed above, separate your calcium dose by at least two hours to avoid absorption issues [NIH ODS]. As always, consult your healthcare provider before starting any new supplement, especially if you have a history of kidney problems or heart disease [NIH ODS].
