Life Extension Hair, Skin & Nails Collagen Plus Formula
Brand: Life Extension · Form: TABLET [E0155]
Our assessment
The evidence shows that this product contains calcium, which supports bone density and neuromuscular relaxation [NIH ODS]. However, based on the data provided, we cannot make a specific assessment of the "Hair, Skin & Nails Collagen Plus Formula" as a whole, as the only ingredient data available is for calcium. For a complete picture, you would need to look at the full label of this specific product.
How it works
Calcium plays a key role in bone mineralization, helping to deposit minerals into your bone structure for strength [NIH ODS]. It also supports neuromuscular relaxation, which is essential for proper muscle function and nerve signaling [NIH ODS]. These mechanisms are foundational for overall health but do not directly address hair, skin, or nail growth based on the data provided.
Safety profile
The FDA has received a total of 592,059 adverse event reports for all dietary supplements in their database [FDA data]. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. High blood or urine calcium levels can cause poor muscle tone, kidney dysfunction, 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 medications like bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available on side effects or report counts specific to this product.
Our recommendation
You should review the full label of Life Extension Hair, Skin & Nails Collagen Plus Formula to see all ingredients and their amounts. If you are taking medications such as antibiotics or thyroid medication, be aware that calcium can interfere with their absorption [NIH ODS]. Because data on the product's collagen and other ingredients is not available in this analysis, you should consult your healthcare provider before starting this supplement to ensure it is safe and appropriate for your needs.
