Life Extension Hair, Skin & Nails Collagen Plus Formula
Brand: Life Extension · Form: TABLET [E0155] On Market
Our assessment
Our assessment is that this product contains calcium, a mineral essential for bone health, but it is not a complete solution for hair, skin, and nail support. The evidence shows that calcium's primary role is in bone mineralization and neuromuscular function, not directly in collagen synthesis for skin elasticity or hair growth [NIH ODS]. You should not rely on this formula as your sole source of collagen support.
How it works
Think of calcium as a structural foundation for your body. It supports bone density and mineral deposition, which is critical for your skeletal framework, and helps with muscle relaxation and nerve signaling [NIH ODS]. However, for improving the appearance of your hair, skin, and nails, calcium does not directly stimulate collagen production or provide the specific amino acids needed for those tissues. Data on the specific benefits of this combination for skin and nail health is not available.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements, though specific report counts for this exact product are not available. For calcium, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine calcium levels 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 bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation is to use this product only if you have a confirmed need for additional calcium, such as a low dietary intake or a healthcare provider’s advice. For targeted hair, skin, and nail support, you may benefit more from a dedicated collagen peptide or biotin supplement. Always take calcium supplements separately from other medications by at least two hours to avoid absorption interference [NIH ODS]. Start with a single serving daily and monitor for any digestive discomfort.
