From the Research
Collagen supplements are not recommended for skin, joint, or general health benefits due to a lack of clinical evidence supporting their effectiveness, as shown in the most recent and highest quality study 1. When considering the use of collagen supplements, it's essential to prioritize the outcome of morbidity, mortality, and quality of life. The current evidence suggests that collagen supplements may not provide significant benefits for skin aging, and their effects on joint health are still unclear. Some key points to consider:
- The quality of the evidence is a crucial factor in determining the effectiveness of collagen supplements, and high-quality studies have shown no significant effects on skin hydration, elasticity, and wrinkles 1.
- The funding source of the studies may influence the outcomes, and studies not receiving funding from pharmaceutical companies have revealed no effect of collagen supplements on skin aging 1.
- While some studies suggest that collagen supplements may improve skin elasticity and hydration, these findings are not consistent across all studies, and more research is needed to establish the efficacy of collagen supplements 2, 3.
- Collagen supplements are generally considered safe, but individuals with certain medical conditions or allergies should consult a healthcare provider before starting supplementation 4, 5.
- The optimal dosage and duration of collagen supplementation are still unclear, and more research is needed to determine the most effective regimen 5.
