Key Takeaways
- Research cited from The American Journal of Medicine indicates non-industry funded studies showed no clear skin benefits from collagen supplements.
- Vitamin D3 and K2 support bone health, but experts recommend checking blood levels first to see if supplementation is actually needed.
- Magnesium glycinate is used by some to assist with sleep, though medical experts note that current evidence remains limited.
What the Source Says
Dr. Debra Jaliman, a clinical assistant professor at the Icahn School of Medicine at Mount Sinai, discussed her personal approach to healthy aging. While collagen is widely advertised, research suggests independent studies showed no effect on skin hydration, elasticity, or wrinkles. Instead, her routine prioritizes individual biological needs confirmed by blood work.
For bone health, vitamin D helps absorb calcium, while vitamin K activates proteins involved in bone metabolism. Dr. Jaliman suggests obtaining a baseline blood test before taking vitamin D. Research suggests that routine supplementation may not benefit everyone; Dr. Luke Sorrell, a longevity physician, noted that the large VITAL trial found daily vitamin D did not lower fracture risks in adults who were not deficient. However, surveys show that insufficient or low levels remain common among adults aged 50 to 79.
Dr. Jaliman also takes magnesium glycinate in the evening for sleep support. The National Institute on Aging reports that poor sleep in older adults can negatively impact memory and mood while increasing fall risks. Research suggests magnesium may modestly reduce the time it takes to fall asleep, though trial evidence is considered low to very low quality by reviewers.
Practical Notes
Dietary supplements are not one-size-fits-all and require careful consideration regarding safety and potential medication interactions. For instance, changes in vitamin K intake can alter how blood thinners like warfarin function. High doses of supplemental magnesium above 350 mg may cause digestive issues such as diarrhea, and individuals with kidney disease or kidney stones require special medical guidance before taking these products.
