3. Collagen
As you age, the production of collagen — a protein that helps maintain skin structure — slows, leading to accelerated signs of aging like wrinkles.
Some research suggests that supplementing with collagen may reduce signs of aging, including wrinkles and dry skin.
For example, a 12-week study in 72 women demonstrated that taking a supplement that contained 2.5 grams of collagen — along with several other ingredients, including biotin — per day significantly improved skin hydration, roughness, and elasticity.
Other human studies show that collagen supplements may improve skin elasticity, reduce wrinkles, increase skin hydration, and improve nail growth.
Though these results are promising, many of these studies are funded by companies that manufacture collagen products, which may influence study results.
Many types of collagen supplements are available, including powders and capsules.
SUMMARYCollagen is a popular dietary supplement that may help prevent skin aging by boosting collagen levels in your skin.
4. CoQ10
Coenzyme Q10 (CoQ10) is an antioxidant that your body produces. It plays an essential role in energy production and protects against cellular damage.
Research suggests that levels of CoQ10 decline as you age. Supplementing with it has been shown to improve certain aspects of health in older individuals.
For instance, a 4-year study in 443 older adults demonstrated that supplementing with CoQ10 and selenium improved overall quality of life, reduced hospital visits, and slowed physical and mental deterioration.
CoQ10 supplements may work by reducing oxidative stress, a condition characterized by an accumulation of free radicals that accelerates the aging process and the onset of age-related disease.
Additionally, CoQ10 supplements may benefit heart health by reducing stiffness in your arteries, lowering blood pressure, and preventing the buildup of oxidized cholesterol in your arteries.
SUMMARYCoQ10 is an antioxidant that your body naturally produces. Supplementing with it may slow age-related physical decline and improve quality of life in older adults.
