Do Fiber Supplements Support Healthy Aging Pathways?

Do fiber supplements support healthy aging pathways? Only indirectly: fiber lowers LDL cholesterol and blood sugar and feeds gut bacteria linked to lower frailty in older adults, but no trial shows it slows cellular aging. Pair a fiber supplement with a Mediterranean-style diet, and skip high-dose antioxidant pills sold as anti-aging.

Are Fiber Supplements Effective for Healthy Aging?

Are fiber supplements effective for healthy aging? They help with specific problems that grow more common with age, such as constipation and high LDL cholesterol, but the long-life link in large studies comes mostly from fiber in whole grains, not from supplements. If you add psyllium, mix each dose into at least 8 ounces of liquid, keep it 3 hours away from digoxin, aspirin and nitrofurantoin, and check with your doctor first if you have swallowing problems.
