Latest Trends in Natural Supplements for Healthy Aging | Kasivit

Aging is a journey everyone goes through, and many are looking for ways to age gracefully and healthily. Healthy aging has become a prominent topic as more individuals seek effective ways to maintain their vitality, cognitive function, and overall well-being as they age. Many people take supplements as they age: in one US national survey, about half of adults reported using at least one dietary supplement in the previous 30 days¹. However, we are not aware of good evidence that any supplement slows human aging, and large reviews have found insufficient evidence, or no benefit, for most supplements in preventing heart disease or cancer^1,2. This article looks at what is known and what to watch out for. Let’s explore the latest trends in natural supplements specifically designed to support healthy aging, alongside some highly recommended products.

Understanding Healthy Aging

Healthy aging means more than just living longer. It’s about maintaining a good quality of life and independence, staying active, and keeping both physical and mental health in check. A balanced diet and regular exercise are key. Supplements may help fill specific nutritional gaps for some people, but they are not a substitute for these basics.

Safety First: Talk to Your Doctor or Pharmacist

Supplements can interact with prescription medicines and can cause side effects, even when they are "natural". Tell your doctor or pharmacist about every supplement you take, and check with them before adding a new one, especially if you take prescription medicines, have liver disease, kidney disease, diabetes or a bleeding condition, or are pregnant. Some examples:

• Turmeric (curcumin). Liver injury has been reported with turmeric supplements. In a US case series of 10 people, 5 were hospitalized and 1 died of acute liver failure; injury typically appeared 1 to 4 months after starting, and some of the products also contained black pepper extract (piperine)³. A 2026 review by the United States Pharmacopeia (USP) described liver problems as very rare and recommended that people with a history of liver problems consult a health-care practitioner before use⁴.
• Green tea extract. Concentrated extracts have been linked to liver injury; published case reports involve catechin (EGCG) intakes from about 140 mg to about 1,000 mg a day. USP label advice is to take it with food rather than on an empty stomach, and not to use it if you have a liver problem⁵. For both turmeric and green tea extract, stop the product and seek medical advice if you develop abdominal pain, dark urine, or yellowing of the skin or eyes^4,5.
• Omega-3 fish oil. A review of 11 randomized trials found no overall increase in bleeding with omega-3, although high-dose purified EPA was linked to a modest increase⁶. If you take a blood thinner or have a bleeding disorder, ask your doctor or pharmacist first. Marine omega-3 supplements have also been associated with a higher risk of atrial fibrillation (an irregular heartbeat), with a larger increase in trials testing more than 1 g a day⁷.
• Ginkgo. Case reports have linked ginkgo to bleeding⁸, although controlled studies have not shown a significant effect on blood clotting or on the safety of aspirin or warfarin⁹. If you take blood thinners or have a bleeding risk, ask your doctor or pharmacist before using ginkgo.
• CoQ10. A case report described a reduced response to warfarin in a woman who took CoQ10¹⁰. In a meta-analysis, CoQ10 lowered systolic blood pressure by about 3 mmHg on average¹¹, and in people with metabolic disorders it lowered blood glucose¹². If you take warfarin, blood pressure medicines or diabetes medicines, ask your doctor or pharmacist first.
• Vitamin K2. In a study of volunteers taking the anticoagulant acenocoumarol, vitamin K2 (MK-7) at doses as low as 10 mcg a day changed blood-clotting tests in some people, and the authors advised that MK-7 supplements be avoided by people on vitamin K antagonist therapy such as warfarin¹³. See our vitamin D3 and K2 article.
• Alpha-lipoic acid. It has rarely been linked to insulin autoimmune syndrome, a rare cause of recurrent low blood sugar¹⁴. Tell your doctor if you take it and have diabetes or repeated low blood sugar.
• Vitamin E. A meta-analysis of trials linked vitamin E at 400 IU a day or more to a higher risk of death from any cause¹⁵, and the US Preventive Services Task Force recommends against vitamin E supplements for preventing cardiovascular disease or cancer¹.

This list is not complete, and it is not a reason to stop or change any prescribed medicine. If you notice new symptoms after starting a supplement, contact your doctor or pharmacist.

Supplements Commonly Used for Healthy Aging

When choosing a supplement, look for quality and clear ingredient lists, and talk to your doctor or pharmacist. Some commonly used supplements include:

• Omega-3 fatty acids. Omega-3s are found in oily fish. In a Cochrane review of 86 trials (mostly of omega-3 capsules), increasing omega-3 intake had little or no effect on all-cause deaths or cardiovascular events¹⁶, and higher doses have been associated with more atrial fibrillation⁷.
• CoQ10. CoQ10 plays a major role in energy production inside cells. It can interact with some medicines, including warfarin; see the safety section above¹⁰.
• Resveratrol, found in red wine and grapes, has antioxidant effects in laboratory studies. In a small 90-day trial of 32 older adults, 300 mg and 1,000 mg a day did not increase adverse events¹⁷, but supplemental doses of about 1 g a day or more may interact with some medicines¹⁸. Whether resveratrol improves health in older adults has not been established.

Selecting quality supplements means buying from trusted brands that use pure, effective ingredients. It's important to check for third-party testing and clear ingredient lists when making a choice.

Natural Supplements Often Marketed for Aging

Natural supplements are popular because they often come from plants, but natural does not mean risk-free. Some commonly used examples include turmeric, green tea extract, and ginseng. These have anti-inflammatory and antioxidant effects in laboratory studies; benefits for healthy aging in people have not been proven.

Some natural supplements have been studied for their effects in older adults, with mixed results. For example, turmeric contains curcumin, which has anti-inflammatory effects in laboratory studies. Liver injury has been reported with turmeric supplements (see the safety section above)^3,4. Green tea extract is rich in catechins such as EGCG. Concentrated extracts have been linked to liver injury, and the extract should be taken with food rather than on an empty stomach⁵. Whether these supplements slow aging or improve overall health in people has not been proven.

Vitamins for Healthy Aging

Certain vitamins are essential for healthy aging. Vitamin D helps maintain bone strength¹⁹. Vitamin B12 is crucial for nerve health and energy production. Vitamins C and E act as antioxidants in the body, but supplements have not been shown to prevent heart disease or cancer, and vitamin E at 400 IU a day or more has been linked to a higher risk of death from any cause in a meta-analysis of trials^1,2,15.

Older adults may need more of some nutrients. For example, the recommended daily vitamin D intake rises from 600 IU to 800 IU from age 71¹⁹. Ask your doctor before taking more than the recommended amounts. Vitamin B12 supplements may be necessary when dietary intake is low, especially for those on limited diets.

Foods rich in these vitamins include fatty fish, leafy greens, eggs, and fortified cereals. Supplements may help fill gaps when the diet falls short, but they do not replace a varied diet.

Supplements for Cellular Health

Cellular health is the backbone of healthy aging. Cells constantly regenerate, so supporting this process is vital. Some supplements affect cellular processes in laboratory studies, but we are not aware of evidence that any of them slows aging in people.

Nicotinamide riboside (NR) and alpha-lipoic acid are two supplements gaining attention for their role in cellular health. NR boosts levels of NAD+, a molecule important for energy metabolism and cell repair. Alpha-lipoic acid acts as an antioxidant. It has rarely been linked to insulin autoimmune syndrome, a rare cause of recurrent low blood sugar¹⁴; tell your doctor if you take it and have diabetes or repeated low blood sugar.

In an 8-week, manufacturer-funded trial in overweight adults, nicotinamide riboside raised blood NAD+ levels without more adverse events than placebo²⁰. Whether this improves health or slows aging in older adults has not been shown, and the trial lasted only 8 weeks.

Supplements for Brain Health

A healthy brain is key to aging well. Brain health impacts memory, focus, and overall cognitive function. Some supplements are marketed for brain health, but large trials of omega-3 and ginkgo have not shown that they prevent dementia or cognitive decline^21,22.

Popular supplements for brain health include omega-3s, phosphatidylserine, and ginkgo biloba. In a review of 38 randomized trials, long-chain omega-3 supplements had little or no effect on new dementia or cognitive impairment²¹. Phosphatidylserine helps maintain the structure and fluidity of brain cell membranes. Ginkgo biloba is widely used for memory, but in a large trial of 3,069 adults aged 75 or older it did not reduce the rate of dementia²². Case reports have linked ginkgo to bleeding, so check with your doctor or pharmacist if you take blood thinners⁸.

Staying physically active, socially connected and mentally engaged are other ways people try to support brain health. Talk to your doctor or pharmacist before taking supplements for memory.

Collagen Supplements for Skin

Collagen is a key protein that keeps skin firm and youthful. As we age, collagen production decreases, leading to wrinkles and sagging skin. Some people take collagen supplements hoping to support skin health.

Collagen supplements, often available as powders or capsules, provide the amino acids needed for the body to build new collagen. A 2026 meta-analysis of 19 randomized trials of oral and topical peptides (not collagen alone) found improved skin hydration and brightness and a modest reduction in wrinkles, with inconsistent effects on elasticity²³.

Adding collagen to your daily routine along with a healthy diet and sun protection may support skin appearance.

Conclusion

Many people use supplements as they age, but they work best alongside a balanced diet, regular physical activity and regular check-ups. Evidence varies widely between supplements, and some carry real risks or can interact with medicines, as described in the safety section above. Vitamins and minerals can help fill specific gaps in older adults when the diet falls short.
