In short:
- Vitamin D deficiency affects most people aged 60+, and adequate intake reduces fracture risk and supports muscle function.
- Vitamin B12 absorption declines significantly with age, so up to 40% of older adults need supplementation.
- Omega-3 fatty acids and adequate protein intake help slow sarcopenia and support cardiovascular health.
- Talk to your doctor before you start taking supplements, especially if you use medication – interactions are real.
Supplements for older adults are a topic that doctors and nutrition scientists are paying more and more attention to: with age, nutrient needs change, absorption declines, and certain deficiencies can significantly affect quality of life. In this evidence-based overview, we explain which supplements are best justified at 60+ and how to use them safely.
Which supplements for older adults are best supported by science?
Supplements for older adults don’t mean a universal handful of pills – it is a targeted approach based on the physiological changes that come with age. According to the NIH Office of Dietary Supplements (ODS), the nutrients that need the most attention at 60+ are vitamin D, vitamin B12, calcium, magnesium and omega-3 fatty acids.
There are many common myths and a lot of confusion around supplements. We recommend our overview article Questions and answers: Supplements, which covers the most frequently asked questions. Supplements complement – but do not replace – a varied diet, and the article SUPPLEMENTS: whether, when, how much will help you understand when and why supplements become necessary at all.
Why does vitamin D need special attention at 60+?
Vitamin D deficiency is one of the most common nutrient deficiencies among older adults worldwide. As we age, the skin synthesizes less and less vitamin D from sunlight, and the kidneys’ ability to convert the vitamin into its active form declines as well (Holick, 2007). Studies show that adequate vitamin D intake reduces the risk of non-vertebral fractures by up to 20%, according to meta-analysis data (Bischoff-Ferrari et al., 2005).
EFSA recognizes health claims for vitamin D related to normal muscle function, the maintenance of bones and support of the immune system (EFSA, 2012). In Estonia, it is advisable to supplement vitamin D intake during the winter months – 10–20 μg a day for adults, and up to 20 μg for older adults. Combining calcium and vitamin D is critical for maintaining bone density, because calcium absorption depends directly on adequate vitamin D levels in the blood.
How does vitamin B12 deficiency affect the health of older adults?
Vitamin B12 absorption declines significantly after age 60, because the production of stomach acid and intrinsic factor falls. Andres et al. (2004) found that up to 40% of older adults suffer from B12 deficiency or borderline levels. B12 deficiency can show up as fatigue, mood disturbances, cognitive decline and peripheral nerve damage.
Unlike B12 from food, free-form B12 taken as a supplement (cyanocobalamin or methylcobalamin) is absorbed more effectively even by people whose digestive glands are not working optimally. Sublingual tablets are therefore often the preferred choice for older adults.
How do supplements help preserve muscle mass after age 60?
Sarcopenia – age-related loss of muscle mass – begins as early as your 40s, but accelerates markedly after age 60. According to the revised European consensus by Cruz-Jentoft et al. (2019), sarcopenia is associated with an increased risk of falls and reduced quality of life.
Adequate protein intake (1.2–1.6 g per kilogram of body weight per day) combined with endurance training is the cornerstone of preserving muscle mass. Why training is just as important for older adults as nutrition is explained in the articles Why strength training is vital for older adults and Supplements for athletes.
Omega-3 fatty acids – especially EPA and DHA – have shown a positive effect on muscle protein synthesis in older adults. Smith et al. (2011) found that omega-3 supplementation increased the rate of muscle protein synthesis statistically significantly compared with placebo. Creatine monohydrate is another supplement with a proven benefit, when combined with training, for preserving muscle strength and mass in older age groups.
Which supplements should older adults use with caution?
Not all supplements suit everyone, or every medication. Calcium in large doses may increase the risk of kidney stones, and some studies point to a possible cardiovascular risk with overdosing. Magnesium in large doses can cause gastrointestinal symptoms through its laxative effect.
Patients who use anticoagulants should be especially careful with omega-3 and vitamin K intake and consult their doctor before starting supplements. When planning nutrition and supplements for older adults, the WHO advises always taking individual health risks and medication interactions into account.

Frequently asked questions
Which supplements do most people aged 60+ need?
According to the scientific literature, the most common deficiencies in older adults are in vitamin D, vitamin B12 and magnesium. Supplementing vitamin D and B12 is justified in many cases even without a prior blood test, but it’s worth getting one done to determine the exact dose.
How much vitamin D should people aged 60+ take per day?
In Estonia, adults are advised to get 10–20 μg (400–800 IU) of vitamin D per day, and older adults up to 20 μg. In the winter months or with certain health conditions, a doctor may recommend higher doses, but more than 100 μg per day is not recommended without medical supervision.
Do older adults get enough vitamin B12 from food?
Because gastric juice production declines with age, older adults absorb B12 from food less well. Free B12 taken as a supplement is absorbed even when the digestive glands aren’t working at full capacity. That is why older adults are often advised to take B12 as a supplement, preferably in sublingual form.
Can older adults who don’t train intensively use creatine?
Studies of creatine monohydrate in older adults have shown benefits for supporting muscle strength and functional capacity even with moderate training. Creatine is considered well tolerated in terms of its safety profile, but if you have kidney problems, talk to your doctor before starting.
Are omega-3 supplements safe to take with blood thinners?
High doses of omega-3 (over 3 g per day) can enhance the effect of blood thinners such as warfarin. If you take anticoagulants, be sure to consult your doctor before starting omega-3 supplements.
