Most seniors are eating far too little protein — and the consequences show up as muscle loss, fatigue, and slower recovery from illness. But protein isn’t the only nutrient to watch after 60. Here are the five that matter most, what the research says about how much you actually need, and easy ways to get there.
Eating well after 60 is different from eating well at 40. Your body absorbs certain nutrients less efficiently, your calorie needs drop while your nutrient needs stay the same or increase, and the consequences of deficiency compound faster. Understanding which nutrients to prioritise — and why — is one of the most practical things you can do for your long-term health.
1. Protein: You Probably Need More Than You Think
The standard recommendation of 0.8g of protein per kilogram of body weight was set for young adults. Research over the past decade has consistently shown that adults over 60 need significantly more — roughly 1.2 to 1.6g per kilogram — to maintain muscle mass, support immune function, and recover from illness or injury.
This matters because muscle loss (sarcopenia) accelerates after 60, contributing to falls, weakness, and loss of independence. Protein is the primary dietary tool to slow it down.
For a 70kg (154 lb) person, that’s 84–112g of protein daily. Most seniors eat 50–60g. Practical sources: 3 eggs (18g), 100g chicken breast (31g), 200g Greek yogurt (20g), 1 can tuna (25g). Spread intake across meals — your muscles can only use about 25–30g at a time effectively.
A 2022 meta-analysis in Nutrients found that seniors eating ≥1.2g/kg protein had significantly better muscle mass preservation and lower fall risk than those meeting only the standard 0.8g/kg recommendation.
2. Vitamin D: Almost Every Senior Is Low
Vitamin D deficiency affects an estimated 40–60% of adults over 65 in the US, and many more are insufficient rather than outright deficient. After 60, your skin produces vitamin D from sunlight at roughly one-quarter the efficiency it did at 20. And if you live above the 37th parallel (north of Atlanta), sunlight is too weak to produce vitamin D for much of the year regardless of age.
Low vitamin D is linked to bone loss, muscle weakness, increased fall risk, impaired immune function, and depression. Getting a blood test (25-OH vitamin D) is the only way to know where you stand.
The Endocrine Society recommends 1,500–2,000 IU daily for adults over 60. Take D3 (cholecalciferol) rather than D2 — it’s more effective at raising blood levels. Take with a meal containing fat for best absorption. Optimal blood level: 40–60 ng/mL.
3. Calcium: The Bone Health Baseline
After menopause, women lose bone density rapidly as estrogen levels fall. Men also lose bone mass after 70. Calcium is the foundational building block — but the research on supplementation is more nuanced than once thought.
Food sources of calcium are preferable to supplements where possible: the evidence for fracture reduction from food calcium is stronger, and high-dose calcium supplements (>1,000mg/day from supplements alone) have been linked to increased cardiovascular risk in some studies.
Best food sources: dairy (300mg per serving), fortified plant milks, sardines with bones (325mg per can), kale, and almonds. If supplementing, don’t take more than 500mg at once — that’s the maximum the intestine can absorb in a single dose. Calcium carbonate requires stomach acid (take with food); calcium citrate can be taken any time and suits those on acid-reducing medications.
Calcium and vitamin D work together. Without adequate vitamin D, your intestine can only absorb about 10–15% of dietary calcium. Getting both right is essential.
4. Vitamin B12: The Silent Deficiency
Vitamin B12 deficiency is one of the most under-diagnosed problems in older adults. Up to 20% of seniors are deficient, and the symptoms — fatigue, brain fog, balance problems, tingling in hands and feet — are easy to attribute to “just getting older.” Left untreated, B12 deficiency causes irreversible nerve damage.
The problem isn’t usually diet — it’s absorption. B12 from food is bound to protein and must be freed by stomach acid. With age, many people produce less stomach acid (a condition called atrophic gastritis), which dramatically reduces B12 absorption from food. Metformin (for diabetes) and acid-reducing medications (PPIs, H2 blockers) also deplete B12.
Supplemental B12 doesn’t require stomach acid for absorption, which is why supplements work even when food B12 doesn’t. Sublingual (under the tongue) tablets are particularly well absorbed. Look for methylcobalamin or cyanocobalamin forms — both are effective. If your levels are very low, your doctor may recommend B12 injections initially.
5. Omega-3 Fatty Acids: Brain and Joint Protection
Omega-3s (EPA and DHA from fish oil) have two particularly strong evidence bases for seniors: reducing inflammatory joint pain and supporting cognitive function. A 2022 study in JAMA Network Open found that omega-3 supplementation reduced the risk of cognitive decline in older adults by 13% over five years.
Most people over 60 are chronically low in omega-3s, especially if they eat little fatty fish. The ratio of omega-6 to omega-3 in the typical Western diet (roughly 15:1) drives systemic inflammation — a major contributor to arthritis, cardiovascular disease, and accelerated brain aging.
Best food sources: salmon (1,800mg per 3oz serving), mackerel, sardines, anchovies. If supplementing, look for the combined EPA+DHA total on the label — not just the total fish oil amount (a 1,000mg capsule often contains only 300mg of actual EPA+DHA). Take with a fatty meal to reduce fishy burps. Algae-based omega-3s are an effective plant-based alternative.
How to Actually Hit These Targets
Tracking five separate nutrients sounds overwhelming. In practice, a few daily habits cover most of the bases:
- Morning: Greek yogurt (protein + calcium) + a D3/B12 supplement with breakfast
- Lunch: A palm-sized portion of protein (chicken, tuna, eggs, legumes)
- Dinner: Fatty fish 2–3x per week; meat or eggs on other nights
- Supplement shortlist: Vitamin D3 (1,000–2,000 IU), B12 (500mcg), and omega-3 (1,000mg EPA+DHA) cover the three nutrients hardest to get from diet alone after 60
Get a blood test for vitamin D and B12 first — both are standard and inexpensive. If you’re deficient in either, supplementing will make a noticeable difference within 6–8 weeks. Then focus on hitting your protein target each day. The rest follows naturally.
