The four supplements worth considering after sixty

Most of what this site says about supplements is that you probably do not need them. After sixty, four of them earn a place, and for a specific reason.

It is not that ageing creates a general need for supplementation. It is that four particular things change with age in ways that diet alone handles poorly: absorption, synthesis, and the efficiency with which the body uses protein.

And a fifth point, which matters more than any of the four: what to stop. For most people over sixty, deprescribing produces more benefit than any addition.

This is information, not medical advice. Every one of these needs to fit with your existing medicines and conditions, particularly kidney disease. Take this article to your doctor rather than acting on it.

Why the usual answer is “test, don’t guess”

Before the four, the principle.

Taking a supplement for a deficiency you do not have produces nothing, and in two of the four below it produces harm. So the honest sequence is: test, correct, retest.

And the tests that are worth having after sixty:

Test	Why
Vitamin D (25-OH)	Synthesis falls with age; deficiency is common
Vitamin B12	Absorption falls with age; metformin and PPIs make it worse
Haemoglobin and ferritin	Anaemia after sixty needs a cause found, not just iron
TSH	Thyroid disease is common and presents vaguely
Creatinine and eGFR	Determines what is safe, especially calcium, magnesium and potassium
Calcium and albumin	Before and during calcium or vitamin D
HbA1c
Lipids and blood pressure

And one specific warning that applies to anyone on hair, skin or nail supplements: high-dose biotin interferes with many immunoassays, including thyroid and B12. Stop it before blood tests and tell the laboratory.

1. Vitamin D

The strongest case of the four.

Why age changes it

Three things happen together:

The skin’s capacity to synthesise vitamin D from UVB declines with age, the precursor concentration in skin falls.

Older adults spend less time outdoors, and often with more skin covered.

And the kidney’s conversion of vitamin D to its active form becomes less efficient where kidney function has declined.

In India, add pigmentation, pollution blocking UVB, and northern winters. Deficiency is accordingly very common.

What it does, and the claim worth knowing

The authorised claims are unusually strong and specific:

Vitamin D contributes to the normal absorption and utilisation of calcium and phosphorus; to normal blood calcium levels; to the maintenance of normal bones, teeth and muscle function; to normal immune function; and, the one that matters most here, to a reduction in the risk of falling associated with postural instability and muscle weakness in those over 60.

That last claim is specifically about this population, and falls are what turn into hip fractures.

And a fair qualifier: large trials of vitamin D for fracture prevention in unselected, replete older adults have been underwhelming. The benefit is concentrated in people who are deficient, which, in India, is a great many.

How to take it

D3, with a fatty meal, absorption is substantially better.

Daily or weekly dosing, not large infrequent mega-doses. Some trials of very high intermittent doses reported more falls, not fewer, an unexpected and important finding.

And test first. Dose depends on your level.

Cautions

It accumulates, it is fat-soluble.

Caution in kidney disease, kidney stones, sarcoidosis, and hyperparathyroidism.

And check calcium and kidney function on higher doses.

2. Vitamin B12

The one with the most specific age-related mechanism.

Why age changes it

Atrophic gastritis is common in older adults, the stomach lining produces less acid. And acid is needed to release B12 from food protein.

So you can be eating adequate B12 and absorbing little of it. This is why dietary adequacy does not settle the question after sixty.

And two very common additions in India:

Metformin, a documented cause of B12 deficiency, and there are a great many people on it for years. Anyone on long-term metformin should have B12 checked, and this is routinely missed.

Long-term PPIs, same mechanism, less acid.

And a vegetarian diet on top of either makes it close to certain.

Why it matters more than most deficiencies

Because the neurological damage may not fully reverse.

Subacute combined degeneration, peripheral neuropathy, and cognitive and mood effects, treatment stops progression but does not reliably undo established damage.

And the presentation after sixty is frequently cognitive, memory problems, confusion, low mood, which gets attributed to ageing or dementia. It is one of the genuinely reversible causes of cognitive decline, and it is found with a blood test.

And the Indian diagnostic trap

A folate-rich diet can mask the blood picture while nerve damage proceeds. So a normal haemoglobin and a normal MCV do not rule it out here.

If B12 is borderline and symptoms fit, ask about methylmalonic acid or homocysteine.

How to take it

Oral works for most people, because a small fraction absorbs independently of intrinsic factor.

Cyanocobalamin is the studied, stable, inexpensive default.

Injections for severe deficiency or neurological involvement.

And it is remarkably safe, water-soluble, no established upper limit.

3. Calcium, with an important qualification

This one is included with reservations, and the reservations matter.

Why age changes it

Calcium absorption declines with age. Oestrogen loss after menopause accelerates bone loss. And dietary intake often falls as appetite and dairy intake drop.

The qualification

Food first, genuinely.

Milk, curd, paneer, buttermilk, til (sesame), ragi, moringa leaves, green leafy vegetables, almonds, and small fish eaten with bones.

And the reason this matters: high-dose calcium supplements have been debated in relation to cardiovascular risk, and they clearly do cause kidney stones in susceptible people. The evidence for calcium supplements alone reducing fractures is modest.

So the honest position: aim to meet calcium needs from food, and supplement the gap rather than the whole requirement.

And a point we make repeatedly: calcium is the raw material; mechanical loading is the instruction. Calcium without resistance and weight-bearing exercise is bricks with no builder.

How to take it

Split doses, absorption is better at smaller amounts per dose.

With food, particularly calcium carbonate, which needs stomach acid. Calcium citrate absorbs better on less acid, which matters for anyone on a PPI.

And space it from iron, thyroid medication, bisphosphonates and some antibiotics.

Cautions

Kidney stones, hypercalcaemia, hyperparathyroidism, and kidney disease, where it is a medical decision.

And constipation, which is already common in this group.

4. Protein

The one most people would not think of as a supplement, and arguably the most important of the four.

Why age changes it

Two things, and together they are the problem:

Anabolic resistance. Older muscle responds less to a given amount of protein, the threshold to trigger muscle protein synthesis rises with age.

And intake falls, as appetite, taste, dentition and cooking capacity decline.

So requirement goes up while intake goes down. That is sarcopenia’s nutritional engine.

Why it matters

Muscle loss leads to weakness, falls, fractures, loss of independence, poor recovery from illness and surgery, and worse outcomes in hospital.

It is one of the strongest determinants of how the last decades go, and it is more modifiable than people assume.

How to do it

Per meal, not per day. Because of the raised threshold, a day’s protein concentrated in one meal does less than the same amount spread across three.

And breakfast is where Indian diets are weakest, this is the highest-return change.

Food first: dahi, milk, paneer, thick dal, rajma, chana, soya chunks, eggs, fish, besan chilla, sattu.

A powder is legitimate where intake is genuinely short, poor appetite, difficulty chewing, recovery from illness. That is a real need, not a lifestyle purchase.

And protein without resistance exercise builds much less. The two go together.

Cautions

Chronic kidney disease, protein intake is set by your doctor. This is the important exception and it is common in this age group.

And check kidney function before taking large amounts long term.

The fifth thing, which matters most: what to stop

This section is the reason the article is not just a shopping list.

For most people over sixty, stopping things produces more benefit than starting them.

Polypharmacy, and we have written about it separately. Every additional supplement is another interaction risk, another tablet to swallow, and another thing to afford.

Supplements with a poor case after sixty:

High-dose vitamin A or beta-carotene, beta-carotene is associated with raised lung cancer risk in smokers and former smokers, and high-dose retinol affects bone and liver.

High-dose vitamin E, large trials have not supported benefit and raised concerns.

Iron without a diagnosis, and this is important: anaemia after sixty needs its cause investigated, because the default assumption is gastrointestinal blood loss. Iron without investigation is how bowel cancers get missed.

High-dose zinc long term, causes copper deficiency.

Ginkgo, negative trials for dementia prevention, and a real bleeding risk in a population often on anticoagulants and often facing surgery.

Multivitamins as a substitute for testing, they contain a little of everything, often not enough of what you are short of.

And the specific interactions to review with a pharmacist: vitamin K with warfarin; calcium and magnesium with levothyroxine and bisphosphonates; St John’s wort with almost everything; potassium with ACE inhibitors and ARBs; and anything affecting bleeding before surgery.

What is not on the list, and why

Being explicit, because these are the ones marketed hardest to this age group.

Collagen, the oral collagen evidence for joints and skin is weak, and “vegan collagen” is not collagen. Protein and resistance exercise do more.

Glucosamine and chondroitin, mixed and generally unimpressive trial evidence; reasonable to try for a defined period and judge honestly.

CoQ10, a coherent mechanism, better evidence in heart failure than in general ageing. Discussed separately.

Omega-3, genuinely good for pregnancy and infancy; the cardiovascular prevention trials in adults have disappointed. Two portions of oily fish a week beats a capsule for most people.

“Immunity boosters”, the immune system has no dial, and vaccination does far more.

Antioxidant megadoses, repeatedly unimpressive and occasionally harmful in trials.

And memory supplements, where B12, thyroid, hearing, depression and a medication review are the actual answers.

And the things that beat all four

Said plainly, because we would rather be useful than persuasive:

Resistance and weight-bearing exercise. It addresses muscle, bone, balance, glucose, blood pressure and mood simultaneously. Nothing in this article competes with it, and it is free.

Vaccination, influenza annually, pneumococcal, and shingles where available. In this age group this is the highest-value intervention there is.

Treating blood pressure, glucose and lipids.

A medication review.

Hearing and vision checked, untreated hearing loss is associated with cognitive decline, and a hearing aid has better evidence than any supplement here.

Dental care, because it determines what you can eat.

Falls-proofing the house.

And social contact, which is not a soft point.

Claims, our boundary

What is sayable: the authorised nutrient-function claims quoted above, and the vitamin D falls claim and the protein muscle and bone claims are genuinely informative and specific to this group.

What is not sayable: slows ageing, prevents dementia, prevents fractures, treats frailty, boosts immunity, or improves longevity.

What we decline: “anti-ageing” positioning, which is the dominant framing in this category; any dementia claim; and iron products positioned at older adults without a test-first statement, because of the bowel cancer point.

And what we think should be on every supplement sold to this age group: a line saying to show it to your doctor or pharmacist alongside your other medicines. At this age the interaction question is larger than the benefit question.

When to see a doctor

Soon, and before starting any of these:

• Kidney disease, it changes calcium, magnesium, potassium and protein
• A history of kidney stones, calcium and vitamin D
• Sarcoidosis or hyperparathyroidism, vitamin D
• On warfarin or a DOAC, several interactions, and before surgery
• On metformin or long-term PPIs, check B12
• On levothyroxine or bisphosphonates, spacing
• Anaemia, the cause needs finding, not just iron
• Before any blood test, if you take high-dose biotin

Promptly:

• Unintentional weight loss
• Falls, or unsteadiness
• Memory change, or family noticing change, the reversible causes are worth excluding
• Tingling in hands or feet, B12
• Any fracture from a minor knock, this is a signal
• Confusion, dehydration and infection come first
• Low mood or loss of interest for more than two weeks
• Hearing or vision declining
• And a full medication review if you take five or more medicines

The short version

1. These four earn a place because absorption, synthesis and protein efficiency change with age, not because ageing needs supplementing generally.
2. Test, correct, retest. Supplementing an absent deficiency does nothing and sometimes harms.
3. High-dose biotin distorts thyroid and B12 assays, stop before bloods.
4. Vitamin D: skin synthesis declines with age, plus less sun, plus reduced kidney conversion.
5. It has an authorised claim for reducing falls risk in those over 60, specific to this group.
6. Benefit is concentrated in people who are deficient, which in India is many.
7. D3 with a fatty meal, daily or weekly, not large intermittent mega-doses, which did worse on falls.
8. B12: atrophic gastritis means you can eat enough and absorb little.
9. Metformin is a documented cause and is routinely not checked.
10. Long-term PPIs reduce absorption too.
11. B12 nerve damage may not fully reverse, this is why it is urgent, not optional.
12. It presents as cognitive decline after sixty and is one of the reversible causes.
13. A folate-rich Indian diet masks the blood picture, normal MCV does not rule it out.
14. Ask for MMA or homocysteine if B12 is borderline with symptoms.
15. Calcium: food first, supplement the gap, not the whole requirement.
16. High-dose calcium supplements cause stones and the fracture evidence is modest.
17. Calcium citrate absorbs better on low stomach acid, relevant on PPIs.
18. Calcium is the material; loading is the instruction.
19. Protein: anabolic resistance means the per-meal threshold rises with age.
20. Spread protein across three meals, breakfast is weakest in Indian diets.
21. Protein without resistance exercise builds much less.
22. In kidney disease, protein is set by your doctor.
23. The fifth and biggest intervention is deprescribing.
24. Avoid beta-carotene in smokers and former smokers.
25. Anaemia after sixty needs its cause found, iron without investigation misses bowel cancers.
26. Ginkgo has negative dementia trials and a real bleeding risk here.
27. Oral collagen evidence is weak, and “vegan collagen” is not collagen.
28. Resistance exercise and vaccination beat all four.
29. A hearing aid has better evidence than any supplement in this article.
