Protein needs go up rather than down, absorption of one key vitamin declines, and the most useful supplement is one most men have never considered.
Start With What Changes After Fifty
Muscle becomes harder to build and easier to lose, stomach acid production falls, bone density declines quietly, and appetite regulation shifts. Almost every recommendation below follows from one of those, and none of it requires eating less.
More Protein, Not Less
This is the big one. Older muscle responds less efficiently to protein, an effect researchers call anabolic resistance, so requirements go up rather than down. Many nutrition bodies now suggest older adults aim well above the standard adult guideline, and active men higher again.
Spread It Across the Day
Most men eat very little protein at breakfast and a large amount at dinner, which wastes most of it. Muscle protein synthesis responds better to roughly 25 to 30 grams at each of three meals than to the same total loaded into one. Eggs or Greek yoghurt at breakfast fixes this in a week.
Oily Fish Twice a Week
Salmon, mackerel, sardines and herring for EPA and DHA. UK guidance is two portions of fish a week with at least one oily, and most men manage neither. Tinned sardines are cheap and count fully.
Vitamin D From October to March
This is official UK advice rather than a wellness claim. Everyone in Britain is advised to consider a daily supplement of 10 micrograms through the darker months, because there is not enough sunlight at this latitude to make it. Men over fifty have a real interest in it for bone health.
Calcium and Vitamin K for Bone
Osteoporosis is widely assumed to be a women’s condition and it is substantially underdiagnosed in men. Dairy, fortified alternatives, tinned fish with bones, and leafy greens for vitamin K. Anyone taking warfarin needs to keep vitamin K intake steady rather than changing it suddenly.
Creatine, Which Is Not Just for Young Men
One of the most studied supplements there is, cheap, and increasingly supported for older adults combining it with resistance training for muscle and strength. Around three to five grams a day of creatine monohydrate. Check with a GP first if you have any kidney concern.
Magnesium From Actual Food
Involved in muscle function, sleep and blood pressure, and intake is commonly low. Nuts, seeds, wholegrains, dark chocolate and leafy greens. Food sources are a better starting point than a supplement for most men.
Fermented Foods and Plant Variety
Kefir, live yoghurt, sauerkraut and kimchi, and a wider range of plants across the week rather than the same five vegetables. Gut microbiome diversity declines with age and is one of the more promising areas of current nutrition research.
Fewer Ultra-Processed Foods
Not a moral point. Ultra-processed food tends to be high in salt, low in fibre and easy to overeat, and it displaces the things on this list. Reducing it is usually more effective than adding anything.
Get Bloods Done Rather Than Guessing
A GP check covering B12, vitamin D, cholesterol, blood sugar and kidney and liver function turns all of this from guesswork into something specific to you. It is also the right place to raise any supplement before starting it, particularly alongside existing medication.
