Fuel & Supplementation: What Actually Moves the Needle
The supplement aisle is built to sell you complexity. The research points the other way — toward a boringly short list, and one habit around protein that matters far more than any pill.
Ask what supplement to take and you're already aiming at the wrong target. For almost everyone, the biggest nutrition lever isn't a powder you're missing — it's when and how much protein you eat.
Most people get enough total protein but distribute it terribly: a sliver at breakfast, a little at lunch, then a giant slab at dinner. Your body can't bank protein. To trigger muscle-building, each meal needs to clear a threshold — and a tiny breakfast simply doesn't, no matter how big dinner gets.
The research points to roughly 0.4 grams of protein per kilogram of bodyweight per meal, spread across three or four meals, as the way to keep the muscle-building signal firing all day. For most adults that's a palm-sized portion of real protein at each sitting — not a tub of anything.
You probably don't have a supplement deficiency. You have a breakfast that's mostly toast.
The plot twist that matters after 40
Here's the part that flips the usual advice. As you age, your muscles become less responsive to protein — a phenomenon called anabolic resistance. The same meal that lit up muscle-building at 25 does less at 65. So older adults don't need less protein to maintain muscle. They often need more per meal to clear the same bar.
It's the cruel irony of aging muscle: exactly when holding onto it matters most, the system gets harder to switch on. The fix isn't exotic. It's protein, at every meal, with intent — and the strength training that makes your body listen.
Studies on protein dosing point to roughly 0.4 g/kg per meal to maximally stimulate muscle protein synthesis, with total daily intake around 1.6 g/kg supporting muscle gain in active people. Aging is associated with anabolic resistance — a blunted muscle response to protein — which is why higher per-meal doses are recommended for older adults.
The supplements actually worth your money
Strip away the marketing and the evidence-backed list is short enough to memorize:
- Creatine monohydrate. The most studied sports supplement there is — safe, cheap, and genuinely effective for strength and power. Notably, it isn't just for the young: in older adults it supports muscle retention and shows promising effects on cognition. Around 3–5 g a day.
- Vitamin D. Worth it if you're deficient, which is common in anyone who spends winters covered up or indoors. Test, then supplement if needed.
- Protein powder. Not magic — just convenient. A practical tool for clearing that per-meal threshold when whole food isn't handy on a busy or active day.
- Caffeine. A real, well-documented performance aid for training and endurance, used sensibly.
Notice what's not on the list: the vast, glossy majority of the supplement aisle. Most of it is built on hope and clever labels, not evidence. The fundamentals are unglamorous because the fundamentals are what work.
The short version
- Protein timing beats supplements — aim for a solid dose at every meal, not one big hit at dinner.
- Target roughly 0.4 g/kg per meal, spread across the day.
- Aging brings anabolic resistance — older adults need more protein per meal, not less.
- The evidence-backed shortlist: creatine, vitamin D (if low), protein powder, caffeine. Most of the rest is noise.
Fueling for the mountains was never about a cabinet full of bottles. Eat real protein at every meal, take the few things that actually work, and let consistency do the rest. Simple isn't a downgrade here. Simple is the edge.
