Search this question and you’ll find a wall of supplement ads. The honest answer is less marketable and more useful: a handful of ordinary things move testosterone meaningfully, and almost everything sold in a tub does not.

Here’s what’s actually worth your effort, roughly in order of impact.

Sleep

Most of your daily testosterone is released while you sleep, concentrated in the hours of deeper sleep early in the night. Cut sleep short and you cut production directly. Studies restricting healthy young men to around five hours a night have measured meaningful drops in daytime testosterone within a week.

If you’re routinely getting five or six hours, this is the single highest-value change available to you, and it costs nothing. It’s also the one most men skip past looking for something they can buy.

Untreated sleep apnoea

Worth separating from sleep generally, because it’s common, frequently undiagnosed, and it suppresses testosterone independently of hours in bed. If you snore heavily, wake unrefreshed, or your partner has noticed you stop breathing, get assessed before you do anything else.

This matters clinically too: untreated sleep apnoea is a reason testosterone therapy would be deferred, because treatment can worsen it. Sorting it out sometimes resolves the hormone problem entirely.

Body fat, particularly around the middle

Visceral fat contains aromatase, the enzyme that converts testosterone to oestrogen. More of it means more conversion and lower testosterone, and lower testosterone makes fat harder to shift. It’s genuinely self-reinforcing, which is why so many men feel they’re pushing against something.

Weight loss reliably raises testosterone in men carrying excess weight, and the effect scales with how much is lost. It is slow, and it is the most evidence-backed natural intervention there is.

Resistance training

Lifting produces a short-term spike in testosterone that, on its own, means very little. The real benefit is indirect and substantial: more lean mass, less visceral fat, better insulin sensitivity, better sleep. Those shift your baseline.

Chronic overtraining without adequate recovery or food does the reverse. More is not automatically better here.

Alcohol

Heavy or regular drinking suppresses testosterone through several routes, including direct effects on the testes and on liver metabolism of hormones. Occasional moderate drinking isn’t the issue. A bottle of wine most nights is.

Correcting actual deficiencies

If you’re genuinely deficient in vitamin D or zinc, correcting that can improve testosterone. The important word is deficient. In men with normal levels, supplementing further does nothing, which is why supplement trials produce such inconsistent results — they mix deficient and replete people together.

This is testable rather than guessable.

Medications worth reviewing

Opioids are a significant and under-recognised cause of low testosterone. Long-term corticosteroids and some antidepressants can contribute too. Never stop a prescribed medicine on your own — but it’s worth raising with whoever prescribed it, because there may be alternatives.

Chronic stress

Sustained high cortisol suppresses testosterone production. Hard to measure and harder to fix, but if you’ve been running at a deficit for two years, it’s part of the picture rather than an excuse.

When lifestyle isn’t enough

Plenty of men do all of this properly and still have clinically low testosterone. Genuine primary hypogonadism — where the testes aren’t producing — doesn’t respond to better sleep. Nor does pituitary dysfunction, Klinefelter syndrome, or long-term suppression following anabolic steroid use.

Lifestyle work is worth doing regardless. It’s also not a reason to leave symptoms uninvestigated for another two years hoping they’ll resolve. If several symptoms have persisted for months and haven’t shifted with genuine effort, that’s the point to get your bloods done properly and find out what you’re dealing with.
