How much sleep do you need for normal testosterone production?

For adults, 7-9 hours of sleep per night is usually recommended. Testosterone levels begin to rise after you fall asleep, increase throughout the night and are usually highest in the morning, so continuous sleep supports the normal circadian rhythm in testosterone production. If you train a lot and hard, your needs may be at the upper end of the range.

Does a low-fat diet lower testosterone?

Research from 2021 found lower total and free testosterone in men who ate a low-fat diet compared with a diet containing more fat. This does not mean a high fat intake leads to more testosterone, but a very low fat intake over time can be detrimental.

Which exercises are best for stimulating testosterone?

Strength training with relatively heavy weights and exercises that involve large muscle groups, such as squats, deadlifts, rowing and pressing exercises. When several large muscle groups are trained and rest periods between sets are relatively short, the acute increase in testosterone can be greater.

Do testo-boosters actually work?

The effect depends on content, dosage and the user's baseline level. Testo-boosters typically supply zinc, magnesium, vitamin D and vitamin B6, and some contain plant extracts: ashwagandha can give a moderate increase, tongkat ali can increase total testosterone, particularly in men with low levels to begin with, and fenugreek has shown a small positive effect on total testosterone but no significant increase in free testosterone.

Does taking more zinc, vitamin D or magnesium give you more testosterone?

No. The most important thing is to avoid deficiency and ensure the diet meets your needs. A higher intake does not automatically mean a higher testosterone level.

Key takeaways

- A large, prolonged calorie deficit can reduce testosterone production in lean men who train a lot, while the same calorie restriction can raise testosterone in men who are overweight or obese.

- Complete sleep deprivation of at least 24 hours reduces testosterone levels in men, whereas losing a few hours of sleep over short periods did not produce a significant reduction.

- Adipose tissue contains the enzyme aromatase, which converts testosterone to oestrogen, and this is one reason excess body fat is linked to lower testosterone.

- Plant extracts such as ashwagandha, tongkat ali and fenugreek show measurable but modest effects on total testosterone, with the largest effects in men who start out with low levels.

- Natural measures work mainly by removing what suppresses the body's own production, so the potential gain depends heavily on a man's baseline level.

Testosterone plays an important role in muscle growth, strength, and recovery, and is therefore a hormone many men who train are concerned about. The level gradually decreases with age, but is also influenced by factors such as diet, body weight, sleep, and physical activity.

But how much can you influence yourself, and what can actually work as natural testo-boosters?

What you should know about testosterone

What influences your testosterone levels?

Testosterone levels are influenced by factors such as energy intake, body fat percentage, sleep, diet, and physical activity.

A large and prolonged calorie deficit can reduce testosterone production, especially in lean men who train a lot.

Overweight and obesity are also associated with lower testosterone levels, while weight loss can contribute to higher levels.

7-9 hours of sleep provides good conditions for the normal secretion of testosterone and growth hormone throughout the night.

How does strength training affect testosterone?

Strength training can increase testosterone secretion, while excessive hard training without enough recovery can have the opposite effect.

The diet should contain enough fat and meet the needs for zinc, vitamin D, and magnesium, among others.

Testo-boosters often contain vitamins, minerals, and plant extracts such as ashwagandha, tongkat ali, and fenugreek.

How much natural measures and testo-boosters can influence testosterone largely depends on the baseline level and diet.

Does losing weight raise or lower your testosterone?

A large calorie deficit over time can reduce testosterone production. With low energy availability, the activity in the hypothalamus-pituitary-testis axis can be reduced. This regulates the signals from the brain to the testes and thus how much testosterone is produced.

This is particularly relevant for men who train a lot, eat little, and maintain a very low body fat percentage. [Recent research](https://pubmed.ncbi.nlm.nih.gov/34613412/?utmsource=chatgpt.com) shows that calorie restriction can reduce testosterone levels in normal-weight men, and the effect is influenced by how large and prolonged the energy deficit is.

Too much body fat can also lead to lower testosterone levels, but for different reasons. Adipose tissue contains the enzyme aromatase, which converts testosterone to estrogen. In obesity, changes in insulin, inflammatory substances, and signals between the brain and testes can also contribute to lower testosterone production.

The same [research](https://pubmed.ncbi.nlm.nih.gov/34613412/?utmsource=chatgpt.com) simultaneously shows that calorie restriction can increase testosterone levels in overweight or obese men.

The effect of eating less thus largely depends on the starting point: For a lean man who is already consuming little energy, it can be negative, while weight loss can be beneficial for an overweight man.

Sleep is important for hormone production

For adults, 7-9 hours of sleep per night is usually recommended, and several hormones follow the circadian rhythm and sleep stages.

Testosterone levels begin to rise after you fall asleep, increase throughout the night, and are usually highest in the morning. Continuous sleep thus contributes to the normal circadian rhythm in testosterone production.

Also, growth hormone is released in larger amounts during sleep, with a particularly large secretion during deep sleep early in the night. Growth hormone is important for tissue repair and building, and sleep is therefore crucial for both hormone balance and recovery after training.

Too little sleep can disrupt these processes. [Recent research](https://pubmed.ncbi.nlm.nih.gov/34801825/?utmsource=chatgpt.com) shows that complete sleep deprivation for at least 24 hours reduces testosterone levels in men, while short periods of a few hours of less sleep did not result in a significant reduction.

For most people who train, 7-9 hours of sleep is a good goal, but sleep needs vary. If you train a lot and hard, your needs may also be at the upper end of this range.

Strength training and testosterone

Strength training can increase testosterone secretion, especially when you train with relatively heavy weights and exercises that involve large muscle groups.

Squats, deadlifts, rowing, and pressing exercises involve several large muscle groups simultaneously and place high demands on both the muscles and the nervous system.

How strength training is structured also matters. Training for muscle growth typically involves several sets with moderate to relatively heavy weights. When multiple large muscle groups are trained and the rest periods between sets are relatively short, the acute increase in testosterone can be greater.

Can too much training lower your testosterone?

[Recent research](https://pubmed.ncbi.nlm.nih.gov/41527569/?utmsource=chatgpt.com) also shows that excessive hard training can have the opposite effect. Hard training increases cortisol, which contributes to releasing energy during training. If the training volume over time exceeds what the body can recover from, persistent physical stress and high cortisol levels can contribute to reduced testosterone production. Too little food and sleep can exacerbate this.

Testosterone helps build and preserve muscle mass. The hormone binds to androgen receptors in muscle cells, increases protein synthesis, and affects satellite cells, which contribute to the growth and repair of muscle fibers. The anabolic effect also explains why the supply of extra testosterone can lead to greater increases in muscle mass and strength.

Muscle growth takes time, and more training does not necessarily lead to faster progress if the body does not have time to recover between sessions.

Which nutrients does testosterone production depend on?

The diet should provide enough fat, vitamins, and minerals that the body needs for normal hormone production.

[Forskning fra 2021](https://pubmed.ncbi.nlm.nih.gov/33741447/) found lower total and free testosterone in men who ate a low-fat diet compared to a diet with more fat. This does not mean that a high fat intake leads to more testosterone, but very low fat over time can be detrimental.

Several vitamins and minerals are also relevant:

- Zinc: Plays an important role in testosterone production. [Recent research](https://pubmed.ncbi.nlm.nih.gov/36577241/) shows that zinc deficiency is associated with lower testosterone levels. Good sources include meat, shellfish, eggs, dairy products, nuts, and seeds.

- Vitamin D: Is important for normal muscle function and the immune system, among other things. We get vitamin D from fatty fish, eggs, and fortified foods, while the skin produces vitamin D when exposed to sunlight.

- Magnesium: Is necessary for normal muscle function, energy metabolism, and protein synthesis. Good sources include nuts, seeds, whole grains, legumes, and green vegetables.

The most important thing is to avoid deficiency and ensure that the diet meets the needs. A higher intake does not automatically mean a higher testosterone level.

Tests Testobooster – Best in test 2026 – Top 10

Aug 21, 2026

Can testo-boosters have an effect on testosterone levels?

Many testo-boosters can in some ways be compared to a targeted vitamin and mineral supplement, but often contain plant extracts as well.

Zinc, magnesium, vitamin D, and vitamin B6 are common ingredients. Several products also contain plant extracts where research has shown that some can contribute to higher testosterone levels:

- Ashwagandha: [Recent research](https://pubmed.ncbi.nlm.nih.gov/41740946/) shows that ashwagandha can provide a moderate increase in testosterone in men. Results vary between studies, partly because different doses and extracts have been used.

- Tongkat ali: [Research from 2022](https://pubmed.ncbi.nlm.nih.gov/36013514/) suggests that tongkat ali can increase total testosterone. The effect appears to be greatest in men who have low levels to begin with.

- Fenugreek: [Research from 2023](https://pubmed.ncbi.nlm.nih.gov/37253363/) found a small positive effect on total testosterone, while no significant increase in free testosterone was found.
