How to raise testosterone

Why is testosterone so low now? We’ve discovered that the light of your computer screen is crushing your testosterone by killing your dopamine neurons. Computer screen light is the key thing holding your testosterone down.


  • The light from your computer screen shoots into your eye.
  • Your eye is the most sensitive path into the brain. The computer light enters deep into your brain and kills your dopamine neurons.
  • Low dopamine means no energy and no motivation, and your body stops producing high testosterone. Dopamine raises testosterone. No dopamine = no testosterone.

Computer screens kill dopamine because they transmit rapidly flashing LED light into your brain. (Detailed science is further down this page)

How do we fix this? The only full solution is an E-Ink Screen.

E-Ink screens are computer screens that produce no light at all. That’s the key reason E-Ink screens make your dopamine stay high, no LED light glaring into your eye and brain. E-Ink screens are just like a sheet of paper. You’ve probably seen them on E-Readers like the Kindle. That technology is now available for computers too.

E-Ink is the only real way to stop your computer from wrecking your dopamine and your testosterone because there is zero harmful LED light entering your eye like on a normal computer screen.

Here’s the best E-Ink screen I know:

DASUNG E-Ink Paper Like 3 HD Front-Light Touch 13.3″ Monitor – Silver

It plugs right in with an HDMI cable. Turn off your old LED screen and use your E-Ink screen and you’ve stopped the flood of dopamine-destroying LED computer light shooting straight into your brain. Your brain can go back to normal and produce high dopamine and high testosterone. That means energy, focus, and motivation. E-Ink screens raise testosterone.

You won’t believe the difference an E-Ink screen makes. It’s by far the most valuable change I’ve ever made for my health and energy.

You can also get an E-Ink tablet (like a normal Android tablet, but it’s E-Ink instead of that glaring LED light). I think the E-Ink monitor will be more useful though, because you can do your office job on it.

Your TV and your phone are also dopamine destroying LED screens – if you have to watch TV (you don’t) then watch it through your E-Ink monitor. LED screen TV’s kill testosterone because of that dopamine wrecking light they produce.

Raising testosterone with natural light

The most important thing for dopamine and testosterone is to STOP the flood of LED computer and TV screen junk light. That’ll take you from 400 ng/dl testosterone (way too low) to 550 ng/dl (not bad!)

But the next most important thing is to get natural light from the sky and the sun. That takes you the next step in raising testosterone, from 550 ng/dl testosterone to 700 ng/dl (now we’re talking!)

Natural light raises dopamine and testosterone. Remember how the eye is the sensitive pathway into the brain? That’s why computer light is so bad for you, but it’s also why natural light from the sky and sun is so good for you. Your eye was designed to have natural light coming into it and going right into your brain where it produces dopamine and that dopamine produces testosterone. That’s how you get serious energy and motivation, naturally.

This is the key to restoring your body and brain to the way they are designed to work in nature. It’s a million times better than TRT or other weird interventions. TRT makes you go bald (because it lowers epitestosterone – barely anyone will tell you that).

The natural light protocol has three parts:

  • Good bright daylight in the morning after waking up. Morning light is a key signal to your brain that aligns your whole body with the natural system.
  • A minimum of two hours bright, outdoor light per day. Put yourself right by a window if you need to be inside. And get outside as much as you can. Two hours is a minimum – that’s the cutoff before dopamine lowers in your eyeball (which causes nearsighted bad vision). More hours are better. Follow what feels good to you. You’ll probably feel like spending about half the day outside and half the day in more shady cool zones. That’s great – follow your instincts.
  • At least an hour before bed should be in red or orange-tinted light and not super bright, or even darkness. I like a candle, firelight, the sunset, and incandescent light bulbs (in place of LED light bulbs). These have the right color wavelengths to get you ready for bed. They are also steady lights that don’t rapidly flicker, so they let your brain relax.

And once again: Eliminate the LED computer/TV screen light. It’s killing your dopamine and your testosterone (and other hormones too, and it’s just as bad, maybe worse, for women and children too). Eliminate those bright screens and replace with E-Ink if you must have a screen.

Why does this raise testosterone and dopamine?

All your body is regulated by your mind. To do that, neurotransmitters in your brain are critical. Dopamine is a neurotransmitter. Dopamine is essential to energizing and focusing your body and brain. Parkinson’s Disease is what happens when dopamine function fully declines. Dopamine is the key to focus, motivation, and stopping procrastination. (If you suffer from that, you may have low dopamine.)

Testosterone is produced when the brain calls for it. The  brain and the glands can tell your body to produce as much testosterone as they want. They could produce testosterone levels only seen in steroid users if they wanted to.

Excess amounts of the hormone Prolactin are absolutely death for your testosterone. Dopamine directly stops Prolactin. By stopping Prolactin, Dopamine greatly increases Testosterone.

Giving a dopamine agonist (an increaser of dopamine) to patients with excess prolactin lowered their prolactin from 1761 mU/L (way too high) to 210 mU/L (normal) and raised their testosterone from 214 ng/dl (extremely low) to 496 ng/dl (a lot better!) – and these guys were hemodialysis patients so they weren’t doing too well, otherwise their testosterone would be a lot higher. (source)

Another group of men with low testosterone were given a dopamine agonist. Every one of the low testosterone men achieved normal testosterone, and those with high prolactin (most of them) achieved normal prolactin. (source)

Dopamine also opposes the inappropriate excess of stress hormones like cortisol, which are potent at crushing testosterone. Cows injected with a dopamine antagonist (blocks dopamine) had their prolactin rise from 14 ng/ml to 103 ng/ml and their cortisol rose from ~7 ng/ml to ~20 ng/ml. (source) When dopamine is blocked, both prolactin and cortisol rise high. Both prolactin and cortisol lower testosterone a lot.

One researcher got 1500+ ng/dl testosterone without injecting steroids, TRT, or anything. (source) He increased dopamine by stopping his excess production of brain chemicals that block dopamine. He got literally off-the-charts testosterone. He did this with a special ratio of the natural amino acids BCAAs+Tyrosine+Sunlight and Vitamin E, among a few other things. I don’t advise doing this protocol (and he himself didn’t advise it either) as it is much better to get the brain thriving naturally, the way it wants to! You do that by giving the brain the environment it’s meant to thrive in. That means getting the input of Light right. Hunter-gatherers living outside in the sun without computer screens consistently average 900 ng/dl testosterone. Quite a few of them are over 1500 ng/dl testosterone. A few are over 2000 ng/dl. (Source)

Unnatural light entering the brain hurts dopamine. This study on rats showed that florescent light reaches right into the brain and kills your dopamine neurons. But near-infrared light improves the dopamine neurons. (Source) There’s basically zero near-infrared light in LED computer screen light, but there are huge amounts of near-infrared light in sunlight.

Outdoor light increases dopamine in the eye. This actually has told scientists the cause of near-sightedness! Dopamine keeps the eye the right shape. Without enough light, there isn’t enough dopamine, and the eye goes the wrong shape, producing near-sightedness. Following this research, Taiwan has commanded its schools to provide 2 hours of outside time per day for the kids. Taiwan had a cataclysmic increase of nearsightedness up to 90% of the population until they just recently started to let the kids spend at least two hours outside. Doing this has finally begun to reverse their nearsighted epidemic. (source) That is the power of dopamine and the sunlight!

Parkinson’s Disease is strongly related to a loss of dopamine. Those who spend lots of time outside have a lower risk of getting Parkinson’s. (source)

Computer workers have a 1.31x higher risk of dying from Parkinson’s than the average, while construction workers (who are outside a lot) have a below average risk of Parkinson’s death, 17% lower than the average. Putting it another way, computer workers have a 58% higher risk of dying from Parkinson’s than construction workers do. Transportation workers, which I guess mostly means truck drivers, also have similarly low risk of Parkinson’s, even slightly lower than the construction workers. They are looking out at the outdoors most of the day while driving the truck. (source)

The US and Canada have had an increase in Parkinson’s from ~40,000 in 1990 to ~75,000 in 2010 to ~165,000 in 2019. You can see that not only has it risen a lot, but the rise in Parkinson’s accelerated greatly after 2010, approximately when LED lit screens (LCD screens) were introduced. (CRT screens were before that and I don’t think they were good either, but maybe not as bad) Meanwhile the “undeveloped” parts of the world like Sub-Saharan Africa have barely any Parkinson’s. These places currently average under 5000 compared to our 165,000. And East Asia, the places where they get so little outdoor light that 90% need to wear glasses, has the very highest rates of Parkinson’s too. (source)

Testosterone levels in most parts of the world have dropped from at least 1980 to the current day. However, in the US, testosterone didn’t drop at an even rate. In 1988-1991, testosterone was ~540 ng/dl in the US. It had dropped from a higher number before that, but 540 is still adequate. Then, when measured again in 2003-2004, testosterone was still 540 ng/dl. Still not bad! However, when they measured testosterone in 2011-2012, it was 440 ng/dl, which is not good at all. That’s a sudden drop from pretty good to pretty bad. So testosterone in the US stayed about the same for 14 years, but then dropped hard somewhere between 2004 and 2011. I don’t think there were major diet changes during this time. But what did change was the introduction of LED backlit screens in TV’s and computers. Before that, we used CRT screens which are probably not quite as bad.

The testosterone trend in the USA from 1960 to 2023

What about testosterone by occupation? Computer workers average 413 ng/dl testosterone in the US in 2013-2014. Not even one of them got any higher than the 600’s ng/dl. But the transportation workers (I assume truck drivers) averaged 505 ng/dl testosterone. Truck drivers of course are looking outside most of the day.  Three of them were over 1000 ng/dl. Construction workers were 467 ng/dl, which is higher than the computer workers, but still not very good. I’m guessing their lowish testosterone is partly due to the chemical fumes they are exposed to. (you may notice that agriculture workers are low on the chart too – surely it’s the pesticides.)

So avoid artificial light and get natural light so your dopamine stays high and your testosterone is naturally good!

You should also avoid chemicals like pesticides, synthetic fabrics like polyester underwear, and bad food ingredients like degraded deep-frying oil (almost every restaurant is bad on this) and emulsifiers like guar gum and carrageenan. Also make sure to get good deep sleep, an abundance of nutrition, and to avoid excess over-exercise but still move around a lot. These are all very important things for testosterone as well.

Does Testosterone vary through the year?

Several studies have asked this, with differing results. But some find that testosterone does appear to vary through the year to a moderate degree. It usually peaks around the Autumn, then drops through the winter to a low in the Spring.

Paris 1975: five healthy medical students and biochemists living in Paris age 26-32. “The peak of plasma testosterone was in November (909 ± 42.7 ng/dl) and the trough was in May (640 ±51.1 ng/dl)”) (source)

1974-1975 in Nijmegen, The Netherlands: 15 healthy men age 24-45. Testosterone averaged 666 ng/dl in April 1974, 744 in July, 762 in October, 665 in January 1975, and 631 in April 1975. (source)

That was the average, but there was a lot of individual variation. Some men peaked in July and some peaked in October. One man looked like this: April: 781 ng/dl, July: 1084, October: 1144, January: 586, April 778. That guy didn’t like January much! However, most of them did not change as much as that. Maybe that guy had very low Vitamin D or something.

Boston, Massachusets in the USA in the 2000’s  – Among 30-79 year old men, testosterone rose until July, reaching 470 ng/dl, and then began dropping to a low in December of 385 ng/dl (source) The study didn’t find the differences to be significant however.

How much onion to increase testosterone? Perhaps none

If you look around on the internet, you’ll hear claims that onions increase testosterone, and all kinds of other statements like that.

Just how much onion does it take to increase testosterone? Well, the one study done on humans showed no major testosterone increase, but we can tell you how much the rats in the other studies ate.

To match what the rats ate, a person would need about 2 onions per day.

Doing the math

Here’s why. Most studies were done on rats. Studies usually used onion juice between 0.5 ml and 6 ml daily, per rat. (source) If that was a 670g male wistar rat, then equivalent amount of onion juice for a 180 lb man would be 61 ml to 731 ml of onion juice daily. 61 ml is something like as much as there is in 2/3 of an onion, and 731 ml is about as much as there is in a little under 8 onions. (These are all very rough estimates) To match the amount that most of the studies used, you’d probably eat about 2 onions worth of juice daily.

Don’t eat tons of onions though

But the real answer is that stuff like this really isn’t the ideal way to improve your health and hormones. As I mentioned, the study that fed humans onion extract found no major effect on testosterone. Being lean, sleeping enough, and eating a nutrient dense and natural diet are probably way more effective for increasing testosterone.

I also can’t say what eating 2 onions every day might do to your body, it might be hard on your digestion, and I know I would get sick of it quickly.

So how can we raise testosterone then?

However, it’s understandable that people are looking for testosterone boosting advice other than “get healthy,” since even healthy and fit people today seem to have lower testosterone than people in the past did. Our site has extensive discussion of the fall of testosterone levels over the years.

Why is testosterone low today, even in healthy and fit people? It probably isn’t because we eat less onions… We aren’t sure what exactly is making testosterone levels fall, but we have identified a few things.


Countries with lots of pesticide usage have lower testosterone on average.

More discussion of that in our article.

Endocrine disruptors and hunter gatherers

Endocrine disruptors are chemicals that mess up your hormones. People in the past (when testosterone was higher) were not exposed to these chemicals.

Hunter gatherers are mostly not exposed to endocrine disruptors and we’ve collected data here showing that their testosterone is frequently much higher than ours, sometimes more than double on average. (Our article about that)

Common sources of endocrine disruptors are skin products like shampoo, moisturizer, and sunscreen. Another source is microplastic dust from polyester clothes, carpets, and furniture.

Safer, more natural shampoo is available here: Baby Shampoo & Body Wash by Dapple Baby.

Polyester fabric can be replaced with natural fabric like 100% cotton or 100% wool. You can put a 100% cotton sheet over top of polyester fabric furniture to prevent the polyester from putting microplastic dust into the air in your house.

Clothes, and especially underwear, ought to be cotton or wool. Beware of blends that claim to be cotton or wool but are actually partly polyester or another synthetic fabric. It’s kind of hard to find truly 100% cotton or 100% wool underwear, so we saved you the trouble:

100% merino wool boxers:

And some 100% cotton boxers:

What’s the bottom line?

In conclusion, eating natural food (ideally organic), minimizing the use of skin products that have anything weird in them, and minimizing microplastic dust from synthetic fabrics are all valuable things you can do to keep your hormones healthy (once you have made sure you are sleeping well and getting healthy and lean in general). Clever tricks like eating onions really aren’t something you have to focus on.

Good luck!

Our favorite moisturizer without endocrine disruptors

These moisturizers have no endocrine disruptor chemicals like phthalates or PFAS. There should be nothing but natural ingredients in a moisturizer without endocrine disruptors. Of course, the best moisturizer is the one that you enjoy and get the best results from. You should like the smell and the feel of it, and it should work well for you.

Tallow, honey, and shea butter

We like moisturizers that are all natural. We don’t think there should be any ingredients that sound like a chemistry experiment, even if they are mostly safe. To really protect the hormones, we think it’s best to stay 100% natural. That’s why our top picks contain nothing but beef tallow, honey, shea butter, or essential oils. These are all natural products quite close to their natural state.

Xenoestrogens on my skin? No thank you!

The synthetic, commercial products you might see at the store contain a variety of weird chemicals. Many of the chemicals are endocrine disruptors, specifically they are artificially estrogenic, which is why some of them are also known as xenoestrogens.

Phthalates are common in most moisturizers since they have an ability to moisturize the skin.  But it is not worth it! Phthalates are xenoestrogens, meaning that they will increase risk of breast cancer and hormonal mood swings. Our recommendations are free of phthalates.

Should you really put tallow on skin?

Yes! Reviewers report great results when they use the tallow and honey balm. They say it feels great, with no icky mess at all. And they report seriously good results from the balm. Skin clears up, and dry skin goes away and stays away.

Use a moisturizer without endocrine disruptors for beautiful skin.

Tallow and honey both nourish the skin. They contain powerful natural compounds that your skin craves.

Tallow and honey together make the best moisturizer without endocrine disruptors

We like the tallow and honey balm best of all. There is absolutely nothing unnaturally hormone-damaging in it. It has no weird chemicals that might cause mysterious bad health effects. Tallow and honey are both near-superfoods full of healing and rejuvenating parts. Honey has been known for centuries to facilitate healing.

Shea butter is a good moisturizer too!

Shea butter is another good moisturizer without xenoestrogens. If you are looking for a vegan option, you should go with this one, since it comes from a tree.

Sunscreen without endocrine disruptors

It’s important to use sunscreen without endocrine disruptors. These sunscreen products are free of harmful chemicals like this. Endocrine disruptors are chemicals that damage your hormone levels. Endocrine disruptors are associated with breast cancer. Unfortunately, many sunscreens have these chemicals.

Physical sunscreen vs chemical sunscreen

There are two ways to block UV rays from damaging your skin. One is a chemical sunscreen – these are invisible on your skin. The other way is a physical sunscreen, which literally coats your skin so the sun is reflected off instead of reaching your skin. These are always a layer of visible color on top of your skin, because they have to physically block the sun’s rays. Unfortunately, there isn’t currently any chemical sunscreen without endocrine disruptors. They’re all physical sunscreens. Hopefully in the future someone will invent one, perhaps using certain promising herbal ingredients. (Like these)

Either the sun will burn you or you'll be exposed to chemicals if you don't use a sunscreen without endocrine disruptors!
The jolly sun will burn you, unfortunately, if you don’t take care!

Common endocrine disruptors in sunscreen to avoid

Oxybenzone (also known as Benzophenone-3), PABA, and homosalate are all common endocrine disruptors found in sunscreens, but not in the ones we listed. Since these chemicals have artificial estrogenic activity, they are called “xenoestrogens.” (source) Using sunscreen without xenoestrogens is imperative if you want to lower risk of breast cancer, or keep testosterone levels where they naturally should be. You should definitely use one of the xenoestrogen-free sunblocks listed here instead of a hormone-damaging one from the store.

What about olive oil or raspberry oil for sunscreen?

Unfortunately,  most of these simply don’t seem to work. They don’t really block the sun. Someone tried putting these on different patches of skin and found that the “natural” DIY sunscreens simply don’t protect the skin much at all. Link:

It seems that carrot oil may have some ability, based on this test:

And raspberry oil may have some minor ability to block the sun as well.

Sunscreen that doesn’t lower testosterone

One of the big effects of endocrine disruptor chemicals like those found in some sunscreens is to lower testosterone. Since there is something of a low testosterone plague going on, probably due to the various chemicals in the environment, it is pretty important to be careful about only using a sunscreen without endocrine disruptors.

Other chemicals to avoid

We also want to avoid parabens and other strange chemicals in sunscreen. The ones we recommend are free of these things.

More things you can do to avoid sunburn

Simply staying out of the sun when your skin is vulnerable to sunburn is the best thing you can do. Always bring a coverup or have access to shade.

Only get as much sun as your skin can handle. While it’s true that the sun is good for you, it is still very bad for you to get sunburned. It is radiation damaging your skin and you don’t want this!

Apparently, Vitamin C, avoiding seed oils in your diet, and Vitamin E will all help you be a bit more sunburn resistant, but you shouldn’t rely on this at all.

Timing your sun exposure to avoid sunburn

If you get sun before 10am and after 4pm (or pre 11am & post 5pm during daylight savings time) then the sun doesn’t really contain as much UV light that burns you. You can get lots and lots of this sunlight and experience the healthy effects of bright and red wavelength light on you, without worrying so much about being burnt. Then you can get maybe 15 minutes of full body UV sunlight during the middle of the day to get your Vitamin D.

Testosterone levels in Bangladesh

In Dhaka, Bangladesh in 2015, testosterone was 423 ng/dl.

Is Bangladesh’s average testosterone level lower than the testosterone levels in other places in the world?

Much of the world is having an unusual, unexplained fall in testosterone since about 1980, at least. Bangladesh is unfortunately not spared from this problem. The low levels of testosterone here are pretty similar to those found after the rest of the world’s decrease. Unfortunately we don’t have historical data from Bangladesh to see what testosterone levels used to be here, but the levels would likely have been a lot higher and healthier, since we have data showing other countries in South Asia with higher testosterone in the past than what they have today.

Testosterone levels in Belgium

In the land of Belgium around 2008, the average man’s testosterone was 561 ng/dl.

Is testosterone in Belgium lower than the testosterone levels in other places in the world?

Testosterone is decreasing in many places around the world. (We think that the blame can be placed on chemicals called endocrine disruptors and seed oil in the diet) Belgium has had some decrease in testosterone like many other places. However, they’ve still maintained pretty good testosterone levels, and their current level isn’t as bad as most other places. So that’s good! If you’d like to know more, please see the article on this site about how testosterone has fallen.

What’s the average testosterone level in the other countries?

Testosterone is decreasing in many places around the world. (In our opinion it’s chemicals called endocrine disruptors and seed oil in the diet) Unfortunately, this is happening in Brazil too, which is having a decrease in testosterone like most other countries, and is now quite low. We think it might be Brazil’s heavy use of pesticides that’s doing it. If you’d like to know more, you can check out our article on how and why testosterone has fallen over the years.
