A couple of years again, PN co-founder John Berardi, PhD, posted a shirtless photograph of himself on his forty seventh birthday.
He referred to as it his “anti-regress pic” and thanked 30 years of squats, deadlifts, presses, and chin-ups—amongst different workouts—for his chiseled six-pack, pumped chest, and bulging biceps.
The query many commenters posed:
“Are you on testosterone?”
Dr. Berardi defined in a follow-up put up that whereas he wasn’t in opposition to testosterone substitute remedy (TRT) for individuals who wanted it, he himself was not on this remedy, and his testosterone ranges had been boringly “normal.” He additionally provided some thought-provoking concepts about testosterone and growing older.
Dr. Berardi’s take is the alternative of what you usually hear, particularly lately when…
- The mainstream opinion appears to be that declining testosterone is a harbinger of growing older, frailty, and impotence—to not point out a risk to masculinity.
- Increasing numbers of middle-aged males are ditching conventional medical checkups for males’s-focused telehealth clinics specializing in testosterone enhancement.1

- Media retailers pump out story after story about “testosterone boosting” meals to eat and “testosterone lowering” meals to keep away from.
Whether you’re a coach who fields the “How do I optimize testosterone?” query from purchasers—or only a common dude hoping to age nicely—it’s straightforward to really feel overwhelmed and confused by the conflicting data.
Are declining testosterone ranges regular?
Do testosterone-boosting complement regimens really work?
Who advantages from testosterone remedy—and who doesn’t?
In this story, we’ll discover these questions and extra.
What is testosterone?
Secreted by the testes, testosterone is the intercourse hormone chargeable for male sexual traits resembling massive muscle mass, deep voices, and bushy chests. It’s a chemical messenger that performs a key position in varied processes all through the physique, together with sperm manufacturing and bone density.
(In girls, who additionally want testosterone to maintain varied processes buzzing, testosterone is secreted by the ovaries and adrenal glands. Their our bodies simply make a lot much less of it; about 10 to twenty occasions lower than males.)
Possibly due to its relationship with muscle progress and intercourse drive, a whole lot of cisgender males consider testosterone in binary phrases, with decrease testosterone being unhealthy and better testosterone being good.
However, it’s extra correct to consider the connection between testosterone and well being as a continuum that goes from too low (problematic) to too excessive (additionally problematic), with the wholesome vary falling between the 2 extremes, says Denise Asafu-Adjei, MD, MPH, urologist, males’s well being professional, and assistant professor of urology at Loyola University Chicago-Stritch School of Medicine.
As the chart beneath exhibits, the risks of extraordinarily low testosterone are just like the dangers of extraordinarily excessive quantities (sometimes solely achievable with the usage of anabolic steroids).

Low testosterone vs. decrease testosterone
Testosterone ranges naturally ebb with age, with most males dropping about 1 to 2 % yearly beginning round age 40. By age 75, most males have 30 % much less of the hormone than they did at age 25.2
(Fun truth: Between ages 25 and 80, males can anticipate their testicles to shrink 15 %.3)
However, age-related drops in testosterone usually are not the identical factor as “low testosterone.”
Hypogonadism is the medical time period for low testosterone ranges, and it impacts about 35 % of males older than 45 and 30 to 50 % of males who’ve weight problems or sort 2 diabetes, in line with the Endocrine Society, one of many skilled public well being organizations that units hypogonadism therapy tips.
Not solely can overly low testosterone make you are feeling fatigued and do a critical quantity in your intercourse drive, however it will probably additionally hurt your bone and cardiovascular well being, says Dr. Asafu-Adjei.
“You need testosterone for good bone strength,” says Dr. Asafu-Adjei. “As you get older, you’re already dealing with weaker bones, so having lowered testosterone isn’t going to help.”
Alternatively, bringing ranges as much as regular appears to supply cardiovascular advantages, she says. (The massive caveat right here is as much as regular—not far above it.)
The significance of referring out
What in case you or your consumer have many of the hallmark signs of hypogonadism however nonetheless have blood ranges of testosterone within the regular vary?
“Many men over 30 who feel down or low energy will now automatically blame their testosterone,” says Dr. Asafu-Adjei. “Their symptoms might be related to testosterone, but they also could be related to not sleeping, stress, or some other factor.”
That’s why seeing a healthcare skilled specializing in males’s well being and testosterone administration is so essential.
Such a doctor can display you or your consumer for dozens of different issues (like stress and poor sleep) and situations (like diabetes, weight problems, or sleep apnea) that both mimic the signs of hypogonadism or intrude with the manufacturing or signaling of testosterone.
In different phrases, supplemental testosterone is the reply for some males with signs of hypogonadism, however not all of them. An intensive workup is required.
“There are overlapping symptoms with low testosterone as well as a lot of nuances around hormone treatment,” says Dr. Asafu-Adjei.
“For example, outside of your total testosterone, we also look at your testosterone-to-estrogen ratio and other related hormones. That’s why it’s so important to go to someone who knows what they’re doing. They’ll take a deeper dive to figure out the root of the problem.”
So, in case you concentrate on teaching middle-aged and older males, get a urologist or endocrinologist in your referral community.

Testosterone and aggression
Many folks assume that, in excessive quantities, testosterone turns males into pushy, road-rage-fueled jerks. However, the affiliation between the hormone and habits is rather more complicated.4
As it seems, each an excessive amount of and too little testosterone can result in irritability.
In addition, the hyperlink between testosterone and aggression relies upon rather a lot on somebody’s character, upbringing, context, social norms, and extra.
For instance, in a single experiment, researchers requested forty younger males to play a online game that concerned accepting and rejecting provides from a proposer. If somebody deemed the proposal too low, they might reject the provide and punish the particular person for making such a substandard ask. Alternatively, in the event that they thought-about the provide helpful, they might settle for it in addition to reward the particular person.5
Researchers injected a number of the males with testosterone as they performed the sport.
As anticipated, gamers handled with the hormone had been extra prone to punish proposers, particularly in the event that they thought-about the provide unfair. However, in the event that they perceived the provide as honest, they rewarded the proposer extra generously.
The elevated testosterone amplified aggression, but additionally generosity.
Some researchers check with this phenomenon as “the male warrior hypothesis,” which holds that testosterone might perform to assist some males shield and cooperate with their “in group” (resembling their household, buddies, and coworkers) whereas concurrently punishing anybody seen as an outsider.6
7 evidence-based methods to optimize testosterone… naturally
On the Internet, in case you search for methods to spice up testosterone by life-style, you’ll shortly change into inundated with complement suggestions and lists of T-boosting and T-harming meals.
However, research-supported methods to optimize testosterone usually middle on the elemental dietary and life-style measures you’ve lengthy heard are good for you.
They embrace the next:

Your physique prioritizes pondering (your mind) and motion (your muscle mass) above intercourse (your reproductive organs).
Think about it this manner: If there was a famine, the very last thing you’d want is one other mouth to feed.
So, whenever you chronically burn extra energy than you eat, hormone ranges usually drop. (This is true in each women and men.)
“A lot of men in their 20s and 30s come to me about their low testosterone levels and their low testosterone symptoms,” says Dr. Berardi. “These are mostly guys who prioritize exercise. They work out a lot and watch what they eat. In other words, they are men experiencing mid- to long-term negative energy balance.”
Dr. Berardi’s recommendation is commonly not what males anticipate.
If their consuming and train routines recommend they’re in a power adverse power state of affairs, he merely recommends they eat an additional wholesome snack or two a day.
“In situations like this, adding a couple hundred extra calories of high-quality protein and carbohydrate often fixes everything,” he says.
Those added energy may come from a pair scoops of whey protein combined in milk with a nut butter and banana sandwich on the aspect, he says.
Another favourite snack of Dr. Berardi’s: A bowl of steel-cut oats with protein powder, cacao powder, dates, uncooked nuts, and nut butter.
Keep in thoughts: Eating an excessive amount of (and gaining fats) can even have an effect on testosterone, as we’ll cowl quickly. Use our FREE vitamin calculator to make sure you’re consuming the correct quantity of energy and vitamins to assist hormone manufacturing.
Testosterone optimizer #2: Prioritize sleep.
Testosterone manufacturing has its personal circadian rhythm: It’s larger within the morning and decrease on the finish of the day.
As you sleep, ranges rise once more, peaking throughout your first section of fast eye motion. This might clarify why varied sleep problems—together with sleep apnea—are related to testosterone deficiency.7
A handful of small research have checked out what occurs to hormone ranges when males skimp on sleep.8 In certainly one of these research, individuals slept simply 5 hours an evening for eight days, leading to a ten to fifteen % drop in daytime testosterone ranges. 9
The correct quantity of sleep varies from one particular person to a different. However, in case you routinely get fewer than seven hours and wake feeling exhausted, it’s a very good wager you’re not getting sufficient. If you wake unrefreshed or wrestle to sleep soundly, our 14-day sleep plan might help.
Testosterone optimizer #3: Maintain wholesome physique fats ranges.
Body fats secretes aromatase, an enzyme that may convert some testosterone into estrogen.
According to some analysis, males categorized as chubby or overweight are likely to have barely larger ranges of estrogen, in addition to the stress hormone cortisol. 10 11
More analysis is required to know whether or not these barely larger estrogen ranges are sufficient to contribute to hypogonadism.
In the meantime, nonetheless, a wholesome physique composition is significant for total good well being and can also assist to optimize testosterone.
Keep in thoughts, as we stated above, that too little physique fats can even negatively have an effect on testosterone ranges. To guarantee your physique fats ranges are within the optimum zone, use our FREE physique fats calculator.
Testosterone optimizer #4: Get transferring.
Regular train is related to elevations in testosterone. It can even allow you to sleep extra restfully and hold physique fats in test.
Resistance coaching provides extra of a testosterone increase than endurance train. (Two to 3 periods per week is a superb benchmark.)
However, endurance train can even assist, offering you train on the proper depth, finds analysis. (That’s half-hour of rigorous exercise, 4 to 5 occasions per week.12)
Overtraining with out sufficient restoration can result in the alternative impact although, doubtlessly inflicting good points to plateau and suppressing testosterone.13
(See our FREE train library for 400+ professional how-to movies and a 14-day at-home exercise program.)
Testosterone optimizer #5: Consume a well-rounded, nutritious diet.
In addition to serving to you keep away from nutrient deficiencies that may drive down testosterone ranges, a nutritious diet protects your blood vessels.
That’s essential for getting erections.
A examine of 21,469 males discovered that those that consumed meals in keeping with the Mediterranean weight-reduction plan had a decrease threat of growing erectile dysfunction over ten years in comparison with males who didn’t observe the weight-reduction plan.14
“Mediterranean diets are also known to promote heart health,” says Dr. Asafu-Adjei.
The Mediterranean weight-reduction plan emphasizes fruit, greens, complete grains, nuts and legumes, and wholesome fat from meals like olive oil, eggs, and fatty fish. It de-emphasizes pink and processed meat, sugar-sweetened drinks, and sodium.
However, consuming patterns that middle on minimally processed complete meals seemingly provide the identical advantages.
Many fruits, veggies, and different minimally processed complete meals are wealthy sources of flavonoids, a plant chemical that helps to enhance blood move and testosterone manufacturing.
(This visible consuming information might help you select the very best meals in your physique.)
Testosterone optimizer #6: Avoid power emotional stress.
When you’re underneath stress, your physique produces cortisol and different hormones that put together you to battle, flee, or freeze. As these stress hormones flood your physique, they suppress the manufacturing of reproductive hormones like testosterone.15
This high-cortisol, low-testosterone phenomenon is a probable consequence of thousands and thousands of years of evolution.
Early people who had been extra desirous about mating than fleeing from sharp-clawed wild animals didn’t often stay lengthy sufficient to cross their genes to the subsequent era.
However, not all short-term stressors dampen testosterone. Some can increase it quickly, together with examination stress or train.16
So, goal for the stress candy spot the place you are feeling energized and engaged with life however not so busy and harried that you don’t have any time to calm down, sleep, or take pleasure in life.

Testosterone optimizer #7: Prevent zinc deficiency.
As an authorized well being coach, it’s out of your scope of follow to suggest dietary supplements to deal with a situation like hypogonadism.
In addition, the increase somebody may get from a complement pales compared to the six items of recommendation above, or to testosterone remedy.
With that essential caveat out of the way in which…
There is a correlation between low zinc consumption and low testosterone ranges.17 18
However, to profit from supplementation, somebody should really be poor within the mineral. Simply topping off somebody’s already ample zinc shops seemingly received’t result in a testosterone increase, and should even trigger hurt.
Checking for and treating a mineral deficiency requires the experience of somebody educated in medical vitamin remedy. If you lack this coaching, encourage purchasers with low testosterone to speak to their healthcare professionals about whether or not a zinc complement may assist.
Use the Deep Health lens
Let’s circle again to Dr. Berardi’s speculation, first talked about initially of this story:
Some evolutionary biologists have certainly theorized that males developed to have larger testosterone ranges once they’re youthful (to encourage mating) and decrease ranges once they’re older (to encourage parenting).19
However, that is extra of a idea than a certainty.
What we will say with certainty is that this: There’s no one-size-fits-all protocol for wholesome testosterone ranges.
When testosterone drops after center age, some males really feel awful.
Even once they do every little thing proper within the life-style division—exercising, consuming a nutritious diet, sleeping sufficient, and so forth—they’re unable to lift testosterone into the traditional vary. For these males, a healthcare skilled, thorough analysis, and, if warranted, testosterone remedy might be life-changing.
At the identical time, loads of different males proceed to thrive nicely into (and previous!) center age.
Sure, they might be unable to pack on muscle like they used to. But, in the event that they’re paying consideration, suggests Dr. Berardi, they could discover different pluses. Maybe they’re extra affected person, nurturing, and empathetic, for instance.
“Don’t get me wrong. I’d be very unhappy with an inappropriate or clinically significant lowering of my hormone levels,” says Dr. Berardi. “However, if I can stay in the normal range and symptom-free with good lifestyle practices, I don’t think I have too much to worry about.”
Dr. Berardi lately turned 50.
“I’m at this stage where I see an interesting fork in the road,” he stated.
“Will I gracefully accept aging and see this as a new season—or will I fight against it? I could color my hair, do hair transplants, top up my T levels, and get Botox injections. Or I could accept that there will be some eventual decline and ask, ‘What am I getting in return?’”
