Morning Wood Supplement (What Men Take When It Stops Showing Up)

Most men start looking for a morning wood supplement the week they notice the alarm goes off and nothing else does. For years you woke up hard most mornings without giving it a thought. Now it shows up twice a week, or it has gone quiet altogether. Morning wood runs on two things, sleep and testosterone, and you have more say over both than you might think. Men who want it back tend to fix the habits first and then add a daily pine pollen tincture.

Morning wood meaning, in plain terms

The medical name is nocturnal penile tumescence. It means the erections you get in your sleep, and morning wood is the last one of the night, still there when you open your eyes. A man with normal erectile function has about 3 to 5 of these a night, and they cluster in REM sleep, the stage where you dream. Each one can last 30 to 60 minutes.

The morning wood cause is REM sleep plus testosterone

During the day, part of your brain stem keeps erections in check. In REM sleep those cells go quiet. The sex researcher John Bancroft proposed in 2005 that when the locus ceruleus stops firing in REM, the effects of testosterone are left free to produce an erection. Testosterone itself runs highest in the early morning, so the last REM period of the night lands at the point where your levels peak.

The clearest link between morning erections and testosterone comes from the European Male Ageing Study. In 2010, Frederick Wu and colleagues published results from 3,369 men aged 40 to 79 across eight European centres in the New England Journal of Medicine. Of the symptoms they studied, only three sexual ones tracked together with falling testosterone: fewer morning erections, fewer sexual thoughts and erectile dysfunction. The authors drew the line at total testosterone under 11 nmol/L (3.2 ng/mL) with free testosterone under 220 pmol/L.

Put plainly, when morning wood fades, testosterone is one of the first numbers men look at.

Why don't I get morning wood anymore?

Age is part of it. In 1988, Raul Schiavi and Patricia Schreiner-Engel recorded sleep erections in healthy men of different ages and found that both how often they came and how long they lasted fell steadily with age, even when sleep itself was similar.

Testosterone drifts down at the same time. The European Male Ageing Study followed 2,395 men for an average of 4.4 years (Camacho and colleagues, 2013), and free testosterone fell by an average of 3.83 pmol/L a year.

Age is slow, though. If morning wood dropped off over a few months, look first at the habits below.

What you can change this month

Sleep

At the University of Chicago, Rachel Leproult and Eve Van Cauter had 10 men with an average age of 24 sleep under 5 hours a night for a week. Their daytime testosterone fell 10 to 15%, the drop you would expect from 10 to 15 years of ageing (JAMA, 2011). Fewer hours in bed also means fewer REM periods, and REM is when sleep erections happen.

Lift something heavy

Squats raised testosterone in men around 30 and men around 62 in a 1998 study by William Kraemer and colleagues in the European Journal of Applied Physiology. Eight younger men and nine older men did four sets of 10-rep squats, and total and free testosterone rose after the session in both groups.

Watch the evening drinks

A 2013 review from the London Sleep Centre (Ebrahim and colleagues) pooled 20 studies on alcohol and sleep. At every dose, alcohol pushed back the first REM period of the night. At high doses it cut REM in the first half of the night, and total REM fell at moderate and high doses.

Body fat

In the same 2013 follow-up of the European Male Ageing Study, men who lost weight saw testosterone rise in proportion, and men who gained saw it fall. Free testosterone moved most in men whose weight changed by 15% or more.

What men look for in a morning wood supplement

The shelves are full of horny goat weed, L-arginine and blends with names built around wood. Men who think it through ask for three things. They want an ingredient with a real tie to testosterone, numbers measured in men, and a form they'll keep taking every morning without it turning into a chore.

Pine pollen meets all three, and it's the one men pick.

Why men pick pine pollen

Pine pollen was the first plant in which testosterone was ever found. In 1971, Šaden-Krehula and colleagues isolated testosterone, epitestosterone and androstenedione from Scots pine pollen. The full background is in our complete guide to pine pollen.

Two pilot studies have since measured it in men. In the 2024 pilot by Wolkodoff and colleagues, 10 men aged 47 to 78 took a pine pollen tincture for 8 weeks. Their average total testosterone went from 362.5 to 448.4 ng/dL, and their qADAM scores (a questionnaire on drive, energy and the other changes men notice when testosterone runs low) rose from 23.9 to 31.7. In the 2025 pilot, 11 men aged 25 to 50 saw free testosterone go from 10.48 to 11.72 ng/dL, while SHBG, the protein that binds testosterone and keeps it out of use, fell from 29.1 to 27.4 nmol/L.

Ask men who take it daily what changed and two answers come up again and again. They report stronger morning wood, and they report more drive. For a closer look at the tincture itself, read our pine pollen review.

Mara's Pine Pollen, and why the tincture

Mara's Pine Pollen is wild-harvested Pinus radiata pollen. The pollen wall is tough, so ours is cracked cell, with the wall broken open before extraction. Then it's made spagyric: the pollen is extracted, the minerals left behind are returned to the liquid, and the whole plant ends up in the bottle.

The bottle matters too. Dark amber glass is a step in the right direction, but the gold standard is dark Miron glass, which keeps light off the extract for the life of the bottle, and it's what Mara uses.

A tincture also fits a man's morning. One dropper under the tongue while the kettle boils, hold it 20 to 30 seconds, swallow, done. It tastes soft and lightly earthy, with a faint sweetness. Most men take 1 to 2 droppers a day, so a 50 ml bottle lasts 30 to 50 days.

The goal is the morning you used to have. You wake up, you feel like yourself again, and you don't have to wonder about it.

Pine Pollen considerations

Contains alcohol. If you're pregnant, nursing or taking medication, ask your doctor before using it.

Questions men ask about morning wood

Is it normal to get less morning wood as you get older?

Yes. Sleep lab work by Schiavi and Schreiner-Engel (1988) found sleep erections came less often and lasted less time with each decade in healthy men.

Does morning wood mean high testosterone?

In the European Male Ageing Study, fewer morning erections was one of three sexual symptoms tied to low testosterone in men aged 40 to 79. Regular morning wood is one of the signs men read as their levels holding up.

How long did the pine pollen studies run?

Both pilots ran 8 weeks, with blood work at the start and the end, so men give it two bottles before judging it.

Which pine does Mara's pine pollen come from?

Wild-harvested Pinus radiata, cracked cell and made into a spagyric tincture in dark Miron glass.
