How Does Pine Pollen Work? (What's Inside It and What Changed in Men)

Pine pollen is the yellow dust a pine tree lets go of for a few weeks every spring. Men who ask how does pine pollen work usually want three things answered: what's in it, how it gets from a bottle into your body, and what changed in the men who took it. The answers start inside a single grain, with plant androgens found in Scots pine pollen in 1971, and end with blood tests on 21 men in two pilot studies published in 2024 and 2025. For the full background on the plant, its history in China and Korea and how it's gathered, see our complete guide to pine pollen.

What does pine pollen come from?

Every pine tree carries two kinds of cones. The large woody ones you pick up off the ground are female. The male cones are small, soft and clustered at the tips of the branches, and in spring each one swells and splits open to release clouds of pollen.

Each grain has a body in the middle and two air-filled sacs on its sides. The sacs grow out of the grain's outer wall and add surface area without adding much weight, so the grain falls slowly and the wind carries it a long way to reach the female cones of other trees.

That grain is a male sex cell. Its job is to carry the tree's genetic material to a female cone and fertilize it. In China the pollen, 松花粉 (song hua fen), has been recorded in herbal texts since the Tang dynasty.

What's inside a grain of pine pollen

In 1971 three researchers, Šaden-Krehula, Tajić and Kolbah, published a short paper in the Swiss journal Experientia (volume 27, pages 108 to 109). They had tested pollen from Scots pine (Pinus sylvestris) and isolated three androgens from it: testosterone, epitestosterone and androstenedione. Androstenedione came out highest of the three, at 5.9 micrograms per 10 grams of pollen. Scots pine pollen was the first plant in which testosterone had been found.

The rest of the grain is food. A 1996 analysis by Zhao put the protein content at about 13%. The grain also carries amino acids, polysaccharides, minerals, phospholipids and polyphenols, which is the list the 2024 pilot study authors gave for their own extract.

Why the wall around each grain has to be cracked

A pollen grain spends days blowing around in wind, sun and rain before it lands, and its wall is built for that. The outer layer is sporopollenin, one of the toughest materials any plant makes.

In rat feeding studies, the intact wall limited how much of the grain was digested. Cracked-cell pollen has had the wall broken open before it's used. Every serious pine pollen product starts from cracked-cell pollen for that reason, and it's the first thing to check on a label.

How does pine pollen work in the body, from the dropper on?

Here is how pine pollen works in the body when you take it as a tincture. Powders and capsules go straight to the stomach. A tincture gives you another route. You hold 1 to 2 droppers under your tongue for 20 to 30 seconds, then swallow, and the liquid sits against the thin tissue under your tongue and around your mouth before it goes any further. The 2024 pilot study used exactly this route. Its authors describe their tincture as made for "oral delivery and absorption under the tongue."

Alcohol does the extracting before the bottle ever reaches you. It pulls more of the steroid and sterol fraction out of the cracked pollen than water does. A spagyric tincture goes one step further. After the pollen is extracted, the minerals left behind in the spent pollen are returned to the liquid, so the whole plant ends up in the bottle.

Mara's Pine Pollen

Mara's Pine Pollen is a spagyric tincture of wild-harvested, cracked-cell Pinus radiata pollen. The wall is broken before extraction, and the minerals are returned to the extract afterwards. Simple ingredients: premium quality extract.

The taste is soft and lightly earthy, with a faint sweetness. Take 1 to 2 droppers a day under the tongue for 20 to 30 seconds and swallow, or stir it into water, juice or a smoothie. At that dose a 50 ml bottle lasts 30 to 50 days, long enough to run an eight-week stretch like the men in the two pilot studies below, on two bottles.

It comes in dark Miron glass. Dark amber glass is a step in the right direction for keeping light off an extract, and Miron is the gold standard. It's what Mara uses.

How does pine pollen increase testosterone in men?

The 2024 study is the one most men have heard about. Neil Wolkodoff and colleagues gave 10 men aged 47 to 78 (average age 63) a pine pollen tincture made from Pinus massoniana, 1 mL a day split morning and evening, five days on and two days off, for eight weeks. It was published in the Annals of Clinical and Medical Case Reports, volume 14.

• Average total testosterone went from 362.5 to 448.4 ng/dL, a rise of 85.9 ng/dL.
• The qADAM score, a 10-question survey on energy, drive, strength, mood and erections, rose from 23.9 to 31.7.

The authors put the result down to plant compounds in the pollen with androgen-like activity.

The 2025 pilot, published in the same journal, followed 11 men aged 25 to 50 and added two markers. Free testosterone went from 10.48 to 11.72 ng/dL. SHBG (sex hormone binding globulin) fell from 29.1 to 27.4 nmol/L. According to MedlinePlus, the US National Library of Medicine's health site, SHBG is a protein made mostly in the liver that binds testosterone in the blood, and testosterone bound to it can't act on your tissues. In the 2025 men, SHBG went down and the unbound share of testosterone went up.

Put the two studies side by side and you get the closest thing to an answer on mechanism. In older men the total number moved. In younger men the binding protein dropped and more of their testosterone was free.

What men say they notice

Outside the lab, the reports from men who take pine pollen daily are plain. Stronger morning wood comes up first. More drive comes second, in bed and in getting up and getting on with the day. Both line up with what the qADAM asked the 2024 men about. For timing, training days and how men fit it into a week, read our post on pine pollen for men.

Pine Pollen considerations

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

Questions people ask

What is pine pollen made of?

Protein at about 13% (Zhao, 1996), plus amino acids, polysaccharides, minerals and plant androgens. Testosterone, epitestosterone and androstenedione were isolated from Scots pine pollen in 1971.

How long did the men in the studies take pine pollen?

Eight weeks in both pilots. The 2024 group's average total testosterone went from 362.5 to 448.4 ng/dL over that time.

Why take pine pollen as a tincture?

The tincture goes under the tongue for 20 to 30 seconds, the route the 2024 study used. Alcohol extracts the sterol fraction from the cracked pollen, and a spagyric tincture returns the minerals too.

What pine does Mara's pine pollen come from?

Wild-harvested Pinus radiata. The pollen is cracked-cell and bottled as a spagyric tincture in dark Miron glass.
