Pine Pollen and Zinc (What Each One Brings to a Testosterone Stack)

Pine pollen and zinc turn up together in a lot of men's testosterone stacks, usually on the advice of a training partner or a long Reddit thread. Zinc has the older research behind it, going back to blood tests on men in the 1990s. Pine pollen has testosterone of its own (first isolated from Scots pine pollen in 1971) and two recent pilot studies in men. It also carries zinc, which most men stacking the pair never hear about.

Why men pair pine pollen and zinc

Zinc is the mineral most often linked to testosterone in men's blood work, and pine pollen is the plant most often linked to testosterone in men's routines. Men stacking want the mineral covered and the plant in the mix. The form of pine pollen you pick changes how much of the plant you get, which we come back to below.

If you're new to the plant itself, start with our complete guide to pine pollen, which covers where it comes from and how it has been eaten in China and Korea for centuries.

Zinc and testosterone in the research

The study men cite most is Prasad and colleagues, published in the journal Nutrition in 1996. It had three parts.

• In 40 healthy men aged 20 to 80, serum testosterone tracked zinc levels inside their white blood cells (r = 0.43 for lymphocyte zinc).
• Four healthy young men, average age 27.5, ate a zinc-restricted diet for 20 weeks. Their testosterone fell from 39.9 to 10.6 nmol/L.
• Nine older men, average age 64, who were marginally low in zinc took zinc gluconate (459 µmol a day, about 30 mg of zinc) for 3 to 6 months. Their testosterone went from 8.3 to 16.0 nmol/L, close to double.

The pattern the authors drew from it is that zinc status and testosterone move together in normal men, and the clearest swings came in men whose zinc was low to begin with. The US National Institutes of Health puts the daily zinc target for adult men at 11 mg, with an upper limit of 40 mg a day from food and supplements combined. Three ounces of farmed raw oysters carry about 32 mg. The same weight of roast beef sirloin carries 3.8 mg.

According to the NIH, the body absorbs anywhere from 5% to over 50% of the zinc in food, because phytates in beans, nuts and whole grains bind it in the gut.

Does pine pollen contain zinc?

Yes. Three separate lab analyses have found zinc in pine pollen.

In 2021, Erdyneeva and colleagues at the Baikal Institute of Nature Management in Russia measured the pollen of Scots pine (Pinus sylvestris) and Siberian dwarf pine (Pinus pumila). They found zinc at 44 to 54 mg per kg, alongside potassium at 11,493 to 12,942 mg per kg, magnesium at 925 to 1,045 mg per kg and manganese at 65 to 155 mg per kg. Total ash, the mineral part left after the pollen is burned, came to 2.68 to 3.22% of its weight.

A 2025 study from Hebei University of Science and Technology in China (Liu and colleagues) ran pine pollen through ICP-MS for 18 elements and named six as the main ones: sodium, magnesium, potassium, calcium, iron and zinc. A 1992 Korean analysis (Hye-ja Kim) of Pinus densiflora and Pinus rigida pollen also reported zinc among its main minerals.

So pine pollen brings a spread of minerals with zinc in it. Men who stack the two give each its own job. Zinc covers the mineral dose. Pine pollen brings the plant, with its own minerals and its own plant testosterone.

What the pine pollen studies in men measured

Two pilot studies led by Wolkodoff have tested a pine pollen tincture in men. In the 2024 study, 10 men aged 47 to 78 took the 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 mood) rose from 23.9 to 31.7.

The 2025 pilot followed 11 men aged 25 to 50, also for 8 weeks. Free testosterone, the part not bound to proteins in the blood, went from 10.48 to 11.72 ng/dL, and SHBG (the protein that binds testosterone) fell from 29.1 to 27.4 nmol/L.

Men taking pine pollen every day describe it in plainer words. The reports that come up most often are stronger morning wood and more drive. For the full write-up of both trials, see our article on pine pollen testosterone and the two studies in men.

Why the spagyric part counts for minerals

Most pine pollen tinctures are alcohol extracts. Alcohol pulls out plant compounds well, and minerals stay largely behind in the spent pollen, which usually gets thrown away. That 2.68 to 3.22% ash from the Baikal study is exactly the part a plain tincture leaves on the filter.

A spagyric tincture is made in two steps. The pollen is extracted first. Then the leftover pollen is taken down to its mineral salts, and those minerals are returned to the liquid. Zinc, potassium, magnesium and the rest of the pollen's minerals end up in the bottle with the extract, so the whole plant is in there.

Mara's Pine Pollen is made this way from wild-harvested, cracked-cell Pinus radiata pollen. Cracked cell means the pollen's tough outer wall has been broken open before extraction. It comes in a 50 ml dropper bottle of dark Miron glass, which keeps light off the liquid. It tastes soft and lightly earthy, with a faint sweetness.

How men take the two together

The two don't need to be timed against each other. A simple way to run them:

1. Zinc goes in with a meal, usually lunch or dinner. On an empty stomach a zinc tablet leaves plenty of men queasy, and food fixes that. Keep it at least a couple of hours apart from an iron supplement of 25 mg or more, since the NIH notes the two compete for absorption when taken together.
2. Pine pollen goes in at 1 to 2 droppers a day. Hold it under your tongue for 20 to 30 seconds and swallow, or stir it into water or juice.
3. Keep the zinc dose and your diet together under the NIH's 40 mg upper limit. A man who eats oysters twice a week already gets a big share from food.

At that rate one bottle lasts 30 to 50 days, and it fits in a gym bag next to the zinc.

Pine Pollen considerations

The recommendation on the product page: "Contains alcohol. If you're pregnant, nursing or taking medication, ask your doctor before using it."

Questions men ask about pine pollen and zinc

Can I take pine pollen and zinc at the same time?

Yes. Men commonly take zinc with a meal and pine pollen under the tongue or in water at another point in the day, and nothing in the routine requires spacing them apart.

How much zinc is in pine pollen?

A 2021 analysis of Scots pine and Siberian dwarf pine pollen measured 44 to 54 mg of zinc per kg. Men stacking for testosterone pair it with a zinc tablet for the full mineral dose.

What did the Prasad zinc and testosterone study find?

In nine marginally zinc-deficient men averaging 64, about 30 mg of zinc a day for 3 to 6 months took testosterone from 8.3 to 16.0 nmol/L.

Does a spagyric tincture keep pine pollen's minerals?

Yes. The minerals left in the pollen after extraction are returned to the liquid, so the zinc, magnesium and potassium the pollen carries end up in the bottle.
