Maxorin Ingredients: What Each Capsule Contains

Maxorin has eight named ingredients in each capsule. Two have printed amounts: vitamin B3 (niacin) at 20 mg and zinc at 11 mg. The other six share a 570 mg proprietary blend.

The blend holds L-citrulline, L-carnitine, pine bark extract, maca root extract, grape skin extract and saffron extract. They appear in that order on the Supplement Facts panel.

L-citrulline is an amino acid found in watermelon. The kidneys turn it into L-arginine, which blood-vessel linings use to make nitric oxide. Being first on the list means it is the heaviest part of the blend.

In 20 healthy volunteers, oral citrulline raised blood arginine better than arginine itself (Schwedhelm et al., 2008). In 24 men with mild erection problems, 1.5 g a day for a month improved a hardness score in 50% of them, versus 8% on placebo (Cormio et al., 2011). That trial was small and single-blind. More detail is in L-citrulline and nitric oxide explained.

L-carnitine carries fats into the mitochondria, the parts of cells that burn fuel for energy.

In 120 men aged 60 to 74, a daily mix of 2 g propionyl-L-carnitine and 2 g acetyl-L-carnitine for 6 months improved erectile scores (Cavallini et al., 2004). Studies in general have used 0.25 to 6 g a day (NIH ODS, Carnitine). In Maxorin, carnitine is second in the blend, so it can be at most 285 mg.

This extract comes from the bark of the French maritime pine, Pinus pinaster. It is rich in procyanidins, plant compounds linked to blood-vessel health.

In that study, 40 men took 1.7 g of L-arginine a day, then added 80 to 120 mg of pine bark extract (Stanislavov & Nikolova, 2003). There was no placebo group. Memorial Sloan Kettering rates the evidence as limited and notes it may raise bleeding risk with blood thinners (MSKCC, Pine Bark Extract). Maxorin can hold up to 190 mg.

Maca, Lepidium meyenii, is a root vegetable grown high in the Peruvian Andes. In supplements, it is linked with sexual desire.

In 57 healthy men, 1.5 or 3 g a day for 12 weeks improved self-rated desire, and testosterone did not change (Gonzales et al., 2002). A review of four small trials using 1.5 to 3.5 g a day called the evidence limited (Shin et al., 2010). Maca is fourth in the Maxorin blend, so it can weigh at most 142 mg.

Grape skin extract comes from Vitis vinifera, the wine grape. Grape skins carry polyphenols, including resveratrol.

In 19 adults, single doses of 30 to 270 mg of pure resveratrol improved artery widening, with more effect at higher doses (Wong et al., 2011). That study used pure resveratrol, not grape skin. The Maxorin label does not say how much resveratrol its extract contains. The extract itself can be at most 114 mg.

Saffron is made from the red stigmas of the Crocus sativus flower. It has a small body of research in men.

Across six small trials using 30 to 60 mg a day, saffron modestly improved erectile function scores, and side effects were mild (Maleki-Saghooni et al., 2018). Saffron sits last in the Maxorin blend. That caps it at 95 mg, so a studied amount could fit, though the real figure is not printed.

Niacin is a B vitamin your cells use to turn food into energy. Men need 16 mg a day, so 20 mg equals 125% of the Daily Value. The upper limit from supplements is 35 mg a day (NIH ODS, Niacin).

Flushing, a warm and itchy redness of the skin, usually starts at 30 to 50 mg or more. If you also take a B-complex or multivitamin, add up the niacin. The numbers are explained in zinc and niacin: what the numbers mean.

Zinc is a mineral your body needs for normal testosterone and sperm production. Men need 11 mg a day, so one capsule gives 100% of the Daily Value. The adult upper limit is 40 mg a day (NIH ODS, Zinc).

Maxorin uses zinc oxide, a common and stable form. The NIH notes zinc oxide is absorbed at about 50%. Zinc supports normal production; it does not push testosterone above normal.

Four other ingredients make up the capsule and help it hold together.

The label lists no caffeine, sugar, gelatin or artificial color. For how to take the capsule, see how to take Maxorin.

Some blend ingredients cannot reach the doses used in research. The whole 570 mg blend is about 38% of the 1.5 g of citrulline tested in men. Maca and carnitine caps sit far below their tested doses.

Two ingredients could fit. Saffron and pine bark were studied at amounts below their label ceilings. A lower dose is not proof the formula fails, but it is not the dose that was tested. Safety notes for each ingredient are on Maxorin side effects.
