Longjack, maca and zinc for men: how they work in Eros Lift
Updated August 2026 · reviewed by the Eros Lift Research Team. We are an independent information resource, not a medical provider, and this article is educational rather than medical advice.
Longjack, maca and zinc are three of the most recognisable names in men’s vitality formulas, and all three sit at the heart of Eros Lift. This guide explains what each one is, the mechanism in plain language, sensible dosing context, and exactly what to look for on a label — so you can read any product, including ours, with clear eyes.
The three headline actives, in one place.
- Zinc
- An essential mineral that contributes to the maintenance of normal testosterone levels; Eros Lift provides 50 mg per serving.
- Longjack
- Also called tongkat ali; a Southeast Asian root traditionally used for men’s energy and stamina. Eros Lift provides 400 mg.
- Maca
- A Peruvian root traditionally taken for stamina and drive; 250 mg in Eros Lift.
- L-arginine
- An amino acid the body uses to make nitric oxide, involved in healthy circulation; 250 mg in Eros Lift.
- The takeaway
- They are traditionally used dietary ingredients, not a treatment for any condition, and work best alongside sleep, training and diet.
Reading a supplement label can feel like decoding a foreign language. The aim here is to make the headline ingredients in Eros Lift genuinely understandable — and to give you a checklist you can use on any bottle. For the lifestyle context, pair this with our guide to boosting male vitality naturally.
Zinc: the foundation mineral
Zinc is an essential trace mineral, meaning your body cannot make it and must get it from food or supplements. In men’s health it is best known for one authorised role: it contributes to the maintenance of normal testosterone levels in the blood. It also supports normal fertility and reproduction, normal immune function and normal metabolism of macronutrients. Because zinc is lost through sweat and is not always plentiful in modern diets, many active men run low — which is why it is a foundation ingredient rather than an afterthought. Eros Lift delivers 50 mg per two-tablet serving.
Where zinc comes from
Food sources include oysters (by far the richest), red meat, poultry and pumpkin seeds. Fittingly, oyster extract is one of the marine ingredients in the Eros Lift blend — which is also why the product carries a shellfish allergen statement.
Longjack (tongkat ali): the traditional men’s root
Longjack, known botanically as Eurycoma longifolia and popularly as tongkat ali, is a flowering plant native to Southeast Asia whose root has been used for centuries in traditional preparations aimed at men’s energy, stamina and vitality. It is one of the most researched and most recognisable botanicals in the category. In modern formulas it is valued as a general adaptogenic tonic; Eros Lift provides a substantial 400 mg per serving, making it the single largest named botanical on the label.

Maca: the Andean stamina root
Maca (Lepidium meyenii) is a root vegetable grown high in the Peruvian Andes and eaten as a food for generations. As a supplement it is a food-grade adaptogen traditionally taken to support stamina, drive and everyday energy. It pairs naturally with longjack and zinc, rounding out the “energy and vitality” side of a men’s blend. Eros Lift includes 250 mg per serving.
L-arginine: the circulation amino acid
L-arginine is an amino acid the body uses to produce nitric oxide, a signalling molecule involved in normal blood-vessel function and healthy circulation. Because good circulation underpins so much of physical performance, L-arginine is a staple in performance-minded formulas. Eros Lift provides 250 mg, sitting alongside the botanicals rather than replacing them. The pathway behind that ingredient, and what the trials actually measured, is covered at length in L-arginine for men and nitric oxide.
How the actives compare
This table lines up the headline ingredients so you can see, at a glance, what each is and how much Eros Lift provides.

All three, in two tablets

Order Eros Lift — from $49/bottleWhat else is in the blend?
Beyond the headline four, Eros Lift rounds out its 745 mg proprietary blend with traditional men’s botanicals — tribulus terrestris, muira puama, catuaba, sarsaparilla, oat straw, cayenne, Chinese licorice, astragalus and nettle — plus the mineral boron and oyster extract. Each has a long history in tonic preparations, and together they give the formula its traditional, botanical character. You can read every ingredient, transcribed from the panel, in the ingredients section and see the full Supplement Facts. For how this formula sits against the wider category, see our guide to the best supplements for men. If you are choosing between the two headline botanicals, we set them against each other in longjack vs maca for vitality.
