Knowing what's inside a supplement is the most important due diligence step before buying. In this guide we provide a thorough, science-based analysis of every Intimax ingredient — covering what it does, what the research shows, and how it contributes to male vitality.

| L-Arginine | Nitric oxide & blood flow | ✅ Strong |
| L-Citrulline | Nitric oxide (more bioavailable) | ✅ Strong |
| Maca Root | Libido, energy, endurance | ✅ Moderate–Strong |
| Tongkat Ali (Longjack) | Testosterone, stamina | ✅ Moderate |
| Tribulus Terrestris | Libido, hormone support | ⚠️ Mixed |
| Zinc | Testosterone production | ✅ Strong (for deficient men) |
| Muira Puama Bark | Libido, blood flow muscle | ⚠️ Moderate (traditional) |
| Catuaba | Sexual stimulation, energy | ⚠️ Moderate (traditional) |
| Guarana Seed Extract | Energy, endurance | ✅ Moderate |
| Pine Bark Extract | Nitric oxide, circulation | ✅ Moderate |
| Ginger Root | Circulation, absorption | ✅ Moderate |
L-Arginine is a semi-essential amino acid and the body's primary precursor to nitric oxide (NO). Nitric oxide is critical for vasodilation — the relaxation and widening of blood vessels that allows increased blood flow, including to the corpus cavernosum (the penile tissue responsible for erections).
Research: Multiple human clinical trials confirm L-Arginine supplementation can support blood flow and erectile function, particularly in men with mild-to-moderate ED. Effective doses in research range from 3–6g daily. The key question for Intimax is whether the dose in the formula reaches this therapeutic range — a detail consumers should verify on the product label.
Key benefit: This is the primary mechanism behind Intimax's circulation support — and it's one of the most scientifically validated approaches in male vitality supplementation.
L-Citrulline is a natural amino acid found in watermelon that converts to L-Arginine in the kidneys — and actually produces more sustained nitric oxide elevation than L-Arginine alone. Research shows it is better absorbed orally than direct L-Arginine supplementation.
The combination of L-Arginine and L-Citrulline in Intimax creates a synergistic effect on nitric oxide production, giving the formula a meaningful advantage over single-compound competitors. Clinical studies using L-Citrulline show improvements in erectile function scores and exercise performance.
Maca (Lepidium meyenii) is a Peruvian root vegetable used for centuries to enhance energy, fertility, and libido. Multiple human randomized controlled trials have confirmed that Maca significantly improves self-reported sexual desire and reduces sexual dysfunction — notably without directly altering testosterone levels.
This makes Maca particularly valuable in Intimax's formula: it addresses libido and subjective vitality through pathways independent of hormones, meaning men whose testosterone levels are normal can still benefit meaningfully. Effective doses studied range from 1.5–3g daily.
Tongkat Ali — also called Longjack — is one of the most researched herbal testosterone-support compounds. Studies show it may help raise free testosterone, reduce sex hormone binding globulin (SHBG), and improve sperm quality in men with diagnosed low testosterone or fertility concerns.
A 2012 study found that 200mg of Tongkat Ali daily for one month significantly improved testosterone levels in stressed, aging men. The effect is most pronounced in men with suboptimal testosterone baselines, making it a smart inclusion in a male vitality formula targeting men over 30.
Tribulus is one of the most widely used — and most debated — herbs in male supplements. Its testosterone-boosting reputation is overstated in marketing materials, with human clinical trials showing inconsistent results for testosterone elevation in healthy men. However, its support for libido and sexual satisfaction is better documented.
As a libido-focused ingredient rather than a testosterone booster, Tribulus earns its place in Intimax's formula, particularly in combination with the stronger hormonal support from Tongkat Ali and Zinc.
Zinc is an essential mineral required for hundreds of enzymatic reactions, including testosterone biosynthesis. Zinc deficiency — more common than most people realize — directly impairs testosterone production and sexual function. Supplementation in deficient men produces significant, measurable testosterone improvements.
Zinc also supports immune function, protein synthesis, and cellular recovery — making it a broadly valuable inclusion beyond just hormonal support.
Muira Puama is a Brazilian herb traditionally used as an aphrodisiac and nerve tonic. Often called the "potency wood" of the Amazon, it has been used for centuries in South American traditional medicine to address sexual dysfunction and low libido. It appears in Intimax's formula specifically for its proposed ability to support the corporal smooth muscle — the penile blood flow mechanism. Human data is limited but promising for libido improvement.
Catuaba is another Brazilian traditional herb used to enhance sexual stimulation and combat fatigue. It contains alkaloids that may stimulate the central nervous system and support sexual arousal. Guarana is a natural stimulant containing caffeine and theobromine — providing clean energy and endurance support without the crash of synthetic stimulants. It also contains antioxidants that support vascular health.
Pine Bark Extract (Pycnogenol) has been specifically studied for erectile dysfunction, with clinical trials showing significant improvements in erectile function when combined with L-Arginine. It enhances nitric oxide synthase activity, further amplifying the formula's circulation-support effect. Ginger Root supports healthy circulation and aids nutrient absorption, ensuring the other active ingredients are bioavailable and effective when consumed.
