Spartamax Ingredients: What Each of the 7 Compounds Does, and What the Evidence Shows

The Spartamax formula is a seven-ingredient blend of one amino acid and six botanicals, all of them familiar to anyone who's browsed the men's supplement aisle. What makes this page necessary is what the vendor leaves out: the amounts. Below, each ingredient gets a plain-English explanation of what it is, why it's in a male vitality product, what human research shows at known doses, and what you'd want to know that the label doesn't say.

The Spartamax ingredient list

Label fact The vendor lists these seven actives, described as a "powerful blend of carefully selected ingredients designed to support arousal, drive, firmness and overall performance."

L-Arginine HCl

What it is. A semi-essential amino acid your body uses to make nitric oxide (NO), the molecule that tells blood vessels to relax and widen. The HCl form is simply arginine bound to hydrochloride for stability.

Why it's here. Erections, and to some extent exercise stamina, depend on NO-driven blood flow. Arginine is the direct raw material.

Independent evidence A 2019 meta-analysis of 10 trials found arginine (1.5–5 g/day) improved erectile function scores compared with placebo in men with mild to moderate ED. Below about 1.5 g, effects are hard to detect, partly because much oral arginine is broken down in the gut and liver before reaching the blood. That's why L-citrulline, which converts to arginine after absorption, has become the preferred choice in well-designed formulas.

Editorial A gummy cannot realistically hold 1.5 g of arginine alongside six other ingredients. Whatever amount is in Spartamax is very likely below the range studied for erectile function. It may still contribute, but treat it as a supporting player. Full article: L-arginine for men.

Tongkat Ali (Eurycoma longifolia)

What it is. The root of a Southeast Asian shrub, used traditionally in Malaysia and Indonesia. Its active compounds are quassinoids, mainly eurycomanone.

Why it's here. It's the category's leading botanical for testosterone support, and it also shows cortisol-lowering activity.

Independent evidence A 2017 systematic review of 11 clinical studies concluded Tongkat Ali showed "considerable effects" on male sexual health markers, while noting small sample sizes and variable quality. A 2013 study found 200 mg/day for 4 weeks reduced cortisol by 16% and increased testosterone by 37% in moderately stressed adults. Effects appear strongest in older men and those with low-normal testosterone; in healthy young men with normal levels, changes are small.

Editorial Two things determine whether Tongkat Ali does anything: dose (200–400 mg of extract) and standardization (a good extract specifies eurycomanone percentage, often 1–2%, or uses a 100:1 or 200:1 root-to-extract ratio). Spartamax states neither. Full article: Tongkat Ali benefits and evidence.

Maca root (Lepidium meyenii)

What it is. A cruciferous root vegetable from the Peruvian Andes, related to radish and turnip. Consumed as a food for centuries; sold as powder or extract.

Why it's here. Libido. Maca is the best-studied botanical for sexual desire specifically.

Independent evidence A systematic review found that four RCTs showed maca improved sexual desire compared with placebo, though the authors called the overall evidence "limited" due to trial size. A well-known 12-week trial found 1.5 g and 3 g per day both increased self-reported sexual desire from week 8 onward, with no change in testosterone or estradiol. That hormone-independence is interesting: maca seems to work through a pathway other than testosterone.

Editorial The studied doses are 1.5–3 grams a day. A whole gummy weighs about that much. Spartamax cannot contain a clinical dose of maca powder; it might contain a concentrated extract, but the vendor doesn't say. This is the ingredient where the dose gap probably matters most. Full article: Maca root and libido.

Ashwagandha (Withania somnifera)

What it is. An Ayurvedic adaptogen; root and sometimes leaf extract standardized to withanolides. Branded extracts like KSM-66 and Sensoril dominate the research.

Why it's here. Chronic stress raises cortisol, which suppresses testosterone and sabotages arousal. Ashwagandha is the best-evidenced botanical for reducing perceived stress and cortisol.

Independent evidence The NIH Office of Dietary Supplements summarizes multiple RCTs showing reduced stress and anxiety scores, typically at 240–600 mg/day of extract for 6–8 weeks. A 2019 crossover trial in overweight men aged 40–70 found 16 weeks of ashwagandha (600 mg/day KSM-66) raised testosterone by about 15% and DHEA-S by 18% versus placebo.

Editorial Ashwagandha is one ingredient that could plausibly reach an effective dose in a gummy, since 300 mg is physically feasible. Whether it does is, again, undisclosed. Safety notes: ashwagandha may raise thyroid hormone levels and has been linked to rare liver injury case reports; see the side effects page. Full article: Ashwagandha, stress, and testosterone.

Horny goat weed (Epimedium)

What it is. A genus of flowering plants used in traditional Chinese medicine. The compound of interest is icariin, a flavonoid.

Why it's here. Reputation, mostly. In laboratory studies icariin weakly inhibits PDE5, the same enzyme targeted by sildenafil and tadalafil, which has made it a fixture in male products.

Independent evidence The PDE5 inhibition is real but roughly 80 times weaker than sildenafil in vitro, and human trials are essentially absent. Rat studies show improved erectile function; that's where the evidence stops.

Editorial This is the weakest link in the formula from an evidence standpoint. It's not harmful at typical doses, but we wouldn't buy any product for its horny goat weed content. Full article: Horny goat weed and icariin.

Beet root

What it is. Beetroot powder or juice concentrate, rich in inorganic nitrate.

Why it's here. Nitrate is converted by mouth bacteria to nitrite, then to nitric oxide, a second NO pathway that doesn't depend on arginine and works especially well when oxygen is limited.

Independent evidence A meta-analysis of 16 trials found beetroot juice reduced systolic blood pressure by about 4.4 mmHg. Exercise performance improvements are well documented at 300–500 mg nitrate (roughly 5–10 g of beetroot powder or 250–500 ml of juice). Direct sexual-function data is thin, but the blood-flow mechanism is well established.

Editorial The nitrate content of beetroot varies enormously between products, and an unstated amount of unstandardized beet powder in a gummy is likely a small nitrate dose. Interesting as a concept, uncertain in practice. Full article: Beet root and nitric oxide.

Grape seed extract

What it is. An extract concentrated in oligomeric proanthocyanidins (OPCs), potent polyphenol antioxidants.

Why it's here. Nitric oxide is destroyed quickly by oxidative stress. Antioxidants that protect the endothelium (blood vessel lining) may help NO last longer. It's the "protect what you produce" logic.

Independent evidence A meta-analysis of 16 RCTs found grape seed extract modestly reduced systolic and diastolic blood pressure, especially in younger and obese participants, at doses of 150–300 mg. No trials on sexual function.

Editorial A sensible complementary ingredient; unlikely to be the reason anyone notices a difference. Full article: Grape seed extract and circulation.

Does the formula make sense as a whole?

Editorial Yes, more than most. The seven ingredients map onto three mechanisms without much redundancy:

• Blood flow: arginine (NOS pathway) + beet root (nitrate pathway) + grape seed (protect NO) + horny goat weed (slow cGMP breakdown, weakly)
• Hormonal / stress: Tongkat Ali + ashwagandha
• Desire: maca (+ ashwagandha's anxiolytic effect)

That's a more thoughtful architecture than the "throw in every aphrodisiac herb" approach. The how it works page explains each pathway. But architecture without doses is a blueprint, not a building.

What's missing from the formula

• Zinc. Cheap, well documented, and deficiency is common in older men and directly lowers testosterone.
• Vitamin D. Same story; low levels correlate with low testosterone and ED.
• L-citrulline. The better arginine. Most modern blood-flow formulas have switched.
• Standardization details. Not an ingredient, but its absence is the biggest gap of all.

The gummy constraint

A gummy typically weighs 2–4 grams total, and much of that is the gummy base: sugar or sugar alcohols, pectin or gelatin, citric acid, flavoring, and coloring. The room left for actives is usually under 1 gram per gummy, often well under. With seven actives to fit in, the average share per ingredient is likely in the tens to low hundreds of milligrams. That's compatible with meaningful doses of Tongkat Ali extract, ashwagandha extract, and grape seed extract; it's incompatible with clinical doses of arginine, maca, or beet root. This is the physics of the format, not a criticism unique to Spartamax; every multi-ingredient gummy faces it.
