Cyvita is one of the few male enhancement supplements that reached mainstream attention through television ads, promising “clinically proven” results for longer, stronger, and more frequent erections. It claims to outperform Viagra and testosterone, with a natural formula focused on circulation and stamina. But does Cyvita actually deliver — or is it another overhyped supplement?
Manufactured by Cyvita LLC, based in Reno, Nevada, the supplement has been sold for years through TV campaigns and its official website. However, Cyvita’s reputation online has been mixed. According to the Better Business Bureau, the brand has received numerous complaints — mostly related to its auto-shipping program and refund issues. Similarly, customers on Scambook and Amazon mention poor results and billing frustrations.
Despite the controversy, Cyvita continues to attract attention because its ingredient profile — particularly its dual-carnitine complex — has legitimate scientific interest. In this review, we’ll separate the marketing hype from the actual science and user evidence to determine whether Cyvita is worth trying in 2025.
What Does Cyvita Claim to Do?
According to its advertisements, Cyvita supports:
Firmer, more frequent erections (when sexually stimulated)
Improved energy and physical recovery
Enhanced blood flow and cardiovascular performance
Greater sexual stamina and vitality
These claims are bold, but not necessarily unrealistic — provided the active compounds are dosed properly. Let’s look at the science behind its key ingredients and how they might (or might not) support male performance.
Cyvita Formula Overview
Cyvita’s formula includes a handful of essential nutrients and amino-acid derivatives designed to boost blood flow and support nitric oxide production:
Vitamin C
Zinc
Epimedium sagittatum (Horny Goat Weed, standardized for 40% Icariin)
Glycine Propionyl-L-Carnitine (GPLC)
Acetyl-L-Carnitine (ALCAR)
The manufacturer claims each tablet contains about 2000 mg of carnitine compounds, although the exact ratio of GPLC to ALCAR remains proprietary. Both play roles in mitochondrial energy production and circulation, which may indirectly benefit erectile function.

Scientific Evidence Behind Cyvita Ingredients
While Cyvita itself has never been tested in peer-reviewed clinical trials, several of its components have well-documented effects on vascular health and sexual function. Let’s break them down individually.
1. Glycine Propionyl-L-Carnitine (GPLC)
GPLC is an esterified form of L-carnitine that enhances nitric oxide levels and improves blood flow. A study published in the Journal of the International Society of Sports Nutrition found that GPLC supplementation increased plasma nitrate/nitrite levels by over 30%, supporting its vasodilatory properties (PMID: 17136935).
In the context of male enhancement, improved blood flow may contribute to better erectile quality and stamina. Unlike pharmaceutical PDE5 inhibitors (like sildenafil), GPLC works through metabolic pathways, supporting long-term vascular health rather than inducing a direct erection.
2. Acetyl-L-Carnitine (ALCAR)
ALCAR is a neuroprotective amino acid derivative that supports mitochondrial energy metabolism and nerve health. Clinical research has shown that ALCAR may improve erectile function in men with age-related decline when combined with L-arginine (PMID: 15538950).
Additionally, a randomized controlled trial published in Urology demonstrated that ALCAR improved sperm motility and sexual well-being in older men, suggesting potential fertility benefits (PMID: 17034903).
3. Epimedium sagittatum (Icariin)
Icariin — the active compound in Horny Goat Weed — acts as a mild PDE5 inhibitor, similar in mechanism to Viagra. It enhances nitric oxide synthesis and cGMP levels in penile tissue, promoting stronger erections. In vitro studies confirm its PDE5-suppressing ability (PMID: 19349515), although its bioavailability in humans remains relatively low.
When combined with circulation-enhancing nutrients like carnitines, however, the synergy can improve overall sexual performance.
4. Zinc and Vitamin C
Zinc plays a crucial role in testosterone production and sperm health. Deficiency in zinc is directly associated with reduced androgen levels and impaired sexual function (PMID: 8875519). Vitamin C, meanwhile, supports nitric oxide preservation and protects endothelial cells from oxidative damage (PMID: 16408761).
Together, these nutrients provide foundational antioxidant and hormonal support that complement Cyvita’s core formula.
How Does Cyvita Work Compared to Viagra?
Cyvita does not act as a prescription-grade PDE5 inhibitor. Instead, it promotes vascular support and nitric oxide balance over time. While Viagra provides near-instant results by chemically inhibiting PDE5 enzymes, Cyvita’s effects develop gradually through improved metabolism, cellular energy, and endothelial function. Most users would need 3–6 weeks of consistent use to see meaningful results.
Scientific Summary: The carnitine and icariin combination in Cyvita may support better erectile quality through enhanced nitric oxide and cellular energy, but evidence is indirect and based on ingredient-level studies rather than Cyvita-specific trials.
Real-World Results and Customer Feedback
Based on user testimonials and third-party review sites, Cyvita’s results are highly variable. Some men report improved stamina and erection quality after several weeks, while others notice no change. The inconsistency may stem from proprietary dosages and individual response differences.
Unfortunately, Cyvita’s auto-billing issues have damaged its credibility. Dozens of customers on BBB and Scambook complained of recurring charges even after cancellation. This does not necessarily reflect on the formula itself, but on the company’s marketing practices.
Possible Side Effects
Cyvita’s formula is generally safe, as its ingredients are naturally occurring amino acids and plant extracts. Reported side effects are minimal and may include:
Mild stomach upset (if taken on an empty stomach)
Headache (rare, from nitric oxide changes)
Insomnia (from increased energy metabolism)
Unlike stimulant-based supplements, Cyvita is free of caffeine or yohimbe. However, those with heart disease or on blood-thinning medication should seek medical advice before use.
Dosage & Use
The manufacturer recommends taking 2–6 tablets daily on an empty stomach. Two tablets are suggested for daily maintenance, while 6 tablets may be taken prior to sexual activity for maximum effect. As with any supplement, consistency matters — the compounds must accumulate in the body to exert measurable effects.
Price & Purchase Information
Cyvita is available only through its official website. The company often promotes “trial offers,” but these are linked to an auto-renewal subscription of about $59.40/month unless canceled within 12 days. Always read the fine print before signing up.
Currently, Cyvita is not accredited by the Better Business Bureau and does not offer a clear money-back guarantee. For those concerned with transparency, alternatives like VigRX Plus or ProSolution Pills provide better consumer protection policies.
Final Verdict – Is Cyvita Worth Trying?
Cyvita combines legitimate science with questionable marketing. Its active ingredients — particularly GPLC, ALCAR, and Icariin — are backed by clinical research for vascular and sexual health. However, the lack of published trials on Cyvita itself, undisclosed dosages, and an unreliable billing system weaken its credibility.
In our opinion, Cyvita may provide mild improvements in energy, circulation, and stamina for some men, especially those deficient in carnitine. But for stronger, clinically validated results, formulas like ProSolution Pills or VigRX Plus are superior alternatives.
Our Rating: ⭐⭐☆☆☆ (2.5 / 5)
Best For: Men seeking a mild nitric oxide and energy boost without stimulants. Not Recommended For: Anyone expecting fast, Viagra-like results or guaranteed refunds.
