Why is it Important to Deal with Erectile Dysfunction (ED)?

It is common. It is the first clinical manifestation of atherosclerosis which affects quality of life.

ED is common and affects everyday life. 50% of men experience ED between 40 and 70 years of age – in most cases (65%) in mild form.1

The ED is typically a warning sign of vascular disease (atherosclerosis). Penile arteries are smaller in diameter than atreries in the the heart / brain / limbs. At an early stage of atherosclerosis, the penile arteries are constricted when the blood supply of the other organs is still adequate.2 In clinical trials, erectile dysfunction precedes coronary artery disease (chest pain and heart attack) by 2-3 years on average. 3 In this respect, erectile dysfunction is the optimal stage for initiating therapy with the purpose of  preventing progression of arteriosclerosis.

Causes of Еrectile Dysfunction: Major Role of Аtherosclerosis

Atherosclerosis, stimulation disorder, stress

Atherosclerosis, is responsible for 50-80% of erectile dysfunction. In the early phase of atherosclerosis, NO is released in the endothelium  and determines endothelial function. 3.4

Erectile dysfunction can be caused by hormonal, neurological, vascular, psychological and other factors. 4.5

The Mechanism of Erection: the Key Role of Nitrogen Oxide (NO)

Brain stimulation, nerve stimulation, nitrogen oxide release

The erection cycle requires fine tuned co-operation between the brain, the artery wall and the enzymes.

  1. As a result of stimulation, the brain signals the enzyme eNOS (endothelial nitric oxide synthase) to produce more nitric oxide (NO).
  2. NO stimulates the production of guanyl cyclase enzyme (cGMP), which causes vascular smooth muscle relaxation, enabling erection.
  3. Phosphodiestherase-5 (PDE5) enzyme reduces cGMP levels, eliminating erection. 

The most important risk factors for ED are also the main risk factors for endothelial dysfunction, atherosclerosis, and reduced NO production: hypertension, high cholesterol, high blood sugar, obesity, smoking, aging.6-8 ED is probably an early indication of non-diagnosed diabetes. 9

What Can Men Do for Healthy Sexual Function?

Lifestyle, counseling, medicines / dietary supplements?

  • Lifestyle changes to improve the condition of blood vessels
  • Psychosexual counseling
  • Oral medicines, dietary supplements.
  • Injection treatment
  • Operation (penis implant) 5

Requirements for Drugs / Dietary Supplements Recommended to Improve Erectile Function

Proven, increase NO level, cardiovascular protection, no side effects

  • Have proven effects in appropriate clinical trials.
  • Increase NO production (this may affect the most common cause of the problem). 6
  • Reduce major risk factors for erectile dysfunction (blood pressure, cholesterol, blood sugar. 2-4, 9
  • No side effects or interaction with widely used drugs.

Male Enhancing Drugs and Vigor: Two different, Complementary Concepts

The active ingredients in Vigor improve erectile function naturally and enhance cardiovascular protection by increasing the NO level.

Vigor acts at the beginning, male enhancement drugs act at the end of the process

A Vigor természetes módón javíthatja a merevedési funkciót

Male enhancement drugs (PDE-5 inhibitors) inhibit the phasing out of smooth muscle relaxation. A part of the smooth muscle relaxation leading to erection is retained, the cGMP saved can reach the level required for erection, but the drugs do not affect the cause, the reduced release of NO and the atherosclerosis. This is a non-physiological approach with significant side effects. 10

The active ingredients of Vigor naturally restore the ability of blood vessels to produce a spontaneous erection in response to sexual stimulation. Vigor acts on the cause of the problem (the inadequate synthesis of NO in mild ED). NO stimulates cGMP production in smooth muscle that increases penile blood flow through muscle relaxation

Male enhancement drugs work temporarily for planned events, while Vigor restores body’s own potential, and naturally ensures the possibility of spontaneous erection and vascular protection. 10-22

The PDE-5 inhibitors are ineffective in at least 30% of men with ED, 23 because selective blocking of normal hydrolysis of cGMP can only partially reverse the deficiency of the NO / cGMP pathway. Insufficient production of NO (caused by age or difeerent diseases / conditions) does not allow production of adequate level of  cGMP needed for the effects and benefits of PDE-5 inhibitors. For men with insufficient production of NO (a 50-year old man produces 50% of NO he used to produce at the age of 30), the active ingredients of Vigor can promote the effectiveness of PDE-5 inhibitors, so the two approaches can complement each other.

Active Ingredients in Vigor Capsules

Aminoacids required for NO production, Pycnogenol, Indian ginseng (ashwagandha)

  • L-Arginine: Amino acid essential for NO production. Immediately precedes NO in the metabolic chain. Our body is able to produce it, but with age, our production capacity is greatly reduced (85% lower in 60 years olds compared to than 20-30 year olds ) 11,12
  • L-citrulline: amino acid, permanently increases NO level. 13,14 In a clinical trial, L-citrulline alone improved the spotting function. 14
  • Pycnogenol: Provides complex protection for the cardiovascular system, 15 in combination with L-arginine spectacularly improves erectile function 16, 17
  • Ashwagandha (Indian ginseng): enhances libido and NO levels. 18-20
  • Zinc: Increases testosterone levels. 21
  • Selenium: primary antioxidant, helps to reduce the oxidative stress caused by cardiovascular risk factors. 22

Why do We Recommend Vigor Capsule?

Evidence-based, increases NO level, cardiovascular protection, no side effects

  • The right approach from the point of view of physiology: Increases NO level, ensures a healthy response to spontaneous stimulation.
  • Complex: Helps to produce NO in each step of the process 15-22
  • Proven: Its active ingredients  improved erectile function and risk factors for atherosclerosis as monotherapy or in combinations. 14, 16, 17
  • Quality: contains the brands used in clinical trials.

Ingredients in Vigor Capsule

Two capsules contain 500 mg L-arginine, 500 mg L-citrulline, 40 mg  Pycnogenol.

The active ingredient in a capsule is 250 mg  L-arginine HCl ( 206.7 mg L-arginine), 250 mg L-Citrullin, 20 mg Pycnogenol, 25 mg Indian ginseng (ashwagandha), 32.2 mg zinc citrate (10 mg zinc), 3.9 mg copper gluconate (1 mg copper), 37.5 mcg selenium (from selenium-rich yeast). In clinical trials, the best results were achieved with a ratio 1: 1 L-arginine:L-citrulline. 7

Who do we Recommend the Vigor Capsule?

All men over 40 years of age.

The early-onset therapy has two goals (both closely related to NO production): improving erectile function and reducing the risk factors of atherosclerosis and preventing complications (infarction, stroke).
