Vitality Benefits

The Vitality Testo Booster is one of the most popular products in the supplement market due to its unique ability to naturally boost testosterone levels while providing a mirage of auxiliary health benefits. 

Below we dive into the benefits that accompany this products’ use:

  • Increases Bioactive Testosterone Levels: Low testosterone levels are the most common reason for decreased athletic performance, fatigue, depression, weight issues, stunted muscle growth, lost libidos, and overall poor health in males. This supplement boosts bioactive testosterone levels to flood the body with the hormone for optimal performance.
  • Controls & Regulates Estrogen  levels: Uncontrolled estrogen levels often cause testo levels to drop, hindering muscle growth and efficient muscle functionality. Strength Series regulates/controls estrogen production so testosterone can have a more solid stance in the body. This allows users to build muscle and lose fat simultaneously. High testo levels also support a healthy heart, blood sugar/pressure levels, stronger bones, better verbal memory, spatial abilities, libidos, and more.
  • Lowers Stress & Cortisol Levels: Cortisol hormones are compounds released into the bloodstream when the body and mind are stressed. High amounts of cortisol make weight loss difficult, causing unnecessary weight gain and fat retention/storage. This supplement naturally reduces the amount of cortisol in the body by using Ashwagandha.

    In addition to the rapid onset of these benefits following commencement of supplement use, we found that they can be achieved and experienced long-term through consistent/regular use.

Vitality Ingredients

The scientifically researched Strength Series formula contains 8 active components that work together seamlessly to produce potent effects. The extensive range of ingredients is present in clinically approved volumes to ensure that users receive noticeable results in the shortest time possible. 

The ingredients are derived from natural sources, lowering the possibility of side effects and increasing user compatibility rates. The premium ingredients in the formula form a synergistic barrier that protects Leydig cells that comprise testosterone production and fertility. 

The secret behind Strength Series' effectiveness is listed below:

  • Zinc: Zinc supports optimal fertility rates and testosterone and sperm production in males.

  • Organic Ashwagandha Extract: Ashwagandha is a versatile adaptogenic herb that alleviates stress-induced cortisol secretion and helps the brain and body function optimally.
  • Shilajit Extract: This extract improves vitality and increases both total and free testosterone levels.
  • Quercetin Dihydrate: Known as a vital micronutrient, Quercetin works as an antioxidant in body systems. It also protects Leydig cells to help the body create and produce testosterone and maintain fertility.
  • DIM (Diindolylmethane): DIM regulates estrogen metabolism and plays a vital role in gene expression in both men and women. It also positively affects muscle growth/recovery, sex drives, and moods.
  • L J100 (Standardized Eurycoma longifolia extract): Increases testosterone to cortisol ratios and improves lean body mass, muscle size, and strength.
  • Bioperine (Black Pepper Extract): Promotes thermogenesis for natural fat reduction and enhances bioavailability allowing nutrients to be absorbed more efficiently by the body.
  • Boron: Boron boosts free testosterone, reduces estrogen, improves magnesium absorption, and helps the body better utilize hormones.

In addition to the premium, scientifically-backed ingredient list, the supplement also contains no artificial sweeteners, coloring, or preservatives, which provide holistic effects that will benefit users long term, which we feel is an additional benefit on its own.
