KING ingredient breakdown:


An ayurvedic herb renowned for millennia, Ashwagandha has been touted for its ability to fight stress and reduce cortisol levels, as well as countless other benefits to general health and wellness. This adaptogen also, however, has been shown to boost testosterone levels and improve fertility in males. KING contains 600mg of Ashwagandha per six capsule serving.

Tribulus Terrestris

First hailed by Bulgarian Olympic athletes decades ago, Tribulus Terrestris is a natural botanical extract that has had buzz in bodybuilding and weightlifting circles for years. Tribulus enhances the KING formula by stimulating the production of lutenizing hormone (LH) in turn potentially leading to increased testosterone production. Each serving of KING includes a potent 600mg of Tribulus Terrestris, standardized for a minimum of 45% steroidal saponins.


Derived from Indian and African plants, Fenugreek is a natural herb popular in holistic medicine for hundreds of years. Containing furostanolic saponins, Fenugreek has been shown in studies to increase testosterone production resultingly improving strength and body composition while also boosting libido. Six capsules of KING contain 500mg of Fenugreek seed extract, standardized for a minimum of 50% steroidal saponins.


An essential mineral, hard-training athletes tend to be zinc-deficient. Proper supplementation with this “master mineral” can boost immunity, thyroid function and protein synthesis while also raising serum blood testosterone levels in those displaying even a mild zinc deficiency. A robust 40mg of zinc can be found in every serving of KING, alongside its brother overlooked anabolic mineral—Magnesium.


An oft-overlooked “wonder mineral” Magnesium plays a critical role in just about every muscle-building and athletic performance process occurring in the human machine. From protein synthesis to bone density to muscle and nerve function to relaxation, Magnesium is a necessity, and most hard-training athletes are deficient. Supplementing with Magnesium can address these deficiencies that may translate to optimized androgen production. Every serving of KING contains 300mg of Magnesium Citrate, a form celebrated for its many nervous system health benefits. Anecdotally, taken together, zinc and magnesium are touted for their ability to improve sleep quality and restorative REM sleep.

Vitamin D3

The sunshine vitamin, Vitamin D3 is critical in enhancing immunity, bone strength and improving mood. But yet another micronutrient in which many athletes tend to be deficient. Higher dosages of Vitamin D3 can address these deficiencies and promote testosterone production. KING contains a whopping 3000iu dose of D3 in every six capsule serving.


Another underrated anabolic mineral, Boron represents one half of the “Utilization & Uptake Complex” designed to amplify the potency of KING, helping it reach its maximum muscle-building impact via natural pathways. Boron helps to unlock free testosterone, integral to capitalizing on any increase in total testosterone production facilitated via the herbs, vitamins and minerals in the KING formula.


The patented black pepper extract, Bioperine. Known as a powerful “bioenhancer”, piper nigrum has myriad positive effects on everything from metabolism to mental acuity but is most highly regarded for its ability to greatly increase nutrient absorption. Adding Bioperine to the KING formula ensures that you are maximizing your test-boosting bang for your hard-earned buck, getting the most kick out of the seven other strong constituents found in six capsules of KING.
