Introduction to Nugenix and Alpha King

When it comes to testosterone boosters, Nugenix and Alpha King are two of the most popular names on the market. Both claim to increase testosterone levels and improve overall vitality and virility.

We'd like to give you a summary of each brand so you'll also be able to understand their potential value in your workout regimen. 

Overview of Nugenix

Nugenix is one of the most popular testosterone boosters on the market. It contains a blend of natural ingredients that are said to increase testosterone levels and improve overall physical performance.

Nugenix is available in both capsule and powder form, and the recommended dosage is three capsules per day or one scoop of the powder mixed with water twice daily. According to the manufacturer, Nugenix helps to improve energy, libido, and muscle mass, while also reducing fatigue and promoting better sleep.

Overall, Nugenix is a decent choice for those looking for a natural way to boost their testosterone levels, but it does not have the highest success rate. 

Overview of Alpha King

Alpha King is a testosterone booster manufactured by Force Factor. It contains a limited formula consisting of only four active ingredients, including AlphaFen, a proprietary form of Fenugreek seed extract.

Alpha King Supreme is an improved version of Alpha King that is considered more effective than Nugenix Ultimate Testosterone. It's manufactured under strict FDA guidelines, ensuring that safety is not an issue.

Additionally, Alpha King Supreme contains Ashwagandha, which is known to reduce stress levels and enhance physical performance.

Despite being a proprietary blend and containing only a limited number of ingredients, Alpha King Supreme is still a popular testosterone booster among fitness enthusiasts.


Both Nugenix and Alpha King contain various natural compounds on their ingredients list. These formulas are created to assist with the many symptoms caused by low testosterone, such as loss of libido and therefore erectile dysfunction (ED).(1)

With these powerful and natural ingredients, both Nugenix and Alpha King aim to boost testosterone levels and deliver a range of benefits to male users.

Nugenix Ingredients

Nugenix has a total of six ingredients, which makes it noticeably powerful as a t-booster. It's important to note that Nugenix is not FDA-approved nor has it undergone scientific testing. 

Some of these ingredients include the following:

  • Fenugreek Extract (600mg)
  • Zinc (1mg)
  • Vitamin B6 (2mg)
  • Vitamin B12 (2.4 mcg)
  • Boron (10mg)
  • L-Citrulline Malate (1125mg)
  • elevATP Blend (150mg)
  • Eurycoma Longifolia Extract (100mg)

This added compound of Boron has been proven to reduce inflammation and estradiol, all while increasing free testosterone by 5% and breaking the testosterone bond with the blood proteins.(2)

Note: This is a general list. There are further added vitamins and minerals (e.g. Coconut oil) added to each of the product options Nugenix offer. Carefully look at these if you decide to go with this particular brand.

Alpha King Ingredients

When it comes to the ingredients, Alpha King boasts of high-quality botanical ingredients that are carefully determined in specific quantities to boost testosterone levels in men.

The mixture includes traditional sexual health ingredients, such as the following:

  • AlphaFen™ Fenugreek Seed (400mg)
  • Tribulus Terrestris (150mg)
  • Black Maca Root Extract (100mg)
  • DIM - diindolylmethane (100mg)

  • Vitamin D (84mcg)
  • Vitamin K2 (50mcg)
  • Zinc (30mg)
  • Magnesium (100mg)
  • Ashwagandha Root Extract (25mg)
  • L-Citrulline (1500mg)

The inclusion of L-Citrulline in the formula supposedly allows for better blood flow and pumps, with improved levels of vascular health for men.(3) AstraGin,(4) which is based on ginseng, is also present in this blend to help with absorption.

Alpha King has an excellent formula, but it's limited compared to some of its competitors. Overall, it appears to be a natural and safe option for those looking to enhance their testosterone levels.


When it comes to benefits, both Nugenix and Alpha King have their own advantages. Nugenix claims to deliver a boost in free testosterone levels, which help with muscle building and increased energy. Alpha King, on the other hand, targets four primary benefits which include a boost in libido and desire, improved athletic performance, enhanced muscle growth, and increased energy levels.

While Nugenix is more focused on muscle building, Alpha King offers a more holistic approach to men's health.
