I’m always extra cautious when I see testosterone booster supplements with extremely clever marketing and big advertising campaigns.

And if you add in celebrity endorsements, it’s normally a sign that the company has spent more on marketing than the formula.

When we first spotted Alpha King online, it seemed to fit that category, but then we got some positive feedback from readers.

So we decided to research it a bit more and see how Alpha King compares to test boosters that we’ve researched and tested.

Here’s what we found.

What Is Alpha King Supreme?

Alpha King Supreme is a testosterone booster made by Force Factor. This supplement is designed to increase free testosterone production within weeks, giving you the muscle power and sex drive of a teenager on a hormone overdrive.

I know, we’re a little bit jealous of young men when it comes to testosterone.

Now, it’s not specifically marketed as a treatment for erectile dysfunction, but everything on the label suggests that you’ll be doing resistance training like The Rock and unleash your potential in the bedroom.

Let’s see how much of it is true.

Alpha King Supreme Benefits

The first thing I want to point out is that Force Factor has done the right thing by not hiding behind a proprietary blend.

The label lists everything and shows the exact amounts, and that’s important if you need to stack this with other products.

For testing purposes, we got a few clients to help out, and at least three of them said they had taken a before and after blood test that confirmed an increase in testosterone.

While none of them reported a major boost in sexual performance, they did find that it had an impact on their fitness journey.


Does Alpha King Supreme Have Any Downsides?

One downside of Alpha King Supreme is its insignificant effect on pumps.

Another thing worth noting is its big capsule size, so if you stack this with other supplements, swallowing can become quite tricky.

  • Some positive results were posted from men with low testosterone
  • The company doesn’t hide behind proprietary blends
  • It contains added vitamins D and K2 for immune benefits
  • It comes with a strong dose of zinc to support testosterone production
  • Has a limited effect from the blood flow ingredients
  • You’ll need to take three capsules for the full dosage


Alpha King Supplement Facts

I already mentioned that it’s great that Force Factor has listed out all the ingredients. I’ll go through them here with some information that our dietitian provided on each of them.

Vitamins D and K2: These should be a priority for all men as a study from the Department of Gastroenterology and Hepatology, Osaka University, indicates that they may directly impact immune, heart, and bone health [1].

Magnesium Stearate And Zinc: These minerals play a vital role in muscle function and testosterone production to build lean muscle mass [2] [3].

“Zinc deficiency can hinder testosterone production. Like magnesium, zinc is lost through sweat, so athletes and other people who sweat a lot are more likely to be deficient.”

- Michael Hull, Writer at

Ashwagandha Root Extract: Studies have shown that this herb may help especially overweight men to gain more control over testosterone levels [4].

Alphafen Fenugreek Seed Extract: Alpha King also contains some powdered fenugreek seeds, and our dietitian pointed us to a study that had good results with the same amount as Alpha King contains [5].

Black Maca Root: For this herb, we couldn’t find conclusive evidence that it would help with testosterone [6]; studies have shown mixed results for black maca root.

DIM (Diindolylmethane): This isn’t directly tied to testosterone production but rather reducing how much of it is transformed into estrogen [7].

Boron: This is another mineral that scientists have linked to testosterone, and it seems to have a strong dosage [8].

L-Citrulline: This is the ingredient in Alpha King that supposedly should bring on better blood flow and pumps [9].

AstraGin: Based on ginseng, the company claims that it will help your body absorb more L-citrulline.

The one thing we’re missing here is black pepper extract for enhanced bioavailability. It tends to help with absorbing the ingredients faster.

How Does It Work?

Alpha King Supreme works by preventing the transformation of too much testosterone into estrogen using ingredients that act as a testosterone booster and natural performance enhancer.

Our dietitian did confirm that most of the ingredients in the formula are scientifically proven.

And they are there in a good dose in the supplement as well to trigger increased T-levels.

Alpha King should also increase strength levels through better pumps, but that is one area where we didn't see the same results as we have with other supplement products.

How Does ​​Alpha King Compare To Other Supplements?

We compared Alpha King to other supplements like TestoFuel, Aphro-D, and TestoGen.

Compared to Testogen and TestoFuel, which offer 4 capsules per serving size, AlphaKing offers 6 capsules.

Both Alpha King and TestoFuel are testosterone enhancers that also help with anabolism.

The compounds of Alpha King, Testogen, and TestoFuel differ, except for Fenugreek, which is beneficial to physical performance, sex drive, and testosterone levels.

In our test, we measured higher T-levels with Alpha King, and our clients noted improvements in their libido, brain function, and weight management.

The results were not as good as expected. We have gained much more confidence in the similar products we've been testing, and the measured increases are much better.

Where Can You Buy Alpha King Supreme?

You can buy Alpha King Supreme on Amazon. However, the product is always out of stock whenever we check, which will make it difficult to maintain a constant supply.

We intended to test it for several more months but often didn’t have the option to order more.

Secondly, Alpha King is often only available from resellers. That leaves you open to getting a fake supplement. To prevent this, consider doing some research on the reseller to check on their reputability.

A good practice is to look for unbiased reviews from third-party review websites to get a good grasp on the seller's practices of selling the Alpha King Supreme supplement.

Other User Reviews

During our research, we also found some interesting online reviews for Alpha King that seemed to confirm our experience.

Jeff is an amateur bodybuilder, and he was looking to boost his testosterone levels since he had struggled to bulk up in his 40s. He did notice an increase with Alpha King, but when he compared the results to another supplement, Alpha King didn’t come as close.

- Jeff, Maine

Stu is in his 60s, and in his review, he pointed out that he needed a supplement to help with libido and weight management. While he did notice that the formula gave him better sexual drive, he didn’t find Alpha King was enough for losing weight.

- Stu, Atlanta


Does Alpha King Contain Banned Ingredients?

No, Alpha King doesn't contain banned ingredients. It only uses natural ingredients that won't be flagged on a drug test.

When Is the Best Time to Take Alpha King?

The best time to take Alpha King is after breakfast, lunch, and dinner. Spreading it out this way should give your body a more consistent supply that will help keep your T-levels up.

Our Verdict on Alpha King Supreme

Based on our research and the client's test results, we wouldn’t recommend buying Alpha King. Even though we did have some positive results, it’s not the strongest male vitality supplement.

We’ve had far better results with Testogen, and our clients of all ages have managed to get a measured boost in T-levels, exercise performance, and libido as well.

I have had personal experience with it for over a year now, and it has transformed many areas of my health and fitness.

We Recommend This Instead

One thought on “Alpha King Supreme Review
Does It Really Help With Boosting Testosterone?

  1. I used to be in really bad shape. I was overweight, lazy, and had no energy. I tried every product out there that claimed to help me but nothing worked until I came across Alpha King Supreme. It has changed my life for the better. I lost weight, gained muscle, and became healthier than ever before.
