There are plenty of testosterone boosters on the market. The problem is that many testosterone supplements contain synthetic ingredients, many of which are undisclosed or have side effects that have yet to be thoroughly studied.

To spare you the legwork, we decided to take a good look at the ingredients of the T boosters on the market that claim to be the best, and here’s our take on one of the more popular testosterone boosters on Amazon - Alpha Strength.

About the Brand

Joe and Justin, the two guys behind the Natural Force brand, aim to provide supplements that only contain organic ingredients. They believe that supplements that are fully or partially made of synthetic ingredients contradict the objectives behind good nutrition.

You can find out more about their story and their brand on their official website:

Natural Force Alpha Strength can improve your Testosterone levels naturally. It may enhance your muscle mass and strength as well.

Main Ingredients

This Alpha testosterone formulation has all-organic ingredients. This isn’t really new because there are plenty of other all-natural testosterone boosters out there. However, Natural Force does have a great formulation going in this product.

Why Go All Natural?

But you might ask: What’s the reason behind the hype for all-organic ingredients? And what makes Alpha Strength one of the best testosterone boosters out there?

The reason behind the hype is the prevalence of testosterone supplements that contain synthetic ingredients or prohormones. Such ingredients boost T levels by acting as replacement to natural hormones.

Therein lies the problem. Your natural testosterone production can be hampered when taking these artificial products, which can make your low testosterone problem even worse.

Your testicles may even shrink from the use of legal steroids and prohormones that promise to increase testosterone levels. Once you stop using them, you might end up with any of the following withdrawal symptoms:​

  • Feelings of Depression
  • Irritability
  • Low Libido
  • Low Energy
  • Estrogen Dominance

So if you want to boost your T levels without risk suffering from the above mentioned symptoms, it would be a good idea to opt for all-natural supplements such as Alpha Strength.

It does not even contain any food coloring, artificial sweeteners, or stimulants. The ingredients behind this testosterone booster are divided into two categories based on mechanism:

  • 1. Natural Testosterone Support
  • 2. Natural Anti-Aromatase (Anti-Estrogen)

Natural Testosterone Support

The first group of Alpha Strength’s natural ingredients is intended to enhance the body’s natural testosterone production without shrinking your testicles and causing withdrawal symptoms later on.


Shilajit is a staple of Ayurveda, the world’s oldest traditional medicine system. For decades, it has been used extensively to cure a variety of problems involving male sexual function.

This ingredient is taken from sedimentary rocks, mostly in the Himalayas. It contains rock minerals, rock humus and plant metabolites.

Alpha Strength’s shilajit extract is the standardized PrimaVie extract and serves as the main ingredient. Several studies have proven this ingredient’s ability to promote high testosterone levels in men.​

Tribulus Terrestris

The saponin-rich tribulus terrestris herb has also been used as a natural testosterone booster during ancient times. In addition to its benefits for your reproductive health, this ingredient is also deemed beneficial for other organs and systems such as:

  • Muscle Tissues
  • Kidney
  • Liver
  • Immune System
  • Cardiovascular System

Muira Puama

Muira Puama is the South American continent’s most popular natural testosterone supplement. It is even dubbed as Amazon’s Viagra.

Just like the aforementioned organic ingredients, this has been used widely in the past, too.

Both men and women natives in the Amazon region actually take advantage of this ingredient as a natural aphrodisiac. The natives refer to it as potency wood as they believe that Muira Puma promotes sexual potency.​


The Fenugreek herb is rich in vitamin and nutrients such as:

  • Vitamin B6
  • Copper
  • Manganese
  • Magnesium
  • Iron

It also contains dietary fiber, protein, and phytonutrients namely saponins and choline. Fenugreek has been shown to increase testosterone by blocking its conversion into DHT, thereby keeping more as testosterone in the body. It has also been shown to increase prolactin in some men. Both of these mechanism makes it less ideal for men since DHT is good for sexual function and prolactin is bad for sexual function. This ingredient is the only one we don't like in Alpha Strength.

Natural Anti-Aromatase

In contrast to the first group, the natural anti-aromatase content of Alpha Strength is intended to halt the activities of aromatase enzyme. This substance is responsible for the conversion of testosterone into estrogen.

So why is it important to stop such conversion? Well, what’s the use of boosting your T levels if your testosterone ends up being converted into something else?

An ideal T booster should both enhance and sustain your testosterone levels. One way of sustaining it is by preventing testosterone from being converted into estrogen, also known as the female sex hormone.​

White Button Mushroom

White button mushroom contains phytochemicals that are beneficial for both men and women. This delicious fungus is a great aromatase inhibitor as proven by a study.

It also does the following:​

  • Fights Inflammation
  • Repairs Cells
  • Boosts Energy


Turmeric is the most flavorful natural ingredient of the bunch. In fact, your favorite curry dishes will not be complete without this yellow spice.

Curcumin is the active compound in turmeric, which may help lower your estrogen levels.

Aside from its anti-aromatase properties, turmeric may also be regarded as a testosterone booster in its own regard.​

Black Pepper

Black pepper is beneficial on its own because it:

  • Enhances Metabolism
  • Fights Inflammation
  • Protects the Body From Free Radicals

However, this spice is also valuable when used along with other natural ingredients.

Black pepper aids in transporting nutrients to various parts of the body. As a result, more nutrients are being delivered and absorbed by the right organs.

That is black pepper’s main task as an ingredient in Alpha Strength. It enhances the delivery and absorption of the nutrients from the other ingredients.​

Alpha Strength Effects

By taking Natural Force Alpha Strength, you may experience the following benefits from higher testosterone levels:

  • Better Sex Drive and Sexual Performance
  • Better Memory
  • Healthier Heart
  • Improved Mood

The supplement may also boost the adenosine triphosphate levels in your blood. ATP is the main energy source used by your cells to perform their respective bodily functions.

The Fenugreek content in Alpha Strength may be a disadvantage to some men, though. This is why we advise you not to take this supplement if you already have low DHT and/or high prolactin.

As based on a 2010 study, the Fenugreek herb can further increase prolactin and decrease DHT.​

How to Use

You have to take two capsules 30 minutes before going to sleep, whether it is a training or a non-training day.

During your training or workout days, you have to take two capsules 30 minutes before you engage in physical activity.

During your non-workout days, you have to take the two capsules 30 minutes after you wake up.

It is recommended to use the product for 90 days to see the intended results.

It is also a good idea to combine this supplement along with foods that boost T levels such as:​

  • Oysters
  • Eggs
  • Pomegranates
  • Almonds
  • Grass-Fed Butter

The Verdict

Things We Liked

  • Effective Testosterone Booster
  • All-Organic Ingredients
  • Generally Safe to Use
  • No Stimulants

Things We Didn't Like

  • Reduction of DHT in Some Men
  • Increases Prolactin in Some Men
