Alpha King vs Nugenix (Which One Should You Use?)

I’ve done a lot of research into testosterone boosters and even tried a few myself. See the comparison of Alpha King vs Nugenix.

To be honest, both Alpha King and Nugenix are pretty mediocre, and I personally don’t recommend them. Nugenix, especially, is just all marketing with no real substance behind it.

Personally, I have been taking TestoPrime and really loving it.

Alpha King vs Nugenix Details

Our Top-Rated Testosterone Booster

TestoPrime is currently our No.1 Ranked Testosterone Booster. It has the most effective ingredients formula on the market according to our extensive research and testing.

Alternatively, if you are over 55 and looking for more of an anti-aging complex (energy & libido) – then I would recommend Prime Male (See current pricing here).

Use Prime Male if you are over 55 and looking for more energy in your day to day life.

If you are stubborn and set on taking either Alpha King or Nugenix (I’m not sure why you would be when there are better alternatives, but each to their own). You can read my full comparison below:

Comparison at a Glance

  • If you’d like a testosterone booster that has additional vitamins and better price options, then Nugenix is the one for you,

Ingredients Comparison

Every ingredient has its own set of benefits. The best way to compare two supplements of similar functions is by studying the various ingredients of each supplement.

Since both of these products are testosterone boosters, some ingredients will inevitably be common in both Nugenix and Alpha king. However, little differences in ingredients will help us measure the benefits and make the right decision.

Common Ingredients of Alpha king and Nugenix

Fenugreek – Extracts from fenugreek block hormones and enzymes that kill testosterone. It contains compounds called furostanolic saponins, which are great for increasing testosterone production in the body.

Studies have concluded that fenugreek also helps in weight loss as it decreases your appetite by making you feel less hungry.

Other benefits of fenugreek herbs include improved cholesterol levels and blood sugar levels.

Tribulus – This ingredient is extensively helpful in enhancing libido and athletic performance. However, it does not increase testosterone. It increases the sex drive of consumers, which gives them the confidence that the booster is working.

Tribulus is also helpful in treating high blood pressure, kidney stones, sexual dysfunction, and high cholesterol.

Distinct ingredients in Alpha King

Black Maca Root Extract – The roots of black maca have been prominently used to treat sexual dysfunction in men. The quality of sperm is as important as the quantity of sperm.

Studies have shown that consumption of black maca has resulted in an improvement in concentration and sperm motility and a major increase in seminal volume. However, the hormone levels of those men remained the same.

Diindolylmethane – Found in vegetables such as kale and broccoli, this natural substance brings changes in metabolism and estrogen levels, thereby promoting weight loss and detoxification.

Limited research has been done on diindolylmethane. The substance also helps in preventing certain hormone-dependent cancers.

Distinct ingredients in Nugenix Free Testosterone Booster

Zinc – Found in all parts of the human body, zinc is highly beneficial for increasing testosterone levels. Zinc increases testosterone by influencing the function of aromatase enzyme, which is responsible for converting testosterone into estrogen.

Zinc also facilitates improvement in motility and sperm volume, thereby increasing the man’s libido, potency, and fertility. Deficiency of zinc in the body results in low sperm count and negligible semen volume.

Pyridoxine Hydrochloride (Vitamin B-6) – Our body cannot produce Vitamin B-6 naturally, and it can only be obtained through external sources such as food and supplements.

Pyridoxine has several benefits, such as liver detoxification, healthier skin, better cognitive functions, and prevents hair loss.

Vitamin B-6 has also proven to be effective in mood regulation and reducing the signs of depression as the vitamin is significant in creating mood-regulating neurotransmitters such as serotonin and dopamine.

Methyl cobalamin (Vitamin B-12) – Vitamin B12 is essential for your brain and nervous system as it improves concentration and memory. It facilitates the regeneration of red blood cells, the cell responsible for carrying oxygen in your body.

Other benefits of Vitamin B-12 include improved digestion, better skin health, better mood, and reduced stress.

L-Citrulline Malate – This ingredient is significantly impactful in increasing workout duration, reducing muscle soreness, improving muscle recovery, and cleaning endotoxins from the body. Once you start consuming citrulline malate, you’ll notice a difference in your performance in 15 days or less.

Ingredients Verdict 

Nugenix did not mention the quantity of fenugreek and Tribulus used in its testosterone booster. On the other hand, Alpha king uses 400g of fenugreek and 150g of Tribulus.

The quantity of fenugreek extract used in Alpha King is way less than other testosterone boosters, generally using 1000-2000g of fenugreek extract. Still, Alpha king gets a plus point for having excellent transparency.

Nugenix Reviews
Nugenix Testosterone Boosters

Nugenix offers testosterone boosters produced with natural ingredients. Explore Nugenix's customer reviews and products on Amazon.

Knowing the dosage of each ingredient allows you to add other t-boosters to your stack accordingly. If you plan to do so, Alpha King should be the ideal choice for you.

We’d recommend not choosing Nugenix if you are already taking multivitamins as most ingredients of Nugenix free testosterone booster are found in your average multivitamin supplement.

The problem with Nugenix hiding the dosage of the listed ingredients is that it would make it difficult for you to determine the benefits or possible side effects of each ingredient. In addition, there may also be unlisted ingredients that may not be good for your health.

Alpha king is the better choice based on ingredients. Not only does it break down all of their listed ingredients but also indicates the quantity of every ingredient in each dosage.

In addition, the black maca root extract in Alpha king is excellent for boosting men’s sexual and physical performance. Read our review of Alpha King here.

Safety & Potential Side Effects

Both testosterone boosters are tried and tested products that have gone through several tests before entering the market, so you shouldn’t worry much about your safety while consuming these supplements.

However, there may be some side effects or reactions from the ingredients in these testosterone boosters.

Alpha King

The black Maca root extract used in the Alpha King testosterone booster clears the toxins from your body. In the process of doing so, you may experience headaches in the initial days of consuming it.

There are some cases where people have faced Gastrointestinal issues when they started taking Alpha king. However, these problems often arise when you take new supplements as the body takes time to get used to them.


Like Alpha king, Nugenix is comprised entirely of natural ingredients, and such natural supplements do not usually have major side effects. However, your body may take some time to get used to it, and initial bloating, nausea, and stomach upset are common.

Remember that excessive consumption of either of these supplements can have severe side effects. Another rule is to avoid taking these testosterone boosters on an empty stomach.

Customer Reviews


With 4 out of 5 stars on Amazon, the Nugenix free testosterone booster has fared really well among customers. Most reviews are positive, stating that it has proven to be useful after consuming it for a few weeks.

However, some consumers suffered from high blood pressure after taking it. A few consumers also complained about the lack of transparency as the number of listed ingredients is not disclosed.

Alpha King

Alpha King has several mixed reviews, with Seesaw leaning a little more on the negative side. Some older consumers enjoyed this supplement as it boosted their energy levels and performance.

Others found zero to negligible effect in their performance and were highly disappointed with Force Factor’s Alpha King.

Manufacturing & Brand

Nutraclick International LLC manufactures Force Factor Alpha King. The manufacturer is headquartered in Boston and has seen immense growth in the health and wellness industry, with several award-winning brands under its name.

Adaptive Health LLC manufactures Nugenix. The company is based in Utah, USA, and has been operating for more than eight years.

Alpha King wins this round as it is manufactured under strict FDA guidelines, and safety shouldn’t be an issue with Alpha King as it has gone through rigorous testing. On the other hand, Nugenix is not FDA-approved. 

Price and Value for Money

If price is a deciding factor for you, then you should know that these testosterone boosters have the same retail price. They are high-quality products with some differences in their ingredients.

However, it is worth noting that Nugenix Free Testosterone Boosters get several discounts and offers, which may reduce their cost or offer you a better combo deal. This gives Nugenix an upper edge, making it cheaper and more value for money.

Final Thoughts

Throughout the comparison, Alpha King has proved itself to be the better option. However, regarding customer reviews, Nugenix had a slight edge over Alpha King. 

Alpha King comprises high-quality botanical ingredients, while the ingredient list of Nugenix looks quite similar to the ingredient list of a multivitamin supplement. 

Nugenix hides the number of its listed ingredients, and this lack of transparency is definitely frowned upon by its consumer. On the other hand, Alpha King clearly indicates the quantity of every ingredient in each dosage. 

Although Alpha King has left no stone unturned in proving why it is better than Nugenix, it can still make some enhancement by increasing the quantity of fenugreek extract.
