What are GNC Testosterone Boosters?

The upcoming sections of this article will help to evaluate the quality of the testosterone boosters offered by GNC.

GNC Testosterone Booster Ingredients

Before evaluating other factors, we must check out the ingredients that are used by the manufacturer. After all, it’s the ingredients that determine the effectiveness of a supplement, which applies to testosterone boosters as well.

Here is the list of ingredients that are chosen by GNC to manufacture testosterone boosters.

1. Betaine (trimethylglycine)

Bethaine is known for its ability to enhance performance. However, the result obtained after the consumption of this compound varies, which makes it unreliable.

Using this compound twice a day can help in enhancing the power output of a person. And, the minor increment in workout volume and endurance may also be experienced (this outcome is a bit more reliable than the previous one, but it’s not a 100% confirmed outcome).

The consumption of 1.25 grams this ingredient is sometimes included in pre-workout supplements
[1]. Here is the link to the detailed study of this compound if you are eager to know more about this ingredient.

2. Trans-Reservatrol

The second important ingredient that is found in this testosterone booster is Trans-Reservatrol. During the tests of this ingredient, the consumption of this ingredient showed an improved inflammatory and atherogenic status. This status was in subjects at the risks for cardiovascular disease.

This status was also observed in patients that were diagnosed with coronary heart diseases. However, the bioavailability of this ingredient is very low, as it is rapidly metabolized and eliminated. The clinical trials of resveratrol in healthy people are limited.

3. Astaxanthin

This ingredient is known for its ability to aid in eye health and inflammation. The study for examining this ingredient found limited human evidence. However, it appeared to be a better carotenoid in comparison to lutein and zeaxanthin, which are more researched.

4. Saw Palmetto

Saw Palmetto is a very popular ingredient that is found in many male enhancement supplements.[2] It is a fatty acid that was well-known for boosting the level of testosterone in the body; however, the test proved that the claim was false.

With that said, this ingredient is not useless at all. This ingredient is effective in suppressing prostate growth, though. This ingredient can be helpful for those men who are taking steroids or Prohormones.

5. Vitamin B6

Vitamin B6 is an important nutrient that aids testosterone levels by stimulating androgen (androgen is a steroid hormone that plays a role of a precursor for testosterone) receptors in the body. The stimulation of androgen leads your testes to produce testosterone.

6. Vitamin B12

Another important nutrient that is found in this supplement is vitamin B12. The study has shown that the people who are anemic are not able to produce enough testosterone because they are not able to absorb vitamin B12.[3]

7. Magnesium



Magnesium is an important chemical element that is often found in many top male enhancement supplements. Magnesium has already proven its effectiveness. The study shows that the intake of enough magnesium boosts the production of testosterone in the body.

8. Zinc

Zinc is another well-known chemical element that is very popular. The intake of enough zinc can significantly boost healthy testosterone production.

9. Riboflavin

Riboflavin plays a crucial role in body growth and red blood cell production. Furthermore, this ingredient also assists in the release of energy from proteins.

10. Thiamine (Vitamin B1)

Thiamine is an important nutrient that helps the body in transforming carbohydrates into energy. The most important function of carbohydrates is to provide energy to the mind, body, and nervous system.

11. Vitamin D

One of the major sources of vitamin D is sunlight. But, many people in the developed nations are deprived of getting enough vitamin D because they are busy in their indoor jobs. Vitamin D is a nutrient that is transformed into a hormone in the body, which is important for muscular growth.

You must make sure that it is vitamin D3 when you’re looking for testosterone boosters. Vitamin D3 is significantly more powerful and effective in comparison to vitamin D2. A person can get enough vitamin D by exposing themselves to sunlight, but they must be careful as ultraviolet rays from sunlight can do a lot of damage.

12. Tribulus Terrestris

Tribulus is found in GNC testosterone boosters as well as in many other supplements. This plant was regarded as a magical plant for a very long period of time, as it was believed that athletes during the cold war used this plant for keeping themselves going.

However, there are no scientific studies to prove that the claims about this plant are true. It’s better to avoid this plant if you’re aiming for muscle gains.

13. Indole-3-carbinol

Estrogen is a female sex hormone. A higher level of estrogen in men can often lead to a lower level of testosterone in the body. Indole-3-carbinol is a negative regulator of estrogen.

14. Niacinamide (Vit B3)

Niacinamide is a very important nutrient. A boost in the level of niacinamide can help in improving cholesterol levels in the body and reduces the risks of cardiovascular diseases.

Furthermore, niacinamide may also be effective in countering the symptoms of Alzheimer’s.
With all the listed benefits of this ingredient, there is no sign of this nutrient enhancing the level of testosterone in the body.

15. Dehydroepiandrosterone (DHEA)

DHEA is a hormone that is naturally produced by the adrenal glands. Our body utilizes DHEA for the production of androgens and estrogens (male and female sex hormones).

The level of DHEA is at its peak at the age of 25, but it goes down quite quickly after crossing that age. When a person reaches the age of 70-80, the level of DHEA is reduced to 10-20% of what is found in young adults.

With that said, there is no enough evidence to prove that DHEA is effective in increasing muscle mass.

16. Fenugreek



Fenugreek is an ingredient that has proven its worth. It’s found in many top male enhancement supplements.

17. Diindolylmethane (DIM)

It’s a compound that is derived from indole-3 carbinol digestion. This compound can be found in cruciferous vegetables, such as cabbage, kale, broccoli, and Brussels. This ingredient can obstruct the process of conversion of testosterone to estrogen.

18. L-Citrulline

L-Citrulline is popularly used as a supplement for enhancing sports performance and cardiovascular health. The consumption of this supplement can reduce fatigue and improve endurance for both anaerobic prolonged workouts and aerobic exercise.

The growth hormone is boosted during exercise, but not while resting.

19. Copper

Copper is found in GNC testosterone boosters, and this comes out as a surprise. According to the study, the high level of copper in the body is associated with low testosterone. This ingredient should have been avoided by the manufacturer.

20. Panex (Korean) Ginseng

The final ingredient on the list is Panex (Korean) Ginseng. This ingredient is one of the most researched ingredients. There are plenty of pieces of evidence that prove that the consumption of this ingredient can result in better cognition, immunity, and mood.

There are also studies of this ingredient, which shows that it is useful for men increased production of testosterone in infertile men and improved erection.
