Best Testosterone Booster

Testosterone is important for different parts of a man’s health, including fat loss, muscle growth, bone strength, mood level, energy level, overall health, and, of course, libido. If a man suffers from low testosterone levels, all of these areas will suffer as well. A man with low testosterone levels may lose muscle mass, increase fat levels, have a low mood, or can even get easily depressed, and consequently, he’ll have low libido.

Unfortunately, our modern lifestyle causes more harm than good when it comes to testosterone levels. The abundance of fast-food products and processed foods, the sedentary lifestyle we’ve got, and just plain simple lack of exercise are just some of the factors that have decreased testosterone levels in men. Add in that testosterone levels already decrease as men age, and it’s no wonder men are looking for something to help. That’s why testosterone boosting supplements (or simply called “testosterone boosters”) are now in high demand.

With all of that in mind, you may now be wondering, what is the best testosterone booster? That’s what we’re here to find out! In this guide, we’ll take a closer look at testosterone boosters. We’ll discuss their benefits, ingredients, and – of course – give you our picks for the best testosterone booster choices.

Let’s get started!

With an increase in testosterone also comes the added benefits of increased energy, better muscle gains, and enhanced performance during physical activities.

Some testosterone boosters will also include additional ingredients that can further benefit other areas of health. For instance, vitamin D is included in many formulas which can promote bone health and help enhance mood. Protein is another popular ingredient in testosterone boosters that can not only help promote testosterone levels, but also benefit weight management and lean muscle growth.

Testosterone Boosters FAQ

What exactly are testosterone boosters?

Testosterone boosters are supplements designed to do exactly as they say, boost testosterone. As the primary sex hormone within men, testosterone plays a vital role in many areas of health. It is responsible for libido, vitality, and stamina as well as promoting muscle mass, strength, bone mass, and promoting the synthesis of protein.

As men age testosterone levels will decline, which can lead to a variety of health issues. The vitamins, minerals, and other ingredients in testosterone boosters work to naturally increase and promote testosterone production. High levels of testosterone then drive muscle strength, size, energy, stamina, and performance.

What are some key ingredients in testosterone boosters?

Ashwagandha is a powerful herb that has long been used in ancient Indian medicine. Even in ancient times, ashwagandha was believed to help improve a man’s libido. Ashwagandha is also linked to improved strength and vitality.

Modern research tends to agree with this belief, as well. For instance, one study suggests that ashwagandha can aid in fat loss, increase physical performance and strength, and significantly boost testosterone levels

Vitamin D is known to help enhance mood and build stronger bones – it works side by side with calcium to help achieve calcium’s purpose of improving one’s bone health. But vitamin D is also shown to work as a natural testosterone boosting supplement.

For instance, according to one study, participants in a weight-loss study were given either 3,332 IU of vitamin D or a placebo to be consumed daily over a one-year period. At the end of the study, men who consumed vitamin D were shown to have higher testosterone levels, while those who only took a placebo did not have any significant increase in your testosterone level.

Protein does not only help build and maintain muscle growth, but it can help with testosterone levels as well. According to the article in the Journal of the International Society of Nutrition, diets that are high in protein may raise testosterone levels.

Muscle, fat loss, and testosterone levels somehow work together. A leaner body tends to have high testosterone than those who have excess fat. On the other hand, muscles can help you burn fat, which explains why muscular people won’t quickly go fat compared to those who aren’t – and remember, testosterone plays an essential role in muscles as well!

Zinc is one of the key minerals our body needs to perform well. Aside from other benefits, zinc is shown to be capable of boosting testosterone levels as well.

For instance, according to a 2010 study, zinc could increase serum testosterone levels. However, it does not necessarily improve or help with sexual dysfunction.

Intense exercise can also temporarily hurt testosterone levels. According to a 2006 study, which was conducted on ten male wrestlers, zinc can preserve the said effect, ultimately boosting their testosterone levels instead.

Ginger is a common household spice, so it is something you’ve probably had in your meal. At the same time, ginger is also used as an herbal medicine for centuries ago.

Ginger is indeed beneficial to our health, but it can also boost testosterone levels. In one study, for example, 75 infertile men were given a ginger supplement. After three months, they got an increase in testosterone levels by around 17%!

However, although ginger is officially known for its health benefits, more research is still needed to see the link between ginger and testosterone level.

How do you take testosterone boosters?

Testosterone boosting supplements come mainly in two ways – through your diet or through synthetic products (dietary supplements).

If you will take dietary supplements, most testosterone boosters may come in pill form (except for protein, wherein protein is usually consumed in powder form). There could be liquid form as well if you’re having a hard time taking pills or capsules.

And of course, you can take these supplements naturally. For example, you can get protein from animal sources such as red meat. On the other hand, you can simply add ginger to your meal.

Do testosterone boosters really work?

Testosterone boosters do work, although it may not be what you’re expecting. As mentioned above, don’t fall for “big promises” marketing.

Because testosterone boosters (at least, on this list) are natural supplements, they should work well just by themselves. Just be sure that when you’re purchasing your dietary supplement, there’s enough of the supplements that you intend to take – not too low, but not too much as it can cause unexpected side effects.

Are testosterone boosters right for you?

Since the testosterone boosting supplements we’ve listed here are natural supplements and are even beneficial to our health, they will correctly work well with the average person. However, if you have a medical condition, ask your doctor first before taking supplements to be sure that you will not face any unexpected side effects.

Are there alternatives to testosterone boosters?

Like many supplements, the main alternative to testosterone supplements is consuming vitamins and minerals that also add the benefits that these would provide for the body. As we mentioned above, some common ingredients in testosterone boosting supplements include zinc, ginger, ashwagandha, protein, and vitamin D. 

If you prefer not to take a supplement marketed as an overall “testosterone” supplement, then your best bet is to consume the above vitamins and minerals.

Are testosterone boosters worth using?

If you’re looking to boost your t-levels, testosterone boosters are worth giving a try. Testosterone booster supplements are secure and safe supplements to test that carry a variety of benefits including better performance, increased energy, bigger muscle gains, and much more. If you start taking testosterone booster supplements and experience any adverse symptoms, contact a medical professional for help.
