What Is a Testosterone Booster?

T- boosters are supplements created with several natural ingredients that are clinically proven to boost the body’s natural testosterone production to fight the symptoms of low testosterone.

They are not to be confused with anabolic steroids, injectable synthetic hormones that are popular among bodybuilders due to their ability to improve muscle mass and athletic performance.

How Does the Testosterone Booster Work?

Each testosterone booster is created with a different blend of ingredients designed to address the effects of low testosterone differently.

woman working out

Most of them are created with vitamins like zinc and D-aspartic acid to increase the body’s free testosterone. Depending on which booster you choose, they will also include specific ingredients designed to lower cortisol levels, fight erectile dysfunction, and provide lasting testosterone support.

What Are the Common Ingredients Used in Testosterone Boosters?

Some of the most common ingredients you will see in testosterone boosters are:

  • Zinc:

Zinc has been proven to boost the total amount of serum testosterone, the amount of testosterone that can be measured in the blood.

Although the T-boosting effects of zinc are less potent in anyone with sufficient levels of this mineral, zinc deficiency is a common problem, especially for anyone 50 years of age or older.

Restoring healthy levels of zinc is an easy way to combat the effects of low testosterone in the body.

  • D-Aspartic Acid: 

D-Aspartic acid is a combination of two amino acids: aspartic acid and L-aspartate. Both of these hormones help to trigger the production of testosterone in the brain and also the testicles.

Not only that, but D-Aspartic acid also boosts the production of the hormone HGH, which, when combined with testosterone in the right ratio, can maximize muscle growth, fat burning, and even sexual performance.

  • Vitamin D/D3

The main function of Vitamin D is to the amount of calcium and phosphate in the bone, both of which are needed to keep bones, muscles, and teeth healthy.

However, research suggests that men who are vitamin D deficient are also more likely to have issues related to low levels of testosterone.

This is because the male reproductive tract has been proven to be a target tissue for vitamin D, meaning that when it enters the body, it will be directed towards this area to aid in producing and maintaining sperm.

  • Bioperine

Bioperine, also known as piperine, doesn’t help boost testosterone production per say, but it does offer a host of other benefits, like improving energy levels and enhancing the metabolism.

Because of this, it’s often found in testosterone boosters that aim to enhance athletic performance and natural fat burners.

  • Fenugreek

Fenugreek is an ancient herb that is chock full of a wide array of vitamins and minerals, including calcium, iron, potassium, and zinc.

Taking any amount of this herb can help you battle the effects of low testosterone and restore a healthy sex drive.

What Are the Benefits of Using a Testosterone Booster?

The ingredients in all T-boosters are a little different. Apart from helping boost testosterone production, some of the popular additives, like ashwagandha, can provide benefits like a decrease in cortisol levels and overall testosterone support.

When it comes to the effects of increasing testosterone, there are a few benefits you can expect, regardless of which booster you choose, including:

  • Increased libido and stamina 
  • Improved muscle mass
  • Stronger bones
  • Improved mood
  • Better mental focus
  • More energy
  • Increased sperm production
  • Increased sex drive

Are There Any Side Effects of Using Testosterone Boosting Supplements?

The most common side effect of taking natural testosterone boosters is an upset stomach, but there are other potentially serious side effects that you should watch out for, including:

  • Excessive hair loss or growth
  • Hormonal acne
  • Heart issues
  • Kidney disease

It’s important to keep in mind that the desired effect of any testosterone booster is to balance hormone levels. Abnormally high testosterone levels can result in things like low sperm count, prostate enlargement, and a higher potential for heart disease.

Before taking a testosterone booster it’s a good idea to test your T-levels with a doctor to ensure that you are a good candidate for supplementation.

If you experience any negative effects, discontinue use and speak to a healthcare professional.

FAQ: 

How can I increase testosterone in my 50s?

At any age, you can help boost testosterone production by doing strength training exercises, improving your diet, reducing stress, and getting more sleep.
If none of this works, you might also consider taking a natural testosterone supplement.

Who should not take a testosterone booster?

Anyone with a history of heart or kidney disease or who is currently on medication should consult their doctor before taking any supplement, including testosterone boosters.
It’s also not recommended for men below the age of thirty to take testosterone boosters since their levels of this hormone don’t begin decreasing before then.

How long does it take for testosterone boosters to kick in?

Most companies that produce testosterone boosters recommend taking the recommended dose every day for at least 2 months before expecting to see results.
However, some users report feeling an increase in energy and mood within 3 days of starting a new testosterone support supplement.

What is the best testosterone booster for men over 70?

There is no single testosterone booster that is best for men over 70.
Since men at this age tend to suffer from deficiencies in vitamins like zinc, potassium, and calcium, there are certain ingredients that men in this age group should look out for.
Any testosterone supplement that includes D-aspartic acid, zinc, magnesium, and vitamin D should help improve T levels while also providing additional boosts of important vitamins and minerals.

Are testosterone booster supplements safe?

Natural testosterone boosters are made with FDA-approved ingredients that are scientifically proven to increase t-levels while producing little to no adverse side effects.
