7 Best Testosterone Boosters for Increased Energy and Muscle Building

If you're a guy looking to boost your testosterone, you've come to the right place.

As a fitness professional and men's health writer, I've spent years researching natural testosterone boosters.

In this comprehensive guide, I'll walk you through how testosterone boosters work, what to look for in an effective supplement, the impacts of low testosterone, and provide my top pick for the best testosterone booster on the market.

How Testosterone Boosters Work

Testosterone is the primary male sex hormone responsible for muscle growth, fat loss, energy levels, sex drive, and more.

Testosterone boosters are natural supplements designed to give your testosterone levels a gentle nudge in the right direction.

These supplements work in a few key ways:

  • Increase Luteinizing Hormone – The pituitary gland in your brain produces LH, which signals your testes to produce more testosterone.
  • Testosterone boosters containing ingredients like zinc and magnesium encourage your pituitary gland to release more LH.
  • Limit Sex Hormone Binding Globulin – SHBG is a protein that binds to testosterone, rendering it inactive.
  • Some herbal ingredients, like nettle leaf, can reduce SHBG, leaving you with more free testosterone.
  • Improve Testicular and Prostate Health – Some plant extracts and amino acids have been shown to enhance testicular and prostate function, allowing your body to produce testosterone more efficiently.

By taking advantage of these mechanisms, the right testosterone booster can give your T levels a measurable uptick in just a few weeks.

What to Look for in a Testosterone Booster

Not all testosterone boosters are created equal. Here are the key features I look for when evaluating a testosterone supplement:

  • Clinically Effective Ingredients – You want tried and true ingredients like D-aspartic acid, zinc, fenugreek, and vitamin D rather than exotic herbs and underdosed formulas.
  • Optimal Dosages – Check that the supplement provides enough of each active ingredient to make a difference. Avoid proprietary blends that don’t disclose exact dosages.
  • Good Manufacturing – Seek out brands that follow FDA guidelines for quality and purity. Made in the USA at a GMP facility is ideal.
  • No Artificial Additives – Steer clear of unhealthy colorings, binders, fillers, and preservatives.
  • Positive Customer Feedback – Reviews from real users can tell you if the product delivers noticeable benefits.

Side Effects from Low Testosterone

If you're experiencing lackluster muscle growth, low energy, reduced sex drive, or other issues, low testosterone may be to blame. Here are some key effects of low T:

  • Decreased Muscle Mass – Testosterone is essential for building lean muscle. Low levels lead to muscle loss and reduced strength.
  • Weight Gain – With less muscle and slower metabolism from low T, unwanted fat gain often follows.
  • Low Energy Levels – Testosterone helps regulate energy production in cells. Low energy and fatigue are common with reduced testosterone.
  • Erectile Dysfunction – Testosterone is a key hormone for libido and erection quality. Low T correlates with reduced sexual performance.
  • Mood Changes – Declining testosterone can negatively impact self-confidence, motivation, and cognitive function.

The good news?

Getting your testosterone levels back to an optimal range can reverse these effects and get you performing at your best again.
