Types of Supplements for Muscle Growth

Four main types of dietary supplements can help with muscle growth. Each type has its benefits and can help you achieve your goals differently:

 

• Testosterone boosters
• Pre-workout supplements
• HGH supplements
• Mass gainers
• Testosterone Boosters

While your body produces some testosterone naturally, you can also take supplements to increase levels. These types of muscle-building supplements are formulated to help your body produce more testosterone. This can lead to increased muscle mass, strength, and stamina.

Pre-Workout Supplements

Pre-workout supplements help you get the most out of your workouts. They can increase energy levels, improve stamina, and enhance focus and mental clarity. This can help you work out harder and for more extended periods, leading to increased muscle growth.

HGH Supplements

HGH supplements can help increase your body's levels of human growth hormone (HGH), leading to increased muscle mass and strength. HGH supplements can also improve recovery time and reduce inflammation.

Mass Gainers

Mass gainers are typically a type of whey protein powder that contains a high number of calories and carbs. If you find it challenging to eat enough calories or get enough protein from your normal diet, a mass gainer can help you hit your goals.

What To Look For in the Best Supplements for Muscle Growth

When comparing different supplements, we evaluated them on the following criteria:

Clean and Natural Ingredients

Natural ingredients have less risk of side effects and are generally considered safe. This means no artificial colors, flavors, sweeteners, or fillers.

Non-GMO

Non-GMO supplements are not made with genetically modified ingredients. These supplements are generally considered to be safer and more natural. They're also less likely to contain harmful chemicals or pesticides.

Solid Refund Policies

A good refund policy shows that a company stands behind its products and is confident in their quality. This gives you peace of mind that you can get your money back if you're unhappy with the results.

Bulk Discounts

Bulk discounts are an excellent way to save money on supplements. They're also a good indicator that a company is confident in its product and is willing to sell it at a lower price per serving.

Can You Stack Muscle Builders?

Muscle builders can be stacked or combined for even better results. Stacking different supplements can help you customize supplementation to your specific goals.

 

However, do your research first, and always take supplements as directed to avoid any adverse effects.

Does Protein Build Muscle With Supplements for Muscle Growth?

Your muscles are made up of protein and need protein to repair and grow after workouts. Consuming enough protein is essential for building muscle mass.

 

There are many different types of protein supplements, but the best sources for muscle growth are whey protein isolate and casein protein. These protein powders are easily digested and provide your muscles with the amino acids they need to repair and grow.

What Supplements Are Best for Muscle Growth and Bodybuilding?

Some of the best muscle-building supplements for bodybuilders include:

 

• Creatine
• Carnitine
• Glutamine
• Branched-chain amino acids
• Beta-alanine
• Beta-ecdysterone
• Nitric oxide boosters
• Fish oil
• Protein supplements

Creatine

Creatine monohydrate is one of the most popular and well-researched bodybuilding supplements. It's an amino acid that your body uses to create energy. Creatine ethyl ester can increase your muscles' energy production, increasing strength and power output [7].

Carnitine

Carnitine is an amino acid that helps your body burn fat for energy. It's often used as a weight loss supplement and can also help you as a lean muscle builder.

Glutamine

Glutamine is an amino acid that's naturally found in your muscles. It's vital for muscle growth and recovery, and supplementation can help increase muscle mass and strength. Glutamine also has immune-boosting properties, which can help you stay healthy while training hard [9].

Branched-Chain Amino Acids (BCAAs)

Your body can't produce branched-chain amino acids, so you need to get them from your diet or supplements. Branched-chain amino acids are essential for muscle growth and recovery and are often part of post-workout supplements [10].

Beta-Alanine

Beta-alanine is a non-essential amino acid that's naturally found in your muscles. Beta-alanine helps increase muscle carnosine levels, improving exercise performance and delaying muscle fatigue [11].

 

>>See the latest discounts for D-Bal Max

Beta-Ecdysterone

Beta-ecdysterone is a plant-derived compound that's been shown to increase muscle mass and strength. It works by increasing protein synthesis and improving nitrogen retention [12].

Nitric Oxide Boosters

Nitric oxide (NO) is a natural gas produced by your body. It helps to regulate blood flow and oxygen delivery to your muscles. NO supplementation can improve blood flow, increasing muscle pumps and fullness [13].

Fish Oil

Fish oil is a type of fat high in omega-3 fatty acids. These fatty acids are essential for heart health, brain function, and inflammation [14]. Therefore, fish oil supplementation can improve exercise performance and help to repair muscles after exercise.

Protein Supplements

Protein supplementation can help you meet your protein needs, which is vital for muscle growth. Proteins contain all the essential amino acids your body needs and other muscle-building nutrients such as calcium and bioactive peptides [15].

Potential Adverse Effects of Supplements for Muscle Growth

While supplements can be beneficial for muscle growth, some can cause adverse effects, including:

 

• Gastrointestinal issues
• High blood pressure
• Kidney damage
• Liver damage
• Cardiovascular issues

Tips Alongside Using Supplements for Muscle Growth

In addition to muscle-building supplements, there are other things you can do to increase muscle growth. These tips can help you get the most out of your training and nutrition program:

Regular Weight Training and Exercise

To build muscle, you need to exercise regularly. Weight and resistance training are the best types of exercise for increasing lean body mass.

Follow a Strict Diet

To build muscle, you need to eat a diet high in protein. This diet will help your body recover from your workouts and promote muscle growth.

Reduce Stress

Stress can cause your body to release cortisol, leading to muscle breakdown.

Get a Good Night's Sleep

Sleep is essential for muscle growth. During sleep, your body releases hormones that promote muscle growth and repair.
