The 5 Best Supplements to Gain Muscles

Estimated read time 6 min read

Physical training and nutrition are the main factors in building muscles. Here are the 5 best supplements to gain muscles in 2024 It is healthier to gain muscle mass rather than fat in adipose tissues. For some individuals, workouts and nutrition are not enough. They have to move to other sources of gaining muscle weight. So supplements are the best choice because supplements help build the muscles fast. These are also called, “Ergogenic Aids”.

Runners do not need to intake proteins because they are not doing it to gain muscles. But weight lifters have to supply enough proteins to their body to build muscles. Beginner-level athletes and individuals do not need a supplement for building muscles, as they gain muscle mass through resistance-training exercises. Individuals who are at the peak of their workout should take supplements for muscle mass building.

Proteins for Muscles

According to the national center of biotechnology information, muscles need proteins for metabolism. During the resting state, catabolism is less, but when you start exercising, catabolism of proteins starts. The only way to keep muscle hypertrophy is to supply proteins because muscles need proteins for repairing tissues that got damaged during exercise. If your body has not had enough amino acids, protein catabolism will be more than anabolism, which can’t help build muscles. So protein supplements are essential for you.

List of Best Supplements to Gain Muscles

#2. Arginine

#3. Branched-Chain Amino Acids (BCAAs)

Brief: Best Supplements to Gain Muscles 2024

The foremost parts of weight gain are nutrition and physical techniques. The best supplements to gain muscles are:


Creatine is present in our muscles as creatine phosphate, an energy reservoir. It is the source of energy within our muscles. Whenever you blink your eyes, move your neck, and chew your food, there’s creatine phosphate. When muscles do contractions and relaxations, they harness ATP.

During contraction, one molecule of phosphate is cut off from adenosine triphosphate (ATP), leaving a molecule of adenosine diphosphate (ADP). During strenuous exercise, our body becomes short of an instant supply of ATP. Then creatinine phosphate does its job by providing a phosphate group. This increases during workout times and gives you strength. Long workouts lead to muscle gains.

Creatine is a popular supplement for gaining weight since 1990. The most economical and popular variety of creatine comes as creatine monohydrate.

Benefits of Creatine

  • Increase muscle mass
  • Improve blood circulation during workouts
  • Decrease inflammation during exercise
  • Give muscles the strength
  • Increase performance while tough training

Recommended dose: According to NCBI, 5 grams of creatine supplement is safe. Experts advise intaking 2.5 grams pre-training and 2.5 grams post-training. But according to FDA, 2 grams per day is enough.

Athletes follow another protocol of taking creatine supplements for five days, 25 grams per day. But it is not necessary. The same results are visible with the 5 grams of creatine. 


Arginine is an essential amino acid that increases protein synthesis in the body. It is effective before and after workouts.

Benefits of Arginine

  • Increases blood flow
  • Act as a substrate for the production of creatine
  • Increase muscle mass
  • Supply nutrients to skeletal muscles
  • Enhances secretion of human growth hormone

Recommended dose: It is a chief protein source, about 9 grams per day is safe to use.

Branched-Chain Amino Acids (BCAAs)

BCAA amino acids include leucine, isoleucine, and valine. Check Striction D review also. These amino acids are essential amino acids, that regulate protein synthesis and protein metabolism. Leucine increases protein production for muscles and regenerates tissues.

Benefits of BCAA Amino Acids

  • Elevates synthesis of muscle proteins
  • Decrease soreness of muscles during training
  • Repair muscle damage
  • Improve endurance

Recommended dose: The effective dose of BCAA includes two parts of leucine, one part of valine, and the other part of isoleucine. 3-6 grams of BCAA is effective before and after exercise.


Beta-Alanine is a non-essential amino acid to make protein in the body. It increases levels of carnosine, present in muscles. Carnosine increases muscle mass by decreasing the accumulation of lactic acid in muscles. Beta-alanine supplements increase the levels of carnosine by about 60% in a month. 

Beta-Alanine increases the stamina of workouts. Carnosine does this by acting as a buffer during hydrogen ions accumulation in the muscles. The hydrogen ions decrease pH, which leads to the lactic acid formation in muscles which causes fatigue.

Benefits of Beta-Alanine

  • Improves power
  • Increase muscle mass
  • Improves endurance
  • Delay fatigues 

Recommended dose: 4-6 grams of beta-alanine per day is effective. Higher doses of beta-alanine can cause skin tingling sensations throughout the body. So take the slightest amount of beta-alanine throughout the day.


Caffeine is not a supplement to gain muscle mass. It is a stimulant of the central nervous system and causes alertness in you. You feel less tired after drinking caffeine which can make you do extra reps. the effort during reps increases your muscle strength. So we can conclude, it’s an indirect connection between caffeine and muscle gain. 

Benefits of Caffeine

  • Increases motivation by blocking adenosine activity
  • Reduces fatigue
  • Increases endurance

Recommended dose: Daily 0.4-1 gram of caffeine increases tolerance in trainers per FDA recommendations.

Which supplement to choose to Gain Muscles?

Choosing the best supplement can be a bit tricky due to the wide range of varieties. There are more claims of marketing the products rather than the actual health benefits and scientific evidence. The legal supplements help make muscle growth and performance. While picking the best supplement for you, do check the label. The one indicating heavy metals and vitamins in the supplement is not of your choice.

According to the National Institute of Health, stimulants, and synthetic steroids are not safe for athletes as they cause worse after-effects. So, creatine monohydrate is the best to opt for as supplement to build muscle mass.

Bottom Line

Muscle building is a slow process in trainers which requires consistent training, diet, and a healthy lifestyle. Resistance training exercises help a lot in building muscles. But the other choice for gaining lean muscles is supplements. Safe amounts of supplements not only increase muscle mass but gives you endurance and motivation for workouts. It all leads to increased muscle mass.
