What is this muscle building supplement? Creatine has the characteristics of amino acids and it occurs naturally in the body. However, due to age and other factors, your body does not produce enough so you have to supplement it if you want to build muscle. It is so popular because it enhances on the spot exercise performance, giving you explosive energy to lift heavier and longer.

The science behind it

To reiterate, it mimics the functions of amino acids. It has ingredients such as Tri-Sodium and Potassium, which help the muscles to contract when you are lifting. Sodium also helps to keep you hydrated. Aquamin® Mg & Ag increase your fatigue tolerance so that you can work out longer and harder in the gym.

4.    BCAAS

What is BCAAS? This is an acronym for branched chain amino acids. We have nine amino acids and among these, three are BCAAS. They are Leucine, Valine and Isoleucine. The main benefit of BCAAS is that it increases protein synthesis, which leads to increased muscle growth.

The science behind BCAAS Supplements

Foods such as meats, dairy products and eggs contain BCAAS. But they do not have enough quantities so you must supplement your daily intake of the same especially if you want to build lean muscle. BCAAS also decreases muscle soreness, and helps in recovery.


The ingredients of your BCAAS product depend on the product that you are using. However, most of them contain Leucine, L-Isoleucine and Valine.  

How it works

BCAAS are perfect for use as pre workouts as well as post workouts. When you take it as a preworkout, you give your body the fuel that it needs to increase muscle mass rather than reduce it. When you take it as a post workout supplement, you give your body the resources that it needs to recover and beat after workout soreness.

How to use BCAA

Always read all the instructions of the BCAAS muscle supplements that you buy. Generally, take the preworkout in the recommended dosage at least 15 minutes before working out. That way, it gives your body fuel to burn so that it does not burn its muscle. If you are taking PMD Sports BCAAS, mix one scoop with about 400ml of water in a shaker, shake well and drink 15 minutes before working out.

Pros Cons

1.    Bitter Orange Extract

When reading reviews for the best muscle building supplements, you will most likely find the Bitter Orange Extract in the mix.

What is it?

Bitter Orange Extract comes from the Bitter Orange Tree that grows in Asia. For ages, different parts of this tree have been used as medicine for different ailments, including obesity.

More specifically, the bitter orange extract is used to enhance athletic performance, burn fat and help in amassing muscle mass. Many sports nutrition companies blend bitter orange extract products. However, for the sake of reference, here, we shall consider SYNEBURN, which is one of the top bitter orange extract products.

The science behind it

This product is blended to increase the rate of metabolism. Thus, if you are working out, the body burns fat reserves. High fat metabolism leads to lean muscle formation and fat burning. This extract also has p-synephrine, which improves blood sugar regulation as well as glucose transport to the muscles, enabling you to train harder.


Considering our example of the Syneburn Supplement, it has ingredients such as Magnesium Stearate, Advantra Z Bitter Orange Extract, Silicon Dioxide AND Microcrystalline Cellulose. It is packaged in capsules and one bottle has 180 capsules.

How bitter orange extract works

6.    Beta Alanine

What is it? This non-essential amino acid helps the body to produce carnosine, a compound that helps the muscles to withstand longer, high intensity workouts. Food sources that give beta alanine include meat, fish and poultry. However, they do not give you enough so you have to take Beta Alanine supplements.

The science behind it

Beta Alanine works by helping the body produce carnosine. Now, the work of carnosine is to soak up the acids that your muscles produce when you exercise. Thus, you do not suffer from the effects of lactic acid so you can increase your workout duration.


Beta Alanine is used as an ingredient in many workout supplements to prevent the build up of lactic acid in the muscles. Since this is a naturally derived supplement, it has no side effects at all.

How it works

It works by reducing the amount of lactic acid that your muscles release when you are working out. Thus, you can work out harder and longer. When the lactic acid is mopped up, you can tolerate fatigue longer. Beta-alanine also gives short bursts of energy that are very helpful when engaging in Hiit exercises.

Beta Alanine also enhances glycolysis, which is the process of breaking down glucose to provide fuel for working out.

How to use it

To use Beta Alanine, you have to read the user instructions that come with these muscle building supplements. However, generally, you should take between 2 and 5g of Beta Alanine daily, which is up to three scoops of the Beta Alanine powder.  It is recommended that you take 90G of beta-alanine over 30 days.

7. HMB – One of the best muscle building supplements

What is it? Beta-hydroxy-beta-methylbutyrate is one of the best muscle building supplements in the market today. When the body breaks down the amino acid Leucine, it produces HMB. However, since you can only get very small amounts of this compound from foods, you have to supplement it with HMB supplements.

The science behind it

This supplement is very good for preventing muscle loss related to age or disease like HIV. However, in the bodybuilding and fitness industry, HMB supplements are used to prevent muscle decrease. It does this by enhancing how the body uses oxygen when you are performing any exercise. Research has also established that HMB supplements increase muscle strength so that you can work out for longer durations.


Depending on which brand you buy, most HMB supplements contain 1000mg of HMB. Most of them also come packaged in capsules, with most manufacturers packing them in bottles of up to 90 capsules. Each capsule contains 1000mg of HMB.

Again, depending on the manufacturer, the HMB that you buy will have some ingredients. The most common ones are silicon dioxide, microcrystalline cellulose, rice flour and gelatin. They might differ from one manufacturer to another, but most of these will be there.

How HMB works

When you start taking HMB, it works by helping the muscles retain their mass. Thus, even if the supplement does not do anything too noticeable, at least you will not lose muscle. This supplement increases muscle strength, so you can perform your exercises longer to enjoy more benefits.

How to use HMB

Ingredients are naturally-derived so there are no side effects

8. Casein Protein Powder

What is it? This is a slow digestion protein supplement that fitness freaks and athletes take after working out to help with recovery. It also prevents muscle breakdown

The science behind it

It is very simple actually. As a slow-release protein, casein releases its amino acids so slowly in the stomach, so that makes it very good for muscle repair after working out.
