Below are some common ingredients of pre-workout supplement.


Our body produces a different kind of amino acids naturally and one of them is L-citrulline. This amino acid improves blood flow to body tissues and enhances the performance during exercise.

With L-citrulline, during exercise, our active muscles will get required oxygen and nutrition.

The L-citrulline amino acid can be found in food or pre-work supplements. Many green vegetables such as spinach, arugula, and food such as beetroot, watermelon, garlic, and seafood are rich in L-citrulline

According to research, L-Citrulline improves performance in kinetic and high-intensity exercise such as cycling.

Another study showed its effectiveness in relieving muscle soreness and improving athletic anaerobic performance.

Branch chained amino acids (BCAA’s)

Branch chained amino acids are the combination of three essential acids (Valine, leucine, and isoleucine). Out of all amino acids in our body, BCAA’s are about 35-40%. They are essential for producing energy during workouts.

Natural Pre-workout supplements with BCAA’s improve the exercise performance, boost muscle growth, reduce fatigue and even help in weight loss.

Many foods are an excellent source of BCAA’s such as:

  • Beans and lentils
  • Meat, fish, and poultry
  • Milk and cheese
  • Eggs
  • Tofu
  • Pumpkin seeds
  • Nuts


Beta-Alanine is a common ingredient in a popular pre-workout supplement. This amino acid benefits overall health enhances performance and especially popular among fitness enthusiasts and athletes.

It is a non-essential amino acid and our body uses it with histidine to produce carnosine. Carnosine improves athletic performance by reducing lactic acid accumulation in active muscles during high-intensity exercise.

Beta-Alanine is recommended if you do high-intensity exercise which lasts between 1 to 4 minutes. Meat, poultry, and fish are a good source for Beta-Alanine.


Creatine is the molecule, found naturally in our body cell. During high-intensity exercise or heavy lifting, it helps muscles by producing energy.

About 95% of creatine is found in body muscles in the phosphocreatine form. The rest 5% is found in liver, kidney, and brain.

During exercise, phosphocreatine helps your body to produce a high-energy molecule which improves your performance.

Natural pre-workout supplements with creatine have many benefits such as:

  • Giving you energy required for the high-intensity workout or heavy lifting.
  • Improves cell signaling which has a positive impact on muscle repair and muscle growth
  • Reduces muscle breakdown which can increase total muscle mass

Studies have shown 5-10% strength gain from weight training program with creatine supplements. It also increases performance and muscle mass.


Caffeine is popular in pre-workout supplements because of its effectiveness in exercise performance. In a different exercise such as sprinting, cycling and weight training you need to produce force fast. Caffeine stimulates the central nervous system and brain which help you to stay alert and give required power.

There are neurotransmitters in the brain which relax it and make you feel tired. Caffeine blocks these neurotransmitters and gives focus and alertness.

Caffeine is generally safe under moderate amount but it can have side effects for some peoples. Trouble in sleeping, anxiety, and restlessness are some of the common side effects. Also, it can be addictive and excess intake can give a headache, migraine, and high blood pressure.

It is recommended to discuss with your doctor before you take any supplements.


Nitrate is found in food such as beetroots, turnips, and spinach. Our body uses nitrate to for nitric oxide which has the number of benefits for overall health.

Nitric oxide relaxes our blood vessels and improves the blood flow circulation. With improved blood circulation our active muscles get more oxygen and nutrients.

Pre-workout supplements with nitrate are recommended if you do endurance exercise such as cycling or running.

Sodium bicarbonate

Sodium bicarbonate is a common household ingredient found in sports supplements. They can reduce the acid build up in the body which helps in reducing fatigue during exercise.

Before taking sodium bicarbonate it is recommended to consult with your health professional.
