Does Pea Protein Powder Contain Lactose and Amino Acids?

Author: Nicole Adler   Date Posted: 29 November 2016 

Pea protein powder is a plant-based supplement in our range of Australian online supplements. It is commonly used as an alternative for whey protein, or other animal-based protein supplements. If you have been wondering if pea protein powder is suitable for lactose-intolerant athletes, or if you want to know if pea protein provides all the amino acids you need for your fitness goals, please read our information below.

Does Pea Protein Contain Lactose?

The pea protein powders inside our range of Australian online supplements do not contain lactose, because this substance is only present in certain dairy products. Therefore, pea protein powders from our Australian online supplements range are incredibly popular with vegans, vegetarians and lactose-intolerant athletes.

Does Pea Protein Contain a Good Amino Acid Profile?

All plant-based protein powders in our range of Australian online supplements have a good amino acid profile. Pea protein supplements from our range of Australian online supplements are especially high in branched chain amino acids, and generally has a profile that almost matches that of whey protein.

However, there are some differences between the amino acid profile of whey protein and pea protein, because pea protein contains higher levels of arginine, lysine and phenylalanine. Still, the amino acid profile of pea protein is quite balanced, and therefore able to provide athletes with numerous physical and health benefits.

What Is Arginine?

Arginine is an amino acid that is often referred to as L-arginine. The amino acid fulfils numerous functions in the human body; this includes, but is not limited to: wound healing, waste removal, hormone functions, vasodilation and maintaining the function of the immune system.

Studies have also shown that arginine has multiple benefits for your cardiovascular health, because once arginine is consumed, it changes into a substance called nitric oxide. NO or Nitric Oxide is a neurotransmitter, which means this substance can help to relax the blood vessels and improve circulation.

Due to the cardiovascular benefits of arginine, the amino acid could reduce some of the symptoms that are experienced by clogged arteries, chest pains, angina and coronary artery disease. Medical researchers are still considering the effects of arginine on cholesterol or long-term heart health.

What Is Lysine?

Lysine is an amino acid that is commonly found in protein-rich foods such as beans, cheese, yoghurt, milk and meat. Unfortunately, proteins obtained from wheat and corn can be quite low in lysine, which is why vegetarians and vegans often must acquire this amino acid from a pea protein supplement.

The amino acid lysine is an essential amino acid, because the body cannot produce it. Therefore, athletes must obtain this amino acid from their diet or supplements. Getting lysine from dietary sources is important though, because lysine has many different purposes. The functions of lysine are not limited to sports-related benefits either, because this amino acid is also used in the medical world.

Lysine is being studied for the prevention and treatment of herpes-related infections and cold sores. The amino acid has also shown to increase the absorption of calcium in the intestines, and reducing the excretion of calcium by the kidneys. Therefore, there are some indications that lysine could prove useful for patients suffering from osteoporosis.

In addition to all the medical benefits already mentioned, lysine can also increase muscle mass, lower glucose levels and reduce anxiety. Therefore, we can state that lysine does not only have physical benefits, but also psychological benefits.

What Is Phenylalanine?

Phenylalanine is an amino acid that may occur in three different forms: D-phenylalanine, L-phenylalanine and DL-phenylalanine. Out of these three types of phenylalanine, L-phenylalanine is the important one, and the amino acid that is found in supplements and foods. The function of D-phenylalanine is currently unknown, while DL-phenylalanine is an amino acid that does not naturally occur, but is made in a laboratory.

L-phenylalanine can be found in numerous dietary sources; this includes meat, fish, eggs, cheese and milk. Unfortunately, these major sources of phenylalanine are obtained from animals, which could make the acquisition of phenylalanine difficult for vegans and vegetarians. Therefore, they may use a supplement to still get this amino acid in their system.

Amino acid phenylalanine is not only used for fitness benefits, since this amino acid has loads of benefits in the medical world as well, similar to the other amino acids we already described. Phenylalanine is currently used during the treatment of depression, attention deficit-hyperactivity disorder, Parkinson’s disease, chronic pain conditions, osteoarthritis, rheumatoid arthritis, alcohol withdrawal and vitiligo.

The various functions of phenylalanine can be explained by the fact that the body needs phenylalanine to create certain chemical messengers inside the body. However, scientists are not 100% certain on the exact working method of phenylalanine.

What Can I Use Pea Protein Supplements for?

Pea protein supplements can be used for a variety of fitness goals, considering the excellent amino acid profile this supplement has. In general, pea protein powder is commonly used for weight loss and muscle building, but it also has applications for sports performance and endurance.

Can I Get Similar Plant-Based Protein Supplements?

Non-vegan athletes have many options in our range, so vegan athletes should have the same. Therefore, Nutrients Direct has added numerous plant-based protein supplements, which do not contain any animal products.

In addition to pea protein isolate, vegan athletes can also find rice protein powder and soy protein powder. To determine which one is most effective for your fitness goals, try alternating between supplements and measure your results over time. Once you have your results, you will discover the perfect plant-based supplement for your fitness goals.

When you record your results for each plant-based supplement, be sure to include how you are feeling and how easy it is to digest the supplement in question. In some cases, supplement choice is not only determined by result, but also by how the supplement is tolerated by the athlete.
