What Is L-Arginine?

Best L-Arginine Supplements

L-Arginine is a protein. It is an acidic building block that the body requires to function properly. Some amino acids (like L-Arginine) are semi essential in nature. Sometimes, our bodies just do not produce as much as we need or we need more than our bodies produce, and that is why we require supplements.

L-Arginine is found in dairy products, red meat, fish poultry, and other protein-rich foods. High amounts of arginine are needed in our bodies when we have undergone a surgical procedure, suffered from trauma or burns.

Why You Need L-Arginine?

Arginine is an amino acid, and our bodies produce most of it naturally. Amino acids are bits of organic compounds which add up to form proteins and serve as building blocks for helping parts and organs of the body function properly. Amino acids exist in three forms; essential, non-essential and semi essential (conditional).

While our bodies produce all of the nonessential and most conditional amino acids (arginine) we require, essential amino acids can only come from food and supplements. This is why you need L-Arginine supplements to make up for what your body cannot produce naturally. Also, when you have an injury, stress or illness, you might require L-Arginine supplements to help repair tissues.

What L-Arginine Does For You?

L-arginine is an important supplement if your blood circulation is poor. Perhaps you suffer from cold hands or feet because of it, you might want to consider taking the supplement. It is also a very good supplement for your heart and ensures proper cardiovascular function.

When used with other supplements, arginine has been proven to help with erectile dysfunction according to studies. Other studies have associated L-Arginine with the improvement of kidney function, especially after a transplant. It helps weight loss, blood pressure, and muscular growth and function, amongst several other benefits.

Other benefits include;

Assisting with poor diet. As a supplement, it makes up for the defects of a poor diet by providing some of the blocks that a proper diet would’ve provided. If you’re someone who doesn’t eat red meat, poultry food, dairy products, fish, and some other arginine foods, you might want to consider taking a supplement.

Arginine also helps with physical performance. People engaged in sports and lots of physical activities would benefit from it. It stimulates growth hormone and can help bring about the lean muscles or upper hand you crave.

Things To Look Out For When Choosing An L-Arginine Supplement

There are several L-Arginine supplements on the market. Picking the right one can be a major task. Here are some factors you should consider when choosing a product;

Brand Popularity

When you’re shopping for the right L-Arginine supplement or any other thing for that matter, it is important to go for a brand that has a proven track record. You can ask questions and talk to your doctor or check authentic reviews online.


It is equally important to check the label to see what ingredients were used. It is best to go for a product with as few additives as possible. A supplement is best when it is made with natural ingredients, except for when extracts and other vitamins are needed to help with absorption.

Safety/Side Effects

Also to look out for is the safety of the product. You should check for possible side effects and how people who have used it reacted to it. If you’re not sure about a particular side effect, you should see your doctor. Where there is an ingredient that is harmful to you in any way, it is best to stay away from such products.

How To Best Use L-Arginine?

While there is no standard dose for l-arginine intake, several studies have proposed an average dosage of 2 grams per day. However, depending on your condition and treatment, a smaller or larger dose could be recommended.

L-Arginine supplements usually come in the form of capsules and powder. Where it is powder, using between 1 or 2 scoops on a glass of water would do. Other times, your doctor may advise that you use with other supplements or other liquid substances apart from water.

Concerns and Precautions

While L-arginine has been proven to be very effective, it is not recommended for everyone. Pregnant women and younger people may be advised to desist from taking L-arginine. Also, side effects such as cramps, nausea, diarrhea, allergies, and symptoms of asthma have been noticed with l-arginine supplement usage.

It may also cause low blood pressure and noticeable changes in glucose and blood levels. You are advised to see your doctor if you notice any of such symptoms.
