Buying Guide For L-arginine supplements

Who isn’t a good candidate for L-arginine supplements?

By relaxing blood arteries, L-arginine improves circulation. Although a shortage in L-arginine is uncommon, taking a supplement of the amino acid can aid with certain diseases. Before taking L-arginine supplements, anyone on blood pressure medicine, anticoagulants, heart medication, diabetic treatment, erectile dysfunction pills, pregnant women, or asthmatics should visit their doctor first.

What are the negative consequences of taking L-arginine supplements?

While clinical trials demonstrate that consumers can safely take L-arginine for up to three months, there are a few mild adverse effects to be cautious of. Some users have complained of diarrhea, bloating, abdominal pain, and gout. Patients with asthma should be informed that L-arginine may make it more difficult to breathe. Long-term L-arginine use has not been studied for side effects.

What does it taste like to use L-arginine supplements?

Because of its alkaline nature, L-arginine has a bitter taste. To hide the flavor of the powdered version of L-arginine, you could mix it with other drinks. Flavored L-arginine supplements are available.

What should you look for in a good L-arginine supplement?

Capsules vs. powder

You’ll get the same amount of L-arginine whether you take it in powder or capsule form. The powder has a few advantages that are worth mentioning. It is slightly less expensive and only takes one dose every day. Other liquids and additives can be mixed with the powder form. The powder is also more quickly absorbed by the body, resulting in faster results. For many people, pills are still a feasible alternative because of their portability, absence of unpleasant taste, and lack of mess.


L-arginine comes in three distinct forms. The amino acid L-arginine in its free form is the most similar to the amino acid present naturally in meals.

Because it mixes with hydrogen chloride, L-arginine HCL is easier to digest and does not taste bitter.

L-arginine AAKG is a salt that combines the amino acid with alpha-ketoglutaric acid, a naturally occurring amino acid that is of great interest to bodybuilders who feel it aids overall athletic performance.

No preservatives are used

Look for L-arginine supplements that don’t contain any artificial preservatives or sugar. For dietary support, some L-arginine pills include extra vitamins and folate.

How much should you budget for an L-arginine supplement?

The cost of a month’s supply of unflavored L-arginine pills is from $6 to $10, although they are not USDA-approved. Higher-quality pills and powders cost $10 to $20, while premium L-arginine supplements cost $20 or more and contain additional nutritional support and flavor options.

Final Verdict

After reading this article, you should have a good sense of how L-Arginine is used in supplements and why it is important to the body. L-Arginine can be helpful in treating many diseases and conditions, but it’s not intended as a treatment for any medical condition. If you are considering taking L-Arginine supplements, please consult your doctor to make sure it is appropriate for your health needs.
