L-Arginine

(total products: 29)
L-arginine is an amino acids, which is one of the building blocks of protein. It is considered to be a semi-essential amino acid, which means that under certain conditions, such as during growth or injury, the body may not produce enough L-arginine to meet its needs, and it must be obtained from the diet or through supplementation. Great for the cardiovascular system through the synthesis of nitric
oxide. L-arginine plays a variety of roles in the body, including:   Production of Nitric Oxide: L-arginine is a precursor to nitric oxide, a molecule that helps to relax blood vessels and improve blood flow. This is why L-arginine is often used to support cardiovascular health. Protein Synthesis: L-arginine is involved in the synthesis of proteins in the body, which is important for growth and repair of tissues. Immune Function: L-arginine is also involved in immune function, helping to support the activity of white blood cells and other immune cells. Hormone Production: L-arginine is involved in the production of certain hormones, such as insulin and growth hormone. L-arginine is mainly found in protein-rich foods, including meat, poultry, fish, dairy products, and nuts. However, some people may not get enough L-arginine in their diet, and may consider taking L-arginine supplements to support their health. It's important to note that L-arginine supplements may interact with certain medications and medical conditions, so it's always best to speak with a healthcare professional before starting any new supplement regimen.

What advantages does l-arginine


L-arginine is associated with several potential health benefits, including:
 

  • Improved cardiovascular health: L-arginine is a precursor to nitric oxide, which helps to relax blood vessels and improve blood flow. This may help to lower blood pressure and reduce the risk of cardiovascular disease. Recommended for people who want to lower high blood pressure, combine well with the amino acid citrulline. The combination of these supplements will help reduce blood pressure and blood sugar.

  • Improved exercise performance: L-arginine may help to improve exercise performance by increasing blood flow to muscles, reducing fatigue, and improving endurance.

  • Wound healing: L-arginine plays a role in the synthesis of proteins, which are important for tissue repair and wound healing.

  • Immune system support: L-arginine is involved in immune function, helping to support the activity of white blood cells and other immune cells.

  • Erectile dysfunction: L-arginine may help to improve erectile dysfunction by increasing blood flow to the penis.

  • Reduced inflammation: L-arginine has anti-inflammatory properties and may help to reduce inflammation in the body.

 

It's important to note that while L-arginine is generally safe for most people when taken in recommended doses, it may interact with certain medications and medical conditions. Therefore, it's always recommended to speak with a healthcare professional before starting any new supplement regimen.

 

L-arginine contraindications


While L-arginine is generally safe for most people when taken in recommended doses, there are some contraindications to be aware of. These include:
 

  • Herpes simplex virus: L-arginine may increase the replication of the herpes simplex virus, which can cause outbreaks of cold sores or genital herpes. Individuals with a history of herpes should use L-arginine supplements with caution.

  • Low blood pressure: L-arginine may lower blood pressure, which can be problematic for individuals with already low blood pressure or those taking medications to lower blood pressure.

  • Recent heart attack: L-arginine may increase the risk of death in individuals who have recently had a heart attack.

  • Kidney disease: L-arginine is cleared from the body by the kidneys, so individuals with kidney disease may need to avoid L-arginine supplements or use them with caution.

  • Pregnancy and breastfeeding: The safety of L-arginine supplements during pregnancy and breastfeeding is not well established, so it's best to avoid them or use them with caution.

  • Bleeding disorders: L-arginine may increase the risk of bleeding in individuals with bleeding disorders or those taking blood-thinning medications.


 

L-arginine supplementation


L-arginine supplements are available in several forms, including capsules, tablets, and powders. The recommended dose of L-arginine can vary depending on the reason for use, age, and overall health status.

The typical recommended dose of L-arginine for general health and cardiovascular support is between 2-6 grams per day, taken in divided doses throughout the day. For athletic performance, the recommended dose is usually between 6-8 grams per day, taken 30 minutes before exercise.

It's important to follow the manufacturer's instructions when taking L-arginine supplements, as the recommended dose may vary depending on the product.
