About the Brand
VitBoost is a health supplement company in the USA. It says its products are made in facilities that follow strict quality and safety rules called GMP standards. The company also lists all the ingredients on its labels so customers know what’s inside.
The brand says its products are free from gluten, soy, and shellfish, which is helpful for people with allergies. However, it doesn’t mention whether it allows independent labs to test its products.
Its 30-day money-back guarantee is good but might not give enough time to see if the product works well. Also, most of its products are only sold online, which could make it harder for some people to buy them.
How Does VitBoost L-Arginine Work?
VitBoost L-Arginine is designed to raise nitric oxide levels in the body so blood flow can improve. Nitric oxide works by relaxing blood vessels, thereby allowing oxygen and nutrients to reach muscles and tissues more easily.
This process is important for energy, endurance, and overall circulation. That’s why the product claims it can support physical performance and heart health by improving oxygen delivery throughout the body.
A study published in the Journal of Applied Physiology Nutrition and Metabolism highlights that L-Arginine supplementation can enhance blood flow and improve exercise performance.
VitBoost L-Arginine Ingredients: Are They Safe & Effective?
Here are the key ingredients in VitBoost L-Arginine, their sources, and benefits:
L-Arginine HCL (500 mg)
L-arginine HCL is an amino acid that helps the body produce nitric oxide. Nitric oxide supports better blood flow and circulation. As documented in our WOWMD L-Arginine Plus Review (another supplement containing this ingredient), this can be beneficial for physical performance and maintaining cardiovascular health.
Research, such as a study in the Journal of Nutrients, highlights how L-Arginine may improve exercise performance and oxygen delivery in the body.
L-Arginine Alpha-Ketoglutarate (500 mg)
This compound combines L-Arginine with Alpha-Ketoglutarate to enhance nitric oxide production further. It’s often used in sports supplements to support endurance and muscle recovery. Studies published in the International Journal of Sport Nutrition and Exercise Metabolism suggest its potential to improve blood flow and reduce muscle fatigue during exercise.
Citrulline Malate 2:1 (500 mg)
Citrulline Malate is known for boosting nitric oxide levels and improving workout endurance. It also helps reduce muscle soreness. Our article titled “Citrulline: Know Everything About This Ingredient” mentions how it’s good for bodybuilding and athletic performance. Research in the European Journal of Applied Physiology demonstrates its role in enhancing exercise performance and reducing post-exercise fatigue.
Cayenne Pepper (40,000 HU)
Cayenne pepper contains capsaicin, which may improve metabolism and circulation. It’s included to support blood flow and potentially enhance the delivery of nutrients to muscles. Studies, such as one in the Journal of Bioscience Reports, discuss capsaicin’s effects on metabolic rate and circulation.
Dr. Jia Zheng (a.k.a. Dr. Z), an Assistant Professor of Social Justice Education in the Department of Student Development at the University of Massachusetts College of Education, mentions, Chili peppers and capsaicin consumption reduce body weight and its potential mechanisms of anti-obesity effects.

Eiby gave the product 5 out of 5 stars and said, This stuff is great! After a couple weeks of consistent use I noticed my mood and energy at work has improved. Also gives me great pumps at the gym.
Ryan gave the product 3.0 out of 5 stars. He said, I haven’t received a significant increase in any area yet, but I am going to try it for one more month to see if I notice a difference. Zero negative side effects and I’m also pretty used to stimulants, so I may just not have as pronounced an effect.
An Amazon Customer gave 1.0 out of 5 stars. They said, The only effect is powerful diarrhea! I’ve been using VitBoost L-Arginine, extra strength, for a month. Whether I take one pill 3 times a day or three pills 1 time a day, all that happens is that I get immediate diarrhea! Also, I never received my free 30-day supply, which at this point, I would not use anyway. I’m not giving up on L-Arginine, just this brand. If anyone has a recommendation for another brand of L-Arginine, please pass it along.
