Muscle Boost X Review
Muscle Boost X ingredients

Muscle Boost X uses three different forms of arginine to promote nitric oxide production.

Muscle Boost X Ingredients

Muscle Boost X features three unique types of arginine that are claimed to maximize nitric oxide production and enhance your pumps in the gym.1

Below, we break down how these ingredients interact in the body and how they may contribute to enhanced sports performance.

L-Arginine Alpha Ketoglutarate – Arginine is a conditionally essential amino acid that acts as a building block for proteins. In the body, arginine is directly converted into nitric oxide, which increases vasodilation and improves blood flow.2 Alpha ketoglutarate (AKG) is an intermediate in the Krebs (energy) cycle and the nitrogen-free component of glutamine.3,4 AKG is used by the body to grow and heal cells, particularly muscle tissue. It has been noted to help prevent muscle wasting in post-surgery patients. It’s speculated that combining arginine and AKG (also known as AAKG) in a salt form can enhance blood flow, boost energy and help recovery time between training.3

L-Arginine – Beyond nitric oxide production, arginine is required for the formation of creatine, the release of growth hormones and the production of urea, an excretory substance.2 L-arginine has been shown to improve circulation and exercise tolerance in individuals with type 2 diabetes and cardiovascular diseases.2

L-Arginine Monohydrochloride – Added to supplements to help increase the absorption of nutrients, l-arginine a monohydrochloride is a white, crystalline salt of amino acid.

L-Citrulline – A non-essential amino acid, citrulline is one of three amino acids used in the urea cycle, which helps remove ammonia from the body. In the kidneys, citrulline is converted into arginine and is more effective at increasing plasma levels than arginine itself. Citrulline can be supplemented to help delay fatigue, alleviate symptoms of erectile dysfunction and improve aerobic and anaerobic endurance. According to clinical studies, successful citrulline doses have started at 6g.5

Dipotassium Phosphate –Marketed to improve athletic performance, dipotassium phosphate is the combination of phosphate and the mineral potassium.6 Phosphates are essential chemicals that contribute to energy production and allow proper vitamin uptake and function.6 Dipotassium phosphate may also act as an electrolyte, which is important for maintaining fluid balance.7

How to Use Muscle Boost X

According to the Muscle Boost X label, users should take two capsules by mouth 1-2 times daily.

Muscle Boost X Side Effects

While many of the Muscle Boost ingredients are naturally occurring, they still have the possibility to cause adverse reactions or interact with medication.

Below, we have evaluated the ingredients and doses used to compile a list of possible Muscle Boost X side effects.

Phosphate salts draw more fluid into the intestines and stimulate bowel movements. This may irritate the digestive track and cause an upset stomach, diarrhea or constipation. When taken for extended periods of time, phosphate salts may alter the body’s natural phosphate and chemical balance.7 Arginine may lower blood pressure through increased vasodilation. For some users, arginine may cause a change in blood sugar or nausea. In rare cases, arginine may cause an allergic reaction, increase the risk of bleeding, or cause changes in vision.4

Individuals with heart disease, kidney disease, thyroid conditions, hypercalcemia or liver disease should avoid taking supplements with phosphate salts as it may aggravate these conditions or cause blood phosphate levels to become too high.7

Muscle Boost X Projected Results

Based on the quantity of ingredients, a review of current scientific studies, and consumer reviews, below are the projected results for Muscle Boost X.

Users who do not consume enough protein may have low levels of arginine within the body.9 Increasing arginine levels through supplementation may provide an increase in blood flow, ammonia recycling, protein synthesis and nitric oxide production. This may be useful when combined with a training routine. According to Health Canada, the Canadian national health authority, the minimum dose of arginine used in clinical trials has been 3 g.2 This is significantly more than the total serving size of Muscle Boost X.

On the website, Muscle Boost X doesn’t advertise any awards, independent certifications, before or after photos, customer testimonials or athlete endorsements. These factors add credibility to a product, particularly when it’s sold online. However, their absence does not suggest that Muscle Boost X is a scam or an ineffective product.

Where to Buy Muscle Boost X

Muscle Boost X is exclusively available online and are currently not carried by major sports nutrition retailers. For the price of shipping and handling, users receive a full 30-day supply of the product, and can try it before deciding if they would like to continue using it.
