What Are the Ingredients in Decaduro?

If you are curious about the Decaduro ingredients, we've broken them down in the following section.

Wild Yam Root

Because it contains diosgenin, wild yam may have effects similar to dehydroepiandrosterone (DHEA), which is a precursor to testosterone.⁽¹⁾ Therefore, it may support healthy testosterone levels, which promote muscle growth and improve athletic performance. Diosgenin has been shown to improve cognitive functioning in healthy adults.⁽²⁾ Diosgenin appears to improve cardiovascular health, prevent type 2 diabetes, and protect the brain from oxidative damage.⁽³⁾ The anti-inflammatory activity of wild yam may help decrease swelling and alleviate joint pain, which could result from a vigorous exercise regime.

Panax Ginseng

An all-around adaptogen that has been used for thousands of years, ginseng increases fertility, produces stronger erections, and improves your overall sexual performance.⁽⁴⁾ This herb not only improves your mood but also boosts your cognitive abilities.^(5)(6)(7) Ginseng reduces fatigue, improves blood flow, and boosts physical performance.⁽⁸⁾

L-Arginine Alpha-Ketoglutarate

L-arginine is a non-essential amino acid commonly used in bodybuilding and sports nutrition as a building block for muscle protein synthesis. Taking L-arginine has been shown to increase human growth hormone levels.⁽⁹⁾ In the human body, L-arginine converts into nitric oxide, an essential compound for a healthy heart and blood vessels,⁽¹⁰⁾ improving blood flow to muscles.⁽¹¹⁾

According to animal⁽¹²⁾ and human⁽¹³⁾ studies, L-arginine enhances muscle growth when combined with resistance and strength training. This effect may be due to increased myofibrillar protein synthesis in muscles triggered by L-arginine, which helps build lean body mass.⁽¹⁴⁾

Overall, L-arginine improves sports performance by increasing muscle protein synthesis and promoting muscle tissue repair.⁽¹³⁾ According to a recent systematic review and meta-analysis, L-arginine can improve anaerobic power and capacity, resulting in better performance during explosive and high-intensity, strenuous workouts.⁽¹⁵⁾

Acetyl-L-Carnitine

Acetyl-L-carnitine (ALCAR) is a form of L-carnitine, an amino acid synthesized in the body from lysine and methionine. ALCAR transports free fatty acids into the mitochondria, which allows the body to burn fat and release the energy stored in its fat reserves.⁽¹⁶⁾ This helps promote fat loss and maintain lean muscle mass. A recent systematic review and meta-analysis of 37 clinical trials has found that L-carnitine is effective for shedding weight, particularly via enhanced fat loss,⁽¹⁷⁾ especially in overweight individuals.⁽¹⁸⁾ L-carnitine also improves muscle strength and helps reduce muscle soreness and damage.⁽¹⁹⁾ In addition, L-carnitine improves body strength, sports endurance, and exercise capacity and delays the onset of fatigue.⁽²⁰⁾

L-Citrulline

L-citrulline is a dietary component and non-essential amino acid with a long history of use in bodybuilding. It augments L-arginine bioavailability and increase production of nitric oxide. Nitric oxide widens blood vessels to improve blood flow, which increases oxygen and nutrient delivery to muscle tissue.⁽²¹⁾ Research shows that supplementing with L-citrulline can improve both your resistance and endurance training.⁽²²⁾ L-citrulline also increases energy production, giving you more power and capacity.⁽²³⁾ L-citrulline significantly decreases perceived exertion and muscle soreness 24 and 48 hours after exercise.⁽²⁴⁾

Tribulus Terrestris

Tribulus terrestris is a plant from Ayurveda that has been used for centuries for male virility and general vitality. Tribulus extract has the potential to act as a natural testosterone booster. It aids in muscle recovery and may alleviate muscle damage.⁽²⁵⁾ Although the evidence for the Tribulus' ability to increase testosterone production is conflicting,⁽²⁶⁾ it does increase stamina and sex drive.^(27)(28)

How Does Decaduro Work in the Body?

Decaduro's anabolic formula promotes nitrogen retention. This allows the body to supply more protein to the muscles, giving you faster muscle gains and making your muscles stronger.

Additionally, you also get increased blood flow and more oxygen to supply muscle cells.

Decaduro is also a natural testosterone booster. Higher testosterone levels speed up the metabolism and help you get quality muscle gains.

What Are the Benefits of Using Decaduro?

Thanks to its science-backed ingredients, Decaduro has numerous health benefits.

Improved Metabolism

A better metabolism results in more energy, and Decaduro is a great supplement to help with that. You will be left with lean muscle mass due to increased muscle protein synthesis and increased strength gains as well.

You also don't have to worry about gaining weight, as all the calories you take in are used to build muscle mass!

Increased Immunity

Decaduro is also great for building up your immune system and protecting you from nasty bugs.

Your body becomes stronger and more resistant to external factors and infections.

Faster Recovery Time

Decaduro boosts nitric oxide production, which gets more oxygen and nitrogen flowing to muscle cells.

More oxygen and nitrogen lead to a shorter recovery time, so you are back in the game faster.

This allows you to increase your workout intensity and exercise longer and more efficiently without getting tired easily. You are literally less fatigued after an intense workout!

Repairs Damaged Connective Tissues

Joint pain or tendon pain due to excessive physical activity can be rough. Luckily, Decaduro can aid in the recovery process you need!

Decaduro stimulates collagen synthesis, which is what your tendons, ligaments, and bones are made of, and ultimately offers joint pain relief.

Increased Red Blood Cell Production

More red blood cells increases endurance and reduces fatigue during your workout sessions, allowing you to gain muscles much faster.
