About the Brand
The manufacturer of Buck Naked is a sports nutrition company called Bucked Up, founded by current CEO Ryan Gardner in 2016. Headquartered in Orem, Utah, the organization’s mission is to help athletes and workout enthusiasts improve performance and meet their fitness goals.

How Does Buck Naked Work?
Buck Naked contains ingredients that help boost the metabolism, potentially putting the body into a fat-burning state called thermogenesis.
This can promote faster calorie burning, as we said in our review of Inno Shred, potentially leading to weight loss when combined with diet and exercise. Some of the ingredients offer stimulant benefits, helping to increase daytime energy and potentially boost activity levels.
In addition, Buck Naked has amino acids like l-theanine that help boost the synthesis of neurotransmitters like serotonin, dopamine, and GABA. This could help boost mood and decrease stress resilience, and some evidence indicates that serotonin may curb appetite.
Other Buck Naked ingredients may help improve glucose metabolism to support healthy blood sugar levels, potentially decreasing hunger and cravings.
Buck Naked Ingredients – Are They Safe & Effective?
Some of the primary active Buck Naked ingredients include:
Enfinity® Paraxanthine
This is the primary caffeine metabolite in the body, and it may potentially increase metabolism, speed up fat-burning, promote weight loss, and boost energy without as many of the side effects related to the use of this stimulant.
A study of adults published in the Journal of Dietary Supplements concluded that supplementation with paraxanthine improved energy expenditure and fat oxidation, but it increased hunger and had no impact on hemodynamics or lipolysis.
Acetyl L-Carnitine HCI
This form of l-carnitine is made naturally in the body, and it plays a key role in transporting fatty acids to convert fat into energy. While study results vary, it may help promote weight loss and boost energy levels. In addition, it could help improve cognitive functions like focus and attention.
A meta-analysis published in Pharmacology Research found that l-carnitine supplementation may help reduce weight and BMI in overweight or obese subjects.
Caloriburn GP® (Grains of Paradise Extract)
Derived from a plant in the ginger family, grains of paradise may help active brown adipose tissue. As we explained in our review of the Underground Fat Burner, this could help speed up fat-burning for potential weight loss. It may also help improve digestion and decrease inflammation.
A study published in the Journal of Nutritional Science Vitaminology found that supplementation with grains of paradise may help prevent visceral fat accumulation.
Cayenne Pepper
This pepper has the bioactive agent capsaicin which has some support for its potential to speed up the metabolism to help boost fat-burning and weight loss. In addition, it may decrease hunger and cravings. Cayenne supports heart health and could improve digestion.
A review published in Bioscience Reports discussed the potential anti-obesity benefits of dietary capsaicin.
L-Theanine
This amino acid increases the synthesis of the neurotransmitters serotonin, dopamine, and GABA, which could boost mood, improve stress resilience, and enhance cognitive function. It may also help decrease appetite, potentially supporting weight loss.
A study of mice on a high-fat diet published in Foods concluded that supplementation with l-theanine may help reduce some of the complications related to obesity.
How to Take Buck Naked?
The recommended dosage is 3 capsules daily with 6-8 ounces of water, taken 20-30 minutes before a workout or meal. Do not exceed this amount daily unless directed by a healthcare practitioner. In addition:
- Stay adequately hydrated throughout the day.
- Do not take the capsules within 6 hours of bed to avoid difficulty with sleep.
- Follow a healthy diet and exercise regularly along with usage.
