Excalibur is a fat-burner by Medi-Evil nutrition.
It’s designed to increase fat loss and energy levels while dieting.
Medi-Evil Nutrition is a supplement company from the UK. They produce a variety of products from protein powders to pre-workouts and fat-burners.
Green Tea is well-known for its fat-burning effects, and its extract is a common ingredient in weight-loss supplements.
Research has shown that Green Tea Extract can boost fat oxidation by 17% (1).
It may also improve insulin sensitivity which can be great for supporting lean mass.
The effective dose is 400-500mg.
Bitter Orange is a hybrid citrus fruit.
The key compound in it is Synephrine, which can be used to suppress appetite and improve weight loss.
Studies have demonstrated increases in calorie burning via metabolic rate with Bitter Orange supplementation. This was maximised with 6-12 weeks of using the extract (2).
Caffeine and Guarana
Guarana is another source of caffeine, and also has antioxidant properties.
The effective dose for caffeine is about 200-500mg. This can vary between individuals.
L-Tyrosine is an amino acid that reduces stress hormone production.
Research has shown it can improve mood and cognition under stressful conditions (5), making it helpful to take in a hungry or tired state.
An effective dose is 500-2,000mg.
L-Carnitine is a compound used in energy metabolism.
It may only be effective for fat-loss in people who are deficient.
In people without a deficiency, it can still increase insulin sensitivity and lower blood glucose levels, which is great for supporting a lean body composition (6).
A standard dose is 500-2,000mg.
Capsicum contains pigment compounds that have been shown to limit the metabolism of other substances (7).
This could improve the effects of other ingredients in the formula by enhancing absorption.
