Vegemite and peanut butter were already top tier spreads but have reached new levels thanks to a recent study.
Research published in the European Journal of Nutrition says that both Vegemite and peanut butter are packed full of biotin — a water-soluble vitamin — which is needed for muscle building, as reported by Men’s Health.
In the research, scientists specifically pointed to a biotin-filled product called Marmite Crunchy Peanut Butter — a popular spread from the United Kingdom that is a combination of both products and isn’t currently sold in Australia. But, as Men’s Health pointed out, Vegemite is just as yeasty as Marmite (which is where the biotin comes in), so it still counts.
The combination of Vegemite and peanut butter naturally increases the levels of IGF-1 in your body. This is a growth hormone that helps stimulate muscle gain and repair, while also improving your endurance levels.
According to Men’s Health, IGF-1 is so effective in its ability to grow muscles that it’s actually banned in its synthetic form by the World Anti-Doping Agency.
While you probably won’t be competing in any bodybuilding competitions anytime soon, chowing down on Vegemite and peanut butter toast will help you in your gym training.
Biotin also helps amino acids to carry out normal functions in your body, says Healthline, and can reduce inflammation, improve cognitive function and help lower blood sugar levels for those with diabetes.
