AstaReal: Astaxanthin may increase fat burning in active women
A new study suggests astaxanthin supplementation may enhance fat utilization for energy during exercise in women. The effect was observed after two weeks.
Swedish company AstaReal AB has reported findings from a new clinical study indicating that astaxanthin may increase fat burning during moderate exercise in active women. The study was published in the Journal of Dietary Supplements.
The research involved 20 recreationally active women who received either 12 mg of AstaReal® Astaxanthin or a placebo daily for two weeks. Subsequently, their respiratory exchange ratio (RER) was measured during a cycling test to assess fuel utilization. RER indicates the relative contribution of fat and carbohydrates to energy expenditure.
Results showed that participants receiving astaxanthin had a significantly lower RER compared to the placebo group, suggesting increased fat utilization. This occurred without any increase in heart rate, blood lactate levels, or perceived exertion. Behnaz Shakersain, Scientific Affairs Manager at AstaReal, stated that the findings point to more efficient energy utilization by the body.
Shakersain highlighted that previous research on astaxanthin in sports nutrition has largely focused on men. As women generally rely more on fat as a fuel source during physical activity, the observed increase in fat utilization with astaxanthin is particularly noteworthy. The study expands the understanding of astaxanthin's potential benefits for women in sports nutrition.
