Dr. Robert Corish, AstaReal’s global medical advisor, explained, “This trial evaluated the most common type of fatigue that most of us experience during our daily routines—both mental fatigue and physical fatigue. The results show that AstaReal astaxanthin suppresses and fights both types of fatigue and improves performance. Fatigue is the most common complaint heard by physicians today; and in my experience, this is the first time that a natural ingredient has been shown to improve this common condition.”
In this double-blind, placebo-controlled study, individuals consumed AstaReal astaxanthin twice daily for eight weeks. The study was designed to induce fatigue and stress, similar to that encountered in daily life. For the mental challenge, individuals had to perform a battery of timed calculations—the Uchida-Kraepelin test—which evaluates concentration and mental clarity. The physical component was performed using a bicycle ergometer. Both subjective and objective metrics of fatigue were assessed both before and after the stressor tests.
Visual Analogue Scale (VAS) analysis showed that AstaReal astaxanthin significantly reduced perceived symptoms of mental and physical fatigue compared to the placebo. These included improvements in cognitive acuity, concentration, motivation and mood. Irritation and feeling of body heaviness were noticeably reduced. In the calculation test, an increase in errors observed in the placebo during the second half of the test was almost non-existent in the astaxanthin group. Supplementation with astaxanthin also significantly reduced salivary cortisol, a biomarker of stress.
Arun Nair, CEO at AstaReal USA, stated, “Everyone can benefit from increased physical and mental energy. Supplements containing AstaReal astaxanthin can improve daily lives by supporting physical endurance, sustained concentration, decision-making, memory, and motivation. Anyone performing under high levels of physical or mental stress, including educators, healthcare providers, financial professionals, and athletes, along with women in pre-menopause can harness the power of AstaReal astaxanthin to combat fatigue.”
