Supplementation With Algae May Help Reduce Effects of Stress

Euglena is a freshwater species of single-celled algae that contains abundant nutrients, such as vitamins, minerals, amino acids, and fatty acids. A recent study suggests that supplementation with euglena may help reduce stress and improve sleep quality.

Eighty adults with an average age of 42 participated in the study. They were given 500 mg of Euglena powder, 1,000 mg of Euglena powder, 3,000 mg of Euglena powder, or a placebo daily for 12 weeks. The Uchida-Kraepelin test was administered at week 4, week 8, and week 12. This test is used to induce mental stress. The researchers evaluated the autonomic nervous system, psychological state, and sleep quality prior to the test, immediately after the test, and 60 minutes after the test.

The researchers found that the 1,000 mg dose was most effective in regulating the autonomic nervous system. The autonomic nervous system regulates things such as blood pressure, heart rate, body temperature, and metabolism. All three Euglena groups saw significant improvements in sleep quality. The biggest improvements were seen in the 3,000 mg group. Participants in all three Euglena groups also saw decreases in irritability and tension.

The study was conducted by researchers from the Miura Clinic. It was published online ahead of print on October 23, 2020 in the journalNutrients.
