Ability of a Euglena Beta Glucan Supplementation to Augment Immune Function

2018-05-14 16:58:19 | BioPortfolio


Upper respiratory tract infections cause cold and flu-like symptoms and are the most common form of acute illness. Certain populations are at increased risk of upper respiratory tract infections including athletes who train at a high level of intensity for prolonged periods of time. Consequently, some athletes experience higher rates of cold and flu-like symptoms than the general population.

Euglena gracilis is a micro-algae which can synthesize many nutrients necessary for human health, including insoluble beta glucan. Thus, intake of whole cell Euglena may be beneficial to athletes by providing essential vitamins to optimize immune function.


At screening, an informed consent form will be given to the potential volunteer. They will be required to read the information and be given the opportunity to seek more information if needed, or provided with the option of taking the consent form home to review prior to making their decision. If agreeable, the volunteer will sign the consent form and receive a duplicate of the signed copy. Once consent has been obtained, the screening visit will proceed.

Screening assessments include:

1. Review of medical history, concomitant therapies and current health status (weight, height, BMI, vital signs, safety blood work)

2. Assesses inclusion and exclusion criteria

3. Urine pregnancy test for female potential participants that are not post-menopausal

Eligible participants will return to the clinic for baseline assessments. Baseline (day 0) assessments include:

1. Review of concomitant therapies and current health status

2. Review pre-supplement emergent AEs

3. Reassess inclusion and exclusion criteria

4. Randomization of eligible participants

5. Dispense daily upper respiratory tract symptom questionnaire

6. Collect saliva sample for measurement of secretory IgA

7. Collect blood sample for the analysis of cell activity

8. Administer mood and stress questionnaire in-clinic

9. Dispense daily gastrointestinal and bowel questionnaire

10. Dispense investigational product and instruct participants on use

11. Dispense daily study diary

At the end-of-study visit (Day 90) participants will return to the clinic for Visit 3 assessments with unused investigational product, completed study diaries, daily symptom questionnaires, daily gastrointestinal and bowel diaries.

Visit 3 assessments include:

1. Collection of all study diaries

2. Return of unused investigational product and calculate compliance

3. Review of concomitant therapies and adverse events

4. Check of health status (vitals, BMI, safety bloodwork)

5. Administer mood and stress questionnaire in-clinic.

6. Collect saliva sample for an end-of-study measurement of secretory IgA

7. Complete Product Tolerability and Perception Questionnaire

Medical and Biotech [MESH] Definitions

An exocellulase with specificity for 1,3-beta-D-glucasidic linkages. It catalyzes hydrolysis of beta-D-glucose units from the non-reducing ends of 1,3-beta-D-glucans, releasing GLUCOSE.

An exocellulase with specificity for the hydrolysis of 1,4-beta-glucosidic linkages of 1,4-beta-D-glucans resulting in successive removal of GLUCOSE units.

An endocellulase with specificity for the hydrolysis of 1,3-beta-D-glucosidic linkages in 1,3-beta-D-glucans including laminarin, paramylon, and pachyman.

In glycogen or amylopectin synthesis, the enzyme that catalyzes the transfer of a segment of a 1,4-alpha-glucan chain to a primary hydroxy group in a similar glucan chain. EC

1,4-alpha-D-Glucan-1,4-alpha-D-glucan 4-alpha-D-glucosyltransferase/dextrin 6 alpha-D-glucanohydrolase. An enzyme system having both 4-alpha-glucanotransferase (EC and amylo-1,6-glucosidase (EC activities. As a transferase it transfers a segment of a 1,4-alpha-D-glucan to a new 4-position in an acceptor, which may be glucose or another 1,4-alpha-D-glucan. As a glucosidase it catalyzes the endohydrolysis of 1,6-alpha-D-glucoside linkages at points of branching in chains of 1,4-linked alpha-D-glucose residues. Amylo-1,6-glucosidase activity is deficient in glycogen storage disease type III.
