Nutramunity® Beta-Glucan (Yeast Beta-Glucan)

Saccharomyces cerevisiae
Evidence Level
Limited
0 Clinical Trials
3 Documented Benefits
2/5 Evidence Score

Nutramunity® Beta-Glucan is a beta-1,3/1,6-glucan from the cell walls of baker's yeast (Saccharomyces cerevisiae), a well-studied class of immune-supporting fibers. Yeast beta-glucan is taken to support the body's natural immune defenses. Dedicated published data for this specific brand are limited.

Studied Dose Commonly around 75 to 250 mg per day.
Active Compound Yeast (Saccharomyces cerevisiae) beta-1,3/1,6-glucan.

Benefits

Immune support

Yeast beta-1,3/1,6-glucan is studied for priming the innate immune system, supporting the body's natural defenses against everyday challenges.

Respiratory wellness

Beta-glucans are studied for supporting resistance to upper-respiratory challenges, of interest during cold season.

Limited-evidence note

Yeast beta-glucan has supportive research as a class, but dedicated published clinical data for this specific brand are limited.

Mechanism of action

1

Innate immune priming

Beta-1,3/1,6-glucan is recognized by immune-cell receptors (such as Dectin-1) that prime the innate immune system to respond more readily.

2

Macrophage activation

Yeast beta-glucan is taken up by gut immune tissue and supports the activity of macrophages and other first-line immune cells.

Clinical trials

Side effects and drug interactions

Common Potential side effects

Generally well-tolerated.
Mild digestive upset is occasionally reported.
Yeast-allergic individuals should check the source.

Important Drug interactions

No major drug interactions are established.
Immunosuppressant drugs — consult a doctor, as beta-glucan stimulates immunity.
Tell your doctor if you have an autoimmune condition.
