Thin evidence: Respiratory infections (yeast) (grade C).

The evidence in words

The verdict

For respiratory infections (yeast), Beta-Glucans earns evidence grade C (small effect, mixed consistency) — the evidence is limited or mixed. Immune priming

How it might work

Oat beta-glucan forms a viscous gel that binds bile acids (lowering LDL) and blunts glucose; yeast/mushroom beta-glucans prime innate immune cells.

How to use it

3 g/day oat beta-glucan for cholesterol; standardized yeast/mushroom beta-glucan for immune support.

Safety & cautions

Very safe; gas/bloating with the soluble-fiber form.

Bottom line

Know which one you want: oat beta-glucan for LDL and glucose (well-proven), yeast/mushroom beta-glucan for modest immune support.

How it is used

As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.

Cholesterol: 3 g/day oat beta-glucan.
