Beta-Glucans vs LL-37
Both are used for immunity. Here's how they compare on human evidence, mechanism, safety and availability — in plain English.
| Beta-Glucans | LL-37 | |
|---|---|---|
| Human evidence | ★★★☆☆ | ★★☆☆☆ |
| Legal status | OTC Supplement | Not Approved |
| How it works | Fungal/yeast polysaccharides bind Dectin-1 (CLEC7A) and CR3 on innate immune cells, priming trained immunity. | Human cathelicidin (CAMP gene) antimicrobial peptide; disrupts microbial membranes and modulates immunity/wound healing. |
| In plain English | Sugars from yeast/mushrooms that "train" your first-line immune cells to respond faster. Good evidence for reducing upper-respiratory infections. | A natural antibiotic your own body makes; explored for infections and healing. Very early for supplemental use. |
| Bottom line | Best-evidenced immune polysaccharide. | Interesting antimicrobial biology; minimal human supplement data. |
| Availability | Available over the counter | Not widely approved |
Which is better for immunity?
Beta-Glucans has the stronger human-evidence rating (★★★☆☆ vs ★★☆☆☆), but the right choice still depends on your goal, tolerance and budget.
