Beta-Glucan: effective % & pH 베타글루칸

Quick answer: Beta-Glucan: effective concentration varies (typically ~0.1–0.5% active; some essences much higher base %), optimal pH 4.5–7.0, evidence Moderate. Beta-glucan works at very low concentrations, so a small active % is fine; a big headline number usually reflects a watery base, not extra potency.

What the % on the label really means

Beta-glucan works at very low concentrations, so a small active % is fine; a big headline number usually reflects a watery base, not extra potency.

⚠️ Ceiling: Effective at low active levels; a high listed % is often the diluted solution, not pure beta-glucan.
