Most fibers focus only on regularity. LOAM combines six clinically chosen prebiotics that work across digestion, energy, immunity, and metabolism — all in an invisible, tasteless formula.

No artificial sweeteners, no sugar alcohols, no added sugars, no preservatives, no fillers, and no cheap commodity fibers.

Every batch is third-party tested for purity, potency, microbial safety, heavy metals, and Low-FODMAP compliance.

Mix one scoop into 10–12 fl oz of water or any liquid, stir, and let it sit for 60 seconds before drinking.
