Buying Guide

Choose the right MCT type

C8 (caprylic) is favored for rapid ketone production, while C10 (capric) offers slower conversion; many formulas combine both for balance

Pick the form that fits your routine

Liquid oils work well in coffee and recipes, powdered MCTs mix into shakes, and softgels are convenient for dosing without taste

Check purity and source claims

Look for coconut-derived and organic labels if you prefer plant-sourced MCTs and minimal processing

Consider digestion and additives

Flavorless or unflavored oils minimize additives; powders may contain fillers or dairy alternatives that affect tolerance

Match serving size to goals

Higher-concentration C8 products suit cognitive or ketone-focused goals, while blended C8/C10 suits steady energy and general supplementation
