Buying Guide

Choose the right MCT type

C8 (caprylic acid) offers faster ketone production and is preferred for cognitive and ketogenic support, while C10 (capric acid) provides a slower energy release—look for labels that state C8/C10 ratios

Decide oil vs capsule

Liquid MCT oil (32 oz or 16 oz sizes common) is economical and flexible for coffee or recipes; capsules (e.g., 3000 mg per serving formats) offer convenience and precise dosing without measuring

Verify sourcing and purity

Opt for products listing organic coconut sourcing, third-party testing, and minimal additives to reduce contaminants and ensure an odorless, flavorless experience when desired

Match serving size to goals

Start with small servings to assess tolerance; higher-concentration C8 products and concentrated servings may enable lower milliliter doses for similar effects

Consider value and bottle size

Compare cost per serving across common sizes (e.g., 16–32 oz oils or multi-hundred softgel counts) to find budget options under $50 or larger formats for longer supply
