MCT oil Pure C8 (caprylic)

Also called mct, medium chain triglycerides, caprylic acid and 2 more

C8 oil, C8 mct.

The best price per 10 g MCT (C8 + C10) and per month across 1 UK retailer, and where to buy it cheapest. A unit for comparing, not advice.

Comparing MCT oil

We count the MCT (C8 + C10) a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. MCT oil comes as MCT oil (C8 + C10) and pure C8 (caprylic), and each form has its own table, because someone buying one would not usually take another as a like-for-like substitute. Products that combine MCT oil with other ingredients are listed separately, because their price buys more than MCT (C8 + C10). 10 g is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

Prices last checked: . Ranked purely by price per 10 g MCT (C8 + C10) — a comparison unit, not a recommendation. We earn commission when you buy through these links; it never affects the order.

By shop

Each shop's MCT oil products, with where its cheapest sits in the market.

How we work out these prices

We count MCT (C8 + C10) — the components stated on the label — not the weight of the oil. A 1,000 mg capsule of oil can contain very different amounts of MCT (C8 + C10). Products that state only the oil weight are left out until the content is confirmed.
