Overview

This is a liquid MCT oil concentrated in caprylic acid (C8), pressed from non-GMO coconuts, sold in a 14 fl oz bottle with no added flavor. It fits a keto or low-carb routine where the goal is a quick source of fat calories rather than a full meal.

C8 is one of several medium-chain triglycerides found in coconut oil, and it's the fraction most often linked to a faster conversion to ketones than standard coconut or MCT blends. The bottle carries no flavoring, so taste and texture come through as a plain oil, and some people find that harder to tolerate on an empty stomach than flavored versions.

  • 14g of MCTs per serving
  • 14 fl oz bottle
  • Non-GMO coconut source
  • Gluten free and soy free

Who it's for

Suits people already following a ketogenic or intermittent fasting plan who want a mixable oil for coffee or shakes. Not for anyone looking for a flavored or capsule format, or anyone new to MCT oil who hasn't built tolerance gradually.

Pros and cons

Pros
  • Concentrated C8 fraction rather than a general MCT blend
  • Unflavored, so it mixes into coffee or food without altering taste
  • Non-GMO and free of gluten and soy
Cons
  • No flavor options if you dislike the taste of plain oil
  • High-C8 oils can cause GI discomfort at high starting doses

Performance notes

MCT oils are absorbed and processed differently from long-chain fats, going more directly to the liver for energy conversion, which is the basis for the sustained-energy claim on keto diets. Starting with a teaspoon and working up is the common approach, since larger doses of straight C8 oil can cause loose stools in people unaccustomed to it.
