MCT Oil: Reviewing the Evidence
With the popularity of ketogenic diets and the ‘bullet-proof’ coffee regime, one food which appears to be gaining popularity in the weight loss arena is MCT Oil. In this post I aim to review the research behind MCT and how helpful it may actually be.

WHAT IS MCT OIL?

MCT stands for Medium Chain Triglycerides – a type of fat which is low in our diets, and which has had a lot of interest in recent years. Generally, MCT oil is sourced from coconut oil.

MCT OIL vs. COCONUT OIL

Generally, coconut oil contains MCT’s combined with other long chain fatty acids, making coconut oil an extremely healthy and stable cooking oil. MCT oil has had these other longer chain fats removed, increasing the provision of MCT’s. There are 4 different MCT’s – Caproic, Caprylic, Capric and Lauric. Caprylic and Capric are considered to be excellent sources of energy. (1) MCT oil is better than coconut oil as a source of MCT’s, since it contains higher amounts of caprylic and capric acid.

WHAT ARE THE CLAIMS

MCT oils are easily digested and sent to the liver, where they are used as an energy source – boosting metabolism and helping the body burn fat more effectively. (1) This in turn is supposed to help support weight loss and fat burning.

The brain is also said to be able to make use of the energy provided by MCT’s, with many people claiming that MCT oil could be helpful for brain function and memory.

WHAT DOES THE RESEARCH SAY?

FOR BRAIN FUNCTION: Published clinical trials have indicated that supplementing MCT oils will provide the brain with the fuel it requires, and could be a useful addition to regimes aimed at memory problems and those worried about Alzheimer’s. (2)

FOR WEIGHT LOSS: Studies have suggested that MCT oils could help to reduce tummy fat by promoting ketogenesis (fat burning). Other investigations have shown that these oils help to reduce body mass and increase metabolism as well as potentially reducing appetite. (3,4,5)

HOW TO USE MCT OIL

Many advocates of MCT oil suggest adding it to black coffee, smoothies or shakes. It may cause a feeling of nausea initially, so starting with a small amount and working up to the suggested dose (1 tablespoon) is probably best for those who do want to give it a go.

Vitamin K: -What is it?

The two most important forms found in food are vitamin K1 (phylloquinone) and Vitamin K2 (menaquinone).

K vitamins are a group of fat-soluble vitamins. The two most important forms found in food are vitamin K1 (phylloquinone) and Vitamin K2 (menaquinone). Vitamin K1 is known for its role in blood coagulation (clotting). Vitamin K2 also contributes to coagulation, but more importantly, it is a form newly recognized for its essential role in building and maintaining strong bones, as well as inhibiting calcium deposits in the arteries and blood vessels.

Supplemental Vitamin K2 exists in several forms, but the most common ones are the synthetic menaquinone-4 (MK-4) and the natural and nature-identical synthetic menaquinone-7 (MK-7).

MK-7 is the superior form of vitamin K

All K vitamins are similar in structure, but differ in the length of the “side chain” – the longer the side chain, the better effect and efficiency. Consequently, the long-chain menaquinones (especially MK-7) are the most desirable as they are nearly completely absorbed (body requires smaller doses) and stay in the blood for the longest time. This makes Vitamin K2 also available for tissues outside the liver, namely bones, arteries, and soft tissues.

In fact, studies consistently show that Vitamin K2 as MK-7 is much more effective compared to MK-4. This is mainly due to MK-7’s significantly greater:

  • Absorption & Half-Life Time
  • Accumulation in the Serum
  • Efficacy

Absorption & Half-Life Time

Both Vitamin K2 as MK-4 and MK-7 are nearly completely absorbed, with peak serum concentration at 2 hours for MK-4 and 4 hours for MK-7 after intake. However, MK-4 quickly disappears from the circulation, whereas MK-7 is capable of accumulating in the bloodstream (remaining in the body for approximately 72 hours). Therefore, supplementation with MK-7 only needs to be taken once a day and is a more convenient option.1

Accumulation in the Serum

The long half-life of MK-7 results in significantly better accumulation compared to MK-4. Research shows that  MK-7 has  better absorption. Hence, smaller quantities and less frequent intakes of MK-7 are sufficient to supply all of the tissues.2

Efficacy

45mcg/daily of MK-7 is proven to be sufficient in order to increase the carboxylation process and the activation of vitamin K-dependent proteins such as Osteocalcin for bone health and Matrix Gla Protein (MGP) for heart health.3
