Exogenous ketones help the body to ‘think’ that it is in a ketosis state, even if you are still consuming carbohydrates. The most common exogenous ketones supplement is BHB (Beta-Hydroxybutyrate). During ketosis, the liver naturally produces BHB, which has 2 roles in the body. The first, is to signal the body to start metabolising fats for energy, lower blood glucose and essentially transition into ketosis. The second, is to act as a precursor for a ketone, which can be used for energy.
The benefits for taking exogenous ketones are:
- Help the body transition into ketosis easier, which can help avoid the ‘groggy’ feeling you experience when transitioning through diet alone.
- Improve mental clarity (largely achieved by the lowering blood sugar and the use of ketones as an energy source).
- Help with weight management/ weight loss.
There are also potentially many other benefits to BHB, which include cardioprotective, and anti cancer potential, although reserach in these areas is limited.
Do exogenous ketones work?
In short – yes. There is quite a lot of evidence that taking BHB does help with the transition into ketosis. There is also evidence that taking BHB without the highly restrictive diet (i.e, still eating carbohydrates) can have the same health benefits as being in ketosis, which is quite remarkable. Interestingly, although BHB does work in isolation, the research shows that it is most effective when taken alongside MCTs. MCTs compliment BHB very well because although they are a type of fat that is very easily metabolised into ketones, and ultimately energy. You can read the research in more detail here.
Where to buy exogeneous ketones in the UK?
Exogenous ketones are a new and niche product, and so are not that easy to find in the UK. Fortunately, we stock 2 brands of exogenous ketones: Perfect Keto, and Keto Sports, both of which offer a BHB in different flavours and forms (liquid/ powder), and also MCTs. You can view the range of BHB products here, and the range of MCTs here.
Both Perfect Keto and Keto Sports have their products 3rd part tested for purity, and so you can be confident on their quality.
