The ketogenic diet has surged in popularity, leading to a proliferation of keto supplements promising effortless ketosis and amplified results. Among these, exogenous ketone supplements, like Ignite Keto, claim to provide an energy boost and support the keto lifestyle. This article delves into the science behind these supplements, scrutinizes their effectiveness, and explores safer, more evidence-based alternatives.
Understanding Ketosis and Exogenous Ketones
The ketogenic diet is a low-carbohydrate, high-fat diet designed to shift the body into a metabolic state known as ketosis. In ketosis, the body, deprived of its primary fuel source (carbohydrates), begins to break down fat for energy, producing ketones as a byproduct. These ketones then become the body's primary fuel source.
Exogenous ketone supplements are nutritional supplements designed to mimic this process. They contain beta-hydroxybutyrate (BHB), one of the primary ketones produced by the body. These supplements come in two main forms:
- Ketone salts: BHB bound to a mineral, such as sodium, potassium, calcium, or magnesium.
- Ketone esters: BHB bonded to another compound called an ester, typically packaged in liquid form. Ketone esters are considered more potent.
Ignite Keto and Similar Products: A Closer Look
Ignite Keto, along with products like Keto Drive and PK BHB Base, are marketed as premium ketone supplements. Zhou Nutrition, the company behind Keto Drive, is a Utah-based company founded in 2014. These products generally claim to offer benefits such as increased energy, improved mental clarity, and enhanced fat burning.
- Ingredients and Nutritional Information: Each container typically offers around 16 servings, with a minimal caloric content (around 5 calories per serving, although this may be a labeling error, as BHB ketones contain around 4-7 calories per gram). These products are often gluten-free and contain zero carbs. Ignite Keto and Keto Drive both contain caffeine, while PK BHB Base is caffeine-free.
- Cost: Ignite Keto tends to be the most expensive, at around $5.88 per ounce.
The Truth About Exogenous Ketone Supplements: Separating Fact from Fiction
The allure of exogenous ketones lies in the promise of achieving ketosis without strict dietary adherence. However, several myths surround these supplements.

- Myth #1: Exogenous ketones guarantee ketosis. While they do raise blood ketone levels, exogenous ketones don't necessarily create the metabolic environment needed for sustained ketosis. The body needs to undergo physiological changes, such as glycogen depletion and insulin reduction, to efficiently produce ketones on its own. Supplementing bypasses this process, potentially hindering long-term adaptation to ketosis.
- Myth #2: Exogenous ketones ignite fat burning. In reality, these supplements can temporarily suppress fat burning. When you consume exogenous ketones, the body uses them for fuel, reducing the need to break down stored fat. This, in turn, can temporarily shut down the body's own ketone production until the consumed ketones are used up.
Potential Benefits of Exogenous Ketones (and When They Might Be Useful)
Despite the myths, exogenous ketone supplements may offer some benefits in specific situations:
- Appetite suppression: Research suggests that ketone ester supplementation may lower ghrelin levels (the hunger hormone), reduce perceived hunger, and decrease the desire to eat for up to four hours.
- Exercise performance: Some studies indicate that taking a BHB ketone ester with carbohydrate before exercise may provide a small increase in performance.
- Cognitive function: Case reports, small trials in athletes, and animal studies suggest that exogenous BHB may improve cognitive performance.
- Specific health conditions: Research suggests that ketosis may be helpful for managing certain conditions like cancer, Alzheimer's disease, Parkinson's disease, type 2 diabetes, and epilepsy.
Therefore, the following groups may find benefits from using exogenous ketone supplements:
- Keto-adapted endurance athletes.
- People who are struggling with keto induction.
- People who have health conditions that benefit from ketosis but cannot stay on the keto diet for any reason.
The Downsides: Risks and Side Effects
- Gastrointestinal distress: The consumption of exogenous ketone supplements can provoke some keto flu symptoms like fatigue, headaches, dizziness, cramping, diarrhea, constipation, and heart palpitations.
- Cost: Ketone salts are your cheapest option, but they will still break most budgets at around $60 for just 16 servings.
- Hidden Ingredients and Safety Concerns: It is important to note that the FDA does not approve dietary supplements for safety or efficacy, and ingredients and their amounts may vary. Numerous weight loss supplements have been found to contain hidden and potentially harmful drug ingredients.
A Safer, More Effective Alternative: MCT Oil
Fortunately, there is a ketone-boosting supplement that actually supports ketosis and ignites fat burning: MCT oil. MCT stands for medium chain triglycerides - a type of saturated fat that skips the normal digestive process of other fats. This influx of MCTs into the liver mimics the process that occurs when fatty acids are released from our fat cells and enter the liver during carb restriction. By supplementing with MCTs rather than exogenous ketones, you are giving the liver the substrates it needs to jump start ketosis without shutting down ketone production.
The research on MCT supplementation is more extensive and convincing than what we’ve found to support exogenous ketones as well. Overall, the research indicates that MCTs are equally, if not more, beneficial than exogenous ketone supplements. However, as with ketone salts and esters, digestive issues can occur when supplementing with too many MCTs. For this reason, it is best to start with a small amount (1-1.5 teaspoons) and increase day by day until you work up to a 1-4 tablespoon dose.
Taste and Palatability
Taste is a significant factor when considering any supplement. Some find the taste of ketone supplements unpalatable, describing it as similar to "radioactive waste." However, some flavors receive positive reviews. For example, Chocolate stands out as a customer favorite. One reviewer even compared it to the Orange Tang drink.
