Exogenous ketones are a beneficial supplement for people on the low-carb, ketogenic diet. On keto, you limit your carb intake to 50 grams or less per day and base your meals on healthy fats and moderate amounts of protein instead. Once your on-board carb levels are depleted – a process that takes anywhere from a few days to two weeks – your body starts preferentially burning fat. The result? Fast, easier fat loss.
Using exogenous ketones can make the keto diet more effective and comfortable in several different ways. Exogenous ketones artificially elevate the ketone levels in your body to accelerate fat burning, reduce the severity and duration of the so-called keto flu, give you energy, and can even help ward off hunger. If you are serious about getting more from the keto diet, exogenous ketones really can help.
With so many exogenous ketone products to choose, it can be hard to know where to start. Use this guide to help you get the best exogenous ketones for you.

Read moreKeto Trim is an exogenous ketone supplement made by Nature-Driven. Unlike many exogenous ketone products, this supplement contains raspberry ketones instead of BHB ketone salts.
Key Features
- 800 mg of raspberry ketones per serving
- Contains several proven fat-burning ingredients
- Easy to use capsules
While Keto Trim might help you lose weight, it won’t be through boosting ketosis. Raspberry ketones are not “real” ketones and have no impact on ketosis. The other ingredients in Keto Trim may enhance fat loss and include green coffee bean extract, caffeine anhydrous, and garcinia cambogia. However, the main ingredient in this product is all-but inert and won’t help you lose weight.
Pros
- Increased energy
- May reduce hunger
- Increased metabolism
Cons
- Raspberry ketones are much less effective than BHB ketone salts
- High caffeine content
Keto Trim is not a good source of exogenous ketones. Raspberry ketones are similar to “real” ketones, but similar is not close enough. Your body does not recognize and cannot use raspberry ketones. The other ingredients may enhance fat loss, but the main substance in this product is a bust.

Read more7-Keto by Nutrigold is a weight loss supplement that contains the compound 7-keto-dehydroepiandrosterone, or 7-Keto-DHEA for short. However, despite having the word keto in its name, this is not an exogenous ketone product, and nor does it have to be used alongside the ketogenic diet.
Key Features
- 7-Keto-DHEA is a precursor of thyroid hormone
- Cellulose (vegetarian-friendly) capsules
- Proven ingredient
Despite not being a source of exogenous ketones, Nutrigold 7 Keto could still help you lose weight. 7-Keto-DHEA has been shown to increase metabolic rate, boost muscle mass, increase thermogenesis, and also reduce cortisol levels. It’s also good for your general health and may even help reduce the effects of aging.
Pros
- Proven ingredients
- Easy to use
- Suitable for vegetarians and vegans
Cons
- Will not affect ketosis
- 7-Keto-DHEA is a legal prohormone but could lead to a failed drugs test in sports
Despite not being an exogenous ketone product, Nutrigold 7 Keto could still help you lose weight. However, without those crucial ketones, it won’t enhance any aspect of ketosis or the ketogenic diet.
Conclusion
Using exogenous ketones on keto can make many aspects of low-carb dieting easier to live with. Taking exogenous ketones artificially increases your ketone levels, and that can help reduce the duration and severity of keto flu, reduce hunger, boost your energy levels, and speed up fat loss.
While this means that exogenous ketones are very popular, they can also cause some side effects. Stomach upsets are the most common problem with this type of product, and headaches are a close second. However, in most cases, simply using less than the recommended dose will prevent these problems.
Should you use an exogenous ketone drink mix, capsules, or liquid? And are pure exogenous ketone products better than blends that contain additional ingredients? The answer to these questions is it depends.
Ketone drink mixes contain a lot of ketones but often have an unpleasant taste. Capsules bypass the taste problem, but you won’t get as many ketones per serving. And as for caffeine, it all depends on when you want to use your exogenous ketone supplement. If you think you might use it at night, caffeine is best avoided. Exotic added ingredients could help you on your weight loss journey, but they may also mean that your chosen product contains fewer ketones.
Finally, remember that even the best exogenous ketone product won’t work if you aren’t doing keto right. But, if you are following a strict ketogenic diet, exogenous ketones can help.
The team at Ketogenic Diet Reviews have also completed detailed reviews for the following exogenous ketones:
