Following a ketogenic diet can significantly impact how you feel and perform. This high-fat, low-carb eating plan can sometimes lead to nutrient deficiencies or other challenges, and supplements can help bridge those gaps. Here are the top 9 supplements for a keto diet you should consider to optimize your health and well-being.
Magnesium
Magnesium is a crucial mineral that plays a role in over 300 enzymatic reactions in the body, including energy production, muscle function, and nerve signaling.
On a keto diet, magnesium-rich foods like beans and fruits are typically off-limits due to their high carb content. As a result, many people on keto may find themselves deficient in this essential nutrient. According to a study, "Research suggests that due to magnesium-depleting medications, reliance on processed foods, and other factors, a good portion of the population has or is at risk of developing a magnesium deficiency" (Healthline, 2021).
Magnesium deficiency can lead to symptoms such as muscle cramps, fatigue, and difficulty sleeping. To counteract this, consider taking 200-400 mg of magnesium per day. Some of the most absorbable forms include magnesium glycinate, magnesium gluconate, and magnesium citrate. Additionally, incorporating keto-friendly, magnesium-rich foods like spinach, avocado, and pumpkin seeds into your diet can help.
MCT Oil
Medium-chain triglycerides (MCTs) are a type of fat that is quickly absorbed and converted into ketones, making them a staple for many keto dieters. MCT oil, derived from coconut or palm oil, provides a concentrated dose of these beneficial fats.
One advantage of MCT oil is its ability to boost ketone levels, helping you stay in ketosis more easily. MCT oil can also promote weight loss and increase feelings of fullness, making it easier to adhere to your keto diet. You can add MCT oil to your morning coffee, smoothies, or simply take it by the spoonful. Start with a small dose to see how your body reacts, as some people may experience digestive issues like diarrhea or nausea.
Omega-3 Fatty Acids
Omega-3 fatty acids, found in fish oil or krill oil supplements, are essential for reducing inflammation, supporting heart health, and preventing mental decline.
Western diets are often high in omega-6 fatty acids and low in omega-3s, leading to an imbalance that can promote inflammation. Supplementing with omega-3s can help restore this balance, especially on a high-fat diet like keto. In fact, "one study showed that people following a ketogenic diet who supplemented with omega-3 fatty acids from krill oil experienced greater decreases in triglycerides, insulin, and inflammatory markers than those who did not" (Healthline, 2021).
Omega-3 supplements can also enhance the overall health benefits of the ketogenic diet. Aim for a supplement that provides at least 500 mg of combined EPA and DHA per serving.
Vitamin D
Vitamin D is vital for bone health, immune function, and inflammation regulation. Although the keto diet doesn't inherently increase the risk of vitamin D deficiency, it's a common issue for many people.
Since few foods naturally contain vitamin D, supplementation is often necessary to ensure adequate intake. Maintaining optimal vitamin D levels improves calcium absorption, crucial for bone health, especially for those who are lactose intolerant and may not get enough calcium from their diet. Your doctor can perform a blood test to determine your vitamin D levels and recommend an appropriate dosage based on your needs.
Digestive Enzymes
Transitioning to a high-fat keto diet can be tough on your digestive system, leading to symptoms like nausea, diarrhea, and bloating. Digestive enzyme supplements can help ease these symptoms by breaking down fats and proteins more efficiently. Look for a blend that contains lipases (for fat digestion) and proteases (for protein digestion).
Digestive enzymes also have the added benefit of reducing post-workout soreness, which can be a bonus for those who exercise regularly on a keto diet.

Exogenous Ketones
Exogenous ketones are ketones that come from an external source, as opposed to those produced naturally by your body. These supplements can help increase blood ketone levels, potentially helping you reach ketosis faster. They are often used by athletes to boost performance, speed up muscle recovery, and decrease appetite.
While promising, research on exogenous ketones is still limited, and their necessity for keto dieters is debated among experts. Most studies use ketone esters, a more potent form, rather than the more common ketone salts found in consumer supplements. While some may find these supplements helpful, more research is needed to fully understand their benefits and risks.
Greens Powders
Incorporating enough vegetables into a keto diet can be challenging due to carb restrictions. Greens powders offer a convenient way to boost your intake of essential vitamins, minerals, and antioxidants. These powders typically contain a mix of powdered vegetables like spinach, kale, and broccoli, along with other nutrient-dense plants like spirulina and chlorella.
Greens powders can help fill nutritional gaps and support overall health.
Add them to your smoothies, shakes, or simply mix with water for a quick nutrient boost. However, they should not replace whole vegetables in your diet but rather complement them.
Electrolytes
Electrolyte imbalances are common when starting a keto diet, as the body loses more water and essential minerals like sodium, potassium, and magnesium. This can lead to symptoms of the "keto flu," such as headaches, muscle cramps, and fatigue. Supplementing with electrolytes can help alleviate these symptoms and support overall well-being.
Electrolyte supplements are especially beneficial for hydration and muscle function, particularly for athletes. You can find electrolyte supplements in various forms, including powders, tablets, and drinks.

Performance-Enhancing Supplements
Athletes following a keto diet may benefit from specific supplements that enhance performance and recovery. Creatine monohydrate is one such supplement, known for promoting muscle gain, improving exercise performance, and increasing strength.
Another option is beta-alanine, which can help prevent fatigue and muscle burnout during intense workouts.
Branched-chain amino acids (BCAAs) are also popular among athletes for reducing muscle soreness and fatigue. Additionally, HMB (beta-hydroxy beta-methylbutyrate) can help decrease muscle loss and increase muscle mass, particularly for those new to exercise or increasing workout intensity. Caffeine, found in coffee or green tea, can also boost energy levels and enhance performance. For more guidance, check out our article on 9 Common Keto Diet Mistakes to Avoid and Correct.
Conclusion
In conclusion, the right supplements can significantly enhance your experience on a keto diet, helping to fill nutritional gaps, support overall health, and improve athletic performance. From essential minerals like magnesium and electrolytes to performance-enhancing supplements like creatine and BCAAs, there are various options to consider based on your individual needs and goals.
Keep in mind that while supplements can be beneficial, they should not replace a well-balanced diet. Focus on consuming nutrient-dense, keto-friendly foods and use supplements to complement your dietary choices.
