These 8 Supplements May Be the Secret to Success on the Keto Diet

Let's be honest, sticking to a keto diet can be difficult; we all give in to happy hour apps and cocktails sometimes. Perfect Keto's Exogenous Ketone Base ($59, originally $79) can help you more easily get into ketosis and stay there. Start your day (or any time you need a little extra pep) with this sugar-free, dessert-flavored boost of ketones for improved energy and focus. We suggest mixing with coffee for a chocolaty morning treat.

MCT stands for medium-chain triglycerides, a type of fatty acid that the body can easily use for fuel, instead of being stored as fat. This unique quality makes Keto and Company's MCT Oil ($20 and up) perfect for the keto diet. MCT oil can be added to your morning coffee, but it is also great for baking, in smoothies, and in salad dressings.

Sugar is a big no-no on the keto diet, but it just happens to be one of the big players in most sports drinks. Not so for Perfect Keto's Ketone Sports Drink ($54, originally $69)! It provides ketones, MCT oil, and caffeine (from green tea) for energy and BCAAs and creatine to power your muscles during your workout.

This keto-friendly shake is basically a meal in a glass. The Keto Feast ($70) macronutrient breakdown is tailored to the keto diet (higher in fat, lower in carbs), and it also provides MCT, a hit of caffeine, and a whole host of nutrients that most of us simply don't get enough of (like collagen, probiotics, and omega-3s).

Perfect Keto's collagen protein powder ($39, originally $59) is just the keto-friendly protein powder you've been looking for. The addition of MCT to the collagen actually helps to slow the absorption of the protein to power your workout and recovery. Even better, it's made with no refined sugars and absolutely nothing artificial.

All digestive enzymes help your body to break down and absorb the food you eat, but that doesn't mean they are all the same. Keto Digest's ($60) one-of-a-kind blend of digestive enzymes is specifically designed to work with a high-fat, low-carb diet like the keto diet. Bonus: you'll get a gut-health boosting dose of probiotics, too!

KetoPrime ($60) touts itself as "High Performance Brain Food," and we can see why. Made from a concentrated source of oxaloacetate (just call it OAA), KetoPrime can help you beat brain fog and boost your energy, common side effects when starting a keto diet.

It's no secret at this point that good gut bugs are necessary for good health, and Ancient Nutrition's Keto Biome ($60) is the high-quality, keto-friendly probiotic supplement that your belly has been looking for. Keto Biome contains soil-based probiotics and organic fermented herbs that help to support digestion and immune health — something we all need whether following a keto diet or not.
