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.
