Grass fed butter has found a new use in America: being added to coffee. This trend, started by Dave Asprey of Bulletproof and his company Bulletproof Labs, aims to boost energy levels while aiding weight loss. The drink combines black coffee with unsalted grass-fed butter and MCT oil, also known as coconut oil; both add healthy fats useful for ketogenic diets – it has quickly become a favorite drink among those adhering to the Bulletproof Diet.

Your morning coffee should include butter and MCT oil as a healthy way of increasing the healthy fats you are taking in and giving you long-term energy boost. For maximum benefits, choose high quality grass-fed butter and coconut oil varieties.

What makes grass-fed butter unique from regular varieties is the cows are allowed to consume their natural diet of grass rather than grain, resulting in key nutritional differences between them. According to past research, grass-fed butter contained higher Omega-3 fatty acid content and less saturated fat compared with traditional butter varieties. Furthermore, grass-fed butter may contain higher concentrations of K2, an anticalcification vitamin produced in cow stomachs when digesting grass that can help counteract arterial plaque build-up.

At home, if you want to recreate this drink it’s best to use a blender in order to ensure all of the fats emulsify and create a creamy texture. Combine a cup (8-12 ounces) of brewed coffee with 1-2 tablespoons of grass-fed unsalted butter and 1-2 teaspoons of MCT oil (or another healthy fat such as coconut oil).

These ingredients combine to produce a drink that tastes and feels just like a latte, with customizing options to your preferences such as natural sweeteners or zero-cal/low-carb alternatives to sugar. Some people also include collagen powder for skin, muscle and joint health as well as chaga mushroom powder to support immunity and gut wellbeing.

To get the best out of this combination, it is recommended that you use high-quality coffee and a blender to mix all of the ingredients thoroughly and emulsify and incorporate fats into the drink, which will make the experience more pleasurable while increasing digestibility.

The Bulletproof recipe requires one cup of coffee, one to two tablespoons of MCT oil and 1-2 tablespoons of unsalted grass-fed butter as an energy and focus booster. Butter from grass-fed cows provides medium-chain triglycerides which have long been recognized for providing energy and satisfying hunger pangs; adding MCT oil will up these benefits even further as another excellent source of easily assimilated fats, leaving many feeling energized and focused after drinking it – though some people may struggle to tolerate its fats which could cause gas or bloat in these instances.
