Keto Protein Powder
Our keto protein powder is a plant-based formula, low in salt and with no added sugar, artificial additives or preservatives.
When following any diet, especially a keto, low calorie or plant based diet, it can be difficult to achieve sufficient protein through food alone. Unlike fats and carbohydrates, your body cannot store protein, which is why keeping up a good daily intake is so important to support metabolic health.
The Fast 800 keto protein powders gives you a quick and easy way to boost your protein intake, without impacting your calories. Each serving of our keto protein powder contains over 20g protein and less than 120 calories. The protein powder is made from natural ingredients, comes in two delicious flavours and is free from nuts, gluten, dairy, soy and egg.
