• 
  COLLAGEN PROTEIN: Get the protein your body needs with the help of our keto bars. Each one delivers over 10g grass fed collagen per serving - helping to support hair, skin, nail, joint and muscle health.
• 
  MCT OIL: What sets apart our protein bars from others is that we've included MCTs (medium chain triglycerides). MCT's are a unique type of fatty acid found in coconut oil that are a much faster source of energy than most longer chain fatty acids. They support focus and sharpness, help you feel fuller for longer, and allow for better bioavailability.
• 
  LOW CARB SNACK, ANYTIME, ANYWHERE: Sometimes there's not enough time to prepare a meal and most "on-the-go" low carb snacks provide poor nutrition. We spent a year developing the formula for a great-tasting, keto-friendly bar with quality ingredients formulated to keep you in ketosis. The bars are portable and convenient and great for travel, work, or before the gym.
• 
  CLEAN PROTEIN BARS: Perfect Keto's Collagen Protein Bars are made with no added sugars, sugar alcohols, additives, or fillers. They're packed full of quality ingredients that provide sustained energy to fuel your mind and body. Whats inside? Almonds, cacao butter, coconut oil, and collagen, with a touch of sea salt and stevia.
