Start your day with a coffee that does more. The Maximizer™ is a medium-dark roast made with high-quality, clean beans and enhanced with functional ingredients. Each pod contains prebiotics, slippery elm bark and chromium picolinate—selected to support gut balance and metabolic function.
Prebiotics nourish the gut’s natural bacteria, while slippery elm bark helps soothe the digestive tract. Chromium picolinate is included to support normal blood glucose levels.
The blend is smooth, rich, and carefully roasted to preserve flavour without compromise. Whether it’s your first cup or a midday pick-me-up, The Maximizer™ is an easy way to support your wellbeing—starting with what’s in your mug.
Bulletproof products use only high-quality, clean ingredients—free from GMOs, soy, gluten, and artificial fillers. Maintaining rigorous sourcing standards, the brand’s coffee beans are sourced from Rainforest Alliance Certified farms and undergo strict testing to eliminate mould toxins, ensuring you get pure, clean coffee in every cup.
The brand was founded by Dave Asprey, a well-known biohacker, author and entrepreneur who has worked hard to improve human health and performance. With a background in computer science and a strong interest in neuroscience and nutrition, Asprey set out to improve his own biology, which led to the development of the Bulletproof brand. With innovative supplements and nutritional products designed to help you perform better, think faster, and live better, Bulletproof is the go-to for anyone looking to unlock their full potential.
