Grass-fed New Zealand whey protein isolate infused with wild-sourced Chaga, Reishi, and Cordyceps mushroom extracts — a post-workout protein that goes beyond muscle recovery to support gut health, immune resilience, focus, and sleep. Clean ingredients, digestive enzymes for better absorption, no artificial additives. Australian made, Byron Bay born.
Most protein powders do one thing: deliver protein to support muscle repair after training. Bytropic WPI does that — and then layers three functional mushrooms on top that address what the typical protein powder ignores: the gut environment that absorbs your nutrients, the immune load that training places on your body, the cognitive demands of a full day after a hard session, and the nervous system recovery that determines how well you actually sleep and rebuild.
The protein base is whey protein isolate sourced from grass-fed, pasture-raised New Zealand cattle — one of the cleanest WPI sources available, with a high leucine content and a complete essential amino acid profile. Digestive enzymes are added specifically to improve how well the protein is broken down and absorbed — addressing the common complaint of bloating or digestive discomfort that many people experience with whey protein.
The three mushroom extracts are wild-sourced and chosen for their complementary roles: Chaga for antioxidant and gut health support, Reishi for post-workout recovery and nervous system balance, Cordyceps for energy production and oxygen efficiency. Together they turn a routine post-workout shake into something that supports your whole system — not just your muscle fibres.
The mushroom selection is deliberate and each extract serves a specific purpose within the context of training and recovery.
Chaga is one of the highest antioxidant-density mushrooms studied. Training generates oxidative stress — reactive compounds that, if left unchecked, contribute to inflammation, delayed recovery, and gut wall stress. Chaga's antioxidant compounds help neutralise this load, while also supporting the gut microbiome directly.
Reishi's role here is specifically post-workout: it is an adaptogen that helps bring the central nervous system back toward balance after the stress of exercise. Chronic training without adequate nervous system recovery is one of the most common causes of poor sleep, elevated resting heart rate, and plateaued performance. Reishi supports the downregulation that allows genuine overnight recovery to happen.
Cordyceps supports ATP production and oxygen uptake efficiency — the same mechanisms studied in athletic performance research. In the context of a post-workout shake it contributes to faster energy system replenishment, and taken consistently it supports endurance and stamina over time.
Digestive enzymes are the practical inclusion that makes everything else more effective — they ensure the protein you're taking is actually broken down and absorbed rather than causing digestive strain.

Note: Contains milk (whey). Not suitable for those with dairy allergies.
Mix 1 scoop with 200–300ml of water, milk, or your preferred liquid and shake well. Best taken within 30–60 minutes post-training to support muscle protein synthesis and recovery. Can also be used as a high-protein meal supplement at any time of day.
For best results, use daily as part of a consistent training and recovery routine. The mushroom extracts build their benefits over time with regular use — not just in single doses. Pair with adequate sleep and whole food nutrition for optimal results.
