What it supports
- Memory, early research*
- Focus support*
- Brain health*
Lion’s mane is the culinary mushroom at the heart of today’s focus routines. In a placebo-controlled study, healthy adults were faster on an attention task an hour after a single 1.8 g dose. In another, reaction time was quicker 2 hours after 1 g, the same as our daily serving.* Each serving gives you 1,000 mg of organic lion’s mane, standardized to 40% polysaccharides, in vegan capsules.
