🧠 Product & Ingredients

What is Lion’s Brain®?

Lion’s Brain® is a range of premium hand cooked potato crisps made with British potatoes and seasoned with a blend including Lion’s Mane extract and zinc.

What is Lion’s Mane extract?

Lion’s Mane (Hericium erinaceus) is an edible mushroom named after its distinctive, shaggy appearance, which resembles a lion’s mane. An extract is made by processing the mushroom to draw out some of its naturally occurring compounds.

At Lion’s Brain®, we use extract from the mushroom’s fruiting body - the part you would recognise as the mushroom -and blend it into the seasoning across all three flavours.

Our crisps also contain added zinc, which contributes to normal cognitive function. It’s all part of our approach: Taste then function.

Why do you include zinc?

Zinc contributes to normal cognitive function as part of a balanced diet.

Do your crisps taste like mushrooms?

No — each flavour is carefully balanced. The Lion’s Mane extract does not dominate.

Are your crisps “functional”?

We focus on great taste using thoughtfully selected ingredients.
