Rhiza mycoprotein: naturally rich in longevity nutrients

At the Better Meat Co., we don't just make delicious food — we grow functional fungi with benefits that go beyond protein. Our Rhiza mycoprotein is a fermented whole food rich in compounds linked to healthy aging, immunity, and cellular protection.

Here’s what sets Rhiza apart from other foods:

Spermidine: Activate Your Inner Autophagy

Spermidine is a naturally occurring compound that supports cellular renewal by activating autophagy—the body's process of clearing out damaged cells and regenerating healthier ones. It’s been linked to:

  • Improved cardiovascular health

  • Longevity in animal models

  • Neuroprotective effects

Rhiza contains 20.3 mg of spermidine per 100g dry weight — ranking it a top spermidine-containing food.

Ergothioneine is a rare antioxidant amino acid found in mushrooms.. It's been nicknamed the "longevity vitamin" by scientists due to its ability to:

  • Scavenge free radicals

  • Protect mitochondria

  • Support brain and immune health

Rhiza delivers 0.604 mg/g of ergothioneine — more than most mushrooms.

Unlike isolated ergothioneine powders, Rhiza offers this nutrient in a whole-food matrix, along with fiber, protein, and additional functional compounds.

Ergothioneine: The “Longevity Vitamin”

Nature’s Longevity Stack — In a Single Ingredient

What makes Rhiza mycoprotein special isn’t just one nutrient — it’s the synergy:

  • Spermidine to stimulate cell renewal

  • Ergothioneine to protect mitochondria and DNA

Together, they form a powerful duo found in few other foods — let alone in one clean-label, allergen-free, neutral-tasting ingredient.

Longevity starts with what you feed your cells. With Rhiza, you’re not just eating smarter — you’re aging better.
