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 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 — more than almost any known food

Most spermidine supplements offer just 1–6 mg per capsule — you can get that from just a spoonful of Rhiza.

Spermidine: Activate Your Inner Autophagy

Ergothioneine: The “Longevity Vitamin”

Ergothioneine is a rare antioxidant amino acid found in mushrooms and a few other fungi. 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 — putting it on par with gourmet mushrooms like king trumpet and shiitake.

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

Ergosterol: The Vitamin D2 Precursor

Ergosterol is the fungal equivalent of cholesterol — but instead of harming health, it helps support it. When exposed to UV light (or digested in the body), ergosterol can convert into vitamin D2, which is essential for:

  • Immune function

  • Bone health

  • Hormone regulation

Rhiza contains 6.94 mg/g of ergosterol, far exceeding the levels found in common edible mushrooms.

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

  • Ergosterol to support immunity and vitamin D levels

Together, they form a powerful trifecta 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.
