Us vs. Them

Them Icon

The Old Way: A Complicated Routine

Gut Health
A resilient, spore-forming probiotic (Bacillus subtilis natto).
A standard probiotic. Efficacy can be a gamble.
Probiotic Efficacy
High-resilience formula allows the bacteria to travel through the stomach acid intact
Often ineffective. Many standard probiotics die in stomach acid and never reach your gut.
Heart Support
Contains Nattokinase, a unique enzyme known for its powerful role in supporting heart health
Requires a separate supplement like CoQ10.
Bone Support
Rich natural source of Vitamin K2, essential for maintaining bone strength.
Requires a separate Vitamin K2 supplement.
Ingredient Purity
100% pure, freeze-dried Natto. No artificial fillers, binders, or unnecessary additives.
Varies by brand. Often contains fillers, binders, and artificial ingredients.
Monthly Cost
Starts at £48. Better ingredients and a more complete formula for less money.
Usually £55+ (for a probiotic, K2, and heart supplement of decent quality).

Freeze-drying

Freeze-drying

This process removes natto’s moisture by applying ultra-low temperatures and vacuum. It preserves the soy nutrients and induces the formation of spore bacteria.

Grinding and capsule preparation
