Blood Type Formulas

Your blood type is more than a letter: it’s your body’s unique operating system.

It influences how you digest food, respond to stress, utilize nutrients, and maintain balance. This biochemical individuality is encoded in your DNA and expressed in every system of your body.

At 4YourType, we honor that singularity. Dr. Peter D’Adamo’s pioneering research revealed that the most effective nutrition is not one-size-fits-all: it’s blood type specific. That’s why we create targeted formulas precisely matched to your blood type and health goals. From foundational support to specialized wellness formulas, each product is designed to work with your natural biochemistry, helping you feel stronger, more balanced, and more vibrant.

Discover the power of personalization. Unlock the right formula for your type.
