Phytocal B, developed by Dr. Peter D'Adamo, is a personalized multimineral supplement with highly bioavailable seaweed calcium to support healthy bones and improve calcium digestion and assimilation in Blood Type Bs.

The unique ingredient in Phytocal B is maerl-based sea calcium, the only natural source of calcium with a broad enough buffering range to work effectively with the different digestive capabilities of each blood type. It comes from the rare maerl seaweed, found only in isolated areas off the coast of southwest Ireland.

Personalized multimineral Phytocal B supports overall health in a multitude of ways:

  • Provides support for healthy bones and calcium absorption in Blood Type Bs
  • Supports healthy joint and ligament function
  • Supplies trace amounts of essential nutrients such as magnesium, boron and zinc to support bone strength and immunity
