Phytocal Multimineral

A Superior Form of Calcium

Designed by Dr. Peter D’Adamo, these products feature a unique natural source of calcium: The small red seaweed called "Maerl" found only in the isolated areas off the pristine coast of Northwest Ireland. Of all sources of calcium, Maerl has one of the lowest levels of undesirable contaminants. Using Maerl calcium as a base, Dr. D’Adamo has crafted four different mineral formulas using unique cofactors and micromineral ratios specific for each blood type. Maerl calcium has one of the lowest levels of lead found in any natural calcium source.

The pristine shores of the Irish Coast.

All Phytocal® mineral formulas feature Maerl-based sea calcium, the only natural source of calcium with a broad enough buffering range to work effectively amid the differing digestive capabilities of each blood type. Maerl is composed of a wide variety of essential nutrients including calcium, magnesium, boron and zinc. Maerl’s unique structure gives it great versatility, and when woven into formulas tailored to the genetics of ABO blood type, insures a phenomenal rate of bioavailability and utilization. Its superior buffering capacity allows Phytocal Maerl-based calcium to maintain very high rates of absorption despite the variable acid and alkaline levels found in the digestive tracts of the four ABO groups. Phytocal calcium is of highly consistent particle size with excellent dispersion qualities. The solubility of Phytocal calcium can be appreciated visually: There is virtually no sedimentation after dispersion.

Why Blood Type Matters

Research as far back as the early 1960s clearly demonstrated that mineral absorption varies between the different blood types. In large part, this is due to major differences between the blood types with regard to an intestinal enzyme known as 'intestinal alkaline phosphatase' (IAP). This enzyme plays an important role in early life, helping to condition the digestive tract of the developing fetus. In later life, IAP plays an crucial role in absorption of calcium from the diet. Studies have shown that IAP varies by as much as 2.5 fold (250%) between the blood types, from a high level in type O secretors, to a low level in type A non-secretors. Consequently, adjusting a mineral formula to take the blood type differences into account has been a priority for Dr. Peter D'Adamo.

Because each blood type possesses variable assimilation capabilities and requires differing cofactor and trace mineral requirements, Dr. D'Adamo designed four different formulas:

Phytocal A: features higher levels of the important antioxidant selenium; the gastric activating cofactors betaine hydrochloride, renett and gentian root (Gentiana lutea) plus the mineral-rich herb horsetail (Equisetum arvense). Phytocal A also features significant levels of the important calcium absorption enhancer, ipriflavone, and a small dose of vitamin A to enhance the activity of the calcium absorbing enzyme intestinal alkaline phosphatase.

Phytocal AB: features higher levels of the important co-minerals magnesium, manganese and molybdenum; the stomach-acidifying cofactors betaine hydrochloride and renett. Phytocal AB also features yellow dock (Rumex crispus) as a gentle source of iron.

Phytocal B: features the highest levels of magnesium -an important nutrient for nerve and muscle function; chromium to help balance carbohydrate function and proper doses of iron and copper -two important blood-building nutrients. Phytocal B also features higher levels of vitamin D and vitamin K -important calcium absorption cofactors.

Phytocal O: features balanced levels of the micro and macro-minerals magnesium, iron, copper and zinc; manganese to help insure proper joint and ligament function and micro-trace amounts of iodine to enhance thyroid function. Phytocal O also features nettle leaf (Urtica dioica) an important aid to proper intestinal assimilation.

When considering whether to supplement with a multimineral, remember: There are significant differences in calcium absorption and availability. A clean, natural, calcium source with the best bioavailability, designed for your unique absorption capabilities. We think you'll choose Phytocal.
