Mineral Interactions and Absorption fact sheet

How minerals are absorbed in the human body

Category: ScienceHealth

Author: Dr. Steven E. Whiting, PhD

Description: Discussing factors that affect mineral uptake and absorption in the human body, and outlines our direct relationship to the mineral depleted soils we grow our crops in, and the general degradation in human health since the pharmaceutical age began.


Factors That Affect Mineral Uptake & Absorption

Tissue samples from animals and humans have shown anywhere from 65 to 75 individual elements, so the first point of concern should be locating a product that provides the full spectrum of minerals. When further evaluating a mineral supplement for human use several factors come to the surface as being relevant. Such factors as pH, electromagnetic circuitry, particle size and source contribute to the final ability for the body to derive benefit from the minerals ingested. The following chart breaks the three basic types of mineral supplements down and shows how they rate in each category along with the subsequent absorption percentage. (Figure 1.0)

Minerals essentially come from one of two sources, either inorganic, being from rocks, clays, seabeds etc., or organic which means that the minerals have been processed through a plant metabolism. This process alters the mineral in some subtle yet vitally important ways namely with regard to the electrical circuitry. For this reason minerals that come from plant sources that contain the full spectrum of minerals would be the best source. After all, humans like all other animals, were created to eat plants, not soil!

Particle Size

There is a law in physical chemistry that states, the smaller the object or particle the greater the surface. This is easier understood if you picture a basketball in your mind and imagine the amount of surface around the outside. Now imagine if that basketball were filled with small marbles. If you measured all the surface around each marble it would be many times greater than that around the big basketball.

The amount of surface of a mineral particle is important since the body attacks and breaks down minerals by attaching to their surface. The greater the surface the greater the absorption, hence the smaller the particle the greater the potential for absorption. Colloids are very small particles that suspend in liquids such as water. These particles contribute to overall absorption due to the immense surface the body has available to acidify and break them down.


pH stands for power of hydrogen and refers to how acidic or alkaline a substance is. The pH scale runs from 0 through 14. The mid point, number 7 is neutral. Everything lower than 7 is acidic and everything higher than 7 is alkaline.

In order for minerals to be properly absorbed, they need to be acidic. When we consume inorganic minerals which are always quite alkaline, the body must attempt to acidify them for absorption. This is done in several ways but early acidification of minerals occurs through hydrochloric acid from the stomach.

This accounts for why we have greater difficulty absorbing minerals as we grow older. The natural hydrochloric acid production decreases with age and dietary abuse. Organic colloidal minerals are naturally acidic, about 3.0 to 5.5, and this further contributes to their absorption.
