## Abstract

A food supplement comprising a mineral complex obtained from coral by soaking it in a solution of organic acid suitable for ingestion such as citric acid or acetic acid and by extracting minerals from the coral by the action of said organic acid.

## Claims

### Claim 1

A food supplement comprising a mineral complex which comprises minerals extracted from coral, wherein said coral is not a ground material, by soaking the coral in an organic acid solution which is suitable for ingestion to form a resultant soaking solution comprising a supernatant and a precipitate; and separating at least one component, selected from the group consisting of supernatant and precipitate, from the other components of the soaking solution, and wherein said at least one component is employed as a food supplement.

### Claim 2 (depends on 1)

The food supplement of claim 1 wherein said organic acid is either citric acid or acetic acid.

### Claim 3 (depends on 1)

The food supplement of claim 1 wherein said mineral complex is the supernatant of the soaking solution containing minerals extracted from said coral, or an evaporate thereof.

### Claim 4 (depends on 1)

The food supplement of claim 1 wherein said mineral complex is the precipitate separated from the soaking solution which contains minerals extracted from said coral.

### Claim 5

A method of producing a food supplement comprising the steps of:
soaking coral in a solution of an organic acid suitable for ingestion to form a resultant soaking solution comprising a supernatant and a precipitate: and
separating at least one component, selected from the group consisting of supernatant and precipitate, from the other components of the soaking solution;
wherein said coral is not a ground material.

### Claim 6 (depends on 5)

The method of claim 5 wherein said organic acid is either citric acid or acetic acid.

### Claim 7 (depends on 5)

The method of claim 5 comprising separating the supernatant from the soaking solution containing minerals extracted from said coral.

### Claim 8 (depends on 7)

The method of claim 7 further comprising evaporating water from said supernatant.

### Claim 9 (depends on 5)

The method of claim 5 comprising separating the precipitate from the soaking solution containing minerals extracted from said coral.
