## Abstract

Disclosed herein are compositions comprising tea derived components which are useful in reducing the incidence of cold and/or flu in a subject. Specifically exemplified herein are compositions comprising predetermined amounts of L-theanine and EGCG, and methods of using same.

## Claims

### Claim 1

A method of reducing symptoms of common cold and/or flu in a subject in need thereof, comprising orally administering a therapeutically amount of an admixture of about 25-300 mg of an L-theanine containing composition, wherein the L-theanine containing composition contains at least 95% L-theanine, and wherein the at least 95% L-theanine is standardized at 99%; and about 50-400 mg of a decaffeinated tea polyphenol composition containing at least 45% epigallocatechin gallate (EGCG), wherein the EGCG is standardized at 50%, wherein said admixture reduces the incidence and/or severity of the symptoms of the common cold and/or flu.

### Claim 2 (depends on 1)

The method of claim 1, wherein the admixture is administered in a dosage, wherein the amount of the L-theanine administered is at least 100 mg per day.

### Claim 3 (depends on 1)

The method of claim 1, wherein the admixture is administered in a dosage, wherein the amount of the L-theanine administered is at least 150 mg per day and the amount of the EGCG administered is at least 125 mg per day.

### Claim 4 (depends on 1)

The method of claim 1, wherein said admixture is disposed in a capsule.

### Claim 5 (depends on 4)

The method of claim 4, wherein said admixture is administered as two of said capsules per day.
