Isomer enriched conjugated linoleic acid compositions
Compositions and methods of using conjugated linoleic acid preparations enriched for the t10,c12 and c9,t11 isomers are disclosed. It is found that preparations of conjugated linoleic acid containing a ratio of t10,c12 to c9,t11 of about greater than 1.2:1 are desirable for a wide variety of nutritional, therapeutic and pharmacologic uses.
1. A method of elevating white blood cell count in a mammal comprising:
a) providing a CLA composition comprising t10,c12 octadecadienoic acid and c9,t11 octadecadienoic acid in a ratio of about 1.2:1 to 3:1 and a mammal; and
b) administering said CLA composition to said mammal under conditions such that CD4 and CD8 counts are elevated.
2. The method of claim 1 , wherein said CLA composition is administered orally.
3. The method of claim 1 , wherein said CLA composition comprises free fatty acids of t10,c12 octadecadienoic acid and c9,t11 octadecadienoic acid.
4. The method of claim 1 , wherein said CLA composition comprises esters of t10,c12 octadecadienoic acid and c9,t11 octadecadienoic acid.
5. The method of claim 1 , wherein said CLA composition comprises acylglycerides of t10,c12 octadecadienoic acid and c9,t11 octadecadienoic acid.
6. A method of attenuating allergic rections in a mammal comprising:
a) providing a CLA composition comprising t10,c12 octadecadienoic acid and c9,t11 octadecadienoic acid in a ratio of about 1.2:1 to 3:1 and a mammal; and
b) administering said CLA composition to said mammal under conditions such that said allergic reactions are attenuated.
7. The method of claim 6 , wherein said CLA composition is administered orally.
8. The method of claim 6 , wherein said CLA composition comprises free fatty acids of t10,c12 octadecadienoic acid and c9,t11 octadecadienoic acid.
9. The method of claim 6 wherein said CLA composition comprises esters of t10,c12 octadecadienoic acid and c9,t11 octadecadienoic acid.
10. The method of claim 6 , wherein said CLA composition comprises acylglycerides of t10,c12 octadecadienoic acid and c9,t11 octadecadienoic acid.
