Carotenoid-containing compositions and methods
View Patent ↗The present invention is directed to carotenoid compositions and methods for inhibiting the growth of pathogenic bacteria or for preventing or treating bacterial infections in subjects by administration of an effective amount of astaxanthin and beta-carotene.
1. A method for inhibiting the growth of H. pylori in an infant in which H. pylori is present, comprising administering to the infant a nutritional composition comprising a carbohydrate source, a lipid source, a protein source, beta-carotene in an amount of from about 50 mcg/L to about 1150 mcg/L, astaxanthin in an amount of from about 50 mcg/L to about 1150 mcg/L, polydextrose, galactooligosaccharide, and Lactobacillus rhamnosus GG.
2. The method of claim 1 , wherein the nutritional composition comprises each of astaxanthin and beta-carotene in an amount within the range of from about 75 mcg/L to about 230 mcg/L.
3. The method of claim 2 , wherein the nutritional composition comprises each of astaxanthin and beta-carotene in an amount within the range of from about 100 mcg/L to about 200 mcg/L.
4. The method of claim 1 , wherein the nutritional composition comprises up to about 2000 mcg/L of the carotenoid blend.
5. The method of claim 1 , wherein the nutritional composition comprises galacto-oligosaccharide in an amount in the range of from about 1.0 g/L to about 4.0 g/L.
6. The method of claim 1 , wherein the nutritional composition comprises polydextrose in an amount in the range of from about 1.0 g/L to about 4.0 g/L.
7. The method of claim 1 wherein the nutritional composition is an infant formula.
8. The method of claim 1 , wherein the nutritional composition further comprises, in addition to the lipid source, arachidonic acid and docosahexanoic acid having a weight ratio of from about 1:3 to about 9:1.
