Beta-carotene in tube feeding.
The supplementation of an enteral feeding formula on soya-basis specially designed for geriatric patients with 1,5 mg to 2 mg beta-carotene per day increases its corresponding plasmatic concentration from 20 mcg/L to normal to optimal levels near 500 mcg/L. This intake is much lower than the proposed safe intake of 6-20 mg beta-carotene per day. A close incorporation of beta-carotene in the lipid moiety of the ready-to-use formula might increase its bioavailability. The other anti-oxidative vitamins A and E remain to their respective normal levels at a supplemental daily intake of 2500 IU vitamin A and 12,5 mg vitamin E. The new enteral feeding formula for geriatric patients seems to cover their global nutritional needs.
