Bioavailability - $5000
The beginning study in this grant is to see what effect t aloe has on the human absorption of vitamins C and E, popular vitamin supplements. The study was performed by Dr. Joe Vinson with the Scranton University.
This study took single strength aloe vera gel (liquid) and whole leaf (liquid). The subjects took both vitamins C and E. Subjects took vitamins C and E with aloe and the others took vitamin C and E with water.
All subjects were carefully screened health wise, which included one-half men and one-half women. Age parameters were observed with limitations.
All subjects consumed fat free bagels at the proper time. Plasma and urine samples were taken to the test the bioavailability of both C and E. The tests reflected whether the vitamins were utilized showing up in the plasma and passed through with the urine.
The tests were remarkable in both types of aloe, about 3 times more beneficial when aloe is used to take the vitamins in place of water.
One vitamin was a little better with one type of aloe, but both were approximately 3 times more beneficial with aloe over only water.
Both the gel and the whole leaf aloe improved the absorption of vitamin e and prolonged its plasma concentration, especially after 8 hours.
For vitamin c, the aloe gel was especially effective in slowing down and increasing the absorption of ascorbate. It prolonged its plasma concentration, even for 24 hours.
This study proved that it is necessary to continue these tests using additional subjects for a more defined outcome.
The aloe institute has promised the international aloe science council to cover over 50% of the cost of another expanded study on aloe and vitamin C and E. This study will be conducted in 2005-2006 and results will be included on this website.
