Sulla vitamina E sono state aperte molte discussioni, posto uno studio datato Luglio 2007:
Vitamin E is one of the most important phytonutrients in edible oils. It consists of eight naturally occurring isomers, a family of four tocopherols (alpha, beta, gamma and delta) and four tocotrienols (alpha, beta, gamma and delta) homologues.
Some sources of tocopherols are Palm Oil (the highest), soy bean oil, rice bran, peanut oil, coconut oil, olive oil.
The invention was awarded for a formulation for promoting hair growth and preventing hair loss using a formula that comprises of mixed tocotrienols and a pharmaceutically acceptable excipient.
The inventors conducted a randomized, double blind, placebo-controlled two groups parallel study to compare the effect of a mixture of tocotrienols, comprising .alpha.-, .gamma.-, and .delta.-tocotrienols and alpha-tocopherol, with placebo on hair growth.
All volunteers were randomized to receive one capsule comprising either (i) a mixture of tocotrienols and alpha-tocopheral, or (ii) a placebo, twice daily after food over a period of at least 5 months. They were seen for an efficacy evaluation every month throughout the study. The control was a placebo capsule containing 600 mg of soya bean oil, and the tocotrienol formulation consisted of capsules containing a mixture of about 50 mg of tocotrienols and about 23 i.u. alpha-tocopherol. The entire study took 15 months for completion.
Results of Hair Growth Studies
Nineteen patients (14 men and 5 women) entered the study and completed at least the first 5 months of therapy. Their ages ranged from 23 to 59 years. The mean duration of current alopecia episode was approximately 5 years. The extent of alopecia was as follows: less than 25%, 6 patients; 25 49%, 8 patients; 50 74%, 4 patients; 75 99%, 1 patient.
Eleven volunteers were randomized to receive the tocotrienol formulation supplementation while 8 volunteers were in the placebo group. Comparability of the treatment groups with respect to initial hair counts as well as the weight of hair was assessed. No statistically significant difference between treatment groups was detected for any of the above characteristics.
At the end of the supplementation period, all volunteers in the tocotrienol formulation group had positive results, recording an increase in the number of hairs in the evaluation area. Seven volunteers (64%) showed regrowth of between 10 35% while 3 volunteers (27%) had 50% or gr
