Vitamin E, death, Alzheimer’s.

In Nov 2004, researchers from Johns Hopkins University warned that high levels of vitamin E led to increased risk of death. The figures were 400 IU (International Units) per day, compared to the limtis recommended at the time – 800 IU in the UK, 1,500 in the US. The findings related to the elderly – those aged 60 plus.

Research just published by the Karolinska Institutet has found that high levels of vitamin E in the blood of the elderly cuts the risk of Alzheimer’s and cognitive deterioration.

To make sense of this, you need to know that vitamin E comes in 8 forms. There are 4 tocopherol forms (alpha, beta, gamma, delta) and 4 tocotrienol forms (again alpha, beta, gamma and delta). Vitamin E supplement is usually alpha-tocopherol, and the Johns Hopkins research was, effectively, on this one form.

The Karolinska Institutet research looked at all 8 forms. The common alpha-tocopherol did not provide a significant risk reduction for Alzheimer’s. On its own, only beta-tocopherol was linked to a reduced risk of Alzheimer’s.

However, a mix of the 4 tocopherols cut the risk by 45%, a mix of the 4 tocotrienols cut it by 54%, and a mix of all 8 components cut the risk by 45%. It’s the mix that counts, not the use of just one of the 8 forms.

Dr. Francesca Mangialasche led the Karolinska Institutet study.
