Taken at the right dose, supplements are widely acknowledged by experts to be of benefit across the population. Independent tests carried out on a number of products, however, have raised concerns over the safety of high doses and prolonged use. Vitamin E supplements, for example, may increase the risk of a haemorrhagic stroke and lower the risk of ischaemic strokes, according to one study.
Stroke can be broken down into two different forms.
According to the health body Cedars-Sinai: “A haemorrhagic stroke occurs when blood from an artery suddenly begins bleeding in the brain.”
The health body defines an ischaemic stroke, on the other hand, as a stroke that occurs “when blood supply is cut off to part of the brain”.
According to one study, the risk of the latter could increase in line with prolonged supplementation with vitamin E.

Health experts have continuously warned against the use of vitamin pills as substitutes for a healthy diet, stressing that other compounds found in fruits and vegetables are equally important.
According to the NHS, good sources of vitamin E include plant oils, such as rapeseed, sunflower, soya, corn and olive oil. Nut seeds, and wheat germ, which is found in cereals, are also good sources.
What is vitamin E?
Naturally occurring vitamin E exists in eight different chemical forms, that have varying levels of biological activity.
Tocotrienols, for example, are thought to have more potent antioxidant properties than alpha-tocopherol, According to the medical journal Life Science.
Currently, alpha-tocopherol is the only form of vitamin E recognised to meet human requirements, according to the National Institutes of Health.
