A clinical epidemiological study involving more than 2,400 participants in Finland investigated the association between blood levels of vitamin C and the occurrence of stroke. The study participants were patients with hypertension – a condition associated with an increased risk of stroke – who were observed over a period of 10.4 years. The results of the trials showed that – regardless of all other factors – male hypertensive patients with low vitamin C levels had a 2.6-fold higher risk of stroke. Further details can be found in the study.
