Finnish Vitamin D Trial (FIND) conducted at the University of Eastern Finland in 2012–2018. In the FIND trial, 2,495 participants (men 60 years or older and women 65 years or older) were randomised for five years to either the placebo group or the groups that received either 40 or 80 micrograms (1600 or 3200 IU) of vitamin D3 per day. All participants were free of cardiovascular disease and cancer at the start of the trial and were allowed to use their own vitamin D supplement of up to 20 micrograms (800 IU) per day (the recommended intake for this age group at the time when the trial was started). At the beginning and during the trial, research forms were used to collect comprehensive information from the subjects on lifestyle, nutrition, risk factors for and the incidence of diseases. Information on the incidence of diseases and on deaths was also obtained from national health registers.

Approximately one fifth of the randomly selected subjects underwent more detailed examinations and provided blood samples.
