Chemeda Oy says that the university has been slow to respond since two follow-up studies did not replicate the deficiencies found by the original research. It is now set to seek compensation via the courts.
Company CEO Tero Weckroth says that his firm has been notified that the university denies liability and has promised to provide further details by January 15. Weckroth claims that response is unsatisfactory, as the university had previously said it would respond by December 17.
The University of Eastern Finland refused to comment on the matter. It admitted in November that its vitamin D supplement research was flawed. The research had caused supplement makers serious concern when published in October.
