An important note is to take it in the morning, not at the evening. The article misses it somehow. Intervention group received a 50 000-unit vitamin D supplement, one in a fortnight for 8 weeks Not sure what this formula means, but 50,000 IU is way too much for a single dose. 10,000/day is prescribed only to eldery people who have enormous deficiencies on the edge of death, according to my endocrinologist. Check your D levels before eating any supplements. https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-d/ https://www.nhs.uk/conditions/vitamins-and-minerals/vitamin-... Do not take more than 100 micrograms (4,000 IU) of vitamin D a day as it could be harmful. This applies to adults, including pregnant and breastfeeding women and the elderly, and children aged 11 to 17 years.
