A Rutgers University study found that overweight and obese older women who took more than three times the recommended daily dose of vitamin D showed improvements in memory and learning. BUT it also slowed their reaction times (when taking 2,000 IU ore more a day) which could increase falling, i.e fractures, and broken bones among older people. Researchers did not understand the cause.
The researchers evaluated three groups of women between 50 and 70 years of age in a randomized controlled trial.
Group A: Took the recommended daily dose of 600 International units (IU), which is equivalent to 15 micrograms of vitamin D each day for a year.
Group B took 2,000 IU per day.
Group C took 4,000 IU per day.
All women participated in lifestyle counseling and were encouraged to lose a modest amount of weight.
The researches found that memory and learning improved in Group B (who took 2,000 IU per day. Group C did not improve with the higher dosage.
Vitamin D is known for its importance for bone health-is obtained through sun exposure and some foods. Researches have also found that vitamin D has a major impact on how the body functions, including the brain.
May your days be filled with good health, good friends, good food, and most of all; much love,
