New research overturns guideline advice that daily oral iron supplements be taken in divided doses to maximise absorption.
A study of iron-depleted young women in Switzerland has shown that optimum levels of iron are achieved when supplements are taken on alternate days in a single dose.
Taking iron on alternate days may also improve compliance by minimising gastrointestinal side effects, researchers have reported in Lancet Haematology.
In the study involving 40 young women with depleted iron stores, they found that the amounts of iron absorbed from supplements were significantly higher in people assigned to take 60mg on alternate days for 28 days than in those who took the same dose daily for 14 days.
While it’s good to eat fewer carbs overall to control blood sugar levels, it’s not always that easy.
New research has shown that when people eat carbohydrates at the end of the meal after consuming vegetables and protein, their post-meal blood glucose levels were about half as high as when they ate carbs first. The carbohydrate-last meal was also associated with lower insulin secretion and higher levels of a gut hormone that helps regulate glucose and satiety – meaning you’re likely to eat less overall!
