I switched to a vegetarian diet a while back, and I am now taking a few supplements consisting of common minerals, vitamins and omega-3's as a compliment to my regular diet.
When should I take the supplements to ensure that they are absorbed most effectively?
Does it matter what time of day it is, and does it matter what else I have in my stomach at the time?
I have read that some vitamins are fat soluble – does that mean that they should be taken with a meal? If taken with a meal – does eating a lot of food reduce "digestion efficiency" of the supplements?
What I have done, which is based entirely on my own thoughts, which are not based on any particular research:
I have been taking my supplements during the afternoon a few hours before dinner. At around 5 pm, body metabolism is at a high, and I usually don't have a lot of food in my stomach. My thinking has therefore been that the body will be efficient at absorbing the contents of the supplements.
I have avoided taking supplements in the morning because I am a morning coffee-drinker, and caffeine is laxative.
