When is it better to take these tablets: morning or evening, with food or without?

Vitamin D3 is a fat-soluble nutrient, and this determines the main rule for taking it: it is best taken with a meal that contains fats. This can be a breakfast with an egg or avocado, a lunch with fish or meat, or any meal that includes vegetable or animal fats. Taking it on an empty stomach or with a completely fat-free meal reduces the efficiency of absorption.

As for the time of day, there is no firm scientific evidence that taking it in the morning is fundamentally better than in the evening (or vice versa). Still, some people note that taking vitamin D closer to the evening subjectively affects the quality of their sleep. This is individual and not a universal rule, but if you notice such an effect, it is more convenient to move the dose to the first half of the day.

A practical tip: choose the same meal every day and link the tablet to it. Regularity matters more than the exact time: vitamin D accumulates gradually, and missed doses reduce the effect of the course more than a difference of a couple of hours.

• Take it with food that contains fats.
• Taking it in the morning or during the day is the most common practice.
• Choose a convenient time and stick to it every day.
