Millions of French people take vitamin D supplements, but taking them with black coffee on an empty stomach may reduce their effectiveness.
Vitamin D absorption depends on fat
Vitamin D is a fat-soluble vitamin, meaning it is absorbed more effectively when consumed with dietary fats, unlike water-soluble vitamins that dissolve in water.Common practice limits effectiveness
Many people in France take vitamin D supplements on an empty stomach, often with black coffee, which can reduce the amount of the vitamin actually absorbed by the body.Fatty meals improve absorption
Consuming vitamin D with a meal that includes fats can significantly enhance its absorption, as the body needs lipids to process and absorb fat-soluble nutrients effectively.Form of the supplement matters
Vitamin D supplements come in various forms, such as drops or oily capsules that contain carrier oils, which help with absorption, while dry tablets require more fat in the digestive system to be effective.
