Vitamin A is thought to interfere with the _____.Multiple choice question.absorption of vitamin Kdecrease in the activity of vitamin Kexcretion of vitamin K

The question asks about the relationship between Vitamin A and Vitamin K, specifically how Vitamin A might interfere with Vitamin K in the body. Let's analyze each option provided:

1. Absorption of Vitamin K: This option suggests that Vitamin A may hinder the body's ability to take in Vitamin K from dietary sources. Both vitamins are fat-soluble, which means they require dietary fats for absorption. There is some evidence that excessive amounts of Vitamin A can affect the absorption of Vitamin K, but this can depend on various factors such as dosage and individual nutritional status.

2. Decrease in the Activity of Vitamin K: This option proposes that Vitamin A might reduce the effectiveness or functional action of Vitamin K in the body. While the two vitamins can interact, the specific mechanism suggesting that Vitamin A decreases the biological activity of Vitamin K is less commonly discussed in the literature.

3. Excretion of Vitamin K: This implies that Vitamin A increases the elimination of Vitamin K from the body. Generally, here too, there's limited evidence indicating that Vitamin A directly affects the excretion rate of Vitamin K.

Upon considering these options, the most supported statement in nutritional science would be:

Final Answer: Absorption of Vitamin K.
