What is the process of excess intake of vitamin known as?

The correct answer is option 1. Hypervitaminoses.

The process of excess intake of vitamins, particularly fat-soluble vitamins that can accumulate in the body, is known as hypervitaminosis.

Hypervitaminosis: This refers to the condition caused by excessive intake of vitamins, especially fat-soluble vitamins (A, D, E, K), which can accumulate in the body’s tissues and lead to toxic effects. For example:

Vitamin A: Excessive intake can lead to symptoms like nausea, headaches, and liver damage.

Vitamin D: Overconsumption can cause hypercalcemia, leading to bone pain, kidney stones, and cardiovascular problems.

Avitaminosis: This term refers to a condition caused by a deficiency or lack of vitamins. For example, scurvy is caused by a deficiency of Vitamin C.

Renaturation: This is the process by which a denatured protein returns to its original, functional shape after denaturation. It is not related to vitamin intake.

Denaturation: This refers to the alteration of the structure of a protein (or nucleic acid) from its native state, often due to factors like temperature or pH changes. It does not pertain to vitamin intake.

Summary: Hypervitaminosis is the correct term for the condition resulting from excessive intake of vitamins.
