How are water-soluble vitamins primarily absorbed in the body?

Water-soluble vitamins, which include the B-complex vitamins and vitamin C, are primarily absorbed in the intestines during digestion. When food is broken down in the digestive system, these vitamins dissolved in the watery components of food are absorbed into the bloodstream, allowing them to be transported to various tissues throughout the body.

This absorption process emphasizes the importance of consuming a balanced diet that includes sources of these vitamins. The body does not store water-soluble vitamins; therefore, they need to be consumed regularly to maintain adequate health. The other response options do not accurately reflect the physiological process involved in the absorption of water-soluble vitamins. For instance, water-soluble vitamins are not absorbed through dietary fats, nor are they exclusively absorbed in the stomach, and they do not rely solely on supplementation for adequate levels in the body.
