2. Which vitamin can prevent neural tube birth defects?

Niacin

Vitamin E

Folic acid

Folic acid is the correct answer because it is known to prevent neural tube birth defects. Neural tube defects occur when the neural tube, which forms the baby's brain and spinal cord, does not develop properly. Folic acid is a B vitamin that helps the body make new cells, including the cells of the neural tube. Taking folic acid before and during pregnancy can significantly reduce the risk of neural tube defects in newborns. Niacin and vitamin E do not have the same protective effect against neural tube defects.

3. Which vitamin helps blood clot?

Vitamin C

Vitamin D

Vitamin K

Vitamin K is the correct answer because it plays a crucial role in blood clotting. It helps in the production of certain proteins that are necessary for the clotting process. Without sufficient vitamin K, the blood may not clot properly, leading to excessive bleeding or difficulty in stopping bleeding. Therefore, vitamin K is essential for maintaining proper blood clotting function in the body.

4. Which vitamin helps you see at night?

Vitamin A

Vitamin C

Vitamin K

Vitamin A is the correct answer because it plays a crucial role in maintaining good vision, particularly in low light conditions. It is essential for the production of a pigment called rhodopsin, which is found in the retina of the eye and helps with night vision. Without enough vitamin A, the eyes may struggle to adjust to darkness, leading to difficulty seeing in low light or at night. Therefore, consuming adequate amounts of vitamin A through diet or supplements is important for maintaining healthy vision, especially in dimly lit environments.

5. This vitamin is one of the most promising treatments for lowering cholesterol in the blood.

Vitamin B1

Vitamin B2

Vitamin B3

Vitamin B3, also known as niacin, is the correct answer. Niacin has been shown to effectively lower cholesterol levels in the blood. It works by reducing the production of LDL cholesterol (the "bad" cholesterol) and triglycerides, while increasing HDL cholesterol (the "good" cholesterol). Niacin is often used as a supplement to help manage high cholesterol and is considered one of the most promising treatments for this purpose. Vitamin B1 and B2 do not have the same cholesterol-lowering effects as vitamin B3.
