Question 1 – Which vitamin deficiency can make the body internally weak or "hollow"?

Question 2 – What vitamin deficiencies can lead to chapped or dry lips?
Answer: Chapped lips can result from a lack of several B-complex vitamins, including Folate (B9), Riboflavin (B2), Vitamin B6, and Vitamin B12. These nutrients support skin and tissue health, and their absence may cause skin dryness and cracking around the mouth.

Question 3 – Which vitamin deficiency causes the body to feel weak?
Answer: Again, Vitamin B12 is the primary vitamin associated with physical weakness. It plays a central role in maintaining energy levels and supporting nerve function.

Question 4 – What part of the body never rests?
Answer: The human heart is the only organ that never rests. It beats continuously, pumping blood throughout the body, day and night, without any pause.

Question 5 – Which vitamin deficiency is linked to yellowing of teeth?
