Yes it is fairly serious, it is supprising he doesn't get sick a lot.
The only prescription I am aware of is Anadrol, unless they simply advise him of foods containing vitamins to help him out.

The incidence of iron deficiency anemia, rickets, and zinc deficiency is very high in Chinese preschool children and a method for prevention is urgently needed. From our studies, it can be seen that a soft drink powder is a convenient vehicle for the supplementation of iron, zinc, calcium, vitamin D, riboflavin, and ascorbic acid. Table salt is also a good, low-cost carrier for iron and zinc, and cow's milk can only be used for the enrichment of vitamins A and D. In our study the therapeutic dose of iron was lower than 3 mg/kg body weight recommended by the WHO Expert Committee. As ascorbic acid can enhance the absorption of iron in the body, so 300 mg vitamin C was added to 100 g of soft drink powder containing 100 mg of elemental iron. Ten g of powder is not only enough for the prevention of iron deficiency anemia but it can also cure iron deficiency anemia within 3 months. One hundred mg of iron in 100 g of table salt is an adequate level, because an adult or a child taking 10 or 5 g of salt will receive 10 and 5 mg of elemental iron respectively. This dosage is adequate for the prevention of anemia. From our results, 10 mg of zinc daily is enough for the prevention and treatment of zinc deficiency in preschool children. Four hundred IU of vitamin D (from fortified soft drink powder or enriched fresh cow's milk) orally-administered daily, is a good way to prevent rickets in infants and young children.
