Why Vitamin D Drops for Infants

Vitamin D drops are essential for infants. They support bone health, immune function, and brain development.

Vitamin D is crucial for infants’ growth. Many infants do not get enough from sunlight or diet. This blog explores why vitamin D drops are necessary, backed by expert opinions and guidelines.

The Role of Vitamin D

Vitamin D helps absorb calcium and phosphorus. These minerals build solid bones. Without enough vitamin D, infants can develop rickets. Rickets softens and fragileens bones. Vitamin D also boosts the immune system and supports brain development. According to a study, vitamin D has mental health benefits too.

Recommendations for Supplementation

The American Academy of Pediatrics (AAP) advises all breastfed infants to get 400 IU of vitamin D daily. Formula-fed infants need this if they drink less than 32 ounces of formula daily. This dosage prevents rickets and keeps vitamin D levels adequate. Studies support this recommendation (BabyCenter).

Sources of Vitamin D


Sunlight is a natural source of vitamin D. However, it is unreliable for infants. Their skin is sensitive to sun exposure. Sunscreen, necessary for protection, limits vitamin D production. Thus, sunlight alone is not enough (Cleveland Clinic).

Dietary Sources

Breast milk lacks sufficient vitamin D. Formula-fed infants get enough if they drink 32 ounces of fortified formula daily. Otherwise, they need supplements. As infants grow, foods like yogurt, cereal, and eggs can help meet vitamin D needs (CDC).

Types of Vitamin D Drops

Vitamin D drops come in diluted and concentrated forms. Diluted formulas need a dropperful. Concentrated ones need just a single drop. Drops can be placed on a nipple, pacifier, or mixed with milk or food. Follow the supplement label for correct dosage (BabyCenter).

Safety and Efficacy

Most vitamin D supplements in the U.S. are safe for infants. Choose a supplement with 400 IU of vitamin D3 per dose. It should have minimal other ingredients. Some drops need refrigeration, but non-refrigerated options are more convenient (BabyCenter).

Avoiding Excessive Supplementation

Too much vitamin D can cause hypercalcemia. This condition means too much calcium in the blood. It can be harmful. Stick to the recommended dosage. Vitamin D3 is preferred over D2 for its potency and longer duration in the body (Health Planet).

Expert Opinions and Guidelines

American Academy of Pediatrics (AAP)

The AAP recommends 400 IU of vitamin D daily for infants. This prevents rickets and maintains adequate vitamin D levels (Health Planet).

Endocrine Society

The Endocrine Society suggests higher vitamin D intake for children, pregnant persons, and older adults. For healthy adults under 75, they do not recommend routine testing or extra supplementation (Endocrine Society).

Practical Considerations

Choosing the Right Supplement

Parents should choose third-party tested supplements. They should be free from preservatives, artificial flavors, and colors. The product should be easy to administer and affordable (Healthline).

Administration Methods

Vitamin D drops can be given in various ways. Place a drop on the nipple, bottle, or mix with milk or food. Follow the product’s instructions. Consult a pediatrician if needed (BabyCenter).
