By Editorial Team | Updated October 8, 2026

Enfamil D-Vi-Sol is a liquid vitamin D supplement that provides 400 IU (10 mcg) of vitamin D3 per 1 mL serving. It is designed to help breastfed and partially breastfed babies meet their daily vitamin D needs, supporting calcium absorption and healthy bone development.

Its measured dropper and 50 mL bottle make daily supplementation straightforward. However, the 1 mL serving is larger than some single-drop alternatives, and not every baby likes the taste. This review explains its ingredients, proper dosing, safety considerations, and overall value.

Review Contents

Key Takeaways

• Enfamil D-Vi-Sol provides 400 IU (10 mcg) vitamin D3 in one 1 mL serving.
• Vitamin D supports calcium absorption and healthy bone and tooth development.
• A 50 mL bottle provides approximately 50 daily servings at the standard dose.
• The product can be given directly into the inner cheek or mixed with breast milk or formula.
• It contains no artificial colors or flavors and is gluten-free, according to the U.S. manufacturer.
• It is not necessary for every formula-fed baby, so dietary intake matters.

What Is Enfamil D-Vi-Sol?

Enfamil D-Vi-Sol is a liquid vitamin D3 supplement made by Mead Johnson for infants who need additional vitamin D. It provides the commonly recommended 400 IU daily amount in a measured serving.

The product is especially relevant for exclusively breastfed and partially breastfed infants. Breast milk usually does not provide enough vitamin D to meet an infant’s daily needs.

Unlike concentrated formulas that provide 400 IU in one small drop, D-Vi-Sol uses a 1 mL serving measured with the included dropper.

You can give it directly or add it to a small amount of breast milk or formula. The main goal is consistent daily intake, not providing more than the recommended amount.

Enfamil D-Vi-Sol Specifications

The key specifications are its vitamin D content, serving volume, and bottle capacity. These determine how you measure each dose and how long a bottle can last.

These specifications are supported by Mead Johnson’s U.S. product information. Packaging and labeling may differ between markets.

What’s in the Box?

• One 50 mL bottle of Enfamil D-Vi-Sol liquid vitamin D drops.
• A measuring dropper with a 1 mL mark.
• A child-resistant bottle cap and product instructions.

Check the packaging seal and expiration date before the first use. Do not use the product if its safety seal is broken or missing.

Why Babies Need Vitamin D

Babies need vitamin D to absorb calcium and build healthy bones and teeth. Adequate vitamin D also helps prevent rickets, a condition that causes bones to become soft and weak.

Breast milk supplies many essential nutrients, but it usually does not provide the recommended daily amount of vitamin D.

• Supports calcium absorption.
• Helps normal bone mineralization.
• Contributes to healthy tooth development.
• Helps maintain normal vitamin D status during infancy.
• Reduces the risk of vitamin D deficiency when used appropriately.

The CDC recommends 400 IU of vitamin D daily for infants younger than 12 months. Breastfed infants generally need supplementation beginning shortly after birth.

Infant formula already contains vitamin D. Babies drinking about 32 fl oz or more of fortified formula each day typically do not need an additional supplement.

Sunlight can help the skin produce vitamin D, but direct sun exposure is not a safe substitute for infant supplementation. Babies should be protected from excessive ultraviolet exposure.

How to Give Enfamil D-Vi-Sol Drops

Enfamil D-Vi-Sol is normally given as 1 mL once daily, unless your baby’s doctor recommends a different amount. Use the measuring dropper supplied with this product.

1. Wash your hands. Check the bottle label and expiration date.
2. Shake the bottle well. Follow the instructions printed on your specific bottle.
3. Measure the serving. Fill the supplied dropper to the 1 mL line.
4. Position your baby safely. Hold your baby upright or in a supported feeding position.
5. Dispense slowly. Gently release the liquid toward the inside of the cheek rather than the back of the throat.
6. Alternatively, mix the dose. Add it to a small amount of breast milk or prepared infant formula that your baby can finish.
7. Complete the routine. Follow the package’s dropper-care directions, close the bottle securely, and store it out of children’s reach.

Using a small feeding rather than a full bottle can help you know whether your baby received the entire serving. Do not add an extra dose if some liquid is spilled or spit out without asking a healthcare professional.

Can You Mix the Drops With Food?

According to the manufacturer, the supplement may be mixed with milk or suitable foods to improve acceptance. For babies already eating solids, a small serving of cereal may be an option.

Although the product directions also mention juice, the CDC advises against giving fruit or vegetable juice to babies younger than 12 months. Breast milk or formula is the better mixing choice for younger infants.

How Should You Store It?

Refrigeration is not required. Keep the bottle closed, away from direct light, and within the storage conditions listed on its packaging.

Store it where children cannot reach it. Keep the original bottle and instructions together so every caregiver can confirm the serving size.

Enfamil D-Vi-Sol Ingredients and Safety

Enfamil D-Vi-Sol contains vitamin D3 as its active nutrient, along with inactive ingredients that help produce a measurable liquid supplement.

The U.S. product information lists these inactive ingredients:

• Glycerin
• Water
• Polysorbate 80, an emulsifier
• Citric acid, used as an antioxidant
• Natural flavor
• Sodium citrate

According to Mead Johnson, the U.S. formula contains no artificial colors or flavors, is gluten-free, and does not contain ingredients derived from several common food allergens, including milk, egg, peanuts, tree nuts, fish, shellfish, soy, or wheat.

However, free from common allergen-derived ingredients does not mean a product is guaranteed safe for every allergy. Always examine the actual label if your baby has a known allergy or sensitivity.

Is Enfamil D-Vi-Sol Safe for Newborns?

Enfamil D-Vi-Sol is designed for infant vitamin D supplementation, including use from the newborn period when appropriate. The standard 400 IU daily amount aligns with U.S. pediatric recommendations.

Safety depends on using the correct product, concentration, and dose. Do not combine multiple vitamin D supplements unless your baby’s clinician has specifically recommended it.

Premature infants, babies with certain medical conditions, and infants receiving specialized nutrition may need individualized supplementation.

Who Should Buy Enfamil D-Vi-Sol?

Enfamil D-Vi-Sol is a reasonable choice for caregivers who want a measured daily vitamin D supplement rather than a highly concentrated one-drop formula.

Who It Suits

• Parents of exclusively breastfed infants who need vitamin D supplementation.
• Families using both breast milk and formula when their baby does not receive enough fortified formula to meet vitamin D needs.
• Caregivers who prefer a clearly marked 1 mL dropper.
• Parents who want the option to mix a supplement into breast milk or formula.

Who May Prefer Something Else

• Parents who want a single-drop formula with fewer inactive ingredients.
• Babies who consistently refuse the 1 mL liquid serving.
• Infants already receiving adequate vitamin D from formula or prescribed supplements.
• Families who need a specialized supplement recommended by their pediatrician.

Enfamil D-Vi-Sol Pros and Cons

The main advantages are its measured serving and established vitamin D content. The trade-offs are the larger serving volume and its multi-ingredient liquid formulation.

Enfamil D-Vi-Sol Dosing and Convenience

The included dropper is one of D-Vi-Sol’s most practical features. Its 1 mL marking helps caregivers measure the same amount each day without counting individual drops.

The trade-off is volume. A concentrated alternative may deliver the same 400 IU in one small drop, while D-Vi-Sol requires a full milliliter.

For babies who accept liquid supplements easily, this difference may be minor. For babies who spit out part of a serving, it can make daily use less convenient.

Does the Formula Offer Special Immune Benefits?

Vitamin D contributes to normal immune function, but D-Vi-Sol should not be treated as a medicine that prevents common infections.

The strongest reason to use it is to help meet daily vitamin D requirements and support normal bone development. Do not assume additional benefits beyond established vitamin D nutrition.

How Long Does the Bottle Last?

The 50 mL bottle provides approximately 50 servings at 1 mL daily. That is about seven weeks of routine use.

The actual duration may be slightly shorter if liquid is spilled or left unused in the dropper. The marked serving size should never be reduced simply to make the bottle last longer.

Best Uses for Enfamil D-Vi-Sol

Exclusively Breastfed Babies

Breastfed infants are a primary group for daily vitamin D supplementation. D-Vi-Sol supplies 400 IU in one measured serving.

Parents can give the liquid directly or mix it into a small amount of expressed breast milk.

Babies Receiving Both Breast Milk and Formula

Partially breastfed infants may need supplemental vitamin D depending on how much fortified formula they consume.

Keep track of approximate daily formula intake and discuss changing needs with your baby’s clinician.

Families Sharing Feeding Responsibilities

A measured dropper and consistent daily routine can help different caregivers follow the same instructions.

Keep the bottle in its original packaging and clearly communicate when the day’s serving has already been given. This helps reduce accidental duplicate doses.

What Parents Report About Enfamil D-Vi-Sol

Customer feedback generally highlights the convenience of the measured dropper and the ability to mix the supplement with milk. However, acceptance varies between babies.

Individual reviews are personal reports, not proof of a medical outcome or product effectiveness.

Positive Feedback

• Some parents say the marked dropper makes the amount easy to measure.
• Caregivers report mixing the supplement into breast milk or formula without disrupting their feeding routine.
• Several parents appreciate the flexibility of giving the liquid directly or in a bottle.
• Some reviewers report that their babies accept the taste without difficulty.

Common Watch-Outs

• Taste acceptance is inconsistent, and some babies may spit out the supplement.
• One parent reported leakage when the bottle was stored on its side.
• The 1 mL serving can be less convenient than concentrated single-drop formulas.
• Measuring and administering the supplement requires attention during busy feeding routines.

These observations reflect customer comments on the Enfamil D-Vi-Sol retail listing and reviews and other published retailer feedback. Some reviews were collected through promotions. Experiences should not be assumed to represent every family.

Enfamil D-Vi-Sol vs. Other Baby Vitamin D Drops

Several infant vitamin D products supply the same 400 IU daily amount but use different serving volumes and ingredients. The most useful comparison is how easily you can give the correct dose.

Enfamil D-Vi-Sol vs. Baby Ddrops

Baby Ddrops provides 400 IU in a single drop, using vitamin D3 and a coconut-derived oil carrier. Its small serving may appeal to families who find a full milliliter difficult to administer.

D-Vi-Sol may feel easier for caregivers who prefer measuring a marked liquid volume rather than dispensing exactly one concentrated drop.

Enfamil D-Vi-Sol vs. Mommy’s Bliss

Mommy’s Bliss Organic Vitamin D Drops provide 400 IU in one drop and use organic MCT oil as a carrier.

Mommy’s Bliss instructs caregivers not to dispense its concentrated drops directly into an infant’s mouth. Administration directions therefore differ from D-Vi-Sol, even though the vitamin D amount per serving is the same.

Enfamil D-Vi-Sol vs. Carlson Baby’s Super Daily D3

Carlson Baby’s Super Daily D3 also supplies 400 IU in one drop. It is an option for parents who prefer a small, unflavored serving.

Neither format is automatically better for every infant. The right choice depends on the product’s ingredients, your child’s acceptance, and your ability to give the proper dose consistently.

Is Enfamil D-Vi-Sol Worth Buying?

Enfamil D-Vi-Sol is worth considering if your baby needs supplemental vitamin D and you prefer a measured liquid serving. It provides the recommended 400 IU amount and offers flexible administration.

The 50 mL bottle supplies approximately 50 daily servings, so you can compare its current price against the total number of doses.

For the best value comparison, calculate cost per 400 IU serving rather than comparing bottle volume alone. Concentrated single-drop alternatives may look smaller but contain many daily servings.

Its limitations are also clear. The 1 mL serving is larger than concentrated alternatives, and the formula contains several inactive ingredients.

The product does not qualify for purchase with SNAP food benefits because it is a dietary supplement labeled with Supplement Facts, rather than an eligible food item.

Overall, it is a practical choice for many breastfeeding families, provided they follow the correct dosing instructions and their clinician agrees that supplementation is needed.

Frequently Asked Questions

How long does one bottle of Enfamil D-Vi-Sol last?

A 50 mL bottle of Enfamil D-Vi-Sol provides approximately 50 daily servings when used at 1 mL per day. That is about seven weeks. The actual number may be slightly lower if some liquid is spilled or wasted during administration.

Can Enfamil D-Vi-Sol be purchased with SNAP benefits?

No. Enfamil D-Vi-Sol is a dietary supplement with a Supplement Facts label. USDA rules exclude vitamins, medicines, and supplements from SNAP-eligible purchases. Other forms of payment or assistance may be available, but SNAP food benefits cannot be used for this product.

What is the recommended daily vitamin D amount for breastfed babies?

Breastfed babies generally need 400 IU (10 mcg) of vitamin D daily beginning shortly after birth. The CDC and American Academy of Pediatrics recommend this amount to support healthy bones and prevent deficiency. Ask your pediatrician if your baby has special nutritional needs.

Does Enfamil D-Vi-Sol contain artificial colors or flavors?

No. Mead Johnson states that its U.S. Enfamil D-Vi-Sol formula does not contain artificial colors or flavors. It does contain natural flavor and other inactive ingredients, including glycerin and polysorbate 80. Check your bottle because ingredient lists may differ between markets.

Can Enfamil D-Vi-Sol be mixed with cereal or juice?

Yes, the manufacturer allows mixing D-Vi-Sol with suitable foods, including cereal, or with breast milk and formula. However, juice is not recommended for babies younger than 12 months. For younger infants, mixing the measured serving with a small amount of breast milk or formula is preferable.

Do formula-fed babies need Enfamil D-Vi-Sol?

Not always. Babies who consume about 32 fl oz or more of vitamin D-fortified infant formula daily generally do not require additional vitamin D. Babies receiving smaller amounts may need supplementation. Discuss your baby’s actual intake with a healthcare professional before adding another vitamin.

Is one drop of Enfamil D-Vi-Sol enough?

No. The standard Enfamil D-Vi-Sol serving is 1 mL, measured with the included dropper, to provide 400 IU of vitamin D. One ordinary drop is not the full serving. Do not confuse these directions with concentrated supplements that deliver 400 IU in one drop.

Does Enfamil D-Vi-Sol need to be refrigerated?

No. The manufacturer’s U.S. instructions state that refrigeration is not required. Store the bottle away from direct light and follow the storage directions on its label. Keep it tightly closed, use it before the expiration date, and store it out of children’s reach.

What if my baby spits out the vitamin D drops?

If your baby spits out some of the serving, do not automatically repeat the full dose. It may be difficult to know how much was swallowed. Ask your pediatrician about the appropriate next step and whether mixing future servings with a small amount of milk would help.

Conclusion

Enfamil D-Vi-Sol offers a straightforward way to provide 400 IU of vitamin D3 daily to infants who need supplementation. Its measured dropper, 50-serving bottle, and flexible administration are useful features.

Its main limitations are the 1 mL serving and the presence of several inactive ingredients. Parents seeking a more concentrated option may prefer single-drop products.

For families who value a measured liquid format, D-Vi-Sol remains a reasonable option. Confirm your baby’s vitamin D needs with a pediatrician and follow the serving instructions on the actual bottle.
