BetterYou Spray Dlux Infant

What Are Vitamin D Drops for Infants and Why Do Babies Need Them?

If you're a new parent, you've probably heard a lot about vitamin D — and for good reason. The NHS recommends that all babies from birth to one year old receive a daily vitamin D supplement of 400 IU, regardless of whether they are breastfed or formula-fed (unless they are drinking more than 500 ml of infant formula per day, which is already fortified). Vitamin D drops for infants have traditionally been the go-to format, but oral sprays are increasingly popular because they're easier to administer and less messy. BetterYou Spray Dlux Infant offers exactly that — a simple, once-daily oral spray delivering 400 IU of vitamin D3 per dose.

Vitamin D is essential for healthy bone development, immune function, and muscle health in young children. Because the UK has limited sunlight for much of the year, and because breast milk contains very little vitamin D, deficiency is a genuine concern. Rickets — a condition caused by severe vitamin D deficiency — remains a public health issue in the UK, which is why supplementation is so strongly recommended.

How Does BetterYou Spray Dlux Infant Work?

Unlike traditional drops that are swallowed and absorbed through the gut, this oral spray works by delivering vitamin D3 directly onto the soft tissue inside your baby's cheek. The active ingredient — cholecalciferol (vitamin D3) — is then absorbed through the oral mucosa into the bloodstream. Here's how the process works:

• One spray is directed onto the inner cheek lining.
• Cholecalciferol is absorbed through the mucosal tissue.
• It travels via the bloodstream to the liver, where it is converted to 25-hydroxyvitamin D.
• The kidneys then convert this to the active form, calcitriol, which supports calcium absorption and bone mineralisation.

This transmucosal absorption route can be particularly useful for infants whose digestive systems are still maturing, as it reduces reliance on gut absorption efficiency.

Who Should Use BetterYou Spray Dlux Infant?

This product is designed for babies and young children. The NHS advises vitamin D supplementation for all infants from birth, and this spray is a practical option for parents who find liquid drops fiddly to measure. It is especially relevant for:

• Breastfed babies from birth to one year, as breast milk is low in vitamin D.
• Formula-fed babies consuming less than 500 ml of formula per day.
• Children aged one to four years, who are advised to take 400 IU of vitamin D daily.
• Families living in northern parts of the UK, where sunlight exposure is particularly limited.

If your child has a diagnosed medical condition affecting calcium or vitamin D metabolism — such as hyperparathyroidism or sarcoidosis — speak to your GP before starting supplementation. You may also find our baby and toddler range helpful for other everyday health essentials.

How Does BetterYou Spray Dlux Infant Compare to Traditional Vitamin D Drops?

Is BetterYou Spray Dlux Infant Safe to Store and Use Daily?

Yes — when used as directed, this spray is considered safe for daily use in infants and young children. The dose of 400 IU per spray aligns precisely with NHS and SACN (Scientific Advisory Committee on Nutrition) recommendations. It is important not to exceed one spray per day, as excessive vitamin D intake can lead to hypercalcaemia. Store the bottle below 25°C, away from direct sunlight, and keep it out of reach of children when not in use.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Is BetterYou Spray Dlux Infant and What Is It Used For?

BetterYou Spray Dlux Infant is an oral vitamin D3 spray formulated specifically for babies and young children. Each spray delivers 400 IU of cholecalciferol — the same form of vitamin D that the body produces naturally in response to sunlight. It is used to prevent vitamin D deficiency in infants, which can otherwise lead to poor bone development, weakened immunity, and in severe cases, rickets. The NHS recommends that all babies from birth to one year receive a daily vitamin D supplement, and this spray provides a convenient, measured way to meet that recommendation.

What Do You Need to Know Before Using BetterYou Spray Dlux Infant?

Before giving this supplement to your baby, there are a few important things to be aware of. While it is generally very safe at the recommended dose, certain conditions and circumstances require extra caution.

Do not use if your child:

• Has been diagnosed with hypercalcaemia (high blood calcium levels).
• Has a condition causing abnormal calcium or vitamin D metabolism, such as sarcoidosis or hyperparathyroidism.
• Is already receiving a vitamin D supplement providing 400 IU or more per day — do not double up.
• Is allergic to any of the ingredients, including sunflower oil or natural flavourings used in the formulation.

Drug interactions to be aware of:

• Thiazide diuretics (used in some heart and blood pressure conditions) may increase the risk of hypercalcaemia when combined with vitamin D supplements.
• Certain anti-epileptic medicines (such as phenytoin or phenobarbitone) can reduce vitamin D levels, but dose adjustments should only be made under medical supervision.
• At the standard 400 IU infant dose, clinically significant interactions are uncommon — but always inform your GP or pharmacist of all supplements your child is taking.

How Should You Use BetterYou Spray Dlux Infant?

Using this spray correctly ensures your baby receives the right amount of vitamin D every day. It's straightforward, but a few steps make all the difference.

1. Shake the bottle gently before each use.
2. Hold the bottle upright and direct the nozzle towards the inside of your baby's cheek.
3. Press the pump once to release a single spray.
4. Do not spray directly onto the back of the throat.
5. Replace the cap securely after use.

Formula-fed babies who are consuming more than 500 ml of infant formula per day do not typically require an additional supplement, as formula is already fortified with vitamin D. If you're unsure, speak to your health visitor or pharmacist. You might also find it useful to explore our wider baby and toddler health range for other everyday essentials.

What Are the Possible Side Effects of BetterYou Spray Dlux Infant?

At the recommended dose of one spray per day (400 IU), side effects are extremely unlikely. Vitamin D3 at this level is well tolerated in healthy infants. However, it is worth knowing what to look out for, particularly if the product is accidentally overused.

Common side effects (at recommended doses, these are rare):

• Mild skin irritation around the mouth in sensitive infants — this is uncommon and usually transient.

Less common side effects (associated with excessive intake only):

• Hypercalcaemia — symptoms include nausea, vomiting, constipation, excessive thirst, and frequent urination.
• Loss of appetite or unusual irritability in infants.
• In very rare cases of prolonged excessive intake: soft tissue calcification.

If you accidentally give more than the recommended dose on a single occasion, it is unlikely to cause harm, but contact NHS 111 or your GP for advice if you are concerned.

How Should You Store BetterYou Spray Dlux Infant?

Correct storage helps maintain the product's quality and safety throughout its shelf life. Follow these guidelines:

• Store below 25°C in a cool, dry place.
• Keep away from direct sunlight and heat sources.
• Do not refrigerate unless stated on the packaging.
• Always keep the cap on tightly when not in use.
• Keep out of reach and sight of children.
• Do not use after the expiry date printed on the bottle.
