Product description
SCIENCE INSPIRED BY NATURE


The only soya-protein based infant formula in the UK and Ireland.

A nutritionally complete formula, free from cows' milk, lactose and sucrose.

Suitable for vegetarians.
The first 1,000 days of a baby’s life have a life-long impact on many aspects of future health.
Protein is vitally important for a baby’s growth. Therefore, if a baby is intolerant to cows’ milk, an alternative must be found.
We offer the only soya-protein based infant formula in the UK & Ireland. Please note: SMA® Wysoy® is now available in an updated formula. The changes are slight differences in the nutritional values and not clinically significant. The changes are in line with the European Food Safety Authority's opinion on the essential composition of infant formula.
Galactosaemia is a rare inherited disorder which prevents the body breaking down the sugar galactose, found in milk. Babies with Galactosaemia require a galactose-free diet for life. Since both breast milk and standard infant formula milks contain galactose in the form of lactose then these must be excluded in the diet. Soya-based infant formula does not contain lactose (galactose) and is a safe choice for babies with galactosaemia.

How to open and prepare your baby’s feed
Whilst this product is made under strict hygienic conditions, it is not sterile. Failure to follow instructions on preparation and storage may make your baby ill.

1. Pull the safety seal and open the lid. Lift the tab, pull on the foil seal, carefully and safely remove the seal and dispose of it. The scoop is provided under the foil seal.

2. Wash hands well. Wash and sterilise all utensils according to manufacturers’ instructions.

3. Boil 1 litre of fresh tap water. Allow boiled water to cool for no more than 30 minutes. Measure the required amount of water (see feeding guide) into a sterilised bottle, carefully – the water is hot. Do not use artificially softened or repeatedly boiled water.

4. Using only the scoop provided, add the correct number of scoops of powder (see feeding guide), levelling off each scoop with the back of a clean dry knife. Replace plastic lid on can.

5. Place the sterilised teat and cap on the bottle and shake well until powder is fully dissolved. Cool bottle under cold running water or in a bowl or jug of cold water until lukewarm, do not immerse the teat. Test temperature by shaking a few drops onto the inside of your wrist.

Product leaflet

The World Health Organisation (WHO) has recommended that pregnant women and new mothers be informed on the benefits and superiority of breastfeeding – in particular the fact that it provides the best nutrition and protection from illness for babies. Mothers should be given guidance on the preparation for, and maintenance of, lactation, with special emphasis on the importance of a well-balanced diet both during pregnancy and after delivery. Unnecessary introduction of partial bottle-feeding or other foods and drinks should be discouraged since it will have a negative effect on breastfeeding. Similarly, mothers should be warned of the difficulty of reversing a decision not to breastfeed. Before advising a mother to use an infant formula, she should be advised of the social and financial implications of her decision: for example, if a baby is exclusively bottle-fed, more than one can (400 g) per week will be needed, so the family circumstances and costs should be kept in mind. Mothers should be reminded that breast milk is not only the best, but also the most economical food for babies. If a decision to use an infant formula is taken, it is important to give instructions on correct preparation methods, emphasising that unboiled water, unsterilised bottles or incorrect dilution can all lead to illness. SMA® Wysoy® milk‑free formula is intended to meet the nutritional needs of babies and children who are intolerant to cows’ milk protein, lactose or sucrose. Soya infant formulae are not recommended for preterm babies or those with kidney problems, where medical guidance should always be sought.
