About this product
Abbott Similac Isomil Soy – Milk-Free Infant Formula for Lactose Intolerance & Milk Allergy Abbott Similac Isomil is a soy-based infant formula providing complete nutrition without any dairy or lactose — specifically designed for infants with lactose intolerance, galactosaemia, or cow’s milk protein allergy (where soy is tolerated).
Isomil is formulated to meet all nutritional requirements for infant growth and development using soy protein isolate as the protein source, with added vitamins, minerals, and essential fatty acids. Manufactured by Abbott to the same high standards as the Similac Gold range.
Key Features of Abbott Similac Isomil Soy Formula 100% dairy-free and lactose-free — suitable for lactose intolerance and galactosaemia Soy protein isolate as the sole protein source — no cow’s milk protein DHA and ARA for brain and visual development Calcium and Vitamin D for bone mineralisation in dairy-free feeding Complete micronutrient profile for normal infant growth from 0–12 months Uses of Abbott Similac Isomil Similac Isomil is used for infants with lactose intolerance, galactosaemia, cow’s milk protein allergy (when soy is tolerated under medical supervision), and infants in vegan or vegetarian families where parents choose not to use dairy-based formula.
All use cases should be guided by a paediatrician. How to Prepare Abbott Similac Isomil Sterilise all feeding equipment. Boil water and allow to cool to approximately 40°C. Add one level scoop (provided) per 30ml of water as directed on the pack for your baby’s age.
Mix gently until fully dissolved. Feed immediately and discard any unused formula after 1 hour.

Warnings & Precautions Not suitable for premature infants without specific medical approval. Soy formula is not recommended as a first-line treatment for cow’s milk protein allergy in infants under 6 months — a hydrolysed or amino acid formula may be more appropriate.
Always use under paediatric supervision. Contains phytoestrogens (soy isoflavones) — discuss with your doctor for long-term use. Possible Side Effects Soy formula is generally well tolerated. Some infants may experience constipation or gassiness. Up to 50% of infants with cow’s milk protein allergy may also react to soy — confirm tolerance with your paediatrician before committing to soy formula.
Frequently Asked Questions Is soy formula safe for infants? Soy-based formulas like Similac Isomil are nutritionally complete and considered safe for most term infants when used under medical supervision. Long-term safety of phytoestrogens in infant soy formula has been extensively studied with reassuring data.
Can Similac Isomil be used for cow’s milk allergy? Soy formula can be considered for cow’s milk allergy in infants over 6 months, but many infants with cow’s milk allergy also react to soy. A hydrolysed formula is usually the first choice — consult your paediatrician before switching.
Is soy formula suitable for lactose intolerance? Yes — Similac Isomil is completely lactose-free, making it appropriate for confirmed lactose intolerance or galactosaemia. Note that transient lactose intolerance (post-gastroenteritis) often resolves within 2–4 weeks and may not require a permanent formula switch.
Does soy formula affect hormone development? Soy contains phytoestrogens (isoflavones). While extensively studied, some parents and doctors prefer to limit phytoestrogen exposure in infants. Discuss with your paediatrician if you have concerns about long-term soy formula use.
Does Similac Isomil have the same DHA as Similac Gold? Similac Isomil contains DHA and ARA for brain and visual development, similar in concept to Similac Gold. However, it does not contain the HMO (2′-FL) technology found in the Similac Gold range. Disclaimer: Breastfeeding is recommended wherever possible.
Soy infant formula should be used under paediatric supervision. Always consult your doctor before switching infant formula, especially for allergy management.
