Casein and Whey are two different groups of proteins which are present in both breastmilk and cows' milk. The protein component of breastmilk is predominantly whey proteins. Whey proteins are thought to be more easily digested than casein proteins. For this reason, most infant formulas suitable from birth (starter formulas) are whey dominant (60% whey:40% casein).

Heinz Nurture® Starter Infant Formula and Heinz Nurture Gold Toddler® Starter Infant Formula are both whey dominant infant formulas with a whey to casein ratio similar to breastmilk. (60:40).

Heinz Nurture® Follow-On Formula and Heinz Nurture Gold Toddler® Follow-On Formula are casein dominant formulas. These formulas have a whey:casein ratio similar to cows' milk (20:80) which makes it slower to digest and therefore more suitable for infants over 6 months of age.

Nucleotides are nutrients naturally present in our bodies which are also found in breastmilk. They may play a role in developing strong immune systems and have a number of different functions that support growth and development.
Some infant formulas may contain up to five different types of nucleotides.

Heinz Nurture® contains nucleotides.

If these have been added, they will be listed in the ingredients list and the nutrition information panel.

Gold formulas contain added Long Chain Polyunsaturated Fatty Acids (LCPs). LCPs are part of two families of fatty acids called: the omega-3 and the omega-6 series. The two LCPs added to Gold formulas are Docosahexaenoic Acid (DHA), an omega-3 fatty acid and Arachidonic Acid (ARA), an omega-6 fatty acid. ARA and DHA are naturally present in several foods, including breastmilk.

Both adults and babies need LCPs. There are a number of studies that suggest that the addition of DHA in formula, in particular, may help brain and visual development.

Bifidus is a friendly (probiotic) bacteria found in our gut, which helps encourage healthy digestion and supports natural defenses against harmful bacteria. A healthy balance of ‘friendly’ bacteria in the gut can help in the development of babies’ immune system.

Bifidobacterium probiotics are naturally found in the gut of breast fed infants. ‘Bifidus’ (Bifidobacterium lactis) is added to Heinz Nurture Gold Toddler® Infant formula and Heinz Nurture Gold Toddler® Follow on formula.
