General Mixing Questions

Why is it necessary to heat up liquids before mixing in Gelmix?

It is required to warm infant milk to allow Gelmix to dissolve entirely and ensure a lasting viscosity. For best results, warm the liquid to 100°F before mixing in Gelmix. Freshly expressed milk at body temperature or warmed to body temperature works well. Be careful not to overheat the liquid; excessive heat may cause the Gelmix to clump and may reduce the nutritional balance of infant milk.

What kinds of liquids will Gelmix thicken?

Gelmix is formulated for breast milk and infant formulas, but will effectively thicken any liquids that can be warmed up to 100°F first.

How thick can Gelmix make liquids?

Gelmix effectively thickens liquids to moderately thick (aka honey). Moderately thick liquids are more difficult to pass through a nipple/teat and are NOT typically recommended for infants. This difficulty may increase risk of dehydration due to poor oral intake. Remember, always consult a medical professional before thickening liquids to ensure it is appropriate for your infant’s individual needs.

I’m getting clumps, what can I do to prevent that?

Work quickly to avoid clumps. When the Gelmix sits in the liquid for too long without mixing, it starts to bind with the liquid and is more difficult to assimilate. Extremely hot liquids are also more difficult to assimilate with the Gelmix.

Thickening Breast Milk or Formula

Is it safe to warm breast milk?  How should I do it?

Gelmix mixes best in liquids warmed to about 100°F.  Freshly expressed breast milk at body temperature (around 98.6°F) will suffice. Thawed breast milk can be safely brought back to that temperature by placing it in a bottle and then placing the bottle in a bowl of warm water until lukewarm. Breast milk should not be warmed more than once to prevent damaging the nutritional balance of the milk.

Can I mix breast milk ahead of time with Gelmix?

Since Gelmix must be mixed with warmed milk, it is important to use caution when preparing in advance. Gelmix mixed with warmed breast milk may be stored in a sealed container at room temperature (up to 77°F) for up to 4 hours. Gelmix mixed with freshly expressed milk at body temperature may be stored in the refrigerator for up to 24 hours. Stored breast milk should never be warmed more than once, otherwise the nutrient value of the milk may be damaged. Read more info about storing breast milk here.

What is the best way to mix Gelmix with breast milk that does not involve shaking?

Gelmix will dissolve in breast milk at body temperature (freshly expressed or warmed), so you just need to swirl it gently to mix Gelmix in thoroughly. Although vigorous shaking could potentially take away the natural qualities of proteins present in breast milk, such as lysozyme and other proteins, gently swirling does not exert enough force to break the amino acid bonds of those proteins. We often recommend Easy Swirl Gentle Mixer to gently swirl Gelmix with infant milk without exerting much force.

Is it safe to heat up formula?

According to formula manufacturers, the temperature required to dissolve Gelmix is not high enough to affect the nutrients in formula. However, they recommend against heating up formulas containing probiotics. Always follow your formula manufacturer’s instructions on heating and reheating formula.

Can I mix formula ahead of time with Gelmix?

Most formulas can be mixed in advance with Gelmix and the mixture will remain thick after they are mixed. Always follow your formula’s preparation and storage instructions first.

For powder formulas, you may prepare just warmed water and Gelmix in advance, then store the thickened water in a sealed, sterile container at room temperature for up to 24 hours. When you’re ready to feed, just add the powder formula to the pre-thickened water.

What if my infant experiences gassiness or loose stools when starting Gelmix?

Transient gassiness and loose stools are a common side effect among infants using Gelmix for the first time. Gassiness usually subsides within two weeks of use or by reducing the amount used.

Do I need to change the nipple size for thickened feeds?

Always check nipple flow as it may be necessary to adjust the nipple size for thickened feeds. If your infant appears to be working too hard to get the milk out of the bottle, consult your pediatrician or feeding therapist. about trying one size bigger. Not all babies have the same strength or drive, so it is not an exact science.

The label on Nutramigen says it should not be heated. Can I use Gelmix with it?

Nutramigen LGG contains a type of probiotic that cannot withstand heat, if you want to preserve this probiotic, Gelmix should not be used with this type of Nutramigen.

Nutramigen Lipil’s manufacturer says it is safe to heat up to 100.0°F; at this temperature Gelmix should dissolve as long as the bottle is mixed properly.

Can Gelmix be used with preterm infants?

Gelmix is contraindicated for preterm and low birth weight infants until they have reached a minimum weight of six pounds and a corrected age of 2 weeks (often referred to as 42 weeks postmenstrual age)
