Product Description

Gelmix Infant Thickener for Breast Milk and Formula, Pediatric Choice for Reflux and Dysphagia

*#1 Pediatric Choice. Gelmix is the only thickener recommended for both breast milk & formula, according to Duncan, D. R., Larson, K., & Rosen, R. L. (2019). Clinical aspects of thickeners for pediatric gastroesophageal reflux and oropharyngeal dysphagia. Current gastroenterology reports, 21(7), 6.

Made for use with infants born term weighing at least 6 pounds.

Do not use Gelmix with preterm infants until they have reached at least 6 pounds and a corrected age of 2 weeks (aka 42 weeks postmenstrual age).

Organic, Kosher, GMO free & Vegan. Does not contain any common allergens, including corn, soy, gluten and dairy. No xanthan gum.

Gelmix is USDA certified organic by QCS (2021) and certified Kosher by Kosher Organics (2021).

Wash Your Hands

bottle warmer, start with warm infant milk

mix well, shake up bottle

wait 5-10 minutes

Always wash hands with soap & water before preparation.

Pour desired amount of lukewarm liquid (about 100°F) into bottle. Freshly expressed breast milk at body temperature is sufficient.

Wait 5-10 minutes until desired consistency is reached. Mix again before feeding. Always test temperature before feeding.

FAQ Gelmix

Which Consistency Should I use?

If thickening is recommended to reduce spit-ups, a slightly thick consistency is usually effective. Start with one scoop (1.2g) per 3-4 oz. of warm milk and increase as needed.

If thickening is recommended due to swallowing difficulties, carefully follow your healthcare provider's instructions on which consistency to safely thicken up to. Usage instructions are designed for use with the IDDSI framework.

Can I Prepare in Advance?

Most liquids can be prepared up to 24 hours in advance and rewarmed for feeding. If served cold, the consistency will be thicker. Always follow CDC guidelines on safe handling and storage of breast milk and formula. It is not typically recommend to rewarm breast milk more than once.

Why is there a range in the usage instructions?

There are natural variations between formulas. Breast milk and elemental formulas tend to need more thickener than regular infant formulas to achieve desired consistency.

Massive Improvement With Spitting Up
5 Stars
Massive Improvement With Spitting Up
My baby had issues with spitting up and we tried everything to help and nothing worked. I can’t breastfeed and was using really good organic formula. I changed the formula brand and that didn’t work, I tried different techniques and they didn’t work. I ended up finding this and I’ve seen a massive improvement! It’s actually really easy to use despite what other reviews say, throw in a scoop or two depending on bottle amount and preferred thickness (we started with a scoop and tweaked it from there to what worked best for our daughter) , cover and shake it. Let sit for a few minutes and it’s all set. I haven’t had any issues with it and it’s been great! My daughter is now 2 months old and is doing a lot better.The moment I ran out and had to wait for another jar to arrive she was spitting up again so I know for a fact that it’s the gel mix that’s actually worked.
