## Overview

Similac Isomil Advance Soy Formula is a nutritionally complete, iron-fortified, soy-based infant formula designed to support brain and eye development with its exclusive OptiGRO blend of DHA, Lutein, and Vitamin E. Naturally lactose-free and clinically shown to reduce common feeding issues like fussiness and gas, it’s the #1 infant formula brand fed in hospitals, trusted by parents and professionals alike.

## Description

Soy-based formulas have been clinically shown to help reduce common feeding problems such as fussiness and gas when switching from milk-based formula. Similac Soy Isomil has nucleotides inherent in soy protein for your baby’s developing immune system and prebiotics to help support the digestive system. Our gentle soy formula features our exclusive blend of DHA, lutein, and vitamin E, important ingredients found in breast milk. DHA supports brain development, lutein supports eye development, and vitamin E is an important nutrient that supports developing cells. Similac is the #1 infant formula brand fed in hospitals. Soy-based formulas are not recommended for premature infants with birth weights less than 1800 g.

Review: Well received - Of all the brands of soy formula I have tried, Similac brand is the easiest to use. In comparison to Enfimil and Earth's Best this product dissolved the best. I typically use prewarmed water that isn't boiling. The powder easily dissolved with minimal shaking. Enfimil and Earth's Best you need to vigorously shake and even then you may still get clumps unless you are using water that is right around the point of boiling in temperature. We should use this temperature to sterilize the powder but it should not be required to prevent clumping. The price of this formula is reasonable and actually cheaper than Enfamil. My state has a contract with Enfamil for WIC which increases the price of their products for this size can by ten dollars. I would purchase Similac powder soy formula in store but it's so hard to find. We do carry the contracted cans but they are pricey at 8-9 dollars for a can that has enough servings for a single day. I haven't noticed any adverse reactions to this formula. It's a quality product, dissolves well and is well received. Overall, I would recommend this brand of soy formula. Update March 24, 2023 This soy formula, however well received it is, isn't the best. I don't know what does to make this product but it always produces a more frequent green bowel movement. Earth's best and Enfamil do not have this effect. I even got ahold of Gerber Soy which has an overall better ingredient list also. I'm still nursing and my daughter has started solids. Going back to the other mentioned brands her bowels is less frequent and more mustard colored. This tells me that Similac is full of inferior ingredients. Like ok, formula isn't breastmilk but I have to say this is the worst soy ingredient wise. It's a good product in a pinch but definitely not my first choice for a soy formula. I personally wouldn't recommend it either if other options is more available.
Review: Put less scoops for a happy newborn - I wanted to let people know so your baby won’t be constipated or have any colic in 3 ounces of water put 1 scoop of the powder. For 4 ounces I put 1 1/2 scoops . That’s how the doctor recommended my grandmother give it to my mom, and that’s how I will be giving it to my son since 2 scoops in 4 ounces was giving him terrible colic after reducing the dosage he was able to poop and sleep without pain.
