Quick answer
Similac Alimentum is a hypoallergenic infant formula designed for babies with protein sensitivities or food allergies, available in ready-to-feed liquid and powder forms.
Why choose Similac Alimentum for allergies?
Standard infant formulas contain intact proteins that can trigger colic symptoms in babies with protein sensitivities or food allergies. Similac Alimentum uses extensively hydrolyzed proteins, which are broken down into smaller pieces, making them easier to digest and less likely to cause an allergic reaction.
This formula is nutritionally complete for babies from birth to 12 months, so it can serve as a sole source of nutrition or a supplement. It is unflavored, which helps avoid additional taste sensitivities.
Powder vs. liquid: Which form suits your baby?
Similac Alimentum is available as a 12.1 oz can powder and a 2 oz ready-to-feed bottle liquid. The powder offers cost savings per serving and is convenient for mixing larger batches, but requires careful preparation with clean water and proper storage. The liquid is more expensive per ounce but eliminates mixing and is ideal for on-the-go use or when water quality is a concern.
Both forms provide the same hypoallergenic, extensively hydrolyzed protein formula. Your choice depends on your feeding routine, budget, and convenience needs.
Frequently asked questions
How does Similac Alimentum help with food allergies?
It uses extensively hydrolyzed proteins that are broken down into small peptides, which are less likely to be recognized as allergens by a baby's immune system. This reduces colic symptoms caused by protein sensitivities or food allergies.
Can I use Similac Alimentum for a baby with lactose intolerance?
Similac Alimentum is not specifically labeled as lactose-free. It is designed for protein sensitivities, not lactose intolerance. If your baby has lactose intolerance, consult your pediatrician for a suitable formula. Always confirm the specific condition with your doctor before switching formulas.
How do I prepare Similac Alimentum powder safely?
Wash hands and surfaces. Boil water and let it cool to room temperature (about 70°F/21°C). Add water to the bottle first, then add the powder scoop. Shake well and feed within 1 hour. Discard any unused formula after 1 hour at room temperature. Refrigerate prepared bottles and use within 24 hours. Never microwave formula; it creates hot spots that can burn your baby.
How long does an opened can of Similac Alimentum powder last?
Once opened, use the powder within 1 month. Store the can in a cool, dry place with the lid tightly closed. Do not refrigerate the powder as moisture can cause clumping. Write the date you opened the can on the label to track freshness.
