The formulas that we have developed at Functional Formularies are created out of whole food ingredients. Our formulas do not contain any added chemicals, preservatives or emulsifiers and as a result, the viscosity can vary.
TEMPERATURE: One of the factors that can change the viscosity of the formula is temperature. The temperature of the formula is integral to their successful use as cooler temperatures will thicken the viscosity of the formula.
It is essential that the formula is at room temperature or a bit warmer in order to ensure that the formula is at its ideal viscosity. If stored in a room that is cool or cold, the formula will thicken making it more difficult to administer. We recommend warming a pouch of formula in a bowl of warm water prior to administration to bring it back to room temperature.
BLENDING: It is best to ensure that the formula is thoroughly shaken or blended prior to use. If mixing the formula with anything, including water, the formula will need to be re-emulsified using a blender or another mechanical method, especially if using a feeding pump. If you choose to add water or other ingredients to the formula, please ensure that the added components are at room temperature or warmer to prevent thickening of the formula.
ADMINISTRATION: All of our formulas were created to be delivered either via a pump, gravity feeding bag or a bolus syringe. When using the various methods, the following tips should be considered.
Our formulas can be used for all tube types including G-tubes, NG tubes, low profile buttons, and J-tubes. Our formulas can be delivered through tubes which are the following tube sizes:
SHELF LIFE: Functional Formularies formulas have a shelf-life of up to 2 years, as long as the product is stored and handled properly at ambient temperatures of 60º to 70º degrees Fahrenheit.
If the product is exposed to higher temperatures (75-100º+) for short periods of time, this will NOT negatively affect the nutritional values. Nutritional values will begin to be affected and have the potential to decrease over time if the products are stored at high heat for extended periods of time (6-12+ months).
If the product is frozen, the nutritional value remains intact. When thawing, the product should be stored at room temperature and allowed to thaw naturally before using. If you need a pouch of formula right away, we recommend that you thaw the unopened pouch by gently placing it in a warm bath of water until the formula is brought up to room temperature.
Weight vs. Volume
Note: Due to temperature changes from manufacturer to use, volume contraction may occur and volume may be slightly less when poured. As long as the entire pouch is utilized, the patient will receive all macro and micronutrients stated on the label.
