Scientifically designed to help children with dysphagia or reflux drink safely

ThickenUp® Junior is an easy-to-use thickener scientifically designed to provide the right level of thickness in a wide variety of liquids. A well-adapted solution to help children from 6 months safely enjoy the experience of original tastes.
IMPORTANT NOTICE: Always consult your healthcare professional before using any thickener for your child. ThickenUp® Junior is a food for special medical purposes, to be used under medical supervision.
ThickenUp® Junior is intended for children aged ≥6 months, and is not suitable for those with a history or risk of necrotizing enterocolitis.
What makes a good thickener?
The right thickener will:
- improve children's oral feeding experience by:
- Reducing the risk of aspiration, laryngeal penetration, gastro-oesophageal reflux disease (GERD) and respiratory infection
- Reducing regurgitation, reflux and vomiting
- Re-establishing adequate feeding and hydration
- Ensuring safe and enjoyable feeding
- Provide consistent and the right level of thickness in a wide variety of liquids
- Provide the right level of thickness adapted to each child's needs
- Preserve the original taste of liquids
Why ThickenUp® Junior is the right thickener
ThickenUp® Junior is the only thickener scientifically designed to reach all IDDSI (International Dysphagia Diet Standardisation Initiative) thickness levels 1 to 4 for young children from 6 months onwards.




IDDSI 1 to 4 - Reaches the right thickness in a wide variety of liquids
ThickenUp® Junior meets IDDSI standards to ensure the right level of thickness is obtained for safe oral feeding in all children with dysphagia or reflux.
The choice of thickening agents is important. Many thickeners are not able to reach required thickness safely in all liquids.

*Locust bean gum is also known as carob gum
ThickenUp® Junior provides the optimal combination of thickening agents
- 10:1 ratio of locust bean gum to xanthan gum
- Provides synergistic effect to achieve desired viscosity
- Ensures great performance in milks
- Ensures tolerance in young children, even at the highest thickness level

Not all thickeners are equally high-performance
Not all thickeners are the same. They behave differently according to fluid properties.
ThickenUp® Junior is the only thickener for this age group scientifically designed to reach all IDDSI thickness levels 1 to 4

- Reaches all IDDSI levels 1 to 4 at different drink temperatures
- Adapted to a wide variety of liquids: water, powdered or liquid formulas, milk, juice, oral nutritional supplements, etc.
- Maintains stability during feeding time (approx. 30 min)

Adapting thickness level to a child's needs
Drink thickness required by each child varies according to their age and extent of dysphagia. The appropriate IDDSI level must therefore be adapted to each child's needs and the right thickness must be easy to reach when following IDDSI standard tests.


ThickenUp® Junior's unique composition preserves the original taste of liquids, which:

- Helps children develop their sense of taste
- Increases drink enjoyment and diversification
- Improves the positive experience of oral feeding and long-term taste and swallowing education
ThickenUp® Junior will help maintain oral feeding in children with dysphagia or reflux to ensure adequate nutrition in a safe and enjoyable way.
ThickenUp® Junior works very well in a wide variety of liquids. Please follow the preparation instructions below for the type of liquid you want to thicken.

The following will guide you on how to use ThickenUp® Junior with water
Mixing Instructions

Liquid first

Add powder
Use the dosage scoop
included in the tin

- Shake vigorously for 30 seconds
- Leave to stand for 5 minutes
- Give one gentle shake and consume
It is recommended to mix by shaking in a bottle for 30 seconds. Shaking is much more effective than stirring with a fork or hand whisk.
Dosing instructions:
The following table indicates the recommended volume of water in mL to reach each IDDSI thickness level. For example, mix 100 mL or mineral water with 2 scoops of ThickenUp® Junior to obtain IDDSI level 2 thickness.
(slightly thick)
1 scoop
(mildly thick)
2 scoops
(moderately thick)
3 scoops
(extremely thick)
5 scoops
or carbonated water
*Hard or soft water?
Hard water has a high calcium content whereas soft water is lower in calcium; therefore hard water produces a thinner mix than soft water for the same amount of ThickenUp® Junior.
- Mineral water: The calcium content of bottled mineral water is usually displayed on the label or can be obtained from the manufacturer. For example. Buxton® has calcium content of 55mg/L and Evlan® of 80mg/L (both hard waters), whereas Nestle®'s Pure Life Spring water contains 27mg/L and Nestle®'s Pure Life Sparkling water contains 11mg/L (both soft waters).
- Tap water: The calcium content of tap water varies in different locations, therefore results with tap water can vary across regions, ThickenUp® Junior dosing will need to be adapted according to the water used.
Therefore, the softer the water (i.e. the lower the calcium content), the higher the volume of water that may be needed to achieve the right thickness (i.e. up to 200mL).
Please be aware that boiling water can reduce its calcium content, thereby making the water softer that before.
Take a look at the video on how to prepare water with ThickenUp® Junior
Care must be taken to achieve the correct thickness according to the water used.
When you use a certain type of water (mineral or tap) for the first time with ThickenUp® Junior, make sure to use the IDDSI thickness test to check whether you have obtained the desired thickness based on dosing instructions. If necessary, you may need to adapt the dosage slightly to meet the desired thickness.

The following will guide you on how to use ThickenUp® Junior in different milk types (e.g. powdered or liquid formulas and cow’s milk)
Mixing Instructions: these apply to all milk types

Liquid first

Add ThickenUp® Junior powder
Use the dosage scoop
included in the tin

- Shake vigorously for 120 seconds
- Leave to stand for 5 minutes
- Give one gentle shake and consume
Whichever milk type you wish to thicken, it is recommended to mix by shaking in a bottle for 120 seconds. Shaking is much more effective than stirring with a fork or hand whisk. Shaking for 120 seconds may seem like quite an effort, but the smooth consistency of the resulting mixture is worth the effort.
Dosing instructions:
1. Breast milk
If you are breastfeeding beyond 6 months, ThickenUp® Junior has been shown to perform well in breast milk. However, please first consult your healthcare professional and note that you will need to test and adapt the dosing to your breast milk, because of the wide variations in the nutritional composition of breast milk among mothers. Remember as well that your breast milk composition will vary depending on the stage of lactation and your diet.
Please use the IDDSI thickness test to help you obtain the desired thickness of your breast milk.
To learn more about the IDDSI standards please visit the IDDSI website: www.iddsi.org
2. Powdered and liquid formulas
ThickenUp® Junior is suitable for thickening specialized formulas (eg: amino acid or peptide based) for children above 6 months with gastrointestinal tract impairment, e.g. dysphagia, gastro-oesophageal reflux.
To thicken formula, the recommended method is to prepare the formula first according to the manufacturer’s instructions, then allow the liquid to cool to serving temperature (37°C). Once this step is achieved, use ThickenUp® Junior to thicken the liquid. This helps ensure thickness consistency across different formulas.
The following table indicates the average volume of prepared formulas recommended to reach IDDSI thickness levels 1 to 3. For example, to obtain level 1 thickness, first prepare your powdered formula (90ml of cooled boiled water + required amount of formula powder), then add 1 scoop of ThickenUp® Junior.
(slightly thick)
1 scoop
(mildly thick)
2 scoops
(moderately thick)
3 scoops
(extremely thick)
5 scoops
(powdered or ready-to-feed)*
*These values represent the average dosing obtained from testing with specialized formulas (eg: peptide based) and must be adapted according to the actual formula used.
**IDDSI level 4 can be reached but is not suitable for bottle feeding.
