Product Description
Product Description
CalGly is built around calcium glycerophosphate — a pre-meal acid buffer that may help reduce the acid content of the foods and drinks you love, so coffee, citrus, tomatoes and a glass of wine can stay part of your day. Each vegan capsule pairs it with 40 mg of organic, anthraquinone-free aloe vera (with SSAV), the same gentle aloe we are known for.
It is made with the same active ingredient many people used in Prelief in the US, and a familiar part of many IC-friendly diets — now produced for Europe, labelled to European standards and dispatched from within the EU.
All Desert Harvest supplements are gluten-free, free from fillers and artificial ingredients, and made to Good Manufacturing Practice (GMP) standards.
Ingredients: Each capsule contains 230 mg of calcium glycerophosphate (providing 44 mg of calcium) and 40 mg of organic aloe vera powder, with a trace of silicon dioxide as an anti-caking agent. Suitable for vegans.
Directions: Take one capsule just before acidic food or drink, to help reduce its acidity. Do not exceed the recommended daily dose.
Food supplement. Do not exceed the recommended daily dose. Food supplements should not be used as a substitute for a varied, balanced diet and a healthy lifestyle. Keep out of reach of children. Consult a healthcare professional before use if you are pregnant, breastfeeding, taking medication or have a medical condition.

Why CalGly
Enjoy more of the foods you love
A pre-meal buffer for the bright, acidic foods many people on an IC-friendly diet otherwise set aside.
Coffee & tea, more at ease
Take one before your morning cup, where it may help reduce the acid in coffee, black tea and other warm favourites.
Citrus & tomatoes, back on the plate
A buffer before oranges, lemons, tomato sauces and dressings — the bright, acidic foods many set aside.
A glass of wine, more relaxed
Wine, fruit juices and vinegars are among the acidic drinks CalGly is made for. Take it just before you pour.
Pocket-sized & meal-ready
Small vegan capsules that travel easily, so a restaurant dinner or a weekend away stays as simple as home.
How it works
How CalGly works
Calcium glycerophosphate is a gentle, mildly alkaline mineral salt. Taken just before something acidic, it acts as a buffer and may help reduce the acid content of what you are about to enjoy. Because you take it in advance, the buffering happens at the table rather than afterwards.
Each vegan capsule pairs 230 mg of calcium glycerophosphate (providing 44 mg of calcium) with 40 mg of organic aloe vera — the same anthraquinone-free Super-Strength Aloe Vera (SSAV) we are known for. It is the same active ingredient many people used in Prelief in the US, and is referenced as a food-acid reducer in IC-friendly dietary resources from the ICA and the IC Network.
For more on the idea behind buffering, see our guide to food acid and the bladder.
