Is Tonic Water Gluten Free?
Tonic water is typically gluten-free as it is primarily made from carbonated water, quinine, and sweeteners. However, it’s always best to check the label or contact the manufacturer to be certain, especially if you have celiac disease or severe gluten sensitivity, as some brands may use additives or flavorings that could potentially contain gluten.

Contains quinine, which historically was used to treat malaria
May help with leg cramps, though evidence is limited
Can be a source of hydration
Often fortified with vitamin C
Lower in calories than many other mixers when used in cocktails
Can be a caffeine-free alternative to other carbonated drinks
May aid in digestion due to its carbonation
Can be used as a mild pain reliever (due to quinine content)
Potentially helps with restless leg syndrome (though more research is needed)
Can be a source of zinc if it contains quinineIt’s important to note that many of these benefits are minor or not conclusively proven. Additionally, tonic water often contains added sugars, so it should be consumed in moderation. Always consult with a healthcare professional for medical advice.
People with quinine sensitivity or allergy
Individuals with a history of quinine-related side effects
Those taking medications that interact with quinine, such as blood thinners or certain antibiotics
People with liver or kidney problems
Individuals with a history of irregular heartbeats
Those with low blood sugar or at risk for hypoglycemia
Pregnant women, especially in the first trimester
People with myasthenia gravis (a neuromuscular disorder)
Individuals with optic neuritis
Those with a history of blackwater fever (a complication of malaria)
People trying to limit their sugar or calorie intake (as many tonic waters contain added sugars)
Individuals with G6PD deficiency (a genetic disorder)
Those with thrombocytopenia (low blood platelet count)
People with tinnitus (ringing in the ears), as quinine may worsen symptomsIt’s always advisable to consult with a healthcare professional if you have any concerns about consuming tonic water, especially if you have pre-existing health conditions or are taking medications.

Explore the Science and Benefits of Tolerase® G.
Relief from Gluten Sensitivity
In the fight against gluten, there is a unique supplement that stands out: Little Helpers anti-gluten pills with 100% Tolerase® G.
This specific enzyme, Tolerase® G, a patented endopeptidase specific for proline, was developed by Royal DSM and has been scientifically proven to be effective in breaking down gluten residues ( 1) . Furthermore, research has shown that Aspergillus niger prolyl endoprotease (AN-PEP), an enzyme closely related to Tolerase® G, can break down gluten so effectively that it barely reaches the duodenum, potentially eliminating gluten toxicity ( 2) ( 3 ) .
On this page we explain why we are so enthusiastic about this supplement, supported by scientific research.

What is Gluten?
Gluten is a group of proteins found primarily in grains such as wheat, barley, and rye. These complex proteins give shape, strength, and texture to bread and other grain products. However, gluten is difficult to digest because it is rich in proline, a non-essential amino acid. This is why about 13% of the world’s population is sensitive to gluten in their diet (1).
How Tolerase® G Works
It is important to note that Tolerase G is designed to have optimal activity in the difficult conditions of the stomach. Its effectiveness on the digestion of gluten in the stomach and duodenum has been scientifically proven ( 1 ).
Studies have shown that a newly identified prolyl endoprotease derived from Aspergillus niger can effectively break down gluten proteins. This enzyme works optimally at a pH of 4–5, remains stable at pH 2, and is completely resistant to digestion by pepsin ( 2 ). Furthermore, research has shown that Aspergillus niger prolyl endoprotease (AN-PEP) accelerates the breakdown of gluten in the stomach so much that very little gluten reaches the duodenum ( 3 ). This suggests that co-administration of AN-PEP with a meal containing gluten could potentially eliminate gluten toxicity, allowing people to (occasionally) abandon their strict gluten-free diet ( 3 ).
