Additionally, the use of 'natural flavors' lacks transparency and may indicate further processing, impacting the overall healthiness of the product.

Key ingredients 5

Carbonate Spring Water
Neutral

Carbonate spring water is a neutral ingredient providing the base for the beverage. It is typically free from additives and provides hydration. No significant processing concerns are associated with this ingredient.

Citric Acid
Neutral

Citric acid is commonly used as a preservative and flavor enhancer in beverages. It is naturally found in citrus fruits but is often industrially produced for use in food products. While it is generally recognized as safe, it can contribute to dental erosion if consumed excessively.

Natural Qunine
Neutral

Natural quinine is used for its bitter flavor and is derived from the bark of the cinchona tree. It is a traditional ingredient in tonic water but should be consumed in moderation due to potential side effects. Quinine is regulated in beverages to ensure safe consumption levels.

Risks

Excessive consumption may lead to side effects such as headaches and nausea.

Pure Fructose
Bad

Pure fructose is a simple sugar that can contribute to excessive sugar intake. It is often used as a sweetener and can lead to health issues like insulin resistance when consumed in large amounts. The processing of fructose isolates it from its natural sources, reducing its nutritional value.

Risks

Excessive consumption of fructose may lead to metabolic issues such as insulin resistance and increased triglyceride levels.

Natural Flavors
Bad

Natural flavors are a catch-all term for flavoring agents derived from natural sources but can be highly processed. The lack of transparency in their composition can be concerning for consumers seeking clean labels. They do not provide nutritional benefits and may mask the presence of less desirable ingredients.

Risks

Potential allergenicity and lack of transparency in ingredient sourcing.
