Yes. The Frontiers in Psychiatry report that, “for healthy adults, caffeine consumption is relatively safe, but for some vulnerable populations, caffeine consumption could be harmful, including impairments in cardiovascular function, sleep, and substance use.”
The FSSAI states that “there have been many detrimental effects of caffeine. If used in conjunction with alcohol or other substances of dependence, it can have an additional impact on health. Products that have caffeine as an ingredient are usually prohibited from being used as an ingredient in other beverages commonly consumed by children. Pregnant and lactating women are vulnerable groups for whom high consumption of caffeine is not advised. The supply of caffeine from all sources of a normal diet should also be considered while determining the maximum permissible limit.”
Caffeine is not an additive but a chemical with addictive properties. Caffeine up to 200 ppm is added as a flavoring agent but above 200 ppm it is a functional ingredient. The functionality of caffeine at 320 ppm needs to be ascertained along with justification for fixing a cut-off limit at 320ppm.”
Therefore, a safe consumption would be consuming it in the recommended amounts. The recommended amount of caffeine proposed by FSSAI is not less than 145 mg/ liter and more than 300 mg/ liter. The supply of caffeine from all sources of a normal diet should also be considered while determining the maximum permissible limit.
