The doctor questioned the benefits of the popular chlorophyll drink from social networks

Liquid chlorophyll, which has become a popular healthy lifestyle trend, does not yet have a sufficient evidence base for widespread use. This was announced to Izvestia on April 23 by Ekaterina Terentyeva, head of the Invitro Medical Examination department.

"So far, this is more of a marketing trend with some interesting, but preliminary data, rather than a proven "mandatory supplement" for a healthy person," she noted.

According to the expert, existing scientific work on the water—soluble analog of chlorophyll, chlorophyllin, is limited to small samples or experiments on animals and cell lines. They show potential antioxidant and anti-inflammatory effects, but they do not confirm clinical efficacy in healthy people.

The expert stressed that the effect of the supplement on weight loss has not been proven. Although some studies show a decrease in appetite, they were conducted using complex plant extracts and do not provide unambiguous conclusions. A similar situation is observed with effects on the gastrointestinal tract: data are limited by animal experiments, and there is no clinical evidence for the treatment of gastrointestinal diseases.

According to the doctor, the claims about the positive effect of liquid chlorophyll on the skin are also not confirmed. Efficacy is shown only with external use in combination with photodynamic therapy for acne, whereas oral administration does not have sufficient evidence.

The expert added that taking the supplement in moderate doses for a short time is considered relatively safe, but side effects are possible, from digestive disorders to increased skin sensitivity to the sun and allergic reactions.

"There are no long-term (for months or years) qualitative studies on the safety of chlorophyll use. The reviews for doctors emphasize that there is no reliable data for pregnant, lactating, children and adolescents, therefore, the use of chlorophyll supplements in these groups of patients is not recommended without consulting a doctor," Terentyeva concluded.

Dietitian Anastasia Efimova said on March 26 that regular intake of both black and green tea is associated with a lower risk of stroke and cardiovascular mortality. At the same time, excessive consumption of the drink can lead to various negative consequences.
