Taipei, Feb. 23 (CNA) Taiwan's Food and Drug Administration (FDA) on Thursday unveiled a draft regulation on the use and labeling of a certain type of trans-resveratrol, which states that the substance shall be considered a dietary supplement so long as the daily adults dose does not exceed 150 micrograms.

The draft regulation covers the use and labeling of trans-resveratrol derived from the fermentation of saccharomyces cerevisiae strains, a genetically modified brewers' yeast, and states that the end product must go through a purification process to rid it of genetically modified organisms (GMO) or gene segments.

Liao Chia-ting (廖家鼎), a section chief at the FDA's Food Safety Division, told CNA that naturally occurring trans-resveratrol is commonly found in grapes and red wine and is known for its antioxidant properties.

However, with technological advancements in recent years, the substance is also derived from purified yeasts, Liao said.

The draft regulation was formulated after referring to similar regulations in the European Union and other advanced countries, and would only allow daily consumption of no more than 150 mg by adults, Liao said.

In addition, products containing the substance must be labeled to inform consumers that they could pose health hazards for individuals under the age of 18 or pregnant or lactating women while people on medications should consult with their doctors prior to consumption.

The draft regulation will now undergo a public review period and go into effect in June at the earliest, the FDA said.

Suppliers and vendors found to have used noncompliant trans-resveratrol as an ingredient would face a fine of NT$30,000 to NT$3 million, the FDA added.
