THERE is too little tongkat ali herb extract in most coffee products to enable such drinks to have any health benefits or extra nutrition as claimed by their manufacturers.
Berita Harian, in its front-page report yesterday, said a Forest Research Institute of Malaysia (FRIM) study on 10 popular tongkat ali coffee brands revealed that seven of them contained only 0.25% to 1.6% of the herbal extract and was not sufficient to benefit one’s health.
