Is wisdom element an IQ tax?

No, the word IQ tax is used to describe the high price of some products or services, but the actual effect is difficult to prove or out of proportion to their prices. Wisdom element is a dietary supplement, and its composition and efficacy have been verified by scientific research and clinical practice, which can improve sleep, mood, cognitive ability, language expression ability, memory and attention. The relationship between the price and effect of wisdom element is reasonable, so it does not belong to the category of IQ tax.
