Fuji Spinning Company's vitamin-infused shirts are made out of a fiber called V-up , which contains the equivalent vitamin content of two lemons (the recommended daily dose) and remains effective after 30 washes.
The emulsified provitamin dissolves upon contact with sebum and sweat on the skin's surface, absorbs into the skin and changes into vitamins inside the body. The company also sells a t-shirt containing vitamin E, in addition to the vitamin C, and plans to market vitamin-enhanced lace underwear.
