Too many pills and capsules have led to the rise of so-called "pill fatigue," while fortified and functional foods don't quite deliver a functional benefit. That leaves a market opportunity for alternative delivery formats - gummies, powders, beverages and more. It's a rising niche and companies are innovating within this space to meet consumer demand. Already we see the gummies category growing at a clip north of 30 percent this past year. The greens category of nutritional powders grew more than 70 percent last year. What products are meeting this need? We trolled the show floor at Natural Products Expo West and found these eight products to entice consumers.
