Prebiotic supplements still represent a small category; they were at $96.1 million in annual sales in 2018, compared with probiotic supplements at $2 billion. However, prebiotics represent a huge growth opportunity, with three consecutive years of doubling sales and growth of more than 120 percent. Synbiotic supplements, formulas containing a blend of prebiotics and probiotics, had estimated annual sales of $658 million in 2018, representing a more established category with slower, but still notable, growth of 16.2 percent. With slowing growth of probiotics in 2017 and 2018, prebiotic and synbiotic supplements certainly represent the current opportunity in gut health.
Nutrition Business Journal just released these and other statistics in its 2019 Supplement Business Report, the go-to source for data and insight within the dietary supplement industry.
