Solid, free-flowing, and substantially completely dissolvable preparations with high betalain content are presented. Most typically, the betalain profile of the preparations is near natural and includes betalains in an amount of between 10-40 wt %. As the preparations of the inventive subject matter maintain chemical stability and flowability over extended periods of time, it should be noted that the betalain preparations are now amenable to compounding in small and measured quantities. Furthermore, new biological activities of betalains are shown, and especially include significant induction of SIRT and reduction of serum triglyceride.
