Sustained release of a composition in vivo to increase athlete performance by providing adequate timed release of nutrients and increased absorption. An aqueous suspension comprising (a) one or more biologically active substances; and (b) one or more hydrogel particles encapsulating one or more biologically active substances (a). The one or more hydrogel particles have (i) a diameter of 1 nm to 1000 μm; (ii) one or more compounds that are non-toxic, covalently cross-linked, and time-controlled and persistent in vivo And (iii) is pH responsive, wherein the one or more compounds of the hydrogel particles have a pH of 1-3. And (iv) the suspension, wherein the one or more compounds of the hydrogel particles have a lower critical solution temperature in an aqueous solution. [Selection] Figure 1 |
