The invention belongs to the technical field of health care products, and particularly relates to a preparation method of a resveratrol nutritional supplement. The method is realized by the following steps: (1) preparing a poly gamma-glutamic acid/chitosan solution; (2) preparing a poly gamma-glutamic acid/chitosan solution and a resveratrol mixed solution; (3) preparing an auxiliary material liquid; (4) mixing the mixed solution with adjuvants, and tabletting. The method for extracting the resveratrol can improve the stability of the resveratrol, improve the extraction efficiency of the resveratrol and reduce the oxidation loss of the resveratrol; the prepared gamma-PGA-CS-resveratrol can resist fatigue and aging, and the resveratrol and the gamma-PGA-CS have a synergistic effect, can play a role in resisting oxidation activity in cells and preventing skin cells from being excessively oxidized, so that the skin cell failure is slowed down, the damaged skin can be repaired, and the failure speed of the skin cells is slowed down. |
