The invention discloses an antiaging nutrient composition. The antiaging nutrient composition is prepared from nucleotide, lysine, methionine, phenylalanine, threonine, tryptophan, arginine, histidine, glycine, aspartic acid, leucine, isoleucine, valine, serine, glutamine, glutamic acid, proline, tyrosine, cysteine, gamma-aminobutyric acid, taurine, orotic acid, granulesten, egg yolk lecithin, cephalin, alpha-linolenic acid, gamma-linolenic acid, inositol, hydroxytyrosol, vitamin A, vitamin B1, vitamin B2, vitamin B6, vitamin B12, vitamin C, vitamin D, vitamin E, niacin, folic acid, iron, zinc, manganese, copper, selenium, chromium, potassium, calcium, magnesium, choline, L-carnitine, pentose, sodium carbonate and freeze-dried powder of chick embryos hatched for three days. The antiaging nutrient composition has the advantages that neural stem cell proliferation is accelerated, amount of autophagosome is increased and activity of mesenchymal stem cells telomerase is improved.
