Besides vegetables, how to supplement vitamins?

Eat more fruits rich in vitamins such as apples and oranges, and pay attention to balanced nutrition. You can cultivate the habit of eating vegetables and fruits at ordinary times, and you can't be partial to food for a long time. Vitamins C and E can be supplemented orally, preferably through diet. If you don't eat vegetables, you need to add vitamin B complex and vitamin C, and you can also add multivitamins. Vitamin C should be taken half an hour after meals, and vitamin E should be taken at lunch. Vitamin e is fat-soluble and can only be absorbed when there is oil.
