I have bought vitamin D3 drops and have been adding two drops to a plate of food before we eat it. Will it have the same effect if I add it to the whisked eggs and then cook the omelette or is the vitamin denatured by the cooking?

I can't answer the dosage question but a good source of vitamin C is fermented sauerkraut (not vinegar-made). It's my understanding that sea travelers would bring barrels of sauerkraut and eat it daily to prevent scurvy.

The white Japanese varieties have less beta carotene. They're purple on the outside with white flesh. The taste is different, but still good. We can only convert about 10% of that vitamin A into a usable form, by the way.
