Are vitamin supplements really worth take or do u obtain enough natural vitamins from food? i get the cold a lot and would vitamin tabs prevent it?

Yes and no: A person eating a mixed diet gets enough vitamins from diet. A person not eating enough food may need a multivitamin supplement and a person not getting enough sun exposure needs a vitamin d supplement. Vitamins do not prevent or treat colds.

Food and vitamins: To get sufficient vitamins from diet, a person needs balance and variety: meats, eggs, dairy, fruits, veggies, whole grains, nuts, juices. And processed refined foods are not vitamin rich. And, many foods are showing less vitamin content because soils are deficient. So, yes, the best carefully selected regular wide variety diet can provide all vitamins, but is a challenge. Add a high quality VIT.
