B vitamins are also vulnerable to high temperatures. When meat is cooked and its fluids are lost, it is possible that up to sixty percent of the thiamine, niacin, and other B vitamins will be lost. But if you drink the liquid that contains these juices, you won’t lose any of the minerals, and you’ll keep between 70 and 90 percent of the B vitamins (6).

Which vitamin is completely destroyed by cooking?

Because vitamin C is a water-soluble and temperature-sensitive vitamin, it is rapidly damaged during cooking. It has been discovered that high temperatures and extended cooking durations produce particularly significant losses of vitamin C [12].

Does vitamin B12 get destroyed by cooking?

Easily ruined by the cooking process in a microwave: Vitamin B12. Easily misplaced in the liquid used in cooking: Vitamins that may be dissolved in water include those in the B vitamin family (including folate), as well as vitamin C.

There are no natural plant sources of vitamin B12, and animal products contain only trace levels of the nutrient when it is present at all.

How do you absorb B12 better?

Vitamin B12 is converted into its free form by hydrochloric acid and enzymes that are produced in the stomach. After then, the vitamin B12 will mix with something called an intrinsic factor, which is a protein, so that it may be absorbed farther on in the small intestine. Since dietary supplements and meals that have been fortified include B12 in its free form, it is possible that these substances are easier to absorb.
