Is it possible to use Nutridrinks containing B vitamins in cancer?

During oncological disease, it is recommended to use Nutridrink Protein, which contains a greater amount of protein and a greater amount of calories. Nutridrink Protein 125 ml can only be used as a dietary supplement – in the number of 2 bottles per day for a minimum of 14 days. Available in flavors: neutral, forest fruits, strawberry, vanilla, mocha, mango-peach, red fruits, tropical fruits with ginger. Nutridrink Protein contains B vitamins, but such amounts should not affect the exacerbation of cancer (these are not shock doses). It should be remembered that Nutridrink preparations should be drunk slowly – one bottle for about 30 minutes – to avoid digestive discomfort. They can also be cooled before drinking.
