B12, B1, B2, B5 and some others
bacteria in the intestines
Bacteria in the large intestine can produce important vitamins for the body. For example, some bacteria produce vitamin K from eating fiber. Some bacteria also produce vitamin D.
Vitamin K is a fat-soluble vitamin produced by bacteria in the GI tract. In needs fat (lipids) to be absorbed by the intestines. You do not need to add extra Vitamin K.
vitamin D is produced by the body from exposure to sunlight and vitamin k is produces by the body in the large intestine by bacteria wiki on! :)
We don't get any special proteins from microorganisms. What we get is vitamin K which is produced from a bacteria called E.coli and which lives in our intestine.
Vitamin K is made from bacteria from the intestine.
Vitamin "K"
Vitamin D
There are a selection of vitamins that are in the Vitamin K group. These are known as K1-K5. Vitamin K1 is not produced by the body but is absorbed from foods such as green leafy vegetables (spinach, cabbage, broccoli) and some fruits such as avocado and kiwi fruit. Vitamin K2 is produced by bacteria in the large intestine. Vitamins K3-K5 are synthetic and are not generally used for human consumption.

Shortest answer, no. Vitamin K is a vitamin.
There are 4 forms of vitamin D, and the important ones are synthesized by the reaction between UV rays and cholesterol in our skin. Vitamin K2 is synthesized in the guts by bacteria. Vitamin B3 Niacin is synthesized in small amounts by gut bacteria. Vitamin B5 Pantothenic Acid is synthesized in small amounts by gut bacteria. Vitamin B7 Biotin is synthesized in small amounts by gut bacteria. Vitamin B9 Folic Acid is synthesized in small amounts by gut bacteria. Vitamin B12 is synthesized in the guts by bacteria.
