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.
vitamin d
Vitamin D is synthesized in the skin when a cholesterol precursor is modified by UV radiation from sunlight. This modification is the first step in the activation of vitamin D in the body.
Vitamin D is synthesized in the skin when exposed to sunlight, while vitamin K and some B vitamins (like biotin and vitamin B12) are synthesized by bacteria in the gastrointestinal tract. All other vitamins must be obtained through diet.
Steroid hormones, bile acids, and vitamin D are synthesized from cholesterol in the body.
Vitamin D is not synthesized in the body when a person is confined to a dark cell for a long time. However, it can be obtained through diet or supplements. Vitamin D is primarily synthesized in the skin in response to sunlight exposure, so lack of sunlight would hinder its natural production in the body.
Vitamin D is synthesized when modified Cholesterol molecules. . .
Vitamin D would not be synthesized in a person confined to a dark cell for a long time. Vitamin D is primarily synthesized in the skin in response to sunlight exposure. Without access to sunlight, the body would not be able to produce vitamin D naturally.
vitamin D
Vitamin D, which can be synthesized in the skin through exposure to sunlight, and vitamin K, which is produced by bacteria in the intestines.
cGMP
(Vitamin B / Vitamin D).
if the skin is synthesized by sunlight, vitamin-d is produced.this way the sun helps the body
