Made in the skin on exposure to sunlight, and present in very few foods. This is the vitamin an indoor working life most reliably erodes.
Needed for the absorption of calcium and phosphorus, and therefore for normal bones and teeth. It also has a role in normal muscle function and immune function.

KABO does not publish a milligram-by-milligram breakdown of every micronutrient, so this page describes what the ingredient is and what it is needed for rather than how much of it a serving contains. The full ingredient list is printed on every pack and set out at kabo.co.in/pages/ingredients. This is general nutrition information, not medical advice — if you are pregnant, managing a medical condition or taking medication, talk to your doctor before changing what you take.
