Daily Vitamin Requirements

Your vitamin needs vary based on age, gender, health status, and lifestyle. It is best to meet these needs through a balanced diet. In certain cases (like pregnancy, illness, or deficiencies), supplements may be required.

Always consult your doctor or pharmacist before starting any vitamin supplement.

Multivitamins and Supplements

Multivitamins combine various vitamins and sometimes minerals in one dose. These can be helpful when:

You have a diagnosed deficiency

Your diet lacks diversity

You have increased nutritional needs (e.g. during pregnancy, illness)

Note: Overuse of supplements, especially fat-soluble ones, can lead to toxicity.

Water-soluble vitamins are best taken with water and on an empty stomach.

Avoid smoking and alcohol, as they deplete vitamin levels.

Store vitamins properly to maintain potency.
