Vitamins are essential micronutrients the body needs in small amounts to function normally, with different vitamins supporting different processes throughout the body.

This depends on your diet, age, lifestyle and individual nutritional needs. A multivitamin can provide broad nutritional support, while individual vitamins can target specific requirements.

A multivitamin combines multiple essential vitamins and often minerals into one convenient supplement designed to complement your daily diet.

Many multivitamins are designed for daily use, but they should complement rather than replace a varied, balanced diet. Always follow the recommended dosage.

Vitamin D contributes to normal immune function, healthy bones and teeth, normal muscle function and normal calcium absorption.

UK guidance recommends that adults and children over four consider a daily 10 microgram vitamin D supplement during autumn and winter, when sunlight is less sufficient for vitamin D production.

Vitamin C contributes to normal immune function, collagen formation and protection of cells from oxidative stress, while also helping reduce tiredness and fatigue.

B vitamins perform several important functions, with many contributing to normal energy metabolism, nervous system function and the reduction of tiredness and fatigue.

Often, yes, but different products can contain the same vitamins and minerals, so check labels carefully to avoid unnecessarily high combined intakes.

No. Vitamin supplements are designed to supplement your diet, not replace it. A varied and balanced diet remains the foundation of good nutrition.
