How do vitamins like C, D, and A in your supplements support my immune system?

Our Immune Function supplements contain vitamins C, D, and A in amounts that have authorised health benefits. These vitamins help maintain the normal function of your immune system, keeping it strong and ready to defend your body against infections.

Is there a risk of taking too much zinc or selenium with these supplements?

Each supplement provides zinc and selenium in safe amounts compliant with EU and GB health regulations. Taking them as directed ensures you get effective immune support without exceeding recommended daily intakes.

Can I take these immune support supplements alongside other vitamins I already use?

Yes, but it's important to check the total amounts of nutrients like vitamin A, D, and zinc from all your supplements combined. To avoid exceeding safe levels, consider consulting a healthcare professional if you're already taking other vitamin or mineral products.

How long should I take these supplements to notice immune system benefits?

For best results, consistent daily use over several weeks is recommended. Since these products contain nutrients with authorised claims for normal immune function, regular intake helps your body maintain a strong immune response over time.

Are these supplements suitable for vegetarians and free from common allergens?

Our Immune Function collection products are formulated with carefully selected ingredients to support immune health and are suitable for vegetarians. For specific allergen information, please check the product label or description before purchase to ensure it meets your needs.
