Understanding Nutritional Supplements — Your GP's Guide
Nutritional supplements fill gaps in the diet and support specific health needs. Common examples include vitamin D, folic acid, iron, B12, omega-3 and calcium. Most people can get what they need from a balanced diet, but some benefit from supplementation.

Navigating Nutritional Supplements: A Doctor's Perspective on Vitamin D and Calcium
Overview
NHS guidance recommends daily vitamin D (10 micrograms) for all UK adults, especially October to March. Folic acid is advised for women planning pregnancy, and B12 or iron for those with diagnosed deficiency.
When to seek medical advice
See a GP for unexplained tiredness, hair loss, tingling, mood changes or poor concentration before buying a cocktail of supplements.
Available treatments
Supplements are available as tablets, capsules, liquids, gummies and effervescent forms. Some prescription-strength vitamins such as B12 injections, iron infusions and high-dose vitamin D are available when needed.
What to expect
Most supplements take weeks to months to correct deficiencies. Blood tests confirm progress and avoid unnecessary long-term use.
Self-care
Prioritise a varied diet, get safe sun exposure in summer, limit ultra-processed foods and only supplement when advised or following NHS recommendations.
How Prescriptsy compares providers
We compare available options using verifiable attributes, not clinical suitability. Only a doctor working for the chosen provider can make that assessment.
We consider indicative price and availability, the consultation and prescription route, and public information about the provider and its licences.
Prescriptsy may receive a fee after a referral. This does not change the user's price or determine the medical information we publish.
Prices, stock and terms can change. Always verify final details with the provider; display order is not medical advice or a treatment recommendation.
