NutritionGo publishes guides to help people in the UK make informed, confident decisions about natural supplements. Health information deserves care, so we hold our content to a clear standard: evidence-led, properly referenced, honestly written, and kept up to date. This page explains exactly how we do that.
Who writes our content
Our guides are researched and written in-house by the NutritionGo editorial team, led by Vanessa Hernandez.
Vanessa Hernandez — Co-founder & Content Lead. Vanessa holds a Level 3 Diploma in Nutrition and is responsible for researching each topic, drafting the guides, and checking every article against authoritative guidance before it is published. She is not a registered healthcare professional, and our content is educational — it is not a substitute for personal medical advice.
How we research and reference
Every factual and health-related statement in our guides is checked against recognised, authoritative sources. Where a guide makes a point about health, nutrition or safety, we trace it back to a credible source rather than opinion. The sources we rely on most are:
- The NHS for general health and safety guidance.
- The GB Nutrition and Health Claims register for which nutrient claims we're permitted to make, and how they must be worded.
- The European Food Safety Authority (EFSA) for the underlying science behind nutrient function.
- Peer-reviewed research indexed on PubMed and reputable scientific journals, cited in-line next to the specific point they support.
We link to our sources so you can read them yourself. We never fabricate a citation, and we check that a source genuinely supports the sentence it sits beside.
How we talk about supplements (compliance)
Food supplements are not medicines, and we are careful never to present them as such. We follow UK advertising rules (ASA/CAP) and the GB Nutrition and Health Claims framework:
- We describe ingredients using authorised nutrient claims — for example how a vitamin or mineral contributes to or helps maintain a normal body function.
- Botanical ingredients that are still "on hold" on the GB register (such as maca, ginseng, moringa, berberine, rhodiola, tiger milk, TUDCA, spirulina, chlorella and nattokinase) are described by their composition and traditional use only — we do not attach a health outcome to them.
- We do not claim any supplement can treat, cure, prevent or diagnose a disease.
- We make clear that food supplements are intended to support a balanced diet, not replace one.
Accuracy, reviews and updates
Health guidance changes, so our guides are living documents. We review and update our content regularly, and each article carries a published and updated date so you can see how current it is. If guidance from a source such as the NHS or EFSA changes, we update the affected guides to match.
Corrections
We want our content to be accurate. If you spot something you believe is wrong or out of date, please tell us at support@nutritiongo.co.uk and we will review it promptly and correct it where needed. For general questions, you can also reach us at hello@nutritiongo.co.uk.
