General information to help you read labels and make informed choices. For personal medical advice, speak to a qualified healthcare professional.
How should I choose a supplement?
Read the ingredient list, amount per daily serving, directions and warnings for the specific product. Ask a pharmacist or healthcare professional about suitability if you take medicines, are pregnant or breastfeeding, or have a health condition.
Are all Sterling Nutrition products vegan?
Suitability varies by product, including the capsule or softgel material. Check the specific listing and pack label for vegan or vegetarian suitability and allergens.
Does organic certification apply to every product?
No. An organic designation is specific to a product and its certification scope. Check the individual listing rather than assuming the whole range is organic.
How can I check manufacturing and quality information?
Manufacturing standards and certificates apply to particular facilities, products and scopes. Email customer services with the product name if you need supporting information. See our Quality and Ingredients page.
Where can I find ingredients and allergens?
Use the full ingredients and allergen information for the exact product and variant. Formulations differ, so information about one product should not be applied to another. Contact us if the information you need is unclear before ordering.
Are natural ingredients always safe?
No. Natural ingredients can still cause side effects or interact with medicines. Follow the label and obtain individual advice when needed.
What are vitamins and minerals?
They are nutrients needed in small amounts. A varied diet provides many of them, though some people may need supplements. The NHS vitamins and minerals guide explains individual nutrients and precautions.
What do the quantities and percentages on a label mean?
Check the amount per recommended daily serving and the units used. A percentage reference value helps compare nutrient amounts; it is not a personalised dose recommendation. Extract weight and raw-ingredient equivalent are different quantities.
Does a larger dose mean a better product?
No. Compare the whole formulation and directions. Do not exceed the recommended amount or combine overlapping products without checking suitability.
Can supplements replace a balanced diet or prescribed treatment?
Food supplements are not a replacement for a varied diet or prescribed treatment. Avoid treating a supplement as a cure for a medical condition.
Can supplements treat stress, depression or anxiety?
Do not use supplement marketing to diagnose or treat a mental health condition. Speak to a qualified healthcare professional if you need support. See the NHS mental health information.
What should I do if I feel unwell after taking a supplement?
Stop taking the product and seek advice from a pharmacist or healthcare professional. For severe symptoms, seek urgent medical help. Keep the packaging and ingredient list available, and tell us which product and batch were involved.
Do age, body size or where I live determine my supplement dose?
Those factors alone do not establish that you need a supplement or a higher dose. Follow product age restrictions and ask a qualified professional for individual advice where needed.
How should I store supplements?
Follow the storage instructions on the exact product label, including any refrigeration requirement. Do not assume storage advice for a different brand applies. Keep supplements out of reach of children.
How should I dispose of packaging?
Check the material and recycling instructions on each component and the guidance from your local authority. Recycling arrangements vary; not every pack component can go into every household recycling bin.
Where can I find delivery and returns information?
Our Delivery and Returns page has the current charges, estimated delivery times and returns conditions.
