Our supplements are manufactured using trusted quality control processes and to recognised industry standards, including Good Manufacturing Practice (GMP) principles where applicable. We are also proud to hold SALSA accreditation, demonstrating that our operational and quality management processes meet rigorous recognised standards for safety, traceability, and quality assurance across the supply chain.

In addition, we are a certified B Corp business, reflecting our commitment to high standards of social and environmental responsibility, transparency, and accountability alongside product quality.

These standards help ensure our customers can shop with confidence knowing quality, compliance, and integrity are central to everything we do.

At Simply Supplements, we're dedicated to providing high-quality vitamins, minerals, and health supplements at the most competitive prices. That's why we offer our Price Match Promise. If you find the same supplement product available for less from another UK retailer, we'll not only match the price but beat it by 10%. Shop with confidence knowing you're getting premium supplements, exceptional value, and the best possible price every time.

All orders placed before 12 noon Monday to Friday will be dispatched the same day and should arrive within their allotted time period. Orders placed after 12 noon, on a weekend or over a bank holiday will be dispatched on the next working day.

Our courier is unable to deliver to PO Box addresses using our free 48-hour tracked delivery service. If you need your goods delivering to a PO Box, please select our 24-hour express delivery service when placing your order.

Please be aware that on rare occasions or during busy periods, delivery times may be slightly longer. Unfortunately, we’re unable to investigate the non-arrival of goods until after 2 working days.

If you wish to cancel or amend your order you must contact our customer care team immediately, by either calling us on 0800 988 0292 or via the online chat service on our website (open from 8 am to 6 pm Monday to Saturday). Please note that all emails are responded to within 48 hours on working days, so your request may not be actioned within enough time before your parcel has been dispatched.

Unfortunately, because we process all orders quickly to ensure fast delivery, we cannot guarantee that we’ll always be able to cancel or amend your order before it has been dispatched.

We do offer a free UK returns policy, so any unwanted, unopened items can be returned to us within 30 days of the delivery date for a no quibble refund or exchange. We recommend that you obtain proof of posting from your local post office upon returning the items.

Refunds will be processed once the returned items are received back into our warehouse. The amount we will refund is the amount paid for the products; delivery costs will not be refunded.
