Terms & Conditions

Astra Castra Ltd trading as PARTICULAR (“PARTICULAR”, “we”, “us”) operates the website particular.health and sells personalised food supplement blends to consumers in the United Kingdom. Registered address: 128 City Road, London EC1V 2NX. Contact us at hello@particular.health.

By placing an order you confirm that you are at least 18 years old and agree to these Terms. Please read them carefully before purchasing.

PARTICULAR products are food supplements only. They are not medicines and are not intended to diagnose, treat, cure, or prevent any disease or medical condition. They are not a substitute for a varied, balanced diet and a healthy lifestyle, or for medical advice from a qualified healthcare professional.

All formulas are produced within UK Expert Group on Vitamins and Minerals (EVM) and SACN safe upper level guidelines. Individual ingredient doses are disclosed at the point of formula generation.

When you submit an order, you make an offer to purchase. A contract is formed when we send you an order confirmation email. We reserve the right to decline orders at our discretion (e.g. if a product is unavailable or if we suspect misuse).

Prices are shown in GBP inclusive of any applicable VAT. Food supplements are currently zero-rated for VAT purposes in the UK.

Monthly subscription plans renew automatically each calendar month using the payment method provided at checkout. You authorise PARTICULAR to charge your card on each renewal date.

You may cancel your subscription at any time before the next renewal date from your account at particular.health/account, or by emailing hello@particular.health. Cancellation takes effect at the end of the current billing period; no partial refunds are issued for remaining days in a paid period.

We reserve the right to change subscription prices with 30 days’ notice sent to your registered email address.

You have 14 days from the date of delivery to cancel your order for a full refund without giving any reason, provided the product is unopened and in its original condition. This right does not apply to goods that have been clearly personalised for you once production has commenced.

As your blend is custom-formulated and manufactured specifically for you upon order, the right to cancel under Regulation 28(1)(b) may not apply once production has begun. We will always confirm the status of your order before processing a return request.

To exercise your right to cancel, contact us at hello@particular.health with your order reference.

We currently deliver to UK addresses only. Standard delivery is 3–5 working days from dispatch. We are not responsible for delays caused by third-party couriers or events outside our control.

Risk in goods passes to you upon delivery. Title passes upon full payment.

PARTICULAR’s liability to you shall not exceed the amount you paid for the relevant order. We are not liable for indirect, consequential, or special losses.

Nothing in these Terms limits liability for death or personal injury caused by our negligence, fraud, or any other liability that cannot be excluded by law.

These Terms are governed by the laws of England and Wales. Any disputes shall be subject to the exclusive jurisdiction of the courts of England and Wales.
