Welcome to Vita Katalyst. The terms “we”, “us” and “our” refer to Vita Katalyst, a brand operated by Radissance Ltd. Vita Katalyst operates this website, including all educational content, articles, scientific research, and resources hosted on the primary domain, as well as our online store platform operated on the subdomain shop.vitakatalyst.com, including all related information, features, tools, products, and services in order to provide you, the customer, with an integrated educational and shopping experience (the “Services”). Our e-commerce infrastructure is powered by Shopify, which enables us to provide the transaction and checkout portions of the Services to you.
The below terms and conditions, together with any policies referenced herein (these “Terms of Service” or “Terms”) describe your rights and responsibilities when you use the Services. Please read these Terms of Service carefully, as they include important information about your legal rights, statutory remedies, warranty disclaimers, and limitations of liability.
By visiting, interacting with, browsing, or using any part of our Services, you agree to be bound by these Terms of Service and our Privacy Policy (https://vitakatalyst.com/privacy-policy/). If you do not agree to these Terms of Service or the Privacy Policy, you must not use or access our Services.
By agreeing to these Terms of Service, you represent that you are at least 18 years of age (the age of majority in the United Kingdom), and you have given us your consent to allow any of your minor dependents to use the Services on devices you own, purchase, or manage.
To use certain portions of the Services, including purchasing any of the products we offer, managing subscriptions, or viewing your order history, you must utilize our customer account portal. Customer account creation and management are strictly hosted and handled via our Shopify infrastructure at https://shopify.com/99595714934/account. No user accounts are created or maintained on our primary WordPress site, though direct navigation links to the Shopify account portal may be provided there for your convenience.
To complete a transaction or manage an account, you will be asked to provide certain information, such as your email address, billing, payment, and shipping information. You represent and warrant that all information you provide to our store is correct, current, and complete and that you have all legal rights necessary to provide this information. You are solely responsible for maintaining the security of your account credentials and for all activity occurring under your account. You may not transfer, sell, assign, or license your account to any other person.
We have made every effort to provide an accurate, clear, and scientifically rigorous representation of our products and services in our online stores. However, please note that physical product appearance or packaging details may differ slightly from how they appear on your screen due to the type of device you use to access the store, your screen settings, or its technical configuration.
We do not warrant that the appearance or quality of any products or services purchased by you will meet your personal subjective expectations, though we guarantee they will comply with all description and fitness-for-purpose requirements under UK consumer law.
All descriptions of products are subject to change at any time without notice at our sole discretion. We reserve the right to discontinue any product at any time and may limit the quantities of any products that we offer to any person, geographic region, or jurisdiction, on a case-by-case basis.
When you place an order via shop.vitakatalyst.com, you are making an offer to purchase. Vita Katalyst reserves the right to accept or decline your order for any reason at its sole discretion. Your order is not legally accepted until Vita Katalyst confirms acceptance via a dispatch confirmation email. We must receive and successfully process your payment before your order is accepted.
Please review your order carefully before submitting. Because our processing systems are designed for swift fulfillment, Vita Katalyst may be unable to accommodate cancellation requests after an order is submitted. In the event that we do not accept, make a change to, or cancel an order prior to dispatch, we will attempt to notify you by contacting the email, billing address, and/or phone number provided at the time the order was made.
Your purchases are subject to return or exchange solely in accordance with our Returns & Refund Policy (https://vitakatalyst.com/returns-refund-policy/). You represent and warrant that your purchases are for your own personal or household use and not for commercial resale, distribution, or export.
Prices, discounts, and promotions are subject to change without notice. The price charged for a product will be the price in effect at the time the order is placed and will be set out in your order confirmation email. Unless otherwise expressly stated, posted prices include UK VAT where applicable but do not include shipping and handling charges, which are calculated at checkout.
We may offer, from time to time, promotions on the Services that may affect pricing and that are governed by terms and conditions separate from these Terms. If there is a conflict between the terms for a promotion and these Terms, the promotion terms will govern.
You agree to provide current, complete, and accurate purchase, payment, and account information for all purchases made at our store. You agree to promptly update your account and other information, including your email address, credit card numbers, and expiration dates, so that we can complete your transactions and contact you as needed.
You represent and warrant that (i) the credit card or payment information you provide is true, correct, and complete, (ii) you are duly authorized to use such payment method for the purchase, (iii) charges incurred by you will be honored by your credit card or payment company, and (iv) you will pay charges incurred by you at the posted prices, including shipping and handling charges and all applicable taxes.
All delivery and shipping processes are executed in accordance with our Shipping Policy (https://vitakatalyst.com/shipping-policy/). Standard UK delivery is fulfilled through trusted courier partners, including Royal Mail and Evri. We currently ship throughout the United Kingdom and do not accept orders or ship outside the United Kingdom.
While we strive to meet estimated delivery times (typically 1–3 business days after dispatch), delivery times are estimates only and are not guaranteed. Vita Katalyst is not liable for shipping and delivery delays caused by shipping carriers, independent courier disruptions, adverse weather conditions, periods of high demand, or any events outside our reasonable control.
Once your order has been handed to the carrier, risk of loss or damage passes to you, without prejudice to your statutory rights regarding faulty or damaged goods as outlined in our legal policies. Customers are entirely responsible for providing accurate delivery information at checkout; we cannot accept responsibility for delays, losses, or additional charges resulting from incorrect or incomplete shipping details.
Our Services—including but not limited to all trademarks, brands, corporate names, long-form articles, scientific explanations, educational breakdowns, text, displays, layouts, bespoke illustrations, Da Vinci-style sketches, color systems, graphics, video, audio, and the design, selection, and arrangement thereof—are owned exclusively by Vita Katalyst, its affiliates, or its licensors and are protected by United Kingdom and international copyright, trademark, patent, and other intellectual property or proprietary rights laws.
These Terms permit you to use the Services for your personal, non-commercial use only. You must not reproduce, distribute, modify, create derivative works of, publicly display, publicly perform, republish, download, scrape, harvest, store, or transmit any of the material on the Services without our prior written consent.
Specifically, you are strictly prohibited from using any of our editorial, research, or scientific text to train machine learning models, text generation systems, large language models, or related artificial intelligence tools. Except as explicitly provided herein, nothing in these Terms grants or shall be construed as granting a license or any other rights to you under any copyright, trademark, patent, or other intellectual property of Vita Katalyst, Radissance Ltd, Shopify, or any third party. Vita Katalyst’s names, logos, product and service names, designs, and slogans are trademarks of Vita Katalyst or its affiliates or licensors. Shopify’s name and logo are trademarks of Shopify. All rights not expressly granted herein are reserved.
You may be provided with access to third-party tools as part of the Services (such as subscription management systems or third-party tracking portals), which we neither monitor nor have any direct control over.
You acknowledge and agree that we provide access to such tools “as is” and “as available” without any warranties, representations, or conditions of any kind and without any endorsement. We shall have no liability whatsoever arising from or relating to your use of optional third-party tools. Any use by you of the optional tools offered through the site is entirely at your own risk and discretion, and you should ensure that you are familiar with and approve of the terms on which tools are provided by the relevant third-party provider(s).
The Services may contain materials and hyperlinks to websites provided or operated by third parties, including embedded third-party functionality. We are not responsible for examining or evaluating the content or accuracy of any third-party materials or websites you choose to access. If you decide to leave the Services to access third-party sites, you do so entirely at your own risk.
We are not liable for any harm or damages related to your access of any third-party websites, or your purchase or use of any products, services, resources, or content on any third-party websites. Please review carefully the third-party’s policies and practices and make sure you understand them before you engage in any transaction.
Vita Katalyst is powered by Shopify, which enables us to provide the e-commerce transaction elements of the Services to you. However, any sales, contracts, and purchases you make in our store are made directly with Vita Katalyst (Radissance Ltd). By using the Services, you acknowledge and agree that Shopify is not responsible for any aspect of any sales between you and Vita Katalyst, including any injury, damage, or loss resulting from purchased products or services. You hereby expressly release Shopify and its affiliates from all claims, damages, and liabilities arising from or related to your purchases and transactions with Vita Katalyst.
All personal information we collect through the Services is subject to our Privacy Policy, which can be viewed at https://vitakatalyst.com/privacy-policy/. Because the transactional elements of the Services are hosted by Shopify, certain personal information may also be subject to Shopify’s core Privacy Policy. By using the Services, you acknowledge that you have read and understood these privacy policies. Information you submit to the Services will be transmitted to and shared with Shopify, as well as trusted third-party service providers, in order to complete processing, shipping, and subscription management.
If you submit, upload, post, email, or otherwise transmit any ideas, suggestions, feedback, reviews, product ratings, proposals, plans, or other content (collectively, “Feedback”), you grant us a perpetual, worldwide, sublicensable, royalty-free license to use, reproduce, modify, publish, distribute, and display such Feedback in any medium for any purpose, including for marketing and commercial use.
We are and shall be under no obligation (1) to maintain your Feedback in confidence; (2) to pay compensation for your Feedback; or (3) to respond to your Feedback. We may, but have no obligation to, monitor, edit, or remove Feedback that we determine in our sole discretion to be unlawful, offensive, threatening, libelous, defamatory, obscene, or otherwise objectionable or that violates any party’s intellectual property or these Terms of Service.
You agree that your Feedback will not violate any right of any third party, including copyright, trademark, privacy, personality, or other personal or proprietary right. You further agree that your Feedback will not contain libelous or otherwise unlawful, abusive, or obscene material, or contain any computer virus or other malware that could in any way affect the operation of the Services. You may not use a false email address, pretend to be someone other than yourself, or otherwise mislead us or third parties as to the origin of any Feedback. You are solely responsible for any Feedback you make and its accuracy.
Occasionally there may be information on or in the Services that contains typographical errors, inaccuracies, or omissions that may relate to product descriptions, pricing, promotions, offers, product shipping charges, transit times, and stock availability. We reserve the right to correct any errors, inaccuracies, or omissions, and to change or update information or cancel orders if any information is inaccurate at any time without prior notice (including after you have submitted your order, in which case a full refund will be issued).
You may access and use the Services for lawful purposes only. You may not access or use the Services, directly or indirectly:
(a) for any unlawful or malicious purpose;
(b) to violate any local, national, or international regulations, rules, or laws;
(c) to infringe upon or violate our intellectual property rights or the intellectual property rights of others;
(d) to harass, abuse, insult, harm, defame, slander, disparage, intimidate, or discriminate against any of our employees, directors, partners, or any other person;
(e) to transmit false or misleading information;
(f) to transmit, or procure the sending of, any unsolicited advertising or promotional material, including “junk mail,” “spam,” or any other similar solicitation;
(g) to impersonate or attempt to impersonate Vita Katalyst, a Vita Katalyst employee, or any other person or entity; or
(h) to engage in any conduct that restricts or inhibits anyone’s use or enjoyment of the Services, or which may harm Vita Katalyst, Shopify, or users of the Services, or expose them to liability.
In addition, you agree not to:

(d) spam, phish, pharm, or pretext the services;

(f) interfere with, bypass, or circumvent the security or authorization features, robot exclusion headers, or other firewalls we employ to restrict access to the Services.
We reserve the right to suspend, disable, or terminate your account and block your access to the domain at any time, without notice, if we determine that you have violated any part of these Terms.
14.1 This section (“Agent Terms”) applies if you use, allow, enable, or cause the deployment of an Agent to access, use, or interact with any portion of the Services. “Agent” means any software, script, bot, crawler, or service that takes autonomous or semi-autonomous action on behalf of, or at the instruction of, any person or entity and that can be executed without direct, real-time human supervision.
14.2 No Agent may access, use, or interact with the Services unless, at all times, it identifies itself openly and operates in strict accordance with the technical requirements in Section 14.4 below. In addition, no Agent may access, use, or interact with the Services if we have explicitly requested via robot.txt protocols, headers, or direct notices that the Agent refrain from doing so.
14.3 We may limit, including by technical firewall measures, IP blocks, or API rate-limiting, whether and how any Agent accesses, uses, and interacts with the Services.
14.4 Agents must: (i) in all HTTP/HTTPS requests, explicitly identify that the request originates from an Agent and disclose the true name and operator of the Agent by including the following string in the request’s user-agent field: “Agent/[agent name]”; (ii) not conceal or obfuscate that any access, use, or interactions are from an Agent, such as by mimicking human browsing behavior, rotating IPs fraudulently, or completing or circumventing CAPTCHAs or measures intended to distinguish computer use from humans; (iii) respond truthfully to any technical question or prompt seeking to determine if interactions are coming from a human or a computer; and (iv) not circumvent or otherwise avoid any measure intended to block, limit, modify, or control whether and how Agents access, use, or interact with the Services.
We may terminate this agreement or your access to the Services (or any part thereof) in our sole discretion at any time without notice, and you will remain liable for all amounts due up to and including the date of termination.
The following sections will continue to apply following any termination: Intellectual Property, Feedback and Reviews, Termination, Disclaimer of Warranties, Limitation of Liability, Indemnification, Severability, Waiver; Entire Agreement, Assignment, Governing Law & Jurisdiction, Privacy Policy, and any other provisions that by their nature should survive termination.

EXCEPT AS EXPRESSLY STATED BY VITA KATALYST, THE SERVICES AND ALL PRODUCTS OFFERED AND DELIVERED TO YOU THROUGH THE SERVICES ARE PROVIDED ‘AS IS’ AND ‘AS AVAILABLE’ FOR YOUR USE, WITHOUT ANY REPRESENTATION, WARRANTIES, OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING ALL IMPLIED WARRANTIES OR CONDITIONS OF MERCHANTABILITY, MERCHANTABLE QUALITY, FITNESS FOR A PARTICULAR PURPOSE, DURABILITY, TITLE, AND NON-INFRINGEMENT, TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW. WE DO NOT GUARANTEE, REPRESENT, OR WARRANT THAT YOUR USE OF OUR SERVICES WILL BE UNINTERRUPTED, TIMELY, SECURE, OR ERROR-FREE.
Nothing in these Terms of Service shall limit or exclude our liability for death or personal injury caused by our negligence, fraud or fraudulent misrepresentation, or any other liability that cannot be excluded or limited by the laws of England and Wales.
Subject to the paragraph above, in no case shall Vita Katalyst, our parent company, Radissance Ltd, our partners, directors, officers, employees, affiliates, agents, contractors, service providers, or licensors, or those of Shopify and its affiliates, be liable for any injury, loss, claim, or any direct, indirect, incidental, punitive, special, or consequential damages of any kind—including, without limitation, lost profits, lost revenue, lost savings, loss of data, replacement costs, or any similar damages, whether based in contract, tort (including negligence), strict liability or otherwise—arising from your use of any of the Services or any products procured using the Services, or for any other claim related in any way to your use of the Services or any product, including, but not limited to, any errors or omissions in any content, or any loss or damage of any kind incurred as a result of the use of the Services or any content (or product) posted, transmitted, or otherwise made available via the Services, even if advised of their possibility.
You agree to indemnify, defend and hold harmless Vita Katalyst, Radissance Ltd, Shopify, and our affiliates, partners, officers, directors, employees, agents, contractors, licensors, and service providers from any losses, damages, liabilities, or claims, including reasonable legal fees, payable to any third party due to or arising out of (1) your material breach of these Terms of Service or the documents they incorporate by reference, (2) your violation of any applicable law or the rights of a third party, or (3) your unauthorized or prohibited use of the Services.
We will notify you of any indemnifiable claim, provided that a failure to promptly notify will not relieve you of your obligations unless you are materially prejudiced. We may control the defense and settlement of such claim at your expense, including choice of legal counsel, but will not settle any claim requiring non-monetary obligations from you without your explicit consent.
In the event that any provision of these Terms of Service is determined to be unlawful, void, or unenforceable, such provision shall nonetheless be enforceable to the fullest extent permitted by applicable law, and the unenforceable portion shall be deemed to be severed from these Terms of Service. Such determination shall not affect the validity and enforceability of any other remaining provisions.
The failure of us to exercise or enforce any right or provision of these Terms of Service shall not constitute a waiver of such right or provision.

Any ambiguities in the interpretation of these Terms of Service shall not be construed against the drafting party.
You may not delegate, transfer, or assign this Agreement or any of your rights or obligations under these Terms without our prior written consent, and any such attempt will be null and void. We may transfer, assign, or delegate these Terms and our rights and obligations without consent or notice to you.
These Terms of Service, any separate agreements whereby we provide you Services, and any non-contractual obligations arising out of or in connection with them shall be governed by, and construed in accordance with, the laws of England and Wales.
You and Vita Katalyst (Radissance Ltd) hereby agree that the courts of England and Wales shall have exclusive jurisdiction to settle any dispute, controversy, or claim arising out of or in connection with these Terms of Service, including any question regarding their existence, validity, formation, or termination.
