The rules, written plainly.

Longitivityis an independently owned and operated business. It is not the manufacturer of the products described here, and it does not speak for them. Nutrilite, Artistry, Satinique, Glister, g&h, XS, eSpring, Atmosphere and iCook are trademarks of their respective owners, used here to identify the products being offered.

Anything written on this site is our own wording, not an official statement from a brand. Where a manufacturer's claim is quoted, it is attributed as such.

A catalog and a reference. There is no checkout, no cart and no payment taken here. Prices are published so you can see them before speaking to anyone, and orders are arranged personally over email once you know what you want.

Sending an enquiry or booking a session places no obligation on you to buy anything.

Prices are in US dollars and are the figures we hold at the time of publishing. They can change, and a product can go out of stock between you reading about it and ordering it. A price on this site is an invitation to enquire, not a binding offer.

Where a discount or promotional price is shown, the dates it runs between are stated alongside it. A few items are listed without a price because no stable figure exists for them; those say so plainly and are quoted on request.

Many pages compare a product against named alternatives sold elsewhere. Those comparisons are researched against public retail listings and are offered in good faith, with two limits worth stating.

• Competitor prices are approximate reference points, not live quotes. They move constantly, and any figure shown may be out of date by the time you read it. Every one of them can be checked in a single search, and we would rather you did.
• Where a competitor is cheaper, the table says so. Nothing is inflated to make our own pricing look better, and no comparison is intended to disparage another product.

Differences described between products reflect published ingredients and specifications. If you spot something inaccurate, tell us at contact@longitivity.com and it will be corrected.

Products bought through us are covered by a satisfaction guarantee, handled directly rather than through a corporate returns line:

• Most products. 100% satisfaction guarantee: return within 6 months for a refund, exchange, or credit.
• Water and air treatment systems. 100% satisfaction guarantee: return within 4 months for a refund, exchange, or credit.

Opened product is covered, which is the point of it. Start a return by emailing contact@longitivity.com within the window; we will confirm whether a refund, exchange or credit suits you best and arrange the return from there. The guarantee covers your satisfaction with the product, not damage from misuse, and applies to products bought through us rather than from another seller.

Ingredient lists and product descriptions on this site are for information. They are not medical advice, and nobody here is a doctor, pharmacist or dietitian. Talk to a qualified professional before starting a supplement, particularly if you are pregnant or breastfeeding, managing a health condition, or taking prescription medication.

Pages describing the business opportunity are informational and are not an offer of employment or a promise of earnings. Any figures shown are accompanied by the published earnings disclosure, which states averages before expenses; most participants earn modestly and results depend on effort, customer base and circumstances that vary by person. Ask us for the current full disclosure before making a decision.

• The writing, photography, comparisons and layout on this site are ours. Read them, share a link, quote a line with credit. Do not republish them wholesale as your own.
• Do not scrape the site, submit forms automatically, or use it to send anyone unsolicited messages.
• Do not use the site in a way that breaks the law or interferes with anyone else using it.

This site is provided as it is. We work hard to keep prices, ingredients and comparisons accurate, and correct mistakes when we find them, but we cannot promise every detail is error-free or current at the moment you read it.

To the extent the law allows, we are not liable for indirect or consequential loss arising from use of this site or reliance on information published here. Nothing in these terms limits any right you have that cannot legally be limited, including under consumer protection law.

These terms are governed by the laws of the State of California, United States.

If they change materially, the date at the top of this page changes with them. Continuing to use the site afterwards means the revised terms apply. Questions go to contact@longitivity.com; see also the privacy policy.
