Insynergy Labs is a British supplement brand that sells its own range direct from its website. It says it was set up in the UK in 2017, and the business is run by Koutos Ltd, a company registered in England and Wales in June 2017. Its products are made in the UK in facilities the brand describes as GMP and ISO 9001 certified, and it says every batch is third-party tested.
The range runs to around fifty capsule products, sorted into collections for sports nutrition, men's health, women's health, brain, sleep and mood, digestion and thyroid, joints, immunity and hair, and anti-ageing and heart. Alongside single-ingredient supplements such as magnesium glycinate, glycine, turmeric and olive leaf extract, there are multi-ingredient blends with names like ZMX Pro, HMB Pro and Male One. Most bottles cost between about £14 and £30, and the site lists full ingredient details on each product page.
The shop is set up for UK customers and prices are in pounds, though there is also a US dollar storefront. Single bottles carry a £3.99 delivery charge, while orders of two or more bottles ship free. There's a standing multi-buy: buy three supplements and you get a bottle of Magnesium Glycinate free. Unopened bottles can be returned within 14 days, and a 30-day guarantee lets you claim a refund on one opened bottle. Supplements aren't a substitute for a varied diet, so check with a pharmacist or GP if you take medication.
| Delivery | UK delivery (excluding the Channel Islands) costs £3.99 for a single bottle and is free on orders of two or more supplement bottles. The site banner says delivery takes 1-3 days; the shipping policy asks you to allow up to 7-14 working days. |
|---|---|
| Returns | 14 days from delivery to cancel and return unopened, sealed bottles (you pay return postage). A 30-day guarantee also refunds one opened bottle per customer, plus any sealed bottles sent back. Email first for a returns reference. |
| Ways to pay | Visa, Mastercard, American Express, Maestro, PayPal, Apple Pay, Google Pay, Shop Pay and Klarna are shown at checkout. |

Minimum £25; anything under that rolls over to the next quarter.
