Yes, we are sourcing our ingredients from GMP certified companies and all of our products are manufactured by GMP certified manufacturers.

Every product is independently tested by third-party labs using HPLC and LC-MS. We test for identity (that it is the right ingredient), strength (that each dose contains what the label says), heavy metals, microbial contamination (bioburden) and BPA, a chemical that can leach from plastics. We also run product-specific tests for anything a particular ingredient could carry. For example, we test our Creatine for dicyandiamide, an unwanted by-product of some creatine manufacturing.

Yes. Test results are on each product page. Click the Light Labs widget just below the Add to Cart button to open them. For some products you'll find the reports under the "Lab Reports & Awards" tab instead. If you can't find the results for your product, please get in touch and we'll send them to you.

Once opened, liposomal products need to be refrigerated and consumed within 6 weeks. Before opening you can store them in a cool, dark place but please ensure it is not hot as overheating can affect the integrity of the product. If you have accidentally left the product out of the fridge, don't worry, the product is probably still fine, as long as it hasn't separated - please do put it back in the fridge as soon as possible. Additionally, do not add the Liposomal to hot drinks or mix in blenders as it will also destroy the integrity of the liposomes.

We recommend to store our NMN powder refrigerated to preserve its quality and integrity, especially if you live in a hot country.

We recommend to store our Capsule products in a cool, dark cupboard, away from direct sunlight. However, for our NMN and NAD Max products, we do recommend to keep those refrigerated.

NMN will degrade in hot and humid temperatures. We recommend you store your NMN in a refrigerator or a very cool environment. We ensure that our NMN is stored in a refrigerated/cool environment throughout the manufacturing process and while awaiting shipment at our storage facilities.

We recommend taking NMN Sublingual Powder in the morning on an empty stomach. Place it under your tongue and let it dissolve, then wait at least 30 minutes before eating. Many customers also take it alongside TransResveratrol+ as part of their morning routine.

Most of our supplements work best taken in the morning on an empty stomach, but please check the pack or the product page for each product's own instructions. Berberine+, Spore Probiotic and Omega-3 Krill Oil should be taken with food. Liposomal Spermidine can be taken with or without food.

We always advise to check on the packaging for specific instructions on how and when to take each supplement, or its relevant product page on our website.

For capsule products we recommend to take with a glass of water. If you experience any issues swallowing the capsules whole you can open them up and add to a cold liquid.

Please check the pack or product page for each product's own instructions. Take NMN and NR capsules in the morning on an empty stomach, swallowed with a glass of water. If you find capsules hard to swallow, you can open them and mix the contents into a cold drink.

For NMN Sublingual Powder, take it in the morning on an empty stomach: place it under your tongue, let it dissolve, then wait at least 30 minutes before eating. If you find the taste too strong, mix it into cold water, yoghurt or a smoothie. Add it after blending and stir it in with a spoon. Please don't add it to hot drinks or hot food.

Both contain the same 99% pure Uthever® NMN. The difference is how you take it: the powder is placed under the tongue to dissolve, and the capsules are swallowed with water. Choose whichever suits your routine.

Both versions of our product work fine as per the feedback from our customers. There are minor differences between the capsule and liquid version. The liquid version has a higher dosage per serving however one bottle finishes around 5 days earlier (25 days) compared to the capsule version. Whereas the capsule version has a lower dosage per serving but one bottle lasts slightly longer (30 days). We believe that the choice of liquid or capsule version is a personal preference according to the preference of our customers, as there are no major differences between these products.

NMN and NR are both precursors to NAD+, and they reach it by slightly different routes. NMN comes as capsules or a sublingual powder, and NR as capsules. Some customers who didn't get on with NMN have switched to NR. If you're not sure which suits you, please get in touch and we'll help you choose.

Our liquid Liposomal products wrap each nutrient in liposomes, tiny fat-based bubbles designed to help your body absorb it.
