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.

Yes. Our NMN is 99% pure Uthever® NMN and is third-party tested for purity, stability and heavy metals. You can view the latest test results on the NMN product pages: click the Light Labs widget just below the Add to Cart button.

Yes. Our NR is third-party tested for purity. You can view the latest test results on the NR Capsules product page: click the Light Labs widget just below the Add to Cart button.

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.

Our capsules, softgels and NMN Sublingual Powder won't break a fast. Products that contain calories could, including our liquid Liposomal products, AM: Sunrise Blend, PM: Sleep Dust, V14, Collagen Jelly, Micronised Creatine Chews and Mood Food Mixers.

All of our products are vegan, except Omega-3 Krill Oil and Vitamin D3 + K2.

Yes, our full range of products is gluten-free.

We ship to various destinations worldwide, but there are some exceptions such as South America, Africa, The Caribbean, Canary Islands (we do ship to mainland Spain), China and Hong Kong.

Please note that we are not responsible for covering any applicable import taxes or duties for orders outside the UK and EU. Youth & Earth will not take responsibility to pay custom taxes. 

Yes, you can set up a monthly subscription for any of our products at a discounted rate.

Once you go on the specific product page of the product you wish to set up a subscription for, make sure to select the 'Subscribe and Save' option, instead of the 'One-time Purchase' option. Then, add the product to your cart. Once you have done this for all the individual products you wish to have a subscription for, you can go to your basket and proceed with your order. Please note, if you wish for any subscriptions to arrive at a different time of the month, you will have to set up separate subscriptions by placing separate orders. Alternatively, once you set up a subscription for a few products under the same order, all of these products will then arrive together monthly.

You have full control over your subscription and can edit, pause, or cancel it anytime. If you have too much product, you can skip an order while keeping your subscription active. You can also change your next order date, remove or add products from/to your subscription.

You can manage all of this through your online account. Here’s how:

• Log into your account on our website using the email address you used to place your orders.
• If you’re having trouble logging in, check that you’ve actually created an account - having a subscription doesn’t automatically mean you have an account.
• If you try to reset your password but don’t receive an email (even in your junk/spam folder), you likely don’t have an account yet.
• Create an account using the same email linked to your orders, and you’ll then be able to manage your subscription and see all of your past orders.

If you need any help making changes or need any assistance accessing your account, feel free to reach out to us at support@youthandearth.com—we’re always happy to assist!

Setting up a subscription takes the hassle out of reordering your supplements each time - so you never run out! Plus, you’ll save 20% or 25% (depending on the product) with a permanent discount, making it a more cost-effective way to maintain your routine.

Consistency is key when it comes to supplements - having a regular monthly delivery ensures the ingredients build up in your system, allowing you to experience the full, long-term benefits over time.

If your discount code isn’t working, it may be because discount codes cannot be applied to subscription products, as they already come with a built-in discount. However, you can still use your code by following these steps:

1. Remove the subscription product from your basket.
2. Re-add the product, but select the one-time purchase option instead of subscription.
3. Enter your discount code at checkout - it should now apply successfully!

If your code still isn’t working, double-check that:

✔ It hasn’t expired.
✔ You are not trying to use it alongside another discount.
✔ There are no typos or extra spaces when entering the code.
✔ The code is valid for the specific product you’re purchasing.

No, you can only use one discount code per order. Discount codes cannot be used in conjunction with subscription discounts at checkout. If you have a discount code you would like to use, kindly add the product to your cart using the 'one-time purchase' option.

If you're unable to log into your account, follow these steps to troubleshoot the issue:

• Check that you’ve created an account: Having placed an order or even having a subscription does not automatically mean you have an account. If you haven’t registered before, you’ll need to create an account using the same email you used for your orders.
• Reset your password: Click "Forgot Password" on the login page and enter your email. Check your inbox and junk/spam folders for the reset email. If you don’t receive a reset email, it’s likely that no account exists under that email, and you’ll need to create one.
• Create an account: If you discover you don’t have one, simply sign up using the same email you used for past orders. Once registered, you’ll be able to access your order history, loyalty points, subscriptions, and other account features.

Longevity Rewards is our loyalty programme designed to reward you for the things that genuinely matter (staying subscribed, building a long-term health routine, and spending with us over time). Rewards are issued as store credits that can be applied at checkout.

If you have an active subscription, you earn credits by staying subscribed without cancelling. Credits are unlocked at the following milestones:

• 3 consecutive renewals = £5 credit
• 6 consecutive renewals = £10 credit
• 12 consecutive renewals = £25 credit

Your streak is based on consecutive renewals. Skipping a renewal does not reset your streak, only cancelling does.

If you purchase on a one-time basis, your credits are based on cumulative spend:

• £150 spent = £5 credit
• £300 spent = £10 credit
• £500 spent = £25 credit

Credits are not added after every order. They are unlocked in a lump sum once you cross a threshold.

Skipping a renewal does not break your streak. Your milestone count continues from where it left off when your subscription next renews. Only cancelling your subscription resets your streak.

If you cancel your subscription, your streak resets to zero. If you re-subscribe in the future, your consecutive renewal count starts again from your next renewal.

Credits are applied at checkout. They will appear as a payment option when you're logged in to your account and have an available credit balance. You can also redeem your existing credits towards a subscription order through your account.

The great news is that your credits have no expiry date! You can redeem them whenever you wish.

Tiers are used for segmentation and reflect your relationship with Youth & Earth. They do not affect how credits are earned or redeemed.

• Bronze: the default tier for all customers, no sign-up needed
• Silver: for active subscribers with 2 or more successful renewals
• Gold: for subscribers of 6+ months, or customers with £300+ in lifetime spend

We've migrated from loyalty points to credits. Any points you had in your account have been converted into credits and added automatically, rounded up, not down. You don't need to do anything. Your credits will be available at checkout on your next order.

We value your feedback! Around three weeks after your order, you’ll receive an email from Feefo, our trusted feedback partner, where you can leave a review about your experience.

Leaving a review doesn’t just help others discover Youth & Earth - it also helps the planet. Thanks to Feefo’s Treefo initiative, every review contributes to tree-planting projects that restore landscapes and tackle climate change. We’ve committed to funding 50 trees per month to make a real impact worldwide.

If you’re not completely satisfied with your order or experience, we’d love the opportunity to make things right - please contact us first at support@youthandearth.com, and we’ll be happy to assist you.

Yes! We reward customers for taking the time to share their experience:

• Leave a Trustpilot review = £5 credit
• Leave a Feefo review = £3.50 credit

Credits will be added to your account once your review has been verified.
