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.

Nous recommandons de conserver notre poudre de NMN au réfrigérateur afin de préserver sa qualité et son intégrité, surtout si vous vivez dans un pays chaud.

Nous recommandons de conserver nos produits en gélules dans un endroit frais et sombre, à l'abri de la lumière directe du soleil. Cependant, pour nos produits NMN et NAD Max, nous recommandons de les conserver au réfrigérateur.

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 NMN powder to be taken in the morning and placed under the tongue as that allows it to be absorbed faster and has a higher bioavailability because it is absorbed by the capillaries in your mouth, instead of your stomach like most supplements. It can also be combined with Preservage to boost its effectiveness, as they have a synergistic effect on each other, making them more potent when they are used together.

Glutathione works very well with R-Alpha Lipoic and Vitamin C as both help recycle the Glutathione and have a synergetic effect.

The majority of our supplements work best when taken in the morning on an empty stomach. However, we do recommend to check on the back of each individual product packaging or the relevant product page for specific instructions on when to take each supplement. Spermidine, MenoCare+, Tocotrienols, Releafand Spore Probioticspecifically should be taken with a meal or shortly after as this will both maximize their effectiveness and reduce the possibility of gastrointestinal (GI) disturbances.

Nous conseillons toujours de vérifier sur l'emballage les instructions spécifiques sur la manière et le moment de prendre chaque supplément, ou la page produit correspondante sur notre site web.

Pour les produits en gélules, nous recommandons de les prendre avec un verre d'eau. Si vous avez du mal à avaler les gélules entières, vous pouvez les ouvrir et les ajouter à un liquide froid.

Pour notre poudre et nos gélules de NMN et NR en particulier, nous recommandons de les prendre le matin à jeun, de les placer sous la langue et de les laisser se dissoudre. Attendez ensuite au moins 30 minutes avant de prendre un repas.

Si vous trouvez le goût de la poudre trop fort, vous pouvez la mélanger à un verre d'eau froide, ou l'ajouter à un bol de yaourt, un smoothie ou toute autre boisson froide. Nous ne recommandons pas d'ajouter la poudre directement au mixeur, car cela pourrait affecter l'intégrité du produit. Veuillez donc ajouter la poudre à un smoothie ou à un jus de fruit une fois qu'elle a été mixée, et mélangez-la délicatement à l'aide d'une cuillère. N'ajoutez pas la poudre à des boissons chaudes ou à des aliments chauds.

Both supplements are made with the same ingredient. However, there is a difference in how they are administered. NMN is most effective when taken as powder under the tongue as it is absorbed by the capillaries in your mouth and the GI Tract is bypassed. Many of our customers use the capsule version and they are happy with the results they are receiving.

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.

Le NR et le NMN contribuent tous deux à augmenter le NAD+, mais ils agissent par des voies différentes dans les cellules, car ils sont à une étape enzymatique près, les molécules étant étroitement liées. On estime que le NMN fonctionne mieux dans les cellules et le NR dans d'autres organes.

Nous recommandons généralement de prendre la poudre de NMN par voie sublinguale, car c'est à ce moment-là que nous obtenons les meilleurs résultats. En général, deux mesures par jour sous la langue suffisent, il suffit de les tenir et de les laisser se dissoudre. Cependant, si vous n'aimez pas ce goût, les capsules NR Delayed Release seront plus fortes que le mélange de NMN dans l'eau.

Il est arrivé que des clients n'ayant pas obtenu les résultats escomptés avec le NMN reviennent au NR et obtiennent des résultats positifs.

Tous nos produits liposomaux sont créés à l'aide d'une technologie liposomale. Les compléments liposomaux utilisent une méthode d'administration unique qui permet à un plus grand nombre de nutriments contenus dans un produit d'être absorbés par l'organisme. L'utilisation d'une technologie liposomale pour les suppléments permet une meilleure absorption, une biodisponibilité 8 fois supérieure et une meilleure biocompatibilité avec le corps humain.

None of our capsule, softgel, or powder products would break a fast. The only products that could break a fast are our liquid Liposomal products, as they contain a small amount of calories.

Some people may find the taste of R-Alpha Lipoic Acid too strong. We recommend mixing it with cold water or juice to soften the taste. Liquid liposomal products should never be mixed in hot liquids or blended, as this will disintegrate the liposomes.

All of our products are vegan with the exceptions of Superba Krill Oil, Tocotrienols, Phytoceramides (Lipowheat), Mitochondrial CoQ10 and Vitamin D3 + K2.

Oui, toute notre gamme de produits est sans gluten.

We ship to various destinations worldwide, but there are some exceptions such as US, South America, Africa, The Caribbean, Tenerife (we do ship to the rest of 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 enquiries@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.
