Understanding the potential Benefits of NAD+ and L-Glutathione
-
Anti-Ageing From The Inside Out
Due to the detoxifying nature of L-Glutathione and improved cellular efficiency from NAD+, both supplements may support anti-ageing. -
Improve Cellular Energy and Efficiency
Both L-Glutathione and NAD+ work at the cellular level. L-Glutathione detoxifies and cleans, while NAD+ improves cellular efficiency and regeneration.
-
Skin Brightening & Repair
L-Glutathione helps keep your cells clean and healthy for longer, while NAD+ supports regeneration. Research indicates this may improve skin health. -
Enhance Detoxification
Increase liver support and heavy metal removal

View ProductCommon FAQs
Can I take NAD+ & L-Glutathione on the same day?
Definitely. They are a great pair for boosting your cellular health. Just use different injection sites for each supplement.
What’s the difference between NAD+ & LG?
NAD and L-Glutathione supplements serve different purposes. NAD+ supports cellular energy production and overall metabolic function, aiding in anti-ageing and brain health.
L-Glutathione, on the other hand, is a powerful antioxidant that helps detoxify the body, boost the immune system, and promote even skin tone.
Both supplements contribute to overall health but target different aspects of cellular function.
What do the cartridges contain?
L-Glutathione Cartridges:
Each cartridge is packed with 10 doses worth (750mg) of active L-Glutathione and a small amount of sterile solution. Nothing else is added. Our L-Glutathione is the highest grade and purity on the market; we are the leaders & pioneers in all things wellness injections.
NAD+ Cartridges:
Each cartridge is packed with 10 doses (500mg) of the active ingredient nicotinamide adenine dinucleotide (NAD+), along with a small amount of sterile solution. Nothing else is added.
Â
How should I dispose of the micro-needles and used cartridges?
Dispose of any used items, such as your empty cartridges and needles in the designated sharps bin. When disposing of needles, it’s important to be cautious and ensure that they are not sticking out of the bin. This helps ensure a clean and responsible process.
No-one was home to receive my order. Will the order be ok unrefrigerated?
Both kits are perfectly fine at room temperature.
To put your mind at ease, NAD remains stable at room temperature for several weeks. It only begins to degrade after being exposed to temperatures above 30°C / 85°F for a few days. Even then, it is not harmful, though it may lose some efficacy. The same is true of L-Glutathione.
However, for your convenience and to ensure the maximum benefits to your wellness routine, we include a cool pack our combo kits to maintain optimal conditions in transit.
For optimal freshness, we recommend storing both in the refrigerator upon arrival and after opening, keeping it away from bright light and extreme heat.
Where's best to inject?
The syringes provided are intended for subcutaneous injections, which involve administering the injection just under the skin into the fatty tissue. We suggest using areas like the stomach, hips, or buttocks for these injections.
To administer, pinch the skin tightly between your finger and thumb with one hand, and with the syringe in your other hand, inject at a 45-degree angle. It’s important to rotate the injection site each time to avoid skin irritation. It’s normal to occasionally experience a bruise or a small bump at the injection site; simply make sure to inject in a different area for your next dose.
