Nicotinamide riboside, also known as NR is one our most popular supplements and an alternative form of vitamin B3. When consumed, NR is converted into NAD+, which is a naturally occurring process.
Research has shown that by the time we hit 50, our NAD+ levels will be half of what they were in our 20’s.
As we age, we see significant changes in both our appearance and our overall energy levels. Our skin becomes thinner and less smooth and also begins to sag and wrinkle. At the same time easy tasks can become more difficult, with more rest being needed between them.
Although this is a natural part of aging, the process itself can be slowed dramatically with the right diet and lifestyle.
Our NR is over 99% pure and has been independently lab tested to guarantee its quality. It’s also 100% natural, non-GMO, naturally gluten free and vegan friendly.
With every order we provide a FREE 0.5g scoop, with all delivery being free of charge throughout the UK.
The alternative to taking either NR or NMN is cycling between the two of them
Cycling supplements can be a smart move. With NR and NMN, the body produces a certain amount, depending on your age. However, there is the risk that if you introduce a higher than natural level of these two precursors, the body’s metabolism may readjust and produce less of its own after a while, thus negating any potential benefits of a supplement. To counteract this problem, it is worth considering ‘cycling’ the two, by taking either NR for, say, a two-week period, then switching to NMN for a two-week period, then switching back to NR again, and so on…Another approach may be to alternate every day. Further studies are needed in this area.
Recommended Daily Dosage:
0.5 grams per day
2 grams per day.
Like all vitamins, supplements and beneficial substances, it theorised that periodic breaks from NR (one to two days off) on a weekly basis. Further studies are needed on this and there is no firm evidence to suggest whether this practice is beneficial or not, but the theory is supported by a number of knowledgeable people in the field of human biology.
If you are on prescribed medication or have been medicating for a long term previously, then it is best to consult with your doctor before starting with NR.
Keep the contents in the provided packaging or an airtight glass jar. Keep away from sunlight and avoid exposure to a temperature above 24 degrees Celsius. Keep in a cool dry place and don’t expose the contents to moisture. This product can be kept in a fridge or refrigerator.
Longevity Box NR powder is provided and supplied in re-sealable food-grade and food-safe pouches that are transparent on one side. NR does experience a degree of degradation over time. This degradation is still slow at room temperature but can be slowed further by storing it in the refrigerator. If you are planning to buy more than 3 months worth then it is recommended to store in the refrigerator.
Scooping spoon are provided with every order that carries 125 mg of NR powder when leveled.
Longevity Box also provides glass jars for storing your NR powder. These jars can contain approximately 50g the supplement, are re-sealable, and airtight. Ideal for people who have upped their dosage and need to take it on the go without having to deal with the hassle of using pouches.
