If you intend on keeping your NMN for over three months, then storage in the refrigerator is recommended to slow its degradation. However, degradation is still slow even at room temperature.

Please see the image below, illustrating testing carried out on the product provided by Renue By Science, formerly Alive By Nature.

NMN production techniques have improved immensely over the past few years. As a result, almost all NMN on the market today, including Alive By Nature’s, is stabilised, meaning degradation is slow even at high temperatures.

Keep your supplements in a cool, dry place away from sunlight, and there will be little effect on your NMN. Avoiding moisture is the biggest concern.

We keep all products in cold warehouse storage before dispatch. Therefore, your NMN will not be affected in storage or short time in delivery transit.

Studies and David Sinclair has stated the older you are (the less NAD you have in your body) the more effective NMN supplementation has on your NAD levels. It is safe to take our products at any age, but we would recommend any age over 30.
No one can give a guarantee that increased NAD would have no effect on tumour growth. But, in all studies to date, there has been no increase in frequency or severity of cancer. Humans have “cancer” cells in our bodies constantly, but usually our immune system is able to stop them until we get older. Diminished NAD as we age is a big hinderance to fighting infections and cancer, so there is reason to believe increased NAD will help fight cancer more than it will help cancer cells grow.
There are no studies comparing sublingual and capsules however, the sublingual form of the tablets and powder have been developed so that a proportion of the NAD or NMN is absorbed into the blood stream rather than through the digestive system. As the absorption rate of different molecules delivered through the sublingual route can be 3 to 10 times greater than oral route we have partnered with the leading pharmaceutical sublingual products manufacturer to supply you with the first NMN and NAD+ supplement sublingual powder, tablets, liquid drops and nasal spray that have the ideal characteristics to ensure efficient and rapid uptake.
