Nicotinamide Mononucleotide (NMN) is a substance that helps produce nicotinamide adenine dinucleotide (NAD+), a molecule found in every cell of the body. NAD+ is important for energy and cell repair, but its levels decrease as we age. Taking NMN as a supplement can help boost NAD+ levels, which may reduce the effects of ageing, such as lower energy, slower metabolism and decreased cell function.

No, NMN is not the same as vitamin B3, although they are closely related. While NMN is derived from vitamin B3, it is a distinct compound. Vitamin B3, also known as niacin, comes in three forms: nicotinic acid, nicotinamide and nicotinamide riboside. NMN, on the other hand, is a product of the metabolism of these forms of vitamin B3. NMN itself is not a vitamin but is, instead, a key precursor to NAD+, a molecule essential for energy production and cell repair.

NMN supplements may help slow down ageing by increasing NAD+ levels in the body. NAD+ is important for energy and cell repair, but its levels drop as we age, which can lead to problems like cell damage, memory issues, and reduced energy. Taking NMN can help raise NAD+ levels, which might support the body's natural functions and help delay ageing. While the effects are gradual, NMN could improve overall health and help the body age more healthily.

Yes, it is generally safe to take NMN supplements every day. Studies have shown that NMN is well tolerated and has few side effects. Most research suggests that up to 1,200 mg a day is safe, although people typically take around 300 to 500 mg per day.
