Who needs NMN?*

Cognitive and physical changes
As you age, some aspects of memory and mobility may naturally fluctuate.

Daily movements or activities become more challenging
A slower metabolism can contribute to fatigue, weaker nails, dry skin, and gradual weight changes. Metabolic rate naturally declines starting in your 20s.

Sleep difficulties
Stress and daily life demands may affect sleep quality, leading to tiredness during the day.

Visible changes to skin
Fine lines, wrinkles, and variations in skin tone and hydration may appear over time.

NMN is intended for healthy adults as a dietary supplement. It is recommended that pregnant or breastfeeding individuals, or anyone taking medications or with existing medical conditions, consult a healthcare practitioner before use.
What is Mitsuwa® Ocean Blue Pure NMN made from?

What color is the Mitsuwa Ocean Blue Pure NMN powder inside the capsule?
The NMN powder may range in color from white to reddish yellow. This variation is normal, meets safety standards set by the Japanese manufacturer, and is safe for consumption.
How do NAD+ levels in the body change with age?
NAD+ levels naturally decline as people age.
Research, including the Australian study “Age-Associated Changes in Oxidative Stress and NAD+ Metabolism in Human Tissue,” has found that the average NAD+ level in a newborn is 8.54, while the averages for the 30–50 and 51–70 age groups are 2.74 and 1.08, respectively.
Lifestyle factors such as diet, sleep, alcohol use, and smoking can also influence NAD+ levels.*
Why supplement with NMN instead of NAD+?
NAD⁺ is a vital molecule that helps your cells produce energy and maintain healthy function. However, taking NAD⁺ directly isn’t very effective because it’s a large molecule that is poorly absorbed by cells. NMN is a smaller precursor that can enter cells more readily and is quickly converted into NAD⁺ in the body. Supplementing with NMN is therefore a more efficient way to support healthy NAD⁺ levels, cellular energy, and overall wellness.*
What does the NMN12000 on the package of Mitsuwa® Ocean Blue Pure NMN represent?
The ‘12000’ in NMN12000 represents the total milligrams of NMN in each bottle of Mitsuwa® Ocean Blue Pure NMN. Each bottle contains 60 capsules, with 200 mg of NMN per capsule.
How does NMN compare to Nicotinamide riboside (NR)?
Nicotinamide riboside (NR) is a naturally occurring form of vitamin B3 and a precursor to NAD⁺, an essential molecule for cellular energy and metabolism. When taken as a supplement, NR must first be converted into NMN, which is then converted into NAD⁺.
NMN supplements, on the other hand, are one step closer to NAD⁺ and can be more readily converted by the body.* This may make NMN a more efficient way to support healthy NAD⁺ levels, cellular function, and energy.*
