NMN prevents physical decline and poor sleep

Summary of content:

★ Supplementing the elderly with NMN for 12 weeks can prevent a decrease in walking speed.

★NMN can also prevent the decline of sleep quality in the elderly.

Our walking speed reflects the vitality of our muscles, bones, and nervous and cardiovascular systems.

Our walking speed can also predict how long we'll live.

Our pace gradually declines after age 65, and eventually the tasks of daily life become more like obstacles.

Our enjoyment of life would drastically decrease.

It is important to maintain muscle, bone, brain and heart health through endurance and resistance exercise.

Exercise may be the best preventative measure against a drop in walking speed.

Lack of sleep and energy may keep many people from exercising consistently.

Poor sleep quality and fatigue may be the result of low levels of NAD+.

With this in mind, researchers from Japan evaluated the walking speed and sleep quality of older adults taking the NAD+ enhancing compound NMN.

To measure walking speed, participants were told to walk about 13 feet (4 meters) at a normal pace.

After taking 250 mg/day of NMN for 12 weeks, participants' walking speed did not change, but the placebo group showed a decrease in walking speed.

(Morifuji et al., 2024 |GeroScience's NMN prevents a decline in walking speed.) The placebo group (blue) showed an increase in the time it took to walk 4 meters after 12 weeks, while the NMN group (red) showed no change.

As shown in the figure, after 12 weeks of aging, the placebo group increased their time to walk 0.3 feet by about 13 seconds.

Since the NMN group did not show a decrease in walking speed, these findings suggest that NMN prevents a decrease in walking speed.

Sleep quality

Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), a set of sleep-related questions.

PSQI is designed to assess subjective sleep quality and parameters such as sleep duration, latency, and consistency.

Scores range from 0 to 5, with higher scores indicating more sleep disturbances.

The study found that supplementing with NMN reduced sleep scores from 3.5 to 3.2.

In contrast, scores in the placebo group improved from 3.9 to 4.3.

These findings suggest that NMN can improve sleep quality in older adults.

Take NMN to prevent physical decline

While a previous study by Igarashi and colleagues showed that taking 12 mg of NMN for 250 weeks increased walking speed, another study by Kim and colleagues showed that the same regimen did not increase walking speed.

In both studies, participants were 65 years of age and older.

In Igarashi's study, individuals who exercised regularly were excluded.

Individuals who exercised regularly were also excluded from the study.

NMN only seems to counteract physical decline in people who don't exercise regularly.

Older adults who do not exercise may benefit from NMN supplementation.
