What is inside the NMN supplement?
Each capsule contains 500 mg of >99% pure β-Nicotinamide Mononucleotide (NMN), a derivative of vitamin B. We ensure that our capsules contain no fillers or bulking agents. They are non-GMO and suitable for both vegans and vegetarians.
Each jar provides a one-month supply with 30 capsules.
When should I take NMN?
NMN can be taken at any time (Although we recommend taking first thing in the morning) of the day to enhance energy, drive, and resilience. Athletes often report a noticeable increase in energy when NMN is taken 20-30 minutes before exercise, aligning with studies showing NMN absorption into the bloodstream within 5-10 minutes. It also crosses the blood-brain barrier, increasing NAD+ levels in the brain, which may improve cognitive function.
Taking NMN in the late afternoon has also been shown to improve sleep quality.
Can I get NMN naturally?
NMN is naturally found in foods like broccoli, cucumber, and avocado, but in very small amounts (approximately 0.25-1.9 mg per 100g). To match the NMN content of one 500 mg capsule, you would need to consume over a kilogram of broccoli daily. Therefore, supplementation is the most effective way to boost NMN and NAD+ levels.
Is NMN safe?
A 2019 study involving 10 healthy Japanese men found that daily doses of up to 500 mg of NMN are safe. Many longevity experts, including Prof. David Sinclair, take up to 1g daily. Multiple human studies using doses as high as 1200 mg have reported no side effects. NMN is recognized as a non-pharmaceutical, naturally occurring compound and is generally recognized as safe (GRAS).
We recommend taking 1 capsule per day.
What other supplements work well with NMN?
To enhance the longevity effects of NMN and improve activation of key anti-aging pathways, we recommend exploring our blogs on NMN and Longevity. Our Longevity Pack includes:
- NMN: Our NMN is 99.5% pure, highly absorbable, and boosts energy production, AMPK, and sirtuin activation.
- Quercetin: Inhibits the CD38 enzyme that breaks down NAD+, enhancing NMN’s effects.
- Resveratrol: Activates sirtuin pathways. The most effective form, trans-resveratrol, works synergistically with NMN.
- Coenzyme Q10: A crucial mitochondrial electron transporter and antioxidant, it delays brain atrophy. A study found that participants taking CoQ10 cycled longer with less fatigue. Its synthesis relies on several B vitamins and vitamin C.
- Vitamins D3 and K2
- B Complex (Methylated Active Form)
What’s the difference between niacin (vitamin B3) and NMN?
NMN is more effective than niacin for boosting NAD+ levels and activating sirtuin pathways. Nicotinamide (NAM), a form of niacin, must first convert to NMN before becoming NAD+. High levels of NAM can inhibit sirtuins, reducing the benefits of NAD+. Additionally, high doses of niacin and nicotinamide can cause flushing, which NMN does not.
Will NMN help me live longer?
Research suggests that NMN may help extend lifespan by boosting NAD+ levels in the body. Studies on aged animals have shown that higher NAD+ levels can lead to longer lifespans.
Is NAD+ better than NMN?
NMN and NAD+ are distinct but related. NMN is the most efficient way to boost NAD+ levels, as it is transported into cells and then converted to NAD+. Currently, no direct transporter for NAD+ has been identified, meaning it must first break down into NMN or NR before entering cells and reassembling as NAD+. A 2018 study by Grozio et al. identified Slc12a8 as a transporter that moves NMN into cells.
How quickly can I expect results from taking NMN?
Results can vary depending on individual factors, but studies have shown that NMN can significantly boost NAD+ levels in humans within just 30 days.
Is NMN legal in the UK?
Yes, NMN is legal in the UK and available for purchase as a dietary supplement. However, it's crucial to buy from trusted sources to guarantee the product’s quality and safety. This is why, at GroovyNMN, we buy from the most researched and reliable supplier in the world.
Why take NMN?
Boosts energy levels and reduces oxidative stress
NAD is essential for the function of mitochondria, the energy factories of the cell. NMN improves energy levels and reduces free radicals, which are byproducts of energy production.
Helps in DNA repair
NAD participates in the DNA repair of mutations. As we get older, DNA repair uses more and more NAD from the cell’s pool. By covering the extra need for NAD, NMN supports DNA repair.
Improves endurance and strength
NAD acts on the skeletal muscle and enhances aerobic capacity. As a result, NMN improves, endurance and strength. Also, it may delay frailty and muscle dysfunction that come with age.
Promotes brain health
NMN may reduce oxidative stress and inflammation in the brain. As a result, it may promote better memory, and cognitive function and protect from diseases like Alzheimer’s.
Improves insulin sensitivity
Good insulin sensitivity, which is essential for healthy blood glucose levels, lessens with age. NMN improves insulin sensitivity and may prevent related diseases, such as type 2 diabetes.
Supports healthy aging
NMN enhances the activity of sirtuins, the proteins of longevity. By doing so, it supports many aspects of healthy aging including healthy metabolism, heart and brain function.
How Much NMN Do I Need To Take For It To Be Effective?
Recommended Daily Dosage of NMN Powder by Age:
✔ Ages 30-40: Take 500mg daily
✔ Ages 40-60: Take 750mg daily
✔ Ages 60+: Take 1,000mg daily
For best results, take your NMN capsules in the morning to naturally boost energy throughout the day.
Note: Always consult with your healthcare provider before starting a new supplement, especially if you have any existing health conditions or are on medication.
