"After vigorous exercising, my muscles are surprisingly not sore!"


Usually after hiking, my thighs will definitely have muscle soreness for a few days, especially in the past two years. I have been taking pure NMN for about two months, and I have hiked twice recently, only to find that my legs are not sore at all, which is very surprising! At first I take NMN as a placebo; but now I would strongly recommend it to my relatives and friends! (Translated text)

"Followed expert recommendation"


I saw a podcast with David Sinclair then I switched from niagen to nmn and added resveratrol. (Translated Text)

"Lost weight!"


I asked a friend to buy NMN for me in Hong Kong just to give it a try. I took 1000 mg every day for about a month and a half. Unexpectedly, I lost weight without doing anything different! (Translated text)

Wenzhou, China

"May have helped in weight loss"


Tried resveratrol and NMN for 2 weeks, I’ve lost some weight, but maybe placebo effect, not sure. I didn’t have any health problems or energy issues, so I can’t say if there is any effect neither as I didn’t do any bf/af blood test.

Tsing Yi, Hong Kong

"I chose Rescence products based on the ingredients and product details"


After comparing Rescence to other brands, I have chosen Rescence products based on the ingredients and product details, the lack of capsules is also one reason why I chose Rescence.  Everyday I take both NMN and resveratrol together after breakfast.  I have been taking it for two weeks. I feel that I am not easily tired and my energy level is much better. I have recommended my friends to purchase the products too. I would take Rescence for the long term particularly if the price can be even cheaper.

"Take NMN to prevent eye aging"


I did a DNA test earlier and learned that I am more likely to have AMD than most people. As a means to prevent my vision from weakening, I started NMN. It’s hard to say if it works, but your product is white powder and GMP certified, so I think it’s reliable, so I bought it.

New Jersey, USA

"My complexion appears to be more even"


I have been taking resveratrol and NMN (4 scoops each) since the beginning of January. Recently, I feel that my complexion seems noticeable even. In addition, I previously noticed that the bags under my eyes have changed to two layers (probably because of my age). The eye bags seem to have improved also, I will continue to take the products and see what other changes there are. (Translated text)

"No capsule, good!"


I bought your NMN, it’s good that it’s not mixed in cheaper vitamins in capsules with beige powder. (Translated text)

"Pure White Powdered NMN and Resveratrol"


Because there are many fake products on the market, it took me a long time to find the product that is of white powder without adding any other ingredient.

Kowloon Tong, Hong Kong

"SGS is trustworthy"


There are many suppliers in the market that use an unknown Micro Quality Lab for product qualification. Your quality control and product safety are SGS, a world-renowned verification company that our company used to work with, so I know that your products are relatively reliable, and I feel more assured to consume or to get for my family.

What NMN Dosage to Take? What's Beneficial?

In animal studies, it has been found that increasing NAD+ levels can help reverse a number of age-related illnesses, such as heart disease, diabetes, and neurodegeneration.

Can I Obtain Enough Resveratrol From Food?

Resveratrol For Health Dr. David Sinclair, currently a professor of genetics at Harvard Medical School, was an early resveratrol researcher. In 2003, he and his

NMN supplement was shown safe without any side effect with up to 1200 mg per day for 6 weeks – 10 male and 2 female amateur runners between 27 and 50 years old, reported no obvious side effect.

People who have used NMN supplements have not yet experienced any substantial negative side effects of taking NMN, which is a positive development.

Not enough studies are conducted on humans in preventing or suppressing cancer cells. It is always advised to consult physicians prior to taking any supplements. 

NMN is most effective when taken in the morning within six hours after being awake and can be ingested with water or food. NMN, boosting NAD+, has an impact on the circadian rhythm.

Dr. David Sinclair, the longevity genetic expert and Harvard professor, has been using NMN over a decade. He dissolves the white powder form of NMN and resveratrol in either Greek yogurt or organic cold press olive oil before ingestion every morning.

Resveratrol requires the fat source to ingest along hence the dissolution in Greek yogurt or in olive oil prior to oral intake. 

Nicotinamide adenine dinucleotide (NAD+) is a critical coenzyme on which the mitochondria in each cell of our bodies rely to perform their essential tasks. This molecule is required for approximately 500 enzymatic reactions that govern practically every significant biological activity from cellular communication, DNA repair to metabolism and organ functions. For more details read this article backed by science

As the levels of NAD+ decreases as we age, it is crucial to boost the NAD+ so as to avoid all age-related diseases and discomforts. Boosting NAD+ can be achieved through exercising, diet and ingesting NAD+ booster supplements.

Directly taking NAD+ does not raise NAD+ level due to low bioavailability through intestines and its large polarity preventing it to be absorbed. Read this publication for details.

It is proved that only taking precursors of NAD such as NMN and NR can increase the NAD+ levels in the body. 

NMN products often shown with a specific number: NMN 6000, NMN 9000, NMN 10000, NMN 15000 or NMN 18000. For Rescence, Pure NMN 15000 and Pure Resveratrol 15000 represent the exact strength of the active ingredient NMN (99% purity) or trans-resveratrol (98% purity) in each product. As both are in pure powder form, 15000 means 15000 mg of NMN and 15000 mg of trans-resveratrol (1 g = 1,000 mg). 

Consumers should be aware that this is not applicable for all brands. Some brands may not show how much milligram of resveratrol or NMN in each capsule due to minimal content and some would add up the milligrams of multiple ingredients to package under NMN 18000 for example. while the actual strength of NMN is less than what is made believe.

At Rescence, we value integrity. We recommend that whether it’s for supplements or food, always check the label to see no inferior ingredient is mixed in to support your wonderful longevity journey!

In general, if a person consumes resveratrol in small doses over a short period of time, they will not suffer any negative effects. However, with daily dosages of 2.5 g or more, the following adverse effects may occur:

One participant in a 2016 study got fever and cytopenia (low blood cell count) when consuming 1.5 g resveratrol per day for 6 months.

When taken orally: Resveratrol is commonly found in modest levels in foods. When used orally in quantities of up to 1500 mg daily for up to three months, resveratrol supplements may be safe. For 2-6 months, higher dosages of up to 2000-3000 mg daily have been used successfully. These greater dosages, however, are more likely to induce gastrointestinal trouble.

Skin Application: Resveratrol may be safe to take for up to 30 days.

Nasal Spray: Resveratrol is possibly safe when used for up to 4 weeks.

In those with bleeding problems, resveratrol may decrease blood coagulation and increase the risk of bleeding.

Resveratrol has the potential to mimic estrogen. If anyone has a disease that might be exacerbated by estrogen exposure like breast cancer, uterine cancer, ovarian cancer, endometriosis, or uterine fibroids, they avoid using resveratrol. Women having a history of estrogen-sensitive malignancies, such as breast, ovarian, and uterine cancers, should avoid resveratrol supplements until more is known about its estrogenic effect in humans.

The below list shows the dosages used in recent human trials:

Oral intake of 25 mg of resveratrol revealed that it has extremely low bioavailability.

75 mg was given to type 2 diabetes patients with improved neurovascular coupling capacity and improved cognitive performance.

270 mg was given to overweight, obese or postmenopausal people with improved flow-mediated dilatation.

80 mg and 282 mg were given to overweight or obese subjects with improvement in mitochondrial capacity, fat oxidation stimulation.

250-500 mg of trans-resveratrol showed improvement in cerebral blood flow in healthy subjects.

In a meta-analysis of the effects of resveratrol on glucose control and insulin sensitivity, doses ranging from 8 to 1,500 mg/day and durations ranging from 2 weeks to 6 months were used; these studies included patients with type 2 diabetes mellitus, cardiovascular disease, obesity, or metabolic syndrome, as well as healthy volunteers.

Resveratrol at a high dose (1,000 mg twice daily) was administered for up to one year in patients with mild to severe Alzheimer’s disease and 500 mg three times daily for six months in individuals with non-alcoholic fatty liver disease. The first dose for exercise capacity was 500 mg twice daily for one week, followed by 1,000 mg twice daily for the remaining three weeks.

A continuous intake of moderate dosage 450 mg – 1000 mg / 1 g renders positive health effects associated with oxidative stress and inflammation.

5,000 mg / 5g of resveratrol was given to patients of Friedreich ataxia for 12 weeks showing improvement in neurologic function, audiology and speech measures as well as oxidative stress marker plasma.

500 mg, 1000 mg, 2,500 mg, and 5,000 mg were given to 40 healthy volunteers for 29 days resulting in a reduction of cancer risk. The highest reduction was observed with a 2,500 mg / 2.5 g dosage.

People have varying tolerances for resveratrol, and there is no universally advised amount. People should see their physician determine the dose that is both safe and useful for their body.

Bioavailability of resveratrol is higher on an empty stomach (8 hours of fasting) and when taken in the morning due to the influence of the circadian rhythm.

Dr. David Sinclair, the longevity genetic expert and Harvard professor, has been using NMN over a decade. He dissolves the white powder form of NMN and resveratrol in either Greek yogurt or organic cold press olive oil before ingestion every morning.

Resveratrol requires the fat source to ingest along hence the dissolution in Greek yogurt or in olive oil prior to oral intake.
