Cell Revival - Product information
Is Cell Revival safe?
All ingredients in Cell Revival are GRAS certified. GRAS is U.S. FDA's safety index for the evaluation of food additives. This ensures our ingredients are safe. For example, NR, one of our main ingredients in Cell Revival, has been certified as a new dietary supplement. After undergoing rigorous testing, the adult dose daily limit was confirmed as 3mg/kg or 180mg.
How does Cell Revival help with maintaining youth and reversing ageing?
Ageing is a biological process characterised by a progressive accumulation of damage that finally leads to disrupted metabolic homoeostasis leading to cell damage. One of the hallmarks of ageing is the presence of mitochondrial dysfunction. As NAD+ levels decline, mitochondrial function is impaired, resulting in fewer mitochondria surviving. This vicious cycle of mitochondrial depletion results in many of the physical symptoms of ageing. In a recent human study, it is scientifically proven one serving of Cell Revival increased NAD+ levels by 33% in 8 hours. Therefore, Cell Revival can promote mitochondrial function which is an important component of ageing.
- Belenky P, Racette FG, Bogan KL, McClure JM, Smith JS, Brenner C. Nicotinamide riboside promotes Sir2 silencing and extends lifespan via Nrk and Urh1/Pnp1/Meu1 pathways to NAD+. Cell. 2007 May 4;129(3):473-84.
What is the relationship between Cell Revival and NAD+?
The proprietary formulation acts as a precursor to NAD+. The body loves NAD+ because NAD+ is the key that enables the mitochondria – the “power station” within the cell, to begin cellular energy production. In fact, research suggests that once NR is detected in the body, the body quickly begins converting it to NAD+ within the cells. The benefits of enhancement of NAD+ level is multi-folded, it includes: Improved cognitive function，Improved endurance due to enhanced mitochondrial function，Improvements in occasional sleep disturbance.

How does Cell Revival ensure the highest quality?
Cell Revival is manufactured in California under cGMP (current Good Manufacturing Practice) regulations, enforced by the FDA. Prominent researchers from America’s finest institutions including Harvard and MIT have already published studies on various conditions regarding the active ingredients in Cell Revival, the conditions include: Anti-Ageing – Extends Lifespan in Animal StudyWeight Management – The elevation of NAD+ level promotes resistance to diet-induced obesity. Glucose Management - Prediabetic and type 2 diabetic mice experienced remarkable control of high blood sugar. Cognitive Function – As demonstrated in animal in-vitro studies and in an in-vivo mouse study, the elevation of NAD+ level improves cognitive function and protects against axonal degeneration associated with ageing.
Cell Revival - User Information
Can one overdose on Cell Revival?
No. As mentioned above, all the ingredients in Cell Revival have GRAS (generally recognised as safe) status, which defines the levels at which it can be incorporated into various foods and beverages. Furthermore, the formulation and dosage of an individual ingredient are carefully researched and advised by our science team, thus Cell Revival is a product we have pride on top quality and safety.
What age should I start taking Cell Revival?
Scientific research has shown that ageing begins at 26 years old. We recommend starting taking Cell Revival as a supplement then.
What is the shelf life of Cell Revival?
The shelf life is 2 years. Please keep Cell Revival in a cool and dry place. The best before date is printed on the bottle.
Can Cell Revival cure cancer?
Our product has not been proven to cure cancer yet, but it may have a role to play in preventing the onset of cancer in the first place, as cancer in older people is frequently caused by a depletion in oxygen levels in the body, which can lead to the onset of age-related cancer.
How am I supposed to eat Cell Revival?
You should take 2 capsules of Cell Revival on an empty stomach with a large glass of water every morning.
What happens if I stop eating Cell Revival?
Your body will store the regenerated capsules that you absorbed until depleted.
Can I eat other medication along with Cell Revival?
As Cell Revival is a health supplement, you may consume other medication at the same time with no harmful effects. However, we always encourage you to consult your family doctor to provide professional advice based on your medical history to evaluate whether or not Cell Revival is suitable.
Can everyone eat Cell Revival? How about if I'm pregnant?
Yes, Cell Revival should be suitable for everyone. However, we do not recommend pregnant women to eat it as pregnant women may have unpredictable reactions.
I remember there used to be 30 capsules per bottle, but now there are 60 capsules per bottle. Is this another product?
It is the same product. Originally there were 30 capsules per bottle, and users were supposed to consume 1 capsule per day. However, we strengthened the formula and the new bottle has 60 capsules in total. Users should consume 2 per day.
I have been taking Cell Revival for a few days now, and I am feeling fatigued/drowsy these days. Is that normal?
Yes, this is normal. The drowsiness and fatigue you are experiencing are signs of "recovery". Your cells are reacting to Cell Revival and are replenishing, detoxifying and repairing your body tissues. This helps you to achieve REM sleep easier. Once your body tissues have been replenished, you will no longer feel fatigued and you will be more energetic than before.
How many bottles should I buy for my first time?
Generally, users begin to see noticeable differences in 2-3 months. Therefore, we recommend buying 3 months worth of Cell Revival (3 bottles).
I have been taking Cell Revival for 3 weeks already but I still don't see any noticeable change. Why is that?
Everyone's physiology is unique, and results vary from person to person. Some individuals have seen results as early as 1-2 weeks in, whilst others may take 2-3 months to notice that improvement.
Do I have to continue eating Cell Revival?
As Cell Revival is a health supplement, it is not a necessity for you to keep consuming it.
Will I age rapidly if I stop consuming Cell Revival?
No. After consuming Cell Revival for a period of time, the anti-ageing effects will be noticeable. After stopping, the effects of Cell Revival will stop but there will be no negative consequences.
Will Cell Revival help me with my grey hair?
Many of our customers with grey hair noticed a difference in their skin after 2-3 months. Cell Revival will be able to reduce the appearance of grey hair if it is caused by ageing. Under other circumstances such as being caused by stress or diseases, we cannot guarantee any results regarding grey hair.
