01 . Our certifications & third-party lab tests
Every certificate is issued by an independent body. Every lab report is produced by an accredited third-party laboratory — not us.
Independently certified. Not self-declared
Our Ang Mo Kio facility holds NSF GMP certification, SOCOTEC GMP certification, and U.S. FDA registration. All three are issued by independent bodies. None are self-declared. This product is also MUIS Halal certified, covering all ingredients, manufacturing processes, machinery, and staff protocols. GMP certification is the international standard for supplement quality.
Third-party tested. Every batch, every product.
Every batch is independently tested by Eurofins Singapore, one of the world's largest testing laboratory organisations for heavy metals and microbial safety. Raw material purity is also tested by SGS, returning >99.99% β-NMN content. Eurofins also tests our actual product content, returning results confirming our NMN meets label claims.
View all certificates and 3rd party lab reports
Every product's heavy metal and microbial lab reports are publicly available. No sign-in required.
Certificates shown on the linked page are the originals — unedited, directly from the issuing bodies.
02 . Made in Singapore's Largest NSF GMP Certified Supplements Factory
Our family has been in the nutrition industry for over 20 years. The same manufacturing facility also uses the same machines, ingredients and processes to manufacture supplements and health foods for hospitals, clinics, and global brands. Now with Estalife, we sell directly to you, without the middlemen.
Certifications — what they actually mean
03 . Your cells become less efficient at producing energy, and it starts in your 30s.
NAD+ is the coenzyme that powers every cell in your body. It supports over 500 enzymatic reactions — including energy production, DNA repair, and cellular maintenance. The problem: as you age, your body generates less of it. And it becomes alarming as you reach your thirties.
McReynolds et al., 2020 (NIH)
"NMN is the direct precursor your body uses to make NAD+. Unlike NAD+ itself — which is too large to enter cells — NMN is absorbed and converted intracellularly where it's needed."
04 . What's inside — the single active ingredient
500mg
Beta-Nicotinamide Mononucleotide (NMN)
NMN is the most direct precursor to NAD+. Once ingested, it is rapidly absorbed and converted intracellularly into NAD+ via the Salvage pathway. At 300mg/600mg/900mg — the doses used in the NUS clinical study — it produces measurable blood NAD+ elevation within 8 weeks.
Estalife NMN is tested by independent third-party to ensure exceptional quality and purity. Verified by SGS, a global leader in testing and quality assurance, our NMN meets the highest purity standards at >99.99%.
In addition, finished product testing is conducted by Eurofins, a reputable international laboratory, to confirm the actual NMN content per capsule. Each serving is verified to deliver the stated 500 mg dosage.
This comprehensive testing process ensures you receive high-purity, bioactive NMN—free from degradation and low-quality materials.
We test the finished product, not just the raw material. NMN degrades rapidly during manufacturing if the facility or operators are inexperienced with the ingredient. As one of Singapore's first manufacturers of NMN supplements, our factory has built up an expertise backed by third-party lab tests to confirm our manufacturing capabilities.
05 . Key benefits — what the science shows
Cellular energy production
NMN converts to NAD+, the key electron carrier in mitochondrial energy production. Powers every cell, every day.
Rajman et al., Cell Metabolism, 2018 ; Imai & Guarente, Trends in Cell Biology, 2014.
Clinically raises NAD+ levels
A 2025 Nature Metabolism study confirmed NMN doubled circulating NAD+ over 14 days. 15 randomised controlled trials confirm the effect.
Okabe et al., Nature Metabolism, 2025
DNA maintenance support
NAD+ activates PARPs — the enzymes that detect and repair DNA strand breaks. Without enough NAD+, these pathways slow significantly.
Rajman et al., Cell Metabolism, 2018
Healthy ageing pathways
NAD+ activates sirtuins — cellular maintenance proteins regulating inflammation, mitochondrial function, and longevity pathways.
Imai & Guarente, Trends in Cell Biology, 2014
06 . Why Jia formulated it this way
Jia
Estalife Founder
Certified Nutritionist since 2018
[100% Singaporean Family-Owned Factory]
I actually made this product because my parents are absolutely obsessed with NMN supplementation and have been long term users. Frankly it wasn't on my urgent launch radar until I saw the prices of NMN on the market. We've always been working with NMN as manufacturers with minimal markups just to cover manufacturing margins, and seeing them sold up to 50x the manufacturing cost didn't sit right with me - I strongly believe that nutrition should be made affordable and not paywalled.
We designed each dosage with 2 capsules to make 500MG, as a easy way for consumers to step down to 250MG (the minimum effective dose), or 750MG as needed. And after NUS found over 80% of NMN products in Singapore had lower NMN detected than label claims, I personally made sure our NMN is rigorously tested by third-party labs, Eurofins and SGS, to uphold product quality.
Thank you for all your love so far!
07 . Most NMN in Singapore isn't what the label says
80%+
NUS Medicine tested 18 NMN products sold in Singapore (2024). Over 80% contained less NMN than claimed — 3 had zero detectable NMN. Independent lab verification isn't optional.

08 . What to expect — a realistic timeline
NMN isn't a stimulant. It works at the cellular level. Here's what the research says about when effects become measurable.
Days 1–7
Absorption and conversion begins
NMN metabolites(2-PY, 4-PY) detectable in plasma within 5 hours of ingestion. NMN itself is rapidly converted — foundation stage, no noticeable effects yet.
Irie J, et al. Endocr J. 2020;67(2):153–160.
Weeks 2–4
NAD+ measurably increases
Multiple studies confirm significant blood NAD+ elevation within 2-4 weeks. Some notice improved energy and clarity.
Okabe et al., Frontiers in Nutrition, 2022
Yi et al., GeroScience, 2023
Christen et al., Nature Metabolism, 2026
Weeks 4–8
Functional shifts emerge
At 500mg/day, blood NAD+ elevation levels elevate by 2 times the baseline by week 8. RCTs report significant improvements in walking speed, reduced drowsiness, and better sleep quality at 6–8 weeks. Physical function scores improve vs placebo.
Kim et al., Nutrients, 2022
Igarashi et al., npj Aging, 2022
Individual results vary. These timelines reflect published clinical data — not a guarantee. NMN is a supplement, not a drug.
09 . How to take it
2 capsules daily. Simple. Consistency is what makes the research work — not timing tricks.
2
Take at the same time each day. Building a habit matters more than the perfect timing.
3
Give it at least 4 weeks before evaluating. NAD+ works at the cellular level — changes are gradual and cumulative.
If you are on medication or have a medical condition, consult your doctor before adding any supplement.
