Most supplements aren't what the label says

  • NUS tested 18 NMN products sold in Singapore. Over 80% were not what they claimed.

    In 2024, researchers at NUS Yong Loo Lin School of Medicine and Temasek Polytechnic bought 18 NMN supplements on the Singapore market and measured what was actually in them. More than 80% contained less NMN than the label claimed. Three contained no detectable NMN at all.

    What that means for you: in this category, price tells you nothing about whether the product is real. An independent lab result is the only thing that does.

  • US researchers tested 25 melatonin gummies sold for sleep. Nearly 9 in 10 were not what they claimed.

    In 2023, researchers from Harvard Medical School and the University of Mississippi bought 25 melatonin gummy products on the US market and measured what was actually in them. 22 of the 25 were labelled inaccurately, with melatonin ranging from 74% to 347% of the stated dose. Only 3 came within 10% of the label. One contained no melatonin at all, just CBD.

    What that means for you: the dose on the label is a promise, not a measurement. You could be taking a fraction of what you paid for, or more than three times it. An independent lab result is the only way to know.

What we test and how often

Microbial & heavy metals

Every single batch we manufacture is tested by Eurofins Singapore for microbial safety and heavy metals before it is released for sale.

Laboratory: Eurofins Singapore

Raw material purity

Every lot of raw material is tested before it enters production. Our NMN returns greater than 99.99% β-NMN content.

Laboratory: SGS

Finished product content verification

Eurofins measures the actual NMN content in the finished capsule and confirms it delivers the stated 500mg per serving. This is the test almost nobody in the category runs, because it is expensive and because it is where underdosed products get caught.

Laboratory: Eurofins Singapore

Affordable, because there is nobody between us and you

  • The usual chain

    Manufacturer, then brand owner, then distributor, then retailer, then you. Retailers typically take 40 to 50%. Distributors take another 20 to 30%. Every layer is priced into the bottle before it reaches you.

  • Here at Estalife

    We manufacture it and we sell it. There is no brand owner paying us a manufacturing fee and no retailer adding margin on top.

  • What we did not cut

    Same raw material grade, same NSF GMP certified facility, same Eurofins and SGS testing, same processes and machines used for the hospitals and global brands we manufacture for.

Singapore's largest NSF GMP-certified supplements factory

Our Ang Mo Kio facility manufactures for hospitals and global brands, and now for Estalife directly — no middlemen. You're welcome to see it for yourself.

Plant Glucosamine + Chondroitin + MSM: Together they support joint comfort and mobility.

Frequently asked questions

Kitchen turmeric is for flavor, not health. It contains very low levels (approx 3%) of active Curcumin. You would need to eat spoonfuls of powder daily to get the benefit of one Estalife capsule, which uses a 4:1 extract technology.

Many brands add black pepper because they use weak, raw turmeric powder that is hard to absorb. Because Estalife uses a Concentrated Extract, we deliver a high load of bioactive compounds directly, reducing the need for additives that can sometimes irritate the stomach.

Yes! That is the Estalife advantage. Our concentration technology allows us to pack the equivalent of 1,500mg of herb into a single capsule. We save you the hassle of swallowing multiple pills.

Yes. It is a natural, drug-free herbal supplement designed for daily joint maintenance.

While some feel relief in 2 weeks, we recommend consistent use for 4 to 8 weeks to allow the anti-inflammatory benefits to build up in your tissues.

Think you can trust supplement labels? Think again.

A supplement label tells you what a brand says is inside. It can’t tell you whether that’s true.

In many markets, including Singapore, supplements aren’t independently checked against their labels before they’re sold. That’s why, when scientists test supplements against their labels, they keep finding products with far less, far more, or none of what’s claimed.

It doesn’t work for my trigger finger inflammation so I tried another brand Nova Pro Flex which is more effective.
