About & Methodology

Buying supplements is confusing. Every label makes big promises. Some products hide how much you actually get. Others cost a lot but work no better than cheap ones.

It’s hard to know what’s worth your money. That’s why Five Stars Lab is here.

We read the labels, look at the science, and give every product a clear score using the same simple system. So you can see what’s good and what’s not.

What we do (and what we don’t)

We look closely at supplements and give each one a score. Right now we focus on supplements for skin, hair, and nails.

We don’t sell anything, and no brand can pay us for a better score.

For every product, we check five simple things: what’s in it, whether the science backs it up, if there’s enough of it to actually work, how clear the label is, and if it’s worth the price.

How we score

Every product gets a score out of 10 on each of these five points:

  1. Does it work? We check if real studies show the ingredient does anything, and if there’s enough of it to matter.
  2. Is there enough in it? Some products use tiny, useless amounts. We make sure the dose is big enough to actually help.
  3. Is it clean and tested? We look for products checked by an outside lab for things like heavy metals, so you know it’s safe and the label is true.
  4. Is the label honest? Some brands hide how much of each ingredient you get. We reward the ones that tell you everything.
  5. Is it worth the money? A high price doesn’t mean it’s better. We look at what you pay for a dose that actually works.

Then we add it all up into one final score. Everything is out in the open, so you can always see why we gave a product the score we did.

Our promises

Trust is the most important thing here. So we promise:

  • Some of our links earn us a small commission if you buy through them. That never changes a product’s score.
  • When a popular product is weak, we say so.
  • We always tell you which links earn us money.
  • We only say what the science backs up. If the proof is weak, we tell you.
  • We’re not doctors, and we never promise to cure anything. We rate products, not your health.

Who’s behind it

Five Stars Lab was started by Ugnė, who studied biology and medical genetics and has worked in the supplement industry. That background means we know the marketing tricks and the cheap shortcuts that most shoppers never get to see.

We got tired of watching brands make big promises while selling weak products at high prices, and we know how hard it is to pick the right one.

So we score every product the way we’d want it scored if we were the ones buying it. Clear, careful, and based on what’s really inside.

A note about health

We go by what the evidence shows. Supplements are not medicine, and they are not meant to treat, cure, or prevent any illness. Always talk to your doctor before you start something new, especially if you’re pregnant, breastfeeding, or taking other medicine.
