Welcome to SupplementsTested.com

Supplements Tested is an independent review site that provides the information you need to make the best buying choices.

We analyze what matters – the product claims, ingredients and the companies behind the supplements to help you cut through the marketing hype.

We Started this Site to Help People Like You

When we started this site back in 2013, it was intended as a useful resource for friends and family who were into health, fitness and bodybuilding – but we now have readers all over the world.

And when you think about how big the supplement industry is and how much garbage there is out there, it’s clear websites like this one need to exist.

We Think You Deserve Better

You’re here because you’re looking for supplements to improve your health, fitness, or physique – that’s awesome. And achieving your goals should be a lot easier than it is. If only there were supplements you KNEW did the job you were paying for.

But it can all be so confusing.

While one marketer claims they’ve hit upon a new ‘miracle’ ingredient, another tries to discredit it to hawk their own trash.

Let’s face it…

The supplement industry is packed full of snake-oil salesmen looking to rob you of your cash.

And if you think we’re overstating the issue, do a little digging for yourself. You’ll be shocked to learn how many products contain unproven, disproven, or even unsafe ingredients.

Say no to hidden formulas

We’re on a crusade to ban proprietary blends. These sub-formulas display ingredients but hide vital dosage info.

Some marketers will tell you their products use proprietary blends to protect their ‘revolutionary formulas’. But in reality, this is just a ruse to hide too-low dosages, poor research and weak formulas.

Don’t believe the hype.

But there are good supplements out there – you just need to know where to look.

And that’s where we come in…

What to Expect from Supplements Tested

Using the most up-to-date science, we test the latest supplements and write honest reviews.

For your benefit, we’re into facts – and we don’t do hype.

Of course, we have our own opinions. But as much as possible, the statements we make have science behind them – and we provide links to the relevant publications to prove it.

But how do you know which supplements to use?

Pinning down the type of supplement you need is one thing, but finding the exact product that will work for you is another.

For every category of supplement there’s thousands of options out there all claiming that they’re the best for you.

But how do you choose between them?

Use this website.

At SupplementTester.com, we personally review supplements in every area of the market identifying which ones bring the benefits, and which ones are total bunk.

What do we look for in a supplement?

By extensive research and a wealth of professional supplement knowledge and experience, we analyse each product in several key areas to ensure that it meets our high standards.

Before we recommend a supplement we make sure that it:

  • Comes from a reputable company – Is it well known? Are they reliable? Any Guarantees?
  • A proven serving schedule – Does it have enough for that particular supplement?
  • Proven ingredients – Are there any studies behind them? Is there enough used?
  • Doesn’t use Proprietary Blends – No ingredients are hidden
  • Doesn’t have any side effects – Are there any negatives, are there any risks?

Only after a supplement passes these areas, only then do we feel comfortable recommending it.

What should you be looking for in a supplement?
