This is our Alteril review. In this post, we’ll inspect this so-called ‘sleep aid supplement’ by checking its ingredients, benefits, side effects, dosage instructions, and more.

Alteril claims to help you with:

  • Sleep
  • Relaxation

It uses a dosage of 2 capsules per day and offers 30 capsules per package for about $15.

We are keen to inspect its ingredient profile to see whether it will help you sleep. This will ultimately tell us if it’s worth buying or not.

Let’s get straight into it.

Pros and Cons

Alteril is far from a bad product. It does have some great ingredients like tryptophan, which also uses an effective dosage.

But on the flip side, there are also a lot of ‘junk’ ingredients. As in, fillers that only increase the cost of this product, but not the benefits.

Plus, some users won’t like the price of $15 for just two-weeks worth of product.

With that said, here’s our breakdown the key positive and negative things about Alteril:


  • A great dose of melatonin
  • L-Tryptophan helps with sleep and mood, but needs to be taken on an empty stomach


  • Uses proprietary blends which prevent you from seeing ingredient doses in them
  • A few unproven ingredients
  • Lack of quality sleep aids like Montmorency tart cherry, magnesium, and theanine

About the Company

Alteril was founded by a company called “Biotab Nutraceuticals, Inc.”.

Since its inception in 2006, the company has been producing mostly natural health supplements and food products.

They appear to be based in the USA and ship worldwide.

We were a bit disappointed with the lack of information about the company, such as its history, how it all started for them, and what other products they sell. Their website also looks fairly outdated, which makes the whole experience a bit sketchy.
