Alteril-Review

The search for sleep aids is nothing new; people have been taking medicines and  supplements to help sleep for years, even decades now. What is new is that people are increasingly looking for all-natural sleep aids. Powerful, habit-forming sleep medications are falling out of favor and other methods are growing more and more popular.

Alteril-Sleep-Aid

It’s fair to wonder how many of these natural sleep-aids really work, though. A lot of them haven’t been verified by the FDA, which doesn’t necessarily mean they won’t work, but it does mean that it can be difficult to sort out the ones that do from the ones that don’t. In this article we’ll be taking a look at Alteril, a sleep aid that claims to be the best, and we’ll you know whether or not it’s worth your money.

Overview: What is Alteril?

Think about how you feel after eating Thanksgiving dinner. That cozy, drowsy sensation that puts you right to sleep. We’ve all been told what causes it: tryptophan. Tryptophan is an amino acid, a type of protein. Turkey has a lot of it, and so does pumpkin. So naturally, after eating a big meal of turkey finished off with pumpkin pie, you’re going to sleep well.

Alteril is a sleep aid that uses tryptophan as the main ingredient. It has plenty of other ingredients as well, which we’ll discuss later on, but tryptophan is definitely the main one. Alteril claims to help you fall asleep faster and stay asleep longer, while promoting deeper sleep, as well.

Who is the manufacturer behind Alteril?

Alteril is made by Biotab Nutraceuticals. Biotab makes a few different supplements, like Extenze. Finding information about the company though, is nearly impossible. Their own website is no longer active, and a search of the company name brings up articles about various lawsuits, which is not a good sign. 

What are the ingredients of Alteril?

The list of active ingredients is long. Let’s start with melatonin. Melatonin can be found in many sleep aids, like Luna Gentle Sleep Aid, Nocturest, and Genius Sleep Aid. Among the melatonin in Alteril is also glycine, GABA, hops, L-Tryptophan, valerian root extract, passion flower herb extract, skullcap extract, chamomile, and soy. Inactive ingredients are dicalcium phosphate, povidone, sorbitol, crospovidone, stearic acid, magnesium stearate, and riboflavin. 

How does Alteril work?

Sleep-Pill

Alteril relies heavily on the melatonin and tryptophan. Melatonin is the hormone your body uses to regulate sleep. When it enters the bloodstream, you’ll fall asleep quickly and you’ll enjoy longer periods of deep sleep. As it leaves the bloodstream, your body begins to wake up. There’s 4mg of melatonin per pill, which is definitely a big enough dose to improve your sleep.

Tryptophan works a bit differently. It doesn’t affect your sleep directly; instead, it stimulates the production of seratonin, which in turn promotes better sleep. Seratonin stimulates the brain to put you to sleep and wake you up, and it also regulates your mood. Alteril has 666mg of tryptophan per pill.

The other active ingredients are a mixed bag. GABA is a neurotransmitter that can make you feel relaxed and drowsy, but it’s not absorbed well in the gut. It’s basically useless in this pill. Skullcap is an herb that’s long been used as an anti-anxiety treatment. It could help your sleep by reducing anxiety. Valerian root has been considered a very effective natural sleep aid for centuries, although that’s not a statement supported by the FDA. Likewise for chamomile. Hops are a mild sedative, although these pills couldn’t possible have a big enough dose for them to be effective. 

The valerian root might add something, but overall most of these ingredients are probably just here to back up the “all-natural” claim. Tryptophan and melatonin are doing the heavy lifting. Fortunately, they do it well. We wish they’d just take that stuff out, make it a tryptophan and melatonin supplement, and maybe lower the price since they won’t have all the other ingredients. 

That’s nit-picking, though. Alteril works, plain and simple. It uses powerful, well-studied, and all-natural ingredients that really do promote better, deeper sleep.

Safety and Side Effects

These pills are perfectly safe. Normally, anything with a proprietary blend should be treated with caution, since you can’t know the dosages of any of the ingredients. Fortunately, Alteril is sold at CVS, which has all supplements third-party lab tested, and posts the test results on the product pages online. It’s easy to see exactly how much of each ingredient is in each pill.

So, we can say that Alteril is safe to consume. All of its ingredients are well-known and natural, and all of them have been used in clinical trials and are not known to cause any dangerous side effects. It is possible that if you take too many pills at once that the tryptophan may cause some unpleasant digestive problems, so just be sure to follow the directions on the bottle.

Where to Buy and Cost

Alteril: Is it Worth It?

worth-to-buy

Yes and no. We don’t like the lack of transparency when it comes to the manufacturer, and it’s annoying that they’d list a bunch of herbal ingredients that are present only in such small doses that they’d have little to no effect.

That said, Alteril definitely contains effective doses of tryptophan and melatonin. We know that those are two powerful and all-natural sleep aids. There’s no doubt that Alteril will help you sleep. You can find melatonin supplements for less, but the combination of melatonin and tryptophan may be more powerful, and that might be worth the cost.
