Peptiva sleep supplement boxPeptiva is sort of a hybrid between a natural sleep aid and probiotic supplement. In my opinion, it’s more of a sleep aid since that part of the formula is stronger than the probiotic blend. Having classified Peptiva as a sleep aid supplement, I’m primarily going to review it based on its ability to help induce sleep.

We’ve reviewed a bunch of different sleep aid supplements here at, and I’ve personally written many of those myself. As someone who has struggled with Insomnia for a very long time, I’ve tried a lot of these natural sleep supplements and can often speak to my personal experience with them.

This is not the case with Peptiva specifically just because I felt the formula was too weak and ultimately not worth my money, so therefore have not tried it. Before I explain why I don’t recommend Peptiva, I’d strongly recommend you check out my top rated sleep supplements by clicking below…


Peptiva Benefits

Despite my opinion on the formula being relatively weak, there’s definitely some benefits to be had when supplementing with Peptiva. There are a good amount of nutrients in here that are generally believed to be effective in terms of helping people fall asleep. Here’s a list of the Peptiva benefits as listed on the bottle…

  • Renews digestive health
  • Multi-strain probiotic matrix
  • Guaranteed potency
  • Doctor formulated

Peptiva Ingredients

The analysis of the formula may not be very sexy, but it’s the most important part of every review we do. You can learn everything you need to know just by looking at the formula…that is, if you know what you’re looking at, which I do.

As a Nutrition & Wellness Consultant and long-time supplement analyst, I believe it’s safe to say I know what I’m doing when evaluating the formula of any given supplement. Let’s break down what I’m seeing with this Peptiva formula…

Proprietary Probiotic Matrix

The probiotic matrix contains 6 different active strains, which is pretty solid, but the potency of this matrix is what bothers me. There’s a total of 26 billion CFU per serving…I know that sounds like a lot, but it really isn’t when you compare it to other probiotic supplements.

The average probiotic supplement contains about 50-60 billion CFU, so Peptiva’s probiotic matrix is about half as potent as your standard probiotic supplement. This is why I decided to evaluate the supplement primarily as a sleep aid. I simply feel the probiotic blend isn’t potent enough for this to truly function primarily as a probiotic supplement.

GABA is an ingredient that is commonly used in natural sleep supplements due to its ability to enable the mind to relax. It’s also often used as an anti-anxiety supplement for that reason. Researchers believe that low levels of GABA can be linked to disrupted sleep patterns and insomnia. I love the dosage size as well at 100 MG per serving.

Valerian Root is potentially the most effective natural sleep aid ingredient out there in my opinion. That statement is debatable, but I personally have had great success with valerian root. Valerian root is a natural plant extract that has long been used for its sedative effects. This non habit forming, powerful, natural sedative is truly amazing.

With that being said, I do believe the dosage is a little bit low at 50 MG per serving. I’d ideally like to see it at about 100 MG per serving, but I do believe it can be effective at 50 MG nonetheless.

Melatonin is perhaps the world’s most widely used sleep aid ingredient, but typically if you’re using a melatonin supplement, you’re getting 5-10 milligrams per serving. For some reason, they have only dosed the melatonin in Peptiva at 1.5 MG total, 50% being immediate release and 50% being delayed release. I’m not sure why the dosage is so low, but it’s a good addition to the formula nonetheless.

Peptiva Reviews From Real Users

Peptiva does not appear to be sold on Amazon, which is generally my primary source for user reviews. However, I was able to find 87 Peptiva reviews submitted by users on GNC’s website. It received an average rating of 3.9 stars out of 5 across those 87 reviews.

3.9 isn’t a terrible average, but it’s not super impressive either. The good news is that the majority of the Peptiva reviews are positive…the bad news is about 20 people gave it 2 stars or less. The user reviews are overall pretty mixed, so there’s not a whole lot to go off of here.

I tend to rely more on my analysis of the label and personal experience with the supplement as opposed to reviews submitted by users, but I do like to add this section in just to gain some more perspective on the product and add another factor to my review.

The Pros

  • Includes valerian root and GABA
  • Received about 50 positive user reviews on GNC
  • Available in stores like GNC and Walgreens

The Cons

  • Probiotic blend is comparatively weak
  • The melatonin dosage is pretty low
  • Overall potency should be higher in my opinion
  • Didn’t rank amongst our top 5 sleep supplements

Peptiva Conclusion

The only element I wish I could add to this review is personal experience, but there’s a reason I haven’t tried the product…it’s just not potent enough for me to feel like it’s worth giving it a shot. I’ve tried a lot of sleep supplements, and I know this one wouldn’t work for me just based on the formula…

Does that mean it wouldn’t work for you? Not necessarily, but there are several sleep aid supplements that I would recommend way more strongly than this one. I do not feel confident recommending Peptiva based on the formula, but you should definitely check out my top ranked sleep supplements below.
