Prevagen vs Provasil: In this comparison, we’ll see which of these two natural brain supplements are safer and better at supporting your memory, cognitive function, and other aspects of mental performance.

Nootropic supplements like Provasil and Prevagen are used by more and more people to boost their mental capacities for work, studies, sports, and everyday life.

In other words, it doesn’t matter if you’re in your 60s or 20s – these brain supplements can really improve your quality of life, provided they work and have safe ingredients.

So, do Prevagen and Provasil work? How do they compare against each other? And where do they sit on our list of the best nootropic supplements? Our team finds out below.

Prevagen vs Provasil – The Basics


Prevagen Overview

Let’s start with Prevagen.

This is a memory supplement that comes in regular strength (10mg) and extra strength (20mg) capsules. Each bottle contains 30-60 capsules, depending on which version you buy.

If you like flavored pills, then you’ll be glad to know Prevagen offers chewable tablets too!

We’ve picked the top three nootropic stacks that are available to you right now for cognitive support.



Prevagen is originally produced by Quincy Bioscience, a company from Wisconsin USA.

We did a little digging into Quincy Bioscience and found out they were sued by the Federal Trade Commission (FTC) for making false advertising claims.

  • What were these claims, you ask? Well, apparently, Prevagen’s main ingredient, Jellyfish Protein, was marketed to do all sorts of wonders for your brain. And apparently, the FTC and a few other bodies thought these claims were not founded on science, and misleading to people. Some even argued that Prevagen is a total scam supplement.

However, what surprised us the most is that Quincy Bioscience runs the same controversial ads to this very day.

If you check their official website you’ll see some quite odd ads with jellyfish, which is the source of Apoaequorin, the main ingredient in Prevagen that is said to boost your cognitive function.

So, do Prevagen’s ingredients actually work? Or did Quincy Bioscience make a supplement that only has marketing going for it, but not real science? You’ll find out below in the ingredients section!

Provasil Overview

Provasil is a brain supplement specifically designed for older people who’re experiencing loss of cognition and memory.

However, the makers of this product say that it can also work for younger individuals, such as students who’re looking to improve their information retention.

  • Provasil comes in bottles of 60 capsules, and you’re meant to take 2 capsules with one of your main meals each day.

Sounds good, but does it really work?

Well, one thing we’ll tell you straight away is that Provasil at least boasts a decent reputation online! Unlike Prevagen, it has never been sued for misleading claims or anything like that!

So that’s good – Provasil wins in the brand trust department for sure.

Prevagen vs Provasil: Ingredients

In terms of ingredients, neither formula looks too impressive, but if we had to pick, we’d go with Provasil.

For one, Provasil has many more ingredients than Prevagen (15 vs 2). Secondly, the quality and effectiveness of the ingredients themselves are better in Provasil than Prevagen, as you’ll soon see for yourself.

Even though Provasil has some ingredients that are completely ineffective for brain health, it still uses a few decent nootropics that may aid your memory.

Prevagen, on the other hand, only has 2 ingredients, one of which is an underdosed vitamin, and the other is an unproven ingredient. See for yourself below:

Prevagen’s Ingredients – Prevagen vs Provasil

  • Apoaequorin (10mg) – Prevagen comes in two versions, “regular strength” 10mg and “extra strength” 20mg. It doesn’t matter much though, as Apoaequorin doesn’t do anything. (source: WebMD)

This fancy-sounding protein is extracted from glowing jellyfish. Quincy Bioscience has made claims that it can boost calcium signaling and remove plaque from your brain that is associated with neurodegeneration.

leading top brain supplements

However, the only studies we have on Apoaequorin were financed by Prevagen’s makers and were done by scientists whose work had been removed from PubMed in the past because of falsified results.

Based on this, we can’t recommend Apoaequorin as an effective brain ingredient.

  • Vitamin D (1,000IU) – Vitamin D is a good ingredient. A basic vitamin, but with many functions in the body and brain. It can boost your mood and make you feel livelier.

The issue is, it’s underdosed in Prevagen. Vitamin D optimal dose is at least 3,000-5,000IU per day to reap its therapeutic cognitive benefits.

Considering that you may not be getting enough vitamin D from direct sunlight (statistics show billion people are deficient), it’s crucial to supplement with higher amounts of this vitamin to ensure optimal health.

So vitamin D is a good choice in Prevagen for sure. But alone, it can’t do much! You’ll want to pair it with other proven brain ingredients to feel an impact on your cognitive function.

Provasil Ingredients – Prevagen vs Provasil

Within each serving of Provasil you’ll find:

  • Vitamin C – this is a general antioxidant, it helps reduce inflammation, but doesn’t offer much cognitive benefit.
  • Vitamin B9 – this is actually a good ingredient for older folks as it can reduce homocysteine, an amino acid that can clog up your small capillaries in the brain.
  • Vitamin B12 – similar effects as B9 in helping to reduce brain plaque, but it also helps boost mental energy if you’re deficient in it. A good choice!
  • Biotin – many of us already get plenty of biotin throughout the day so unless you’re a strict vegan, you won’t benefit much from this one.
  • Choline Bitartrate (150mg) – Choline is usually a good brain nutrient; it can feed your neurons and repair them, leading to better memory. However, the bitartrate form of choline is very cheap and has poor bioavailability, which means it can’t pass through your blood-brain barrier and exert any of its benefits.
  • L-Tyrosine (100mg) – Tyrosine can make you mentally more focused and sharper when you’re in stressful and cognitively demanding situations. However, you’d need to take at least 150mg, ideally 500mg of L-Tyrosine to notice its benefits. The 100mg found in Provasil is too low.
  • N-Acetyl L-Carnitine (100mg) – This is a brain antioxidant that can protect your neurons from damage. Good for older folks whose brains are starting to decline in function.
  • Bacopa (whole herb) (100mg) – This is a great memory ingredient, although it comes in a cheaper form in Provasil, and so it’s not as effective as, say, the Bacognize® patented Bacopa extract.
  • Ginkgo (leaf) (60mg) – Ginkgo is a good herb, but you’ll need more than what’s found in Provasil for it to work. Also, Ginkgo needs to contain precise amounts of terpenes/flavonoids in the right ratio (12% terpenes, 6% flavonols) to have an impact on your memory.
  • Phosphatidylserine (50mg) – PS is a brain nutrient that influences the fluidity and permeability of your brain cell membranes, resulting in better neuron to neuron communication. Sounds good, right? Well, it’s unfortunate that it’s another underdosed ingredient in Provasil!
  • L-Glutamine (45mg) – Glutamine is a common sports supplement because it can help with muscle recovery. But this is when taken in grams. At 45mg of glutamine per serving, it’s not enough to offer any cognitive benefit either.
  • Phosphatidylcholine (30mg) – PC has some similar benefits to Phosphatidylserine, but its YET another underdosed ingredient in Provasil.
  • Asian Panax Ginseng (30mg) – Some supplement manufacturers like to include a bit of everything to make it appear like it works. We’re afraid the same is the case with Provasil. Asian Panax Ginseng is a great mood-boosting ingredient, but 30mg is not even close to its effective dose.
  • Resveratrol (25mg) – Resveratrol is a powerful anti-aging antioxidant. It can help protect your cells from free radicals. Although you won’t necessarily feel it working, it’s a good ingredient if you want to help stave off some of those negative effects of stress and aging on the brain.
  • DHA (5mg) – DHA is probably the most effective nootropic ingredient in existence. If for no other reason, then because 60% of your brain’s fat is made of DHA. In case you didn’t know, DHA is an omega-3 fatty acid, however, you’ll need to take between 500-1,000mg of it daily to give your brain enough of a boost.

Our Thoughts on the Ingredient Profiles

Provasil wins for sure, but it’s far from a perfect supplement itself.

L-Tyrosine Nootropic Review


While it has more ingredients, and better ingredients, Provasil is still missing some of the most effective nootropics.

These include Lion’s Mane (brain repair), Citicoline (memory, cognitive decline), Vitamin B6 (mood, cognition) and a few other nutrients.

Vitamin B6 as a Nootropic


However, this is not the biggest issue with Provasil. The main problem is that it uses some great ingredients, but they’re underdosed – making them completely ineffective!

Still, compared to Prevagen’s formula which consists of Apoaequorin (which doesn’t work) and vitamin D (which is underdosed), Provasil easily wins in this department!

Prevagen vs Provasil: Side Effects

Prevagen, as ineffective as it is, shouldn’t give you any side effects. Vitamin D is dosed very lightly, and Apoaequorin hasn’t been shown to produce any adverse effects – it doesn’t produce any effects at all.

Provasil does come with a slightly higher risk of side effects, simply due to the sheer number of ingredients it uses.

However, the ingredients themselves are well studied for the most part, and come in relatively safe doses. So if you’re a healthy person, then neither Prevagen or Provasil should cause you any troubles!

Prevagen vs Provasil Customer Reviews

Prevagen is definitely the more hyped product between the two. It boasts tons of user reviews online, including on Amazon and other 3rd party sites. Some users are happy with it, others are not.

You can never tell which reviews are truly legitimate and which ones are based on the ‘placebo’ effect.

The same goes for Provasil’s user reviews.

This is why we always say it’s best to be your own judge, and to look at the research behind the ingredients. This is the surest way you’ll tell if the product is worth your money or not.

Prevagen vs Provasil Price and Value For Money?

Provasil costs up to $79.99 on Amazon, and around $46 on the official website. Obviously, you should do your research before buying this supplement to make sure you get it for the lowest price possible.

However, even for $46, it’s still an expensive supplement and not the best value for money considering many of its ingredients come in cheap, poorly absorbable forms.

Prevagen, on the other hand, costs around $40, depending on where you buy it. Considering that it doesn’t work at all, some will go as far as to say it’s a complete rip-off! We don’t blame them!

Prevagen vs Provasil Conclusion

So that concludes our Prevagen vs Provasil comparison.

While Provasil is a better supplement than Prevagen – it has more ingredients and also more effective ingredients – it’s still far from the best brain supplement we’ve reviewed.

It costs a ton, even more than some of the top-rated nootropics, despite using cheaper and less bioavailable ingredients than its competition.

As for Prevagen, it only uses 2 ingredients, one of which doesn’t even work, and the other being an underdosed basic vitamin. Safe to say this product is best left alone!
