Prevagen vs Dynamic Brain - Which Brain Supplement is Better?

Here’s our Prevagen vs Dynamic Brain face-off. Read on to learn which nootropic supplement is better for your memory, focus, and general cognitive functions, as well as how they compare to other OTC brain supplements out there. Short on time? Here’s a quick summary of our report.


Between the two, Dynamic Brain is the better option. While both are 100% natural supplements, Dynamic Brain contains far more ingredients (35+ versus Prevagen’s 2), and the ingredients themselves have more evidence backing their effectiveness for brain health.

Prevagen’s key ingredient, Apoaequorin, isn’t proven to work as there’s a lack of studies behind it – and the studies we do have were funded by Prevagen’s makers.

But while Dynamic Brain is the winner here, it’s far from a perfect supplement. Most of its key ingredients are stuffed in a proprietary blend, preventing us from seeing their doses and if they’re effective. For the price, there are definitely better options available on sale today.

Prevagen vs Dynamic Brain: About the Products

What is Prevagen?

Prevagen is a highly popular, all-natural dietary supplement made by Quincy Bioscience, from Wisconsin USA.

Prevagen consists of vitamin D and a ‘special’ ingredient called Apoaequorin, which is a jellyfish protein.

Prevagen’s manufacturer says that Apoaequorin, in combination with vitamin D, will give you:

  • Improved memory
  • Enhanced recall & information processing
  • Offset normal or mildly impaired cognitive function

The recommended dosage for Prevagen is 1 small, easy-to-swallow vegetarian capsule every day, with or without food.

Quincy Bioscience goes on to say that Prevagen has been shown in clinical research to improve the cognition of older participants.

The study participants were over 40 years old and took the recommended dosage for Prevagen, which is 1 capsule daily for 3 months, and saw positive results. We’ll get back to this study shortly.

For now, though, we must note it’s important to take some of these claims with a grain of salt. Why?

Because Prevagen has been causing a lot of controversies online. Its manufacturers, Quincy Bioscience, have been sued by the New York’s Federal Trade Commission (FCT) for making “false marketing claims”.

Obviously, not a great start for Prevagen. We’ll see if its claims are really grounded in science when we check the ingredients below.

But first, let’s go ahead and check Prevagen’s competitor – Stonehedge Health Dynamic Brain, to see how it differs from Prevagen and what its claims are.

What is Dynamic Brain?

Dynamic Brain is a dietary nootropic supplement made by Stonehedge Health, a growing company from California USA.

According to Stonehedge Health, Dynamic Brain is formulated to give you:

  • All-around brain health support
  • Maximize memory & focus specifically
  • Improve mental clarity

Just like its competitor, Dynamic Brain too is a 100% natural supplement and is vegetarian-friendly, gluten-free, non-GMO, and free of harmful synthetics.

The recommended dosage is 2 capsules once per day, 20-30 minutes before one of your meals.

So, how does Dynamic Brain compare to Prevagen in terms of effectiveness, safety, and value for money? Can it really improve your focus and brain function? We find out below.

Prevagen vs Dynamic Brain: Ingredients

The ingredient formulas of Prevagen and Dynamic Brain are completely different. Prevagen only has 2 ingredients, while Dynamic Brain has over 35.

When you look beneath the surface, though, neither one looks too impressive. Even though Dynamic Brain has many more ingredients than Prevagen does, it lacks in some crucial areas that make it fall behind other options on the market.

See for yourself.

Prevagen’s Formula

Prevagen contains the following ingredients, as shown on the label:

  • Vitamin D (2,000IU)
  • Apoaequorin (10mg)
Prevagen Ingredients Label & Information

Vitamin D is an ingredient most of us are familiar with. It’s a compound produced by our body when in contact with direct sunlight. We can also get vitamin D from foods such as fish or fortified cereals.

Vitamin D has many important functions in your body, including maintaining healthy brain function and mental well-being.

However, the 2,000IU of vitamin D is too light of a dose to make a difference. Unless you’re severely deficient, you probably won’t notice a substantial difference in your mood or cognitive function from vitamin D alone. (study review:

That said, vitamin D isn’t the main star of Prevagen anyways. The key secret to Prevagen’s benefits is supposedly Apoaequorin, the other ingredient in the formula.

What is Apoaequorin? It’s a protein from a certain species of glowing jellyfish.

The main idea behind Apoaequorin is that it helps clear excess calcium from your brain cells, reducing the “plaque build-up” as you get older. This results in improved memory and cognitive processes, according to Prevagen’s manufacturer.

However, this interesting speculation is nothing more than that – speculation. Apoaequorin only has a few studies showing it may help support your brain performance.

But if you dig a little deeper, you’ll find out that the main study that the manufacturer and others who promote Prevagen quote is actually sponsored by none other than – Prevagen’s manufacturers themselves! As a result, any findings from this study should probably be taken with a grain of salt.

So then, you’re essentially left with just one ingredient in Prevagen that works – vitamin D. The same ingredient you can find for far cheaper at your local department store.

All things considered, we don’t think Prevagen is a good brain health formula. It is missing many of the best ingredients we often see in the market-leading supplements.

Dynamic Brain’s Formula

Stonehedge Health Dynamic Brain is the complete opposite of Prevagen. Whereas Prevagen only has 2 ingredients, Dynamic Brain has a whole palette of vitamins and minerals, plus a proprietary blend full of herbal extracts and other interesting ingredients.

However, the issue with Dynamic Brain is that most of its key ingredients are contained within a so-called “proprietary blend.” It doesn’t show the ingredient’s individual doses on the label; you can only see the total dosage of the mixture.

Here’s how it looks:

Dynamic Brain Ingredients

Essentially, you can only see the doses of vitamins and minerals in Dynamic Brain. As for the rest, it’s impossible to tell if they work and are safe since we can’t see their dosages.

The best ingredients in Dynamic Brain include Phosphatidylserine and Bacopa – both are known to promote long-term memory formation. However, since their doses are hidden, we can’t tell if they are at all effective.

Another issue with Dynamic Brain is that it uses Huperzine A. While this ingredient is excellent for improving short-term memory and focus, it needs to be cycled on and off every few weeks. Continous use of Huperzine A is known to lead to headaches and cognitive impairment (ironically).

As for the vitamins and minerals in Dynamic Brain, you can get the same effect for cheaper from a multivitamin formula.

Our thoughts on Prevagen vs Dynamic Brain’s ingredients

When it comes to effectiveness and quality, any of the current best-rated brain health supplements would blow Prevagen’s and Dynamic Brain’s formulas out of the water.

If we had to pick between the two though, we’d definitely go with Dynamic Brain’s ingredient formula. It at least contains more vitamins and minerals that may contribute to your overall wellness.

Prevagen vs Dynamic Brain: Side Effects

Prevagen is unlikely to cause you side effects. It only has 2 ingredients – vitamin D and Apoaequorin, which is a jellyfish protein. Both ingredients are generally shown to be safe and they come in low doses so the risk of side effects is extremely low.

What about Dynamic Brain? Although it’s certainly more effective with its wider palette of ingredients, it also comes with an increased risk of side effects. There are over 35 active ingredients in the formula, many of which dosages aren’t shown for. Ingredients like Huperzine A can cause headaches, insomnia, and cognitive impairment if not taken a break from every once in a while. With that being said, many user reports of Dynamic Brain show it’s safe and side-effect-free for most healthy people.

If you’re concerned about side effects, your best bet is to talk to your doctor before taking a new supplement.

Prevagen vs Dynamic Brain: Customer Reviews

Since both Prevagen and Dynamic Brain have an incredibly high number of positive user reviews, it’s difficult to say how many of those are legitimate and how many are paid testimonials.

Considering the marketing power of supplement companies, it’s not too hard to fake reviews nowadays in order to increase the product’s rating. As a result, the best way to gauge how the product will work for you is by checking the ingredients for yourself, and seeing what science says about them.

Pricing & Availability

Prevagen costs $39.95 for 30 capsules of the Regular Strength Version. The Extra Strength version is far more expensive, but as we said, it’s not worth the price as the only difference is the dosage of Apoaequorin, an ingredient that isn’t even proven to work! You can buy the product on the official website and from many retailers online.

Dynamic Brain comes in bottles of 60 capsules and costs between $49.95-$53.99 depending on where you buy it. It’s available on the official website as well as on Amazon.

Final Verdict

Prevagen vs Dynamic Brain: which is better?

The answer is Dynamic Brain, but, ultimately, neither one lives up to the claims made by their manufacturers.

Dynamic Brain has more ingredients than Prevagen, and as a result, it provides a wide range of potential benefits. Prevagen only contains vitamin D and Apoaequorin, the latter of which isn’t proven to have any benefit.

Despite being the winner of this particular comparison, Stonehedge Health Dynamic Brain is far from a good nootropic supplement. It contains a proprietary blend which prevents us from knowing if its ingredients work at all.

If you want something that is safe, healthy, and effective that will help boost your concentration, memory function, and productivity, there are definitely better options available on the market.
