Dynamic Brain Review & Results

Dynamic Brain Supplement Review and Testing

By Richard Davidson, October 20 2025

What Is Dynamic Brain?

Dynamic Brain is Stonehenge Health’s flagship nootropic. Stonehenge is a small outfit that sells a handful of targeted supplements, and this one is pitched as an all-rounder for brain health, better memory, smoother word recall and general cognitive support.

I’ve gone through the label ingredient by ingredient, checked what the research says about each one, and used the product myself. The goals it sets are reasonable for a brain supplement, but I’m not convinced the formula, as dosed, can fully deliver on those promises. I’ll break down where it looks solid and where it falls short.

Key Points

I experienced only a minor improvement in focus with Dynamic Brain, the brand's promises to improve memory, recall and learning weren't perceivable during my test period.
Dynamic Brain purposely hides the amounts of each ingredient included in its product. This intentionally aims to obfuscate any analysis of its effectiveness. This lack of transparency raises a red flag.
Dynamic Brain uses a reasonably broad range of ingredients, but many ingredients are underdosed compared to the amounts shown to be effective in clinical studies.
Despite the inclusion of some proven nootropic ingredients (albeit underdosed in many cases), many more proven nootropic ingredients are missing from Dynamic Brain's formula.
A much more effective and proven alternative is ThinkEase. It's the top performing brain supplement for focus, memory, learning and productivity in my testing. I also like its scientific backing and clean label formula.

How Does Dynamic Brain Work?

Dynamic Brain makes a number of claims about its formulation and its effectiveness as a brain supplement. Unusually Dynamic Brain makes a point if using 40 different ingredients. Superficially this sounds persuasive and many proven nootropic ingredients are present (though many appear underdosed), but critically, many of the ingredients used aren't widely regarded as having substantive benefits for the brain. The ingredients which have potential to be beneficial (when dosed correctly) include Bacopa Monnieri, Huperzine A, Phosphatidylserine and Choline. Bacopa Monnieri is considered effective in improving memory acquisition, helping in the retention of information, as well as helping moderate or reduce anxiety [1]. Phosphatidylserine is also widely regarded as being capable of providing memory support, particularly in older adults with memory impairment. It works by aiding neuronal membrane function and signaling [2].

Huperzine A is a proven nootropic which works by inhibiting acetylcholinesterase, which can help increase acetylcholine. It's been fairly widely studied as a potential support for individuals diagnosed with Alzheimer's disease, but may have benefits for healthy individuals. However, Huperzine A shouldn't be taken on a sustained basis, this alone raises concerns over on-going supplementation with Dynamic Brain [3].

Turning to Choline, the science is clear, as it's known to be a precursor for acetylcholine, which is fundamental for both memory and muscle control. However, Choline is inferior to Citicoline where the data is much more compelling [4]. Nonetheless, Choline is considered beneficial despite being an inferior form, as it's fundamental for brain function. It's also worth mentioning the DHA (Docosahexaenoic Acid), a an Omega 3 fatty acid, is a worthwhile addition to Dynamic Brain, as several pieces of research support it being beneficial for long-term brain health.

Despite these superficially worthwhile additions, much of Dynamic Brain's modest serving size is given over to ingredients where the science is far less supportive [5]. Some ingredients it's fair to say may have some modest brain benefits, but the science is unclear. Ingredients in this category are DMAE (Dimethylaminoethanol) Bitartrate, Inositol, Boron, Vitamins (A, B-Complex, C, D, E) and Minerals (Calcium, Iron, Magnesium, Zinc, Selenium, Copper, Manganese, Chromium, Molybdenum, Potassium) [6],[7],[8].

Beyond this, Dynamic Brain uses a wide range of ingredients which simply aren't really considered to have any meaningful brain benefits. L-Glutamine HCl, Glutamic Acid, Bilberry Fruit Extract, Grape Seed Extract, Grapefruit Seed Extract, Olive Leaf, Cinnamon Bark Extract, Licorice Root Extract and Vanadyl (Vanadyl Sulfate) simply don't support cognitive performance or brain health in any meaningful way. Their inclusion in Dynamic Brain is baffling. Perhaps they constitute an impressive looking list, which in turn enables Dynamic Brain to claim to use 40 different ingredients, which is true. But if those ingredients play no meaningful role in delivering the product's claimed benefits we have to question how straightforward the brand is being with its customers. These ingredients seem to be present to form a marketing story, rather than make a meaningful difference to the brand's customers lives.

Scientific Basis

Dynamic Brain doesn't cite any clear research into the product's effectiveness as a brain supplement. Instead the brain emphasizes a claim from one of its ingredient suppliers, BacoMind. This research is challenging to locate. One study is accessible but only focuses on ingredient safety, rather than effectiveness and the dosage tested doesn't match that used in Dynamic Brain [9]. The branded nature of this ingredient sounds impressive, but in reality it's simply a name given by the ingredient supplier to their standardized Bacopa Monnieri extract - in other words the ingredient has a standard level of active bacosides - the main bioactive compound in Bacopa. One study suggests it's effective in inhibiting some enzymes (COMT, PEP, PARP) as well as in blocking serotoin receptors (5-HT6, 5-HT2A), which in turn may support memory function, but critically this research was conducted in vitro, rather than as an oral supplement, the results therefore can't be applied to Dynamic Brain, but the brand seems to make this misleading link - however the brand's website doesn't explicitly link to the research, rather is includes a static image of a superficially persuasive graph and video [10].

Beyond Dynamic Brain's claims relating to BacoMind, no other research or claim support is offered. As I've explained, the vast majority of the ingredients in Dynamic Brain appear to be either underdosed or of limited or no benefit for brain health and cognitive performance.

Qualitative Review of Dynamic Brain's Efficacy

Despite my reservations about Dynamic Brain's ingredient list and a number of ingredients I was uncertain about trialing, I did elect to test the product directly myself. The 2 capsule daily serving size was simple enough to manage, but I felt somewhat uncomfortable knowing that the product includes undisclosed amounts of many ingredients, a large number of which haven't been widely studied, their general effects and safety are in some cases unknown. However, my trial period progressed without any obvious negative consequences, from my test at least the product was tolerable and didn't lead to any adverse reactions or side effects.

In terms of efficacy, I wasn't able to observe tangible improvements in any of the areas cited by the brand, with one minor exception. I wasn't able to discern any clear improvement to my ability to focus, or indeed to my learning capability, despite there being ample opportunity in both my personal and professional life for the effects to be observed. The minor benefit I believe I may have experienced was a very modest improvement in recall. Whilst far less pronounced than more effective brain supplements, day-to-day recall of information felt slightly more fluid than normal, but I emphasize the word slightly. I have to put this down to the inclusion of Bacopa Monnieri, which could be present at the required 300mg level, but again I can't be certain about this due to Stonehenge Health's decision to hide the amounts of each ingredient used.

So, my experience was perhaps marginally better than expected, but it's important to emphasize that Dynamic Brain really doesn't compare to the best brain supplements I've trialed. It may lead to some modest improvements, but it's unlikely to perform better than a standalone Bacopa supplement.

Estimate of Efficacy Relative To Similar Products

Dosage:

Dynamic Brain has a two capsule serving size, sensible for the amount of active ingredients, but it is still likely that a proportion of the capsules' contents comprises filler materials (listed as silica and rice flour on the product's label). The total amount of active ingredients in Dynamic Brain is 947.2mg, which is reasonable, but someway short of the amounts used in the most effective brain supplements I've tested.

Quality:

I can't rate Dynamic Brain highly on this measure unfortunately. The use of a proprietary blend, a wide range of unproven ingredients and many scientifically proven ingredients missing is problematic. Added to which, the brand seems to overstate its effectiveness with potentially misleading claims and a lack of evidence to support its claims.

Efficacy:

Dynamic Brain didn't provide a substantial improvement in any of the areas claimed. I did observe a very modest improvement to memory recall, but this was very mild compared to more efficacious products I've tested.

Cost:

Dynamic Brain retails for $40.99 per bottle, which places it in the same bracket as more robustly formulated products. Unfortunately, I would consider it to offer less value for money than the best products available, due to its comparatively small serving size and limited benefits.

Safety Considerations and Potential Side Effects

Dynamic Brain's formula shouldn't cause adverse reactions in most people. However, there are a few points worth bearing in mind. Firstly, Dynamic Brain's ingredients aren't listed with clear amounts, meaning it's impossible to know how much of each ingredient you're consuming and what, if any negative effects might be expected. Secondly, Dynamic Brain's long list of ingredients includes a number of compounds that haven't been widely studied, it's therefore conceivable that unknown effects could be possible. Thirdly, Dynamic Brain declare on the product label that the product contains fish (namely tuna) and soy - both are allergens, meaning for some people the product should be avoided (tuna is however better tolerated than many other fish for most people). The inclusion of tuna makes the product unsuitable for vegans and other individuals that choose to avoid consuming fish.

Overall Assessment

I can't recommend Dynamic Brain as a product that's likely to lead to meaningful improvements, or even a basic level of support, for people looking to improve their cognitive performance or better manage symptoms of cognitive slow down or decline. There is some potential for Dynamic Brain to aid in recall, but this is likely down to a single ingredient, Bacopa Monnieri, which is present in the vast majority of better formulated products. The use of ingredients in insufficient amounts, the use of an intentionally opaque ingredients list and a long listed of unproven ingredients simply doesn't work as well as more science led formulas.

If you're looking for a brain supplement that's robustly formulated, whether it's to improve memory, learning or productivity, my current recommendation is ThinkEase. It also includes Bacopa, but uses many more proven nootropic ingredients that work well in delivering meaningful and perceivable cognitive improvements.
