Ambrosia Mental Jewels Review

Mental Jewels is a nootropic supplement by Ambrosia (headed by Mike Rashid) which is designed to enhance focus, attention, cognitive function, and perceived energy levels.  It is slightly stimulatory, but the benefits are not overly dependent upon Caffeine…

Mental Jewels Claims

As mentioned above, Mental Jewels is intended to:

  • Enhance Cognition & Memory
  • Improve Focus
  • Increase Mental Energy Levels

This isn’t some stim-bomb that’s going to jack you up like a pre-workout or some of the more stimulant heavy fat-burners.  No, Mental Jewels has much more of a Nootropic vibe, with only a small amount of mental stimulation.

If you watch Mike’s videos on YouTube, you’re aware that the term “Mental Jewels” is what he uses to refer to those bits and pieces of useful, practical advice that he drops here and there.

So, we feel the name Mental Jewels is pretty fitting for a supplement’s designed to improve how your brain works.  The only question, of course, is…

Does it work?!

Well, as with any supplement, the only way to tell is to breakdown each ingredient in order to:

  1. Gain a solid understanding of what each one does
  2. Determine if Mental Jewels contains the right amount

So, let’s just get into it, shall we?

Mental Jewels Ingredients

Mental Jewels contains 8 active ingredients, the doses of which are all transparently displayed on the Supplement Facts panel, making it super easy to do our job…Thanks Mike!

Siberian Ginseng

Siberian Ginseng, also known as Eleutherococcus senticosus (Eleuthero for short), is an adaptogenic herb which has been used for many years in traditional medicine for general cognitive support and stress-reduction.

Research supports the role of Eleuthero as an adaptogen which gives it a wide array of potential benefits.

Although the Mental Jewels formula is not inherently geared toward enhancing physical performance, Eleuthero has been shown to reduce susceptibility to fatigue in physically active subjects thereby making it an effective performance enhancement agent as well.

Mental Jewels contains 800mg of Eleuthero extract, a highly effective (clinical) dose.


Cordyceps is a type of Mushroom which has been used traditionally (not so much clinically) to counter fatigue and improve endurance.

Preliminary studies in animals support these stated benefits, but there hasn’t been much human research conducted upon which to draw conclusions.  In fact, Cordyceps has actaually failed to improve endurance in trained cyclists.

Of course, dosing could very well be the difference, but still, findings like this certainly don’t lend credibility to the notion that Cordyceps can ehance performance.

So, in the context of Mental Jewels, we’d still consider Cordyceps to be a pretty speculative ingredient.

Bacopa Monnieri

Bacopa Monnieri, like Siberian Ginseng, is an adaptogen, meaning it has the capacity to reduce the impact of stress, both physical and mental.

Of all the adaptogenic herbs out there, Bacopa has been one of the most extensively researched in humans, and studies indicate that it can be very effective when dosed appropriately.

The clinically effective range for Bacopa is anywhere from 200-500mg daily, depending on standardization.  Mental Jewels contains 250mg of a patented Bacopa extract known as BaCognize.

Alpha GPC

Alpha GPC is a highly bioavailable source of Choline and is considered one of the most effective supplements for increasing Acetylcholine levels in the brain.

Acetylcholine, for those unfamiliar, is a neurotransmitter in the brain which is heavily involved in various aspects of cognitive function such as memory-formation, attention, and the “mind-muscle-connection”.

While most of the research on Alpha GPC has been conducted in subjects with certain mentally impairing diseases (such as Dementia/Alzheimer’s), it is certainly the most potent of the Choline pro-drugs and therefore the most likely to convey cognitive benefits in more or less healthy individuals.

Mental Jewels contains 150mg of Alpha GPC per serving, not the most effective dose but still potentially effective to some degree.

Caffeine (from Infinergy)

Caffeine, as most of our readers are probably well aware, is capable of increasing perceived energy and alertness.  It accomplishes this by triggering the release of Noradrenaline, a neurotransmitter involved in the fight or flight response, and is quite reliable at doing so.

Mental Jewels contains a patented extended release form of Caffeine known as Infinergy which is alleged to reduce the likelihood of the dreaded “crash” due to slower absorption.

With 100mg of Caffeine per serving, Mental Jewels isn’t likely to cause negative side effects associated with too much Caffeine, but may provide non-habitual Caffeine users with a fair amount of energy.

Those used to taking higher doses of Caffeine (such as in pre-workouts or strong Coffee) may not notice much of a difference with this dose.


Glucuronolactone has become a popular ingredient in energy drinks and detox supplements due to the perception that it is somehow beneficial when it comes to supporting “natural” energy levels but, to be fair, there really isn’t much in the way of research to support this.

In the context of Mental Jewels, Glucuronolactone is probably pretty useless, but it certainly doesn’t hurt the efficacy of the formula.


p is a major component of cell membranes and is found in particularly high concentrations in the brain.  It is heavily involved in cognitive function and supplementation has been used successfully to combat cognitive decline in elderly subjects and those with disease states characterized by reduced cognitive function.

Phosphatidylserine has also been shown to effectively reduce stress, as measured both subjectively (self-reported) and objectively (biomarkers) at doses ranging from 60-600mg daily.

It is considered a safe and effective supplement for stress reduction but is not likely to produce any sort of notable cognitive improvements in normal healthy subjects.

Mental Jewels contains 50mg, not a particularly effective dose.

Huperzine A

Huperzine A is an Acetylcholinesterase inhibitor, meaning it blocks the enzymes responsible for the degradation of Acetylcholine.  Recall from above that Acetylcholine is involved in various aspects of cognitive function, so by reducing the breakdown of it, cognitive function can improve.

Of course, as with most Acetylcholine-boosting molecules, Huperzine A will tend to be more effective in individuals with lower than normal Acetycholine levels, but it can certainly “support” cognitive function in healthy individuals.

Mental Jewels Ingredient Takeaway

Mental Jewels contains the right ingredients (at the right doses) to subtly improve brain function.  The impact of such a formula isn’t going to be immediately noticeable for most people (except for a little Caffeine rush if you’re a light-weight), but over time it’ll become more and more noticeable.

Some of the ingredients are a little on the speculative side, meaning they don’t have studies to back up the claims that are being made about them, but the overall formula is solid.

Definitely one of the better Nootropic supplements available.

How To Take Mental Jewels

Mental Jewels is designed ot be taken just prior to “the most mentally demanding part of your day”, but it’s worth mentioning that the benefits associated with most of the ingredients (aside from Caffeine) tend to manifest and become apparent over a couple weeks to a couple months.

Those individuals expecting some sort of instant cognitive boost may be disappointed as Mental Jewels certainly falls in the category of Nootropics as opposed to Energy supplements.

Because the benefits take time to become apparent, consistency is important.  You have to take it every day, not just on the days when you stuff to do.

Where To Buy

Mental Jewels can be purchased from:

We’re a bit surprised to see that Mental Jewels isn’t available at more retailers, but given that many supplement companies are trending towards a more centralized, direct-to-consume business model, it actually makes sense.

The Bottom Line

As far as nootropics go, Mental Jewels may be moderately effective.  Some of the more promising ingredients may be under-dosed on a per serving basis, but taking two servings or more per day is safe given the relatively low level of Caffeine.

Will it make you Superman?  No, but it’s not supposed to!

Mental Jewels is just designed to encourage optimal mental performance throughout your day.  But as a way to support general cognitive function and encourage productivity, it’s not too shabby. exists to educate the supplement community and seperate the science from the hype.
