1. X BASICS | GET THE BIG PICTURE

What is X?

X is the world’s most powerful brain supplement.*

It is a brain performance enhancer, meaning that it improves brain performance—especially focus, energy, attention, cognition and memory—through a unique combination of ingredients, each of which has a specific proven effect on the brain.*

X is a science-driven product, meaning that its formulation was based on results of rigorous research in neuroscience.

Where can I see the scientific research on the ingredients?

What are the benefits of X?

What was the basis for selecting the ingredients in X?

We included all ingredients for which all of the following were true:

  1. The ingredient has been proven in clinical trials to improve one or more aspect of brain performance.
  2. The ingredient has no significant adverse effects.
  3. The ingredient is listed by the FDA as Generally Regarded As Safe (GRAS).
  4. The ingredient is already taken by a large number of people in the U.S.
  5. Multiple anecdotal reports support the benefits and lack of adverse effects.

How was the amount per serving for each ingredient determined?

For each ingredient, we considered the following:

  1. Dosage range of ingredient used in clinical trials.
  2. Typical amount per serving in existing supplements already on the market.
  3. Amounts used in anecdotal reports.

We then conservatively set the amount per serving at the lower end of the range identified through these three sources.

How safe are the ingredients in X?

We use only the highest quality premium naturally-sourced ingredients.

All ingredients have been the subject of extensive clinical trials (research performed on humans).

The FDA lists all ingredients as Generally Recognized as Safe (GRAS).

Every batch is tested and guaranteed to be free of impurities.

Zero animal products, gluten, GMOs, preservatives, wheat, rye, barley, eggs, or nuts. This product does not contain dairy, soy, corn, yeast, or sugar. 100% vegan. Paleo & Keto-friendly.

2. X USAGE | HOW AND WHEN TO TAKE X

How many capsules do I take at one time?

One serving consists of six capsules, to be taken at the same time.

For those that are exceptionally sensitive, consider starting with one or two on the first day, and increase number of capsules each day until you get to six per day.

What time of day should I take X?

We recommend taking X first thing in the morning.

Although X does not contain caffeine or other stimulants, certain ingredients (such as L-Tyrosine and AlphaSize® Alpha-GPC) may increase energy level and could potentially interfere with sleep if taken late in the day. This varies from person to person.

Should I take X with food?

Take with or without food. There is no effect on rate of absorption.

Can I take X every day?

We recommend “cycling” X—taking it five days a week, followed by two days off, although this is not a hard-and-fast rule.

The reason that cycling may be beneficial is that the days off may magnify the benefits of the ingredients on the days you take X.

(The benefits of cycling are based only on anecdotal reports and not on any rigorous scientific research.)

Can I take more than one serving of X per day?

We recommend taking only one serving of X per day.

Although there is no evidence to suggest that taking two servings in one day would be unsafe, it may increase the possibility of headaches or other minor side effects.

Also, taking more than one serving per day might affect sleep (e.g., increasing lucid dreaming and decreasing “slow-wave sleep”).

Can I take X along with antidepressants or other prescription medication?

If you are taking any prescription medication, consult your doctor before starting to take X or any other supplement.

Can I take X if I am pregnant or nursing?

If you are pregnant or nursing, consult your doctor before starting to take X or any other supplement.

3. HOW X IS DIFFERENT FROM ALL OTHERS

What are the four reasons X is superior to all other brain supplements?

WHY X IS THE BEST

Four reasons X is superior to all others

1. Our formulation is entirely driven by science

Other supplements include ingredients with no benefits to brain function supported by research on human subjects.  We use only ingredients that have brain performance benefits backed by solid clinical research.  And we provide links to that research here.

2. No other product contains these 19 ingredients

As shown in this product comparison chart, there is no other product that comes close to delivering the full range of brain-boosting compounds in X.  The components of X have a synergistic effect which results in a combined impact significantly greater than taking any subset of ingredients.

3. We use research-backed trademarked ingredients 

Trademarked versions of ingredients are considerably more expensive than the generic alternatives.

Not all ingredients have a trademarked version. For ones that do, the manufacturer is staking its reputation on the quality and effectiveness of the ingredient. 

What’s more, clinical research using the trademarked ingredients proves benefits that may not exist for the non-trademarked versions of those ingredients.  

When comparing supplements, always consider which ones use trademarked versions of the ingredients.

4. X is the only product to guarantee results

We guarantee that X will deliver a greater increase in brain performance* than any other supplement you’ve tried, or we’ll buy you that supplement.  

No other brain supplement offers this guarantee. (We have not found any other dietary supplement—in any category—that offers such a guarantee.)

This is a reflection of our level of confidence that you will agree that nothing else compares to the level of brain performance enhancement from X.
