Slow-release caffeine (400mg CaffXtend™)

Caffeine SR. An old friend RAW. Now in capsules!

Prolonged-release caffeine (400mg CaffXtend™) is a dietary supplement from RawSeries in plant capsule format with no additives, no fillers and only pure, certified by HSN.

The granulation system developed by Inventia Healthcare for the development of the prestigious raw material CaffXtend™ allows a system that is more easily adaptable to the cognitive needs of students and workers who may also want to enjoy a product of the highest quality in pure form, without needing to use the powder format which can be less practical and more suitable for athletes preparing pre-workout drinks.

Prolonged-release caffeine is a product of our new '100% Pure' encapsulated line from RawSeries.

CaffXtend™ is unique. Now in additive-free capsules

CaffXtend™ is a raw material we love to work with. You’ll find it in many of our superstar products, not only as a single ingredient, but as a central feature in many formulas like our Best-seller: Caffeine Intelligence.

The reason we like it so much is its release profile is unique: While normal caffeine, without special coating agents, is released in about 5–10 minutes, as happens with our natural caffeine in vegetable capsules (the so-called 'instant release').

New packaging! Your RAW product as always, now in vegetable capsules

At HSN we refresh ourselves! And we’ve spotted a clear need:

People who want to use pure RAW products, but don’t like or find it inconvenient to dose in milligrams in powder form, so they need a precision scale; and they’re not used to, or want to encapsulate at home because it’s tricky or tedious.

At HSN we’ve offered, from the start, a huge variety of encapsulated products and tablets, and CaffXtend™ isn’t an exception, which you can find in our gama Essentials, being one of our recently launched, best-selling mono-ingredient items.

Purity guaranteed. In close collaboration with Inventia (creator of CaffXtend™)

Inventia Healthcare Ltd is a renowned Indian company from the Mumbai region, specialized in researching herbal extracts and nutraceuticals like caffeine, a compound they've invested a lot of research into until they reached the point of developing caffeine with a unique release pattern.

You should note that any average caffeine has a fast release; it’s absorbed in the same stomach, without needing to pass to the intestine, so within minutes it’s already in the blood, absorbed completely and already producing effects all at once.

This patented raw material guarantees prolonged release, without the need to use animal coatings or lacquers like other brands that instead of granulating with slow-release systems use fast caffeine with entéric coatings, which isn’t effective or efficient.

CaffXtend™ is the best slow-release system developed to date.

High caffeine dose = 200mg pure. Transparent labeling, granule breakdown

At HSN we follow good manufacturing and labeling practices.

Our own factory has all the guarantees and quality certifications for food safety, top-tier, and compliant with the EU’s strictest standards.

Unfortunately not all companies are the same.

A common practice is to indicate on products that supply CaffXtend™: Caffeine (CaffXtend™) 200mg.

That’s a sham!

CaffXtend™ has a unique granulation system that reduces space for pure caffeine, so CaffXtend™ as such only provides 50% caffeine per mass unit, i.e., to provide 100mg of caffeine you need 200mg of CaffXtend™.

When companies state the above, you may get misinformation that the product provides 200mg of caffeine, when in fact it only provides 100mg.

What properties does this caffeine have?

Caffeine has positive properties on physical performance and cognitive performance. Four effects stand out:

•  Helps to increase alertness.¹
•  Helps to improve focus.¹
•  Contributes to an increase in endurance performance.²
•  Contributes to the reduction of perceived exertion during exercise.³

A unique release profile: Up to 12 hours

Many people don’t like this, which is why they don’t use caffeine: it makes them jittery and its effects drop off abruptly, causing the famous 'caffeine crash.'

Prolonged-release caffeine stands out by not releasing so quickly, but by having a unique release profile.

This allows:

1.  That jitters in sensitive people are much lower since it doesn’t flood the system and avoids spikes.
2.  Since there are no spikes, there are no crashes, making caffeine effects more sustained and much better.

Is this caffeine for me? Ideal profiles

The CaffXtend™ is perfect for students and people seeking concentration in long sessions, during sustained days; and yet they don’t seek a high peak of effects.
