CaffXtend® raw material

CaffXtend® is unique. It has been developed and manufactured by Inventia Healthcare, a company recognised the world over for its innovative development of this kind of ingredient.

CaffXtend Logo

CaffXtend® uses patented technology that allows the caffeine dose to be released over a 12-hour period (according to the company that owns the trademark: Inventia Healthcare Ltd).

Release pattern

CaffXtend® passes through our body in a different manner to immediate-release caffeine.

Thanks to its granulation technology, the caffeine is released over a long period of time.

Caffeine Sequential Release Curve HSN_Mob1

While typical caffeine supplements release more than 95% of their content in the first few minutes, this one does so over 12 hours.

Slow-release Benefits

One of the main problems with caffeine is that the effects of the compound, when released immediately, peak quickly and then wear off, creating a subjective feeling of fatigue known as 'caffeine crash'.

CaffXtend®, thanks to its unique absorption pattern is more favourable by achieving:

  •  Up to 36% greater improvements in alertness than immediate-release caffeine after 3, 6, and 8 hours.
  •  Fewer adverse effects than with the consumption of high doses of immediate-release caffeine, as the peak reached is lower because it is released in a sustained manner, the jitters that caffeine can generate in consumers are reduced.

All this makes CaffXtend® undoubtedly the best choice for students and workers who work long, mentally demanding days.

Powder format

The format in which this supplement is presented is very convenient, as you only need to mix the powder with water, juice or any drink of your choice to take it.

Vegan-friendly

This supplement is suitable for vegetarian and vegan diets.

Have you tried granulated caffeine before? You should bear in mind that:

It should be noted that because CaffXtend® uses a unique granulation technology, this supplement doesn't dissolve in the same way as other supplements. It is therefore normal to notice small 'grains' while drinking the preparation.

Can I combine this product with others? HSN recommends you with:

What does CaffXtend® Caffeine powder taste like?

Slow-Release Caffeine Powder has a neutral taste, but if the granules are chewed, an intense bitter taste is perceived.

  • Effective caffeine

    Vgh 15/09/2025

    This supplement serves to clear your mind without feeling the energy peak with its respective downturn. It is difficult to dissolve in water. It is a granulate that remains floating and is a bit unpleasant to take. It fulfills its function and gives you energy, of course.
