    HSN RAW: 100% pure, authentic, granulated-release caffeine powder

    Slow-release caffeine powder by RawSeries is a food supplement based on CaffXtend® (slow-release natural granulated caffeine).

    CaffXtend® is a prestigious trademark of the company Inventia Healthcare, well known for its granulation system that provides a sustained release of caffeine.

    This is a 100% vegan-friendly product.

    What is Slow-Release Caffeine Powder for?

    CaffXtend® contains 50% pure caffeine.

    Each dose of this dietary supplement contains 400mg of CaffXtend®, meaning it provides 200mg of pure caffeine.

    Caffeine

    • Caffeine helps increase alertness.1
    • Caffeine helps improve concentration.1
    • Caffeine contributes to an increase in endurance performance.2
    • Caffeine contributes to the reduction of perceived exertion during exercise.3

    CaffXtend® is unique: Discover the best slow-release caffeine in HSN's product.

    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.

    Fantastic

    fernando | 22/05/2025

    I take very little, not even half of what is recommended, and it helps me to last all morning without falling asleep, since I train very early and wake up early for the first breakfast, and the truth is that it works very well until noon.

    Me hecho muy poquito, ni la mitad de lo que se recomienda, y me sirve para aguantar tooooda la mañana sin dormirme, ya que entreno muy temprano y me despierto antes para el primer desayuno, y la verdad es que me funciona muy bien hasta el mediodía.

    I take the recommended dose daily and I can't say if I notice the effects, although I also have a high tolerance to caffeine.

    Tomo la dosis recomendada diariamente y no sabría decir si noto los efectos, aunque también tengo bastante tolerancia a la cafeína.
