    Discover a unique HSN development with the best slow-release caffeine raw material: CaffXtend®.

    CaffXtend® raw material

    The 200mg of pure caffeine contained in our SR caffeine comes from CaffXtend®, a unique ingredient.

    CaffXtend Logo

    CaffXtend® employs a patented release modification technology platform, which causes a single dose of caffeine to be released over a 12-hour period, according to the company that owns the trademark: Inventia Healthcare Ltd.

    Release pattern

    CaffXtend® has different pharmacokinetics from other immediate-release caffeine.

    Its different dissolution profile is due to its granulation technology, which converts its caffeine into a slow-release compound.

    According to data provided by Inventia, based on its own research, CaffXtend® caffeine is released for more than 12 hours.

    Caffeine Sequential Release Curve HSN_Mob1

    While other products made from regular presentations of immediate-release caffeine release more than 95% of their content in the first 5 minutes (Sager et al., 2019).

    In convenient capsule size.

    The product is easy to use and comes in convenient capsule format.

    When to choose slow-release caffeine versus fast-absorbing caffeine?

    Immediately absorbed caffeine is excellent for use before short workouts, lasting 1-2 hours, as it peaks and then the concentration drops rapidly.

    However, when you are studying, for example, this 'dip' is very noticeable, it is known as a 'caffeine crash', which makes you feel much more tired after a few hours.

    Slow-release caffeine by CaffXtend® is the best choice for students and workers as, thanks to its much longer release, recent studies have shown that the effects achieved are greater from consumption up to 8 hours later (ideal for long study sessions and working days), causing fewer jitters than immediate caffeine, as it does not reach such high peaks in the blood.

    many times it feels bad when taking it, it may be because of the type of caffeine or it may depend on the person.

    SLOW-RELEASE CAFFEINE (400mg CaffXtend®)

    Good energy supplement!

    A good, safe caffeine supplement (CAFFXTEND patent), in a concentration that allows you to draw out effects, which makes it great for boosting energy and focus, and a prolonged effect, throughout the day (12 noon), without peaks. I usually take it in the morning on days when my energy or mood is low and I feel that boost throughout the day! And at a good price.

    Um bom suplemento de cafeína, seguro (patente CAFFXTEND), numa concentração que permite retirar efeitos o que o torna ótimo para um boost de energia e foco, e um efeito de forma prolongada, ao longo do dia (as 12h), sem haver picos. Costumo tomar de manhã em dias de menor energia ou disposição e sinto esse boost ao longo de dia! Além de ser a um bom preço.

    Lasts 12 hours.

    You should definitely make sure you only take it in the morning. But there are many uses such as a longer trip, shift work where it has helped me!

    Man sollte unbedingt darauf achten, es nur vormittags zu nehmen. Aber es gibt viele Einsatzzwecke wie eine längere Reise, Schichtarbeit wo es mir geholfen hat!

    SLOW-RELEASE CAFFEINE (400mg CaffXtend®)

    Highly effective

    It is very effective. Except for one day when it hasn't had much effect, perhaps because I slept less, it usually lasts about 12 hours. It is true that it doesn't give you the high that a coffee gives you and at the beginning I am tired but then I last all day and I don't feel sleepy at all. Of course you have to be careful if you take it a little late because as I say, the effect lasts me about 12 hours. It is very worthwhile.

    Es muy eficaz. Excepto algún día que no me ha hecho demasiado efecto quizá por dormir menos, me suele durar su efecto unas 12 horas. Es cierto que no da el subidón que te da un café y al principio estoy cansada pero luego aguanto todo el día y no noto apenas sueño. Eso sí hay que tener cuidado si te la tomas un poco tarde porque como digo a mí me dura el efecto unas 12 horas. Vale mucho la pena.
