Smart Caffeine by EssentialSeries is a food supplement in vegetable capsules, based on a combination of natural caffeine anhydrous from coffee beans, the amino acid L-Theanine, pantothenic acid, vitamin B6, and zinc.
Caffeine is the most widely used alkaloid in the world through the extensive use of drinks such as tea and coffee. L-theanine is the main amino acid constituent of the leaves of the tea plant (Camellia sinensis).
This product is made from ingredients that are 100% free from traces of animal derivatives.
Smart Caffeine is a product suitable for vegetarians and vegans.
The caffeine in this formula is CaffXtend®. A unique ingredient, as it is released over 12 hours thanks to a patented technology (according to Inventia Healthcare Ltd, the brand's proprietary company).
Immediate-release caffeine is not the best option when it comes to using caffeine for studying, as its effect is fast and intense, but it does not last over time and after a few hours fatigue sets in quickly and unexpectedly, making you feel a 'dip'. This is what we called a 'caffeine crash'.
As CaffXtend® is released for much longer than immediate-release caffeine:
Up to 12 hours vs minutes.
Its effects are more sustained over time, something that has been highlighted by recent studies showing that, although total caffeine absorption is identical between the immediate and prolonged speed, its effects are better in the case of the prolonged speed several hours after ingestion, and there is no caffeine 'crash' because there are no 'peaks' or ' dips'.
CaffXtend® is the best option for students, and that's why it's the star of our smart caffeine.
The dose ratio between caffeine and L-theanine is an important factor in establishing the pattern of action of the compound, and the choice of dose is relevant.
Our product contains a dose of 150mg of caffeine and 200mg of L-theanine per capsule.
Capsule products sometimes present problems for people who do not consume animal foods, as gelatine is used as a glazing agent.
HSN avoids the use of gelatine in our capsules and instead uses a polymer derived from cellulose, of vegetable origin.
Our capsules are veggies, and smart caffeine is a 100% vegetarian and vegan friendly product.

A satisfied customer says:
I love it
Laura | 19/02/2024
I am delighted with this long-acting caffeine, as the normal one made me too active. You can feel it throughout the day, and it's ideal for the afternoon and evening shifts.
A critical customer says:
It hasn't kept me awake at night.
Cristina | 22/02/2024
I bought it as a substitute for coffee in the morning and even taking an extra coffee has not kept me awake at midday. I have to say that I have been taking it for 3 months.

Caffeine supplement
HSN Smart Caffeine has worked well for me before training or for long days at work. It gives me constant energy without making me nervous or causing a slump afterwards. You can feel the effect quickly and it helps me concentrate better. Also, the capsules are convenient to take and don't taste bad. It's a good choice if you want a clean energy boost.

Effective!
For those who need a boost of energy, alertness and focus, this is a great supplement. Because it's a prolonged release, there are no energy spikes - which is great.
