HSN Introduces Smart Caffeine. Your best ally in your study sessions

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.

A unique formulation: Intelligent caffeine contains CaffXtend® for the best effects

CaffXtend^®

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).

Why do we use CaffXtend® in our improved smart caffeine?

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.

Caffeine Sequential Release Curve HSN_Destkop

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.

Smart Caffeine properties of interest to you as a student

Caffeine

Caffeine helps improve concentration.²

Pantothenic acid

Pantothenic acid contributes to normal intellectual performance.
Pantothenic acid contributes to the synthesis and normal metabolism of steroid hormones, vitamin D, and some neurotransmitters.

Zinc

Zinc contributes to normal cognitive function.

At HSN we take care of the details: Our smart caffeine is the result of our love of food supplements

Carefully selected doses.

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.

In vegan capsules

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.
