But what is caffeine? And how does it work within your body?

What is caffeine anhydrous?

Caffeine is a natural stimulant, which means it works by stimulating your brain and nervous system. This leads to a heightened state of alertness and can make you feel more awake and keep tiredness at bay.

This stimulant is found in the seeds, nuts and leaves of certain tropical plants.

In your day-to-day life you’ll find caffeine most commonly in coffee, teas and, more recently, in energy drinks.

‘Going for a coffee’ or grabbing a cup of tea is a huge part of modern culture, however the story began thousands of years ago. Historians have found evidence of people drinking tea as far back as 2700 BC [1].

It’s now a huge part of our lives and it’s estimated that around 90% of adults in North America consume caffeine every single day [1].

Caffeine anhydrous is often used in supplements or energy products. The word ‘anhydrous’ translates to ‘without water’.

To create this variant, caffeine is separated and extracted from the leaf, seed or nut and dehydrated. Once this process is complete, you’re left with a powder form, which is more concentrated than anything you’d find in a coffee or tea.

Key Point: Caffeine anhydrous has been shown to have a greater ergogenic effect and can enhance physical performance better than other variants of the stimulant [2].

Sources of caffeine anhydrous

The ideal growing area for caffeine-bearing plants is usually in high-altitude subtropical destinations, or in equatorial areas. Within these plants, the stimulant is in the leaves, nuts or seeds, depending on the variation.

Coffee predominantly comes from the Coffea arabica plant. This evergreen shrub accounts for almost 75% of the world’s coffee production [3].

The other 25% is almost completely made up of Coffea robusta [3].

For tea, caffeine is found within the leaves of the Camellia sinensis plant. The way in which the leaves are prepared after they’re harvested determines the type of tea you have.

How much caffeine should I take?

Fatal doses of caffeine are reported at 500mg in a single serving, so it’s wise to consume no more than 200mg at a time [17].

In exercise, many think it’s a case of the more the better. However, athletic performance in endurance tasks has been shown to heighten after as little as 2.3mg/lb of body weight [18].

Again, in HIIT and resistance training, physical performance has been greatly improved by small-moderate dosages [7] [19].

This indicates anything from 150-200mg of the stimulant is enough to improve exercise performance for most people.

The American College of Obstetricians and Gynecologists have stated that pregnant women should aim to cap their caffeine intake at 200mg a day [20].

Pregnant women should avoid taking the stimulant or lower their intake, as it can cause miscarriage or a lower birth weight in babies [23].

It’s also worth noting that the genealogical make up of some people mean they’re more sensitive to the effects of the stimulant [24]. Caffeine is also highly addictive [1], which can influence the amount you drink.
