Caffeine Pills – The Basics
As we’ve already mentioned, Caffeine is a popular stimulant found in a variety of popular beverages such as tea and coffee, as well as some commercially-available energy drinks.
You’re probably already very familiar with Caffeine and its effects, especially if you’re a regular coffee drinker.
Although Caffeine is usually consumed due to its presence in drinks such as coffee, it is also available as a standalone ingredient for food supplements.

One of the most popular forms of Caffeine included in food supplements is Caffeine Anhydrous, but it is also sometimes included in different forms such as coffee bean extracts.
The term ‘Caffeine Pills’ simply refers to food supplements that contain Caffeine as their main ingredient.
These products are available in a capsule or tablet form, and they usually contain a sensible dose of Caffeine to help support your goals.
Caffeine supplements are used in a variety of situations. For example, some people may choose to take a small dose of Caffeine before a workout, while others may simply turn to a supplement to help support them when they need an added boost.
Of course, not all supplements are created equal, and it’s always a good idea to do some of your own research into any product you’re thinking of buying before using it for the first time.
So, now that we’ve covered some of the basic things to bear in mind when it comes to Caffeine supplements, it’s time to focus on some of the things to look for in a product.

Things To Look For In A Caffeine Supplement
Firstly, it’s always best to consult your doctor before taking any new food supplements, especially if they contain Caffeine.
It’s also important to remember that food supplements are not intended to replace a varied, balanced diet and a healthy overall lifestyle.
Caffeine is a powerful stimulant, so it’s important to make sure that you’re not consuming too much and that you keep your total intake from all sources in check.
Some people have different tolerances to Caffeine, so its effects can vary from person to person.
However, the FDA in the US currently recommends that adults do not consume more than 400mg of Caffeine per day from all sources (including both drinks and supplements).
To put this amount into context, you’d expect to find around 100mg of Caffeine in a regular cup of coffee.
Caffeine is not recommended for consumption by children and pregnant or breastfeeding women. As we mentioned above, you should always speak to your doctor before taking a Caffeine supplement, as they are not suitable for everyone.
It’s important that you carefully read the label of any supplement you’re thinking of taking, especially as many of them say that the products are not suitable for children and pregnant or breastfeeding women.
When it comes to choosing a Caffeine supplement, there are a few things to look out for.
Firstly, it’s generally better to go for a supplement that has a clean label and doesn’t contain unnecessary additives or ‘filler’ ingredients.

We also recommend choosing a product from a brand who transparently list the doses of the active ingredients on the label, so you’ll know exactly what’s contained in each tablet or capsule.
Of course, one of the main things to check is the actual Caffeine content in each capsule. You’ll want to be sure that you’re not overdoing it when it comes to your overall Caffeine consumption.
Some Caffeine pills contain added ingredients such as plant extract, vitamins and minerals. Be sure to carefully check the label to ensure that you know exactly what’s contained in each tablet or capsule. If you follow a vegan diet, check that the supplement you’re considering doesn’t contain any animal products.
