Common Ingredients in Thermogenic Products

Thermogenic supplements and other weight loss pills use blends of different fat burning ingredients to achieve the desired results.

Let’s take a look at some of the common ingredients used in these products, and how they affect the body.

  • Stimulants – Stimulants are found in most of the best diet pills that work well, and are widely considered to be some of the most important ingredients found in these supplements. Caffeine anhydrous, guarana extract, green tea extract and green coffee extract are the most common stimulants used.
  • Thermogenic extracts & herbs – Many herbal extracts and natural compounds are used in these supplements for their positive effects on thermogenesis. These thermogenic ingredients, are ones such as raspberry ketones, coleus forskohlii, etc. Capsaicin (an acid found in spicy peppers) is also often added for its ability to increase thermogenesis (1).
  • Appetite suppressants – Oftentimes appetite suppressants are added to these products to help you keep your diet in check.
  • Energizing ingredients – Most blends contain caffeine, which we talked about in the stimulants section. Some products also include other energizing ingredients, such as panax ginseng (2), B-vitamins, and more.

What to Look for in a Good Thermogenic Pill

In order to find the right thermogenic for you, you should be aware of the key factors to look for when making a choice.

There are a lot of options out there, some good, some great, and some a complete waste of money!

We encourage you to read fat burner reviews and be informed on the products you choose to use.

Here are some things to look for when making your purchase:

  • Ingredients – obviously, you should first look closely at the ingredients label. What’s in the product? Does it contain proven, clinically studied ingredients to aid fat loss? How much of each ingredient does it contain? The high quality fat burner pills will include a variety of proven ingredients.
  • Brand reputation – who makes the product? Are they a trustworthy company? There are a lot of companies manufacturing these products, but the best fat burners come from, well, the best companies! Our list above contains ONLY products from quality companies – but if you choose to do your own research, be wary.
  • Value for money – how much does it cost? While you shouldn’t necessarily look for the cheapest option, you should always compare costs to see the price per serving/per day. Keep in mind that if you want the fastest fat burner, you’ll be paying a bit more than average.
  • Caffeine content – most of these supplements contain caffeine, but you should be aware of how much caffeine is in each serving. There’s about 80-160mg of caffeine in a cup of black coffee, which is useful for comparing products (3).
  • Convenience of use – the majority thermogenics will require you to take 2+ doses throughout the day. However, some products require 3 or 4+ doses each day, which can become a hassle.
