1. What are theine and caffeine?

  • Theine is the stimulating substance coming from tea. It is the result of oxidized polyphenols, a type of micronutrient, that provides energy, boosts digestion, and brings relaxation to the body. Tea types that contain theine are black, green, white, and oolong.
  • Caffeine is the stimulating substance you find in coffee and cacao products. It is an alkaloid, a type of nutrient, that acts on energy, metabolic, cardiac, and respiratory systems. 

In reality, theine and caffeine are the same molecule, there is no difference under the chemistry point of view. However, theine and caffeine have different energy impacts on the human body, and this is what we will focus on today.

2. The impacts of theine and caffeine for your energy 

When we drink stimulants, they go to the stomach and small intestine then enter to our bloodstream.

The impacts of theine:

  • Theine provides long-lasting energy – about 6 to 8 hours because theine is more complex and the body needs longer time to break it down and completely absorb it.
  • Theine also gives improves concentration and learning ability while giving a sense of relaxation.
  • Theine is linked with health benefits including weight loss, prevention of cardiovascular disease, and enhancing the immune system for long-term use.

A 250 ml cup of tea generally contains about 30 to 50mg of theine (1).

The impacts of caffeine: 

  • Caffeine gives a burst of energy for 2 to 3 hours followed by a crash. This is because caffeine is well absorbed by the body, and the short-term effects are usually experienced between 5 and 30 minutes after having it.
  • Caffeine causes many people to experience jitters, a feeling of anxiety coming from our overstimulated nervous system.
  • Caffeine can lead to addiction if used daily, which means, without it, you might experience withdrawal symptoms like headache and fatigue.

A 250 ml cup of coffee may contain between 80mg to 230mg of caffeine. Popular types of energy drink can contain up to 250mg of caffeine and it’s too much for the human body. (2)

Natural and synthetic sources of caffeine:

  • Natural caffeine is found in tea, coffee, chocolate, and natural drinks. They come from seeds, nuts, or leaves of a number of plants native to South America and East Asia, in detail from tea leaves, coffee beans, cocoa beans… (3). It provides energy, but it also has its own exclusive antioxidant benefits which can help prevent heart disease and Alzheimer’s. 
  • Synthetic caffeine is found in chemical soft drinks, energy drinks, and supplements. Synthesised caffeine is absorbed through the digestive system much faster than naturally occurring caffeine, providing a quicker spike and therefore a quicker crash.

Therefore, synthetic chemical sources are often harmful to health if used regularly and long term, you should choose natural sources to improve your health.

Drinkizz nutrition experts recommend that you use tea so that you can provide a better source of energy, and this is why we chose it as the base for Drinkizz.
