Caffeine and Health Update
Caffeine intoxication is a very rare condition. Experts say that around 250 mg of caffeine per day is a recommended safe amount to consume. Caffeine overdose may happen if you drink more than 500mg to 600mg caffeine daily. We have seen in the news recently how certain energy drinks loaded with Caffeine have produced very negative effects and even fatalities. Here we try to explain a little more about what is happening when we drink caffeine in a drink.
How does the “Safe Amount” relate to what I am drinking?
A typical cup of Green tea, of around 250 ml, has approximately 30 mg of caffeine. We use decaffeinated tea for our CALM&RELAX healthy functional drink. Decaffeination removes most (well over 95%) of the caffeine. In our other blends we use about 40% green tea so in a typical cup of 250 ml of UP&GO, SLIM&FIT and YOUNG&FUN there is about 12 mg. As you can see from the table below this is a very small amount and to arrive at the 250 mg that the experts are calling the limit you would have to drink an awful lot of our infusion!
Theanine in green tea also negates the jittery effects of green tea so you can remain “wakeful” but not get too restless which can happen after a strong coffee. In our UP&GO energy shot drink (Male ♂ and Female ♀ orientated versions) there is zero caffeine….we don’t use Green Tea in those recipes!
How does it work?
About Caffeine Chemistry: Caffeine is believed to work by blocking adenosine receptors in the brain and other organs. This reduces the ability of adenosine to bind to the receptors, which would slow down cellular activity. The stimulated nerve cells release the hormone epinephrine (adrenaline), which increases heart rate, blood pressure, and blood flow to muscles, decreases blood flow to the skin and organs, and causes the liver to release glucose. Caffeine also increases levels of the neurotransmitter dopamine.
The effects of caffeine on health have been investigated and significant amounts of caffeine may decrease bone mass density, most likely by interfering with the body’s ability to absorb calcium, which may lead to osteoporosis.
- Caffeine may cause or worsen painful, lumpy breasts (fibrocystic disease).
- Caffeine may have a negative effect on a child’s nutrition if caffeinated drinks replace healthy drinks, such as milk. A child who consumes caffeine may also eat less, because caffeine reduces the appetite.
There are also some side-effects with excessive consumption and Caffeine can lead to, amongst others:
- A fast heart rate
- Difficulty sleeping
Excessive caffeine consumption may also cause your muscles to contract irregularly, leading to symptoms of shakiness or muscle tremors. Your heart rate may also increase, which may cause shortness of breath, dizziness or chest discomfort. Extremely high doses of caffeine may cause life-threatening heart rate changes requiring immediate medical attention. Contact your doctor immediately if you experience sudden or severe chest discomfort. This symptom of a caffeine overdose may also be signs of a heart attack. Also, in pregnancy it’s best to cut out caffeine as much as possible.
