Do Kalms contain caffeine?

Kalms does not contain caffeine, and there is a simple and scientific reason behind it. Caffeine is the world’s most used natural stimulant, which you can find in different types of beverages such as energy drinks, coffee, sodas, green tea, black tea, and even dark chocolate.

Meaning, it is not a good option for relieving anxiety, stress or even as a sleeping aid, on the contrary, your anxiety and stress levels will spike and won’t be able to sleep at all. 

Moreover, we know that caffeine stimulates the brain and our central nervous system helping us to stay alert and awake.

Once we have caffeine intake our body quickly absorbs it and sends it to our bloodstream.

After it reaches our bloodstream, it goes to our liver and it is broken into compounds that may affect the function of many organs.

As indicated by Alina Petre from, “caffeine’s main effect is on the brain and It functions by blocking the effects of adenosine, which is a neurotransmitter that relaxes the brain and makes you feel tired.”  

Normally, adenosine levels tend to build up throughout our day making us feel more tired and making us want to go to sleep.

Subsequently, caffeine acts by connecting the receptors in the brain without activating them, reducing our tiredness.  

As we have discussed, caffeine can’t be one of the ingredients in Kalms because they actually need to have the contrary effect (sedating) to help relieve mild anxiety symptoms, stress, and even serve as a natural sleeping aid.

 What if I can’t sleep?

You may be familiar with the feeling of being fatigued or drowsy during the day, or maybe even both.

If so, you may have turned to your morning caffeine fix to be able to cope with the day ahead. The lack of sleep can be responsible for being irritable, memory problems, or difficulties recalling information.

You may have been diagnosed with insomnia or you may suspect you have it. Let’s see some of the symptoms:

•    Difficulty falling asleep

•    Waking up often during the night and having trouble getting back to sleep

•    Waking up too early in the morning

•    Feeling tired upon waking

In addition, you may be looking for all the options available to you to treat insomnia.

However, you may have also been considering antihistamines found in over the counter medication such as Nytol.
