Should you take L-Glutamine if you have Mast Cell Activation Syndrome or Histamine Intolerance?
L-Glutamine can sometimes be helpful for people with Mast Cell Activation Syndrome or Histamine Intolerance. But sometimes it can make people worse.
It really did for me. When I was seeking answers, numerous people had me try L-glutamine for leaky gut.
But it always made me really anxious. And have even worse insomnia.
I just felt horrible on it. And some of my practitioners didn’t believe me – they thought I was making this up. They thought – how could a common amino acid make someone worse?
But I wasn’t making it up.
And I’ve seen a number of other people struggle with it.
Why is this?
If you are someone who has struggled with L-glutamine, I want to dive into this
But first, let’s look more at the roles of L-glutamine.
Roles of L-glutamine to know about for those with Mast Cell Activation Syndrome or Histamine Intolerance
L-glutamine is one of the most common amino acids in the body.
It has many roles in the body:
- as a neurotransmitter
- in neuroplasticity
- supporting immunity
- gut lining repair
- other tissue repair
- in the production of glutathione
L-glutamine is very abundant in the brain. It causes neurons to fire. And higher levels of it make people intelligent.
L-glutamine may even help reduce mast cell inflammatory cytokines, according to research. Wow!!
So, this all sounds pretty good – right?
Except some people with Mast Cell Activation have excess glutamate.
And this can sometimes mean L-glutamine as a supplement can cause problems.
Let’s look at this next.
Problems causing Excess Glutamate for those with Mast Cell Activation Syndrome or Histamine Intolerance
There are many things that can lead to high glutamate, such as genetic variants that can contribute to high glutamate levels.
Also, when people have had brain injuries, it is common to have high glutamate levels.
This is what happened for me. I was kicked in the head by a horse when I was 9 years old.
I developed anxiety and sleep issues then. Of course, I didn’t know anything about glutamate at that time.
These problems continued well into my adult years. I had brain inflammation. And a leaky blood brain barrier.
On top of that, I had leaky gut. And a number of genetic variants associated with high glutamate. This actually led to a perfect storm for high glutamate. And L-glutamine sensitivity.
Have you had any of these challenges with your health?
Let’s look at more of the symptoms associated with high glutamate next.
Symptoms of high glutamate to know for those with Mast Cell Activation Syndrome or Histamine Intolerance
High glutamate levels have been associated with:
- panic attacks
- too much adrenal activity
- learning disorders
- Neurological problems
- Many other symptoms
Do you have any of these?
Too little glutamate means the neurons in the brain don’t fire fast enough. But too much glutamate means those neurons fire too fast.
And they can start to burn out. Like a lightbulb burning out.
L-glutamine doesn’t cause problems for everyone. But for many with Mast Cell Activation, at least, it may cause issues.
There is no One Size Fits All in Supplements for those with Mast Cell Activation Syndrome or Histamine Intolerance
This is why it’s so important to pay attention to your body when you take supplements.
There is no One Size Fits All approach that works for those with Mast Cell Activation Syndrome or Histamine Intolerance.
This is because there are so many different possible root causes. And so many different types of genetic variants.
Between all the people with Mast Cell Activation I’ve worked with and talked with… I’ve seen that no 2 people with this are alike.
This is why it’s so important to work with a practitioner who really gets this. Or learn as much as you can about how supplements work.
This way you can know more about whether something will work for you or not.
It literally took me decades to figure all this out. And I’m on a mission to help others learn this.
Not everyone can get an appointment with me. And there are too few practitioners right now that really understand how to work with Mast Cell Activation.
This is why I designed this course that I’m very excited about. It’s called the “Top 8 Mast Cell Supporting Supplements Masterclass.”
If you are struggling with how to know which supplements are right for you, you’ll want to check it out.
