Welcome to the Dr. Berg's Healthy Keto and Interminate Fasting Podcast, where Dr.

Berg takes you on the journey for the truth about getting healthy and losing healthy weight.

Let's talk about the seven warning signs of a B-12 deficiency.

B-12 is kind of an important vitamin. It's involved in making DNA,

myelin sheath, which is the coating around the nerves. Like in this wire, if we were to take off

the outside coating, okay, that would potentially short-circuit. Same thing that happens in

the nervous system. We'll cover that. Also B-12 is involved in making things like red blood cells,

which is kind of important. So B-12 is very, very vital. And it's important for you to know

these symptoms because there's usually like seven big symptoms that are not necessarily related,

but it's important to identify them because one thing about a B-12 deficiency is that if you're

deficient, you can actually experience irreversible damage to your nervous system. So we're going to

cover all that. But I first wanted to mention one thing about the type of B-12. There's two types.

There's a natural version of B-12. And there's a synthetic version. Of course, I'm going to

recommend always take the natural version. And the natural version is called methyl-cobolamine.

That's the one that you want to take in your supplements. The other one that's synthetic that I

don't recommend is called cyanocobolamine. I recommend you avoid that one because it's synthetic.

Now, what's kind of interesting about B-12 is that the main reason why people are deficient

is not necessarily that they're not eating foods with B-12. It has to do with male absorption,

or they're not able to absorb B-12. The B-12 absorption is very complex. There's a lot of things

that are happening from the stomach to the small intestine in the absorption. Your body needs

this carrier transportation protein to help you absorb it. It's called intrinsic factor.

And if you don't have it or you have an autoimmune disease, you can get something called
