Intracellular testing, or the CMA Cellular Micronutrient Assay, measures over 100 vitamins, minerals, amino acids, and antioxidants inside your cells—not just in your blood. Unlike serum tests, which show short-term levels, intracellular testing reveals what your cells have been missing over the last 100 days. Low levels can mean weak enzymes, non-functioning proteins, and accelerated aging. By identifying deficiencies and matching them with the correct nutrient forms for your genetics, you can target fatigue, anxiety, depression, and other chronic issues at the root. Get your CMA by calling our office at 801-796-7667.

How do you know if you need intracellular testing? Well, let's talk about what intracellular testing is. The CMA, cellular micronutrient assay, is a very cool test that looks at micronutrient levels inside of your cells. That means uh vitamins, minerals,

0:17

amino acids, as well as antioxidants. We look at all of these levels, over 100 substances through our intracellular testing. What's the benefit of looking at intracellular levels? Well, your blood serum levels do show very important metrics. Uh, and so we do like

0:33

to look at both both sides, intracellular levels as well as blood serum levels of many key vitamins and minerals. Uh, but an intracellular level lets you know what your cells are lacking in from over the last 100 days or so. If you have an intracellular

0:50

deficiency, that means that cell is severely lacking of specific nutrients. Let's say if you have an intracellular glutathione deficiency, well, glutathione is the master antioxidant in your body. And if you're low in inside your cells, you're going to be low

1:06

throughout your entire body. This is hugely problematic and may contribute be one of the major contributing factors to aging as well as many other oxidative stress and oxidative damage related diseases. If you're low in any of the

1:21

major amino acids, the essential amino acids, if you're low inside of your cells, you're going to have massive problems as well. If you're low in an amino acid, this is the building block of all the proteins and enzymes within your body. If you don't have sufficient levels of it, you're going to be making

1:38

much less efficient enzymes, if not non nonfunctioning proteins. This will be majorly devastating to you as well. So what is the benefit of looking at these intracellular levels? If you can find these intracellular deficiencies, you

1:55

can treat them and based on your genetics, you can treat with the proper forms of vitamins, minerals, and amino acids that your body needs. And this is something that a lot of people overlook is using and utilizing the correct forms of these vitamins. So let's look at

2:10

cobbalamin real quick. There are four versions of cobalamin. methylcobalamin, adenosylcobalamin, hydroxycobalamin, and cyanocobalamin. Most supplements will have cyanocobalamin which has literally a cyanide molecule connected to a cobalt molecule. That's what makes up a a B12

2:28

cyanocobalamin. And there's much better options. You don't need that as much. Uh, and that's just the cheapest version that everyone uses. Let's also look at B9 folate. There's several forms of folate such as folinic acid, folic acid, folate, the MTHF, methyl tetrahydropholate. Uh

2:44

there's several different ones, but what version do you need? What version do your cells crave? Uh this is and based on your genetics, this is something that we can really dive into and what can be so beneficial to you personally. So looking at your intracellular levels is

3:01

really just the first step. Let's find out what you're deficient in. Let's get you feeling better. If you have major fatigue, if you have unending chronic fatigue as well as anxiety and depression caused by this fatigue, hey, there's something going on and we can look inside your cells and we can fix

3:17

it. How about that? Yeah, take a look. Fix.
