The Mineral Files Part 4: Everything Your Doctor Didn't Tell You About Potassium | Episode 35 · The Brain Dump

• 0:00
  SPEAKER_00: Before we dig in today, I need for you to hear this.
• 0:02
  SPEAKER_00: I am a licensed professional counselor, a coach, and a neuroscience nerd.
• 0:06
  SPEAKER_00: I am not your doctor, your nutritionist, or your prescriber.
• 0:10
  SPEAKER_00: Nothing I share here is medical advice.
• 0:13
  SPEAKER_00: This episode is for educational purposes only and reflects my personal journey with the hair tissue mineral analysis.
• 0:19
  SPEAKER_00: If you're curious about your own mineral status, please work with a qualified practitioner who can interpret your specific results in the context of your full health picture.
• 0:28
  SPEAKER_00: Got it?
• 0:29
  SPEAKER_00: Great.
• 0:29
  SPEAKER_00: Let's get into it.
• 0:30
  SPEAKER_00: Welcome to the Braind Dump with Sandy Boone.
• 0:33
  SPEAKER_00: I'm Sandy, licensed professional counselor, coach, neuroscience enthusiast, and apparently someone who collects interesting lab results.
• 0:40
  SPEAKER_00: This is the Mineral Files, the series where I take my actual hair tissue mineral analysis results and break them down in plain language so you can understand what minerals actually do in the body, not the simplified version, the real version.
• 0:55
  SPEAKER_00: Today's mineral is potassium.
• 0:57
  SPEAKER_00: And I need to be honest with you, when I first saw my potassium number on this report, I didn't fully grasp what I was looking at.
• 1:04
  SPEAKER_00: Now I do, so buckle up.
• 1:11
  SPEAKER_00: Perhaps your thyroid has been on the struggle bus for as long as you can remember.
• 1:16
  SPEAKER_00: Maybe your TSH looks fine on your blood work, but you feel exhausted, slow, cold, and foggy anyway.
• 1:24
  SPEAKER_00: Maybe you've been told everything is normal while you sit here thinking this doesn't feel normal.
• 1:30
  SPEAKER_00: Here's what almost no one tells you.
• 1:32
  SPEAKER_00: Your thyroid may not be the actual problem.
• 1:35
  SPEAKER_00: It might be the potassium.
• 1:37
  SPEAKER_00: My HTMA, the hair tissue mineral analysis that we've been talking about for a few episodes now, showed a potassium sitting at four.
• 1:46
  SPEAKER_00: The optimal value is around 10.
• 1:48
  SPEAKER_00: My calcium to potassium ratio, it was 40.25.
• 1:53
  SPEAKER_00: The optimal range is 4.2 to 8.
• 1:57
  SPEAKER_00: My number is nearly five times the upper end of optimal.
• 2:01
  SPEAKER_00: And the lab didn't just flag this.
• 2:04
  SPEAKER_00: They named the section high calcium potassium ratio and hyperthyroidism.
• 2:10
  SPEAKER_00: Not a hint, not a maybe.
• 2:12
  SPEAKER_00: The lab said it directly.
• 2:14
  SPEAKER_00: And that's what this episode is about.
• 2:17
  SPEAKER_00: Potassium, what it actually does, why your thyroid can't function properly without it, and what it means to have it depleted at the tissue level.
• 2:25
  SPEAKER_00: What mine looked like when I finally had the data to see it.
• 2:29
  SPEAKER_00: So my numbers at a glance.
• 2:31
  SPEAKER_00: My HTMA potassium showed four.
• 2:34
  SPEAKER_00: Optimal is about 10.
• 2:36
  SPEAKER_00: My calcium potassium ratio was 4.25.
• 2:40
  SPEAKER_00: The optimal is 4.2 to 8.
• 2:43
  SPEAKER_00: So I was nearly five times the upper limit.
• 2:46
  SPEAKER_00: My sodium potassium ratio was two.
• 2:50
  SPEAKER_00: Optimal is 2.2 to 6.
• 2:53
  SPEAKER_00: And here's the kicker.
• 2:55
  SPEAKER_00: My serum potassium done by my PCP, 4.5.
• 3:00
  SPEAKER_00: Completely normal, but the blood panel can't see the tissue story.
• 3:04
  SPEAKER_00: What is potassium?
• 3:06
  SPEAKER_00: Potassium is the primary electrolyte inside your cells.
• 3:10
  SPEAKER_00: When most people think of electrolytes, they think of sodium, which we covered in the last episode.
• 3:15
  SPEAKER_00: And sodium is the extracellular electrolyte, the one that lives primarily outside of your cells.
• 3:22
  SPEAKER_00: Potassium is the intracellular counterpart.
• 3:25
  SPEAKER_00: It's what's supposed to dominate inside the cell.
• 3:28
  SPEAKER_00: Every cell in your body uses potassium.
• 3:31
  SPEAKER_00: Muscles need it to contract and relax.
• 3:36
  SPEAKER_00: Nerve cells need it to fire properly.
• 3:39
  SPEAKER_00: And your endocrine glands, including your thyroid, they need it to do their jobs.
• 3:44
  SPEAKER_00: The human body contains roughly 150 grams of potassium, and about 98% of it lives inside cells.
• 3:51
  SPEAKER_00: The serum level, what shows up on a blood panel, reflects only that outer 2%.
• 3:58
  SPEAKER_00: That tiny pool is kept remarkably stable by the kidneys because if serum potassium drops significantly, you'd be in cardiac trouble.
• 4:06
  SPEAKER_00: But that stability in the blood, it tells you almost nothing about what's happening at the tissue level.
• 4:12
  SPEAKER_00: And that's why the HTMA exists.
• 4:15
  SPEAKER_00: It measures what's in the tissue, what's actually inside the cells, rather than what the body is working hard to keep constant in the blood.
• 4:24
  SPEAKER_00: My serum potassium is 4.5, solidly normal by any lab's reference range.
• 4:30
  SPEAKER_00: My HTMA potassium is 4.
• 4:33
  SPEAKER_00: The optimal is approximately 10.
• 4:36
  SPEAKER_00: It's the same mineral, but two completely different pictures.
• 4:40
  SPEAKER_00: And this is why I get worked up about the serum versus tissue distinction.
• 4:44
  SPEAKER_00: My blood work looks fine.
• 4:46
  SPEAKER_00: My cells are not fine.
• 4:48
  SPEAKER_00: And the only way I would have known that is with a tool that looks at the cells.
• 4:53
  SPEAKER_00: Now let's talk about the ratios because the ratios are where the real story lives.
• 4:58
  SPEAKER_00: The calcium potassium ratio is 40.25.
• 5:03
  SPEAKER_00: The optimal range according to Trace Elements, the lab that ran my HTMA, is 4.2 to 8.
• 5:09
  SPEAKER_00: My ratio is nearly five times the upper bound of optimal.
• 5:14
  SPEAKER_00: The sodium potassium ratio is 2.
• 5:17
  SPEAKER_00: The optimal range is 2.2 to 6.
• 5:21
  SPEAKER_00: I'm sitting just below the lower end.
• 5:23
  SPEAKER_00: But both ratios are pointing in the same direction.
• 5:26
  SPEAKER_00: There's not enough potassium relative to other minerals in my tissues.
• 5:31
  SPEAKER_00: And both ratios have the functional consequences we're going to talk through.
• 5:35
  SPEAKER_00: Here's where it gets really clinically interesting, and this is the part that I want you to really pay attention to.
• 5:41
  SPEAKER_00: The calcium potassium ratio is one of the most important ratios on the HTMA report.
• 5:47
  SPEAKER_00: Practitioners who work with this tool consider it one of the primary markers of thyroid function at the tissue level.
• 5:53
  SPEAKER_00: Why?
• 5:54
  SPEAKER_00: Because potassium plays two specific roles in thyroid physiology.
• 5:59
  SPEAKER_00: The first mechanism is the T4 to T3 conversion.
• 6:03
  SPEAKER_00: Your thyroid produces mostly T4.
• 6:06
  SPEAKER_00: That's the inactive form of thyroid hormone.
• 6:10
  SPEAKER_00: T4 has to be converted to T3, the active form, before your cell can use it.
• 6:16
  SPEAKER_00: Potassium is involved in the enzymatic processes required for that conversion.
• 6:22
  SPEAKER_00: When your potassium is depleted at the tissue level, that conversion becomes sluggish.
• 6:27
  SPEAKER_00: You can have adequate T4 production and still experience hypothyroid symptoms because the conversion step isn't completing efficiently.
• 6:36
  SPEAKER_00: Mechanism two is receptor sensitivity.
• 6:40
  SPEAKER_00: Even after T3 is made, it has to bind to receptors on your cells to do anything.
• 6:46
  SPEAKER_00: Potassium influences how responsive those receptors are, which means how readily the cell accepts the signal from thyroid hormone.
• 6:55
  SPEAKER_00: Low tissue potassium doesn't just slow down hormone production, it can reduce the cell's ability to respond to the hormone that's already there.
• 7:04
  SPEAKER_00: This is why someone can have a TSH that looks acceptable, a T4 that looks adequate, and still feel completely hypothyroid.
• 7:13
  SPEAKER_00: The problem isn't necessarily how much thyroid hormone is being produced, the problem may be the intracellular environment that's supposed to receive it.
• 7:22
  SPEAKER_00: When calcium gets high relative to potassium, calcium can have an opposing effect, essentially damp thyroid action at the cellular level.
• 7:33
  SPEAKER_00: The calcium-potassium ratio at 40.25 is the lab's way of saying your thyroid hormone may not be landing where it needs to.
• 7:42
  SPEAKER_00: My HTMA also identified me as a metabolic type slow one.
• 7:48
  SPEAKER_00: To explain what that means is important because it's directly connected to the potassium picture.
• 7:54
  SPEAKER_00: The slow metabolic type in HTMA refers to a pattern of slower oxidative metabolism, the rate at which your cells are producing energy.
• 8:05
  SPEAKER_00: Slow one specifically is associated with a tendency towards decreased thyroid activity and decreased adrenal activity.
• 8:13
  SPEAKER_00: The parasympathetic branch of your nervous system tends to dominate.
• 8:18
  SPEAKER_00: Think of it as your body's engine running in low gear.
• 8:21
  SPEAKER_00: It's not broken, but it's not firing at full capacity either.
• 8:25
  SPEAKER_00: When I looked at my trend bars on the HTMA report, the pattern made everything click.
• 8:30
  SPEAKER_00: Fatigue very high.
• 8:33
  SPEAKER_00: The foundational symptom of a slow oxidative metabolism.
• 8:37
  SPEAKER_00: Depression.
• 8:38
  SPEAKER_00: High.
• 8:39
  SPEAKER_00: The neurological picture of intracellular mineral depletion.
• 8:44
  SPEAKER_00: Hypoadrenia.
• 8:46
  SPEAKER_00: That was medium.
• 8:47
  SPEAKER_00: The adrenal output is diminished, which feeds the potassium loss loot.
• 8:53
  SPEAKER_00: And hypothyroid, also flagged because the calcium potassium ratio is the primary marker, and mine is nearly five times optimal.
• 9:02
  SPEAKER_00: That pattern right there is not four separate problems wearing different hats.
• 9:06
  SPEAKER_00: It's one interconnected system, and potassium depletion is threaded through all of it.
• 9:12
  SPEAKER_00: A low HTMA potassium doesn't just happen.
• 9:16
  SPEAKER_00: There are reasons.
• 9:17
  SPEAKER_00: The first one could be chronic stress.
• 9:20
  SPEAKER_00: The adrenal stress response prompts potassium excretion as part of the aldosterone sodium conservation mechanism.
• 9:29
  SPEAKER_00: Your body is trying to hold on to sodium during stress and potassium gets excreted in the process.
• 9:36
  SPEAKER_00: Do that long enough and tissue levels drop.
• 9:38
  SPEAKER_00: High sugar and refined carbohydrate intake.
• 9:42
  SPEAKER_00: Glucose metabolism requires potassium for cellular uptake.
• 9:47
  SPEAKER_00: Insulin drives potassium into cells, and while you're regularly spiking insulin, you're cycling potassium in and out of the cells in ways that can deplete tissue stores over time.
• 9:57
  SPEAKER_00: There could be an inadequate dietary intake.
• 10:00
  SPEAKER_00: Potassium rich foods include leafy greens, avocados, sweet potatoes, bananas, and beans.
• 10:07
  SPEAKER_00: People eating a standard American diet are almost certainly under consuming potassium.
• 10:13
  SPEAKER_00: But even people eating well can show low tissue potassium because of the stress and metabolic factors that we've already discussed.
• 10:20
  SPEAKER_00: Slow oxidation itself.
• 10:23
  SPEAKER_00: When cellular energy production is sluggish, the sodium potassium pump, which is the mechanism that actively moves potassium into cells, becomes less efficient.
• 10:33
  SPEAKER_00: Less efficient pump, less potassium inside the cell, slower metabolism, less efficient pump, it loops.
• 10:41
  SPEAKER_00: Diuretics in certain medications.
• 10:43
  SPEAKER_00: If you're on a diuretic for blood pressure and your doctor is never mentioned monitoring potassium, this is a conversation worth having.
• 10:51
  SPEAKER_00: Low potassium doesn't always announce itself as I am low potassium.
• 10:56
  SPEAKER_00: It shows up as a symptom cluster that looks like a lot of other things.
• 11:01
  SPEAKER_00: Again, the fatigue that doesn't respond to more sleep.
• 11:04
  SPEAKER_00: Not the just tired, and it's the kind of tired there when you wake up and it's still there by noon.
• 11:10
  SPEAKER_00: Muscle weakness or heaviness.
• 11:13
  SPEAKER_00: Doesn't have to be dramatic, not cramping necessarily, just a sense that your body is harder to move than it should be.
• 11:20
  SPEAKER_00: Brain fog and slow thinking.
• 11:22
  SPEAKER_00: This is the cognitive version of slow oxidation.
• 11:25
  SPEAKER_00: Constipation and sluggish digestion.
• 11:28
  SPEAKER_00: Your gut is muscle tissue.
• 11:30
  SPEAKER_00: Potassium depletion affects it the same way it affects skeletal muscle.
• 11:35
  SPEAKER_00: Depression, low mood, or emotional flatness.
• 11:39
  SPEAKER_00: Potassium is involved in nerve transmission and neurotransmitter signaling.
• 11:44
  SPEAKER_00: The neurological picture of low tissue potassium can look a lot like depression.
• 11:49
  SPEAKER_00: Cold intolerance, another hypothyroid symptom that connects back to poor T four T3 conversion and has reduced receptor sensitivity.
• 11:59
  SPEAKER_00: Heart palpitations are a regular heartbeat.
• 12:02
  SPEAKER_00: On the more serious end and worth checking if present, the heart is extremely sensitive to potassium balance.
• 12:09
  SPEAKER_00: Does anything on that list sound familiar?
• 12:12
  SPEAKER_00: Because for a lot of people with quote thyroid issues, the thyroid isn't the origin story.
• 12:18
  SPEAKER_00: The mineral environment the thyroid is operating in, or the environment the thyroid hormone is supposed to be landing in is the real issue.
• 12:27
  SPEAKER_00: A secondary flag was the sodium potassium ratio.
• 12:32
  SPEAKER_00: This is sometimes called the vitality ratio.
• 12:35
  SPEAKER_00: The optimal range is 2.2 to 6 minus 2, right below the lower end.
• 12:43
  SPEAKER_00: When this ratio is low, it suggests that the relationship between these two electrolytes is off in a way that affects energy and adrenal output.
• 12:53
  SPEAKER_00: A low sodium to potassium ratio is associated with fatigue, low vitality, reduced stress tolerance, and in chronic cases, adrenal exhaustion.
• 13:04
  SPEAKER_00: This is different from the calcium potassium thyroid connection.
• 13:08
  SPEAKER_00: The sodium potassium ratio is more about moment-to-moment energy availability, the acute capacity to mobilize resources in response to a demand.
• 13:19
  SPEAKER_00: When it's slow, the body's ability to shift into a higher gear is impaired.
• 13:24
  SPEAKER_00: So I've got a calcium potassium ratio telling a thyroid story, and a sodium potassium ratio telling an adrenal story, and both of them are pointing at potassium as a key player.
• 13:36
  SPEAKER_00: Friends, that's not coincidence, that's a pattern.
• 13:39
  SPEAKER_00: Here's what I want you to take from this episode.
• 13:42
  SPEAKER_00: Potassium isn't just about muscle cramps and bananas.
• 13:46
  SPEAKER_00: It's a cellular mineral that sits at the intersection of thyroid function, adrenal function, nerve signaling, and energy metabolism.
• 13:54
  SPEAKER_00: When it's depleted at the tissue level, the ripple effects touch almost every system in your body.
• 14:01
  SPEAKER_00: The blood panel doesn't see it.
• 14:04
  SPEAKER_00: That's not a failure of medicine.
• 14:06
  SPEAKER_00: That's just what blood panels are designed to do.
• 14:09
  SPEAKER_00: Monitor what the kidneys are keeping stable.
• 14:12
  SPEAKER_00: It's not designed to tell you what's happening inside the cell.
• 14:15
  SPEAKER_00: My potassium was 4.5 on my blood work.
• 14:18
  SPEAKER_00: Fine, completely fine.
• 14:21
  SPEAKER_00: My potassium was four on my HTMA with an optimal closer to 10, and a calcium to potassium ratio that was nearly five times the upper end of optimal.
• 14:32
  SPEAKER_00: The lab literally called the section hypothyroidism.
• 14:36
  SPEAKER_00: That is the gap between what a standard panel tells you and what tissue data tells you.
• 14:41
  SPEAKER_00: And my thyroid has been on the struggle bus for as long as I can remember.
• 14:45
  SPEAKER_00: Now I have a number that explains why.
• 14:48
  SPEAKER_00: That's the power of looking deeper.
• 14:50
  SPEAKER_00: You can't fix what you can't see.
• 14:53
  SPEAKER_00: And you can't see it if you're only using tools that look at the surface.
• 14:57
  SPEAKER_00: If this episode got your wheels turning about your own mineral status, I'd love to hear about it.
• 15:02
  SPEAKER_00: Come find me on Instagram or send me an email.
• 15:05
  SPEAKER_00: I'm always interested in the ways people are connecting their symptoms to the deeper biology.
• 15:10
  SPEAKER_00: And if you haven't had an HTMA done and you're curious, I'll have some resources in the show notes.
• 15:17
  SPEAKER_00: This is one of the most useful diagnostic tools I've encountered, and it's completely non-invasive.
• 15:23
  SPEAKER_00: Just a hair sample.
• 15:24
  SPEAKER_00: And it's worth knowing it exists.
• 15:27
  SPEAKER_00: The next episode we're going back into the mineral files, another number, another story, and another piece of the puzzle.
• 15:33
  SPEAKER_00: Until then, be curious, ask better questions, and trust that your body is trying to tell you something.
• 15:40
  SPEAKER_00: It just might need a better translation tool.
• 15:43
  SPEAKER_00: I'm Sandy Boone, and this has been the Braindump.
