Do you feel cold, like, all the time? No matter the season, no matter how many layers you’re wearing?
While it’s easy to blame the weather or poor circulation, your body might actually be waving a red flag that something deeper is going on. If you’ve got cold hands, cold feet, or a constant chill you can’t shake, it’s time to stop brushing it off, especially if you’re also dealing with fatigue, hair thinning, poor digestion, or low energy.
Let’s talk about the real link between being cold all the time, your thyroid, and iron levels and how to fix it naturally without iron tablets, IVs, or side effects that wreck your gut.
The Cold Truth About Anemia & Hypothyroidism
Anemia and hypothyroidism are one of the most common causes of feeling cold. Your body needs iron to create hemoglobin, the protein in red blood cells that transports oxygen (and heat!) to every part of your body. When your iron is not used efficiently, your ability to generate, store, and circulate heat drops too. The problem is many women are being misdiagnosed with low iron, when in fact its not iron deficiency, but anemia of iron dysregulation.
Translation? You feel cold all the time because your cells aren’t getting enough oxygen or energy to warm you up. The iron is likely trapped in your tissues due to the iron recycling system being broken.
Hypothyroidism is a condition whereby your thyroid is receiving signals likely due to the mineral imbalance above of the broken iron recycling system, which by the way is vitamin A dependent, causing it to not work optimally. How does this make you feel cold? Well its job is to regulate body metabolism and heat production. Therefore if under-active, the body will remain cold, the thyroid will not output the thyroid hormone level required or the pro-hormone t4 will not convert to the active t3.
How Your Body Regulates Temperature (and Why It’s Not Working)
To understand why you’re freezing, let’s break down how your body normally keeps you warm.
- Hypothalamus – your brain’s thermostat. It senses your body temperature and signals when to heat up or cool down.
- Thyroid gland – this one’s huge. Your thyroid drives metabolism, and metabolism creates body heat. If your thyroid is underactive (hello, hypothyroidism), everything slows down especially your internal heating system.
- Iron and Blood Flow – red blood cells carry oxygen, nutrients, and warmth. Low iron (poor iron regulation) = poor circulation and energy.
- Adrenal and Liver Health – if these systems are stressed or sluggish, your detox pathways are congested, your hormones get out of whack, and your temperature regulation tanks.
If one part of the puzzle is out of sync, your whole system feels the impact and cold intolerance is often the first sign.
Cold Intolerance Isn’t Normal
If everyone else in the room is fine and you’re bundled up in three layers, you might have what’s called cold intolerance. It’s more than just “feeling the chill”, it’s a deeper symptom that something in your body is out of balance.
Common root causes include:
- Low thyroid function (especially T3!)
- Iron deficiency or anemia
- Adrenal fatigue
- Low body fat, post-birth control hormone shifts, or undereating
- Methylation or B12 issues
But here’s what’s really important: these symptoms are connected. Your thyroid can’t function optimally without iron. And your body can’t absorb iron properly without addressing gut health, inflammation, and liver congestion. It’s all connected. This is where functional nutrition comes in.
Why We Skip the Iron Tabs and IVs
- traditional iron supplements and IVs often cause more harm than good. Constipation, nausea, bloating, and inflammation are just the beginning. For many of my clients, these treatments don’t even raise their ferritin or energy levels in the long run.
- That’s because iron deficiency is rarely just about not getting enough iron, as your likely not low in iron, but have poor iron management. . It’s about:
- Poor absorption due to low stomach acid
- Gut dysbiosis or inflammation
- Liver congestion blocking proper conversion and storage
- Inadequate co-factors (hello copper, magnesium, vitamin A, B12, Folate)
- So we ditch the aggressive, synthetic iron and instead support your body holistically so it can absorb, regulate, and use iron the way it was designed to.
Natural ways to improve iron & thyroid metabolism
1. Ditch the Iron Tabs and balance minerals
Instead of high-dose supplements that upset your stomach, we focus on:
- Balancing minerals such as magnesium & copper to aid iron metabolism.
- Cofactors like retinol (vitamin A), and bioavailable B12/folate to help your body use the iron it’s getting
- Iron-rich foods like grass-fed liver, organic meats, shellfish, and pumpkin seeds
- Vitamin C-rich foods to enhance absorption (think citrus, berries, sauerkraut)
2. Support Your Thyroid + Adrenals
If your thyroid is sluggish, your whole metabolism slows and your body stops generating heat. I work closely with clients to support thyroid conversion (especially T4 to T3), balance adrenal stress, and rebuild mineral reserves using strategic nutrition and supplements.
3. Use Functional Testing to Find the Gaps
No guessing. We use functional blood chemistry, HTMA, GI Testing and symptom mapping to pinpoint exactly why your body isn’t holding onto iron and fix it from the root.
You Deserve to Feel Warm, Energized, and Alive Again
Being cold all the time isn’t “just how your body is” it’s a sign that your body needs more support. And the good news? You don’t have to rely on band-aid solutions like iron IVs or tablets that make you feel worse. With the right guidance and a root-cause approach, your body can heal.
If you’re in London or Online and looking for holistic support for anemia, thyroid issues, and cold intolerance, you’re in the right place.
