Sodium Function, Toxicity, and Effects of Deficiency

What do you need to know about Sodium?

Sodium (Na) is the fundamental extracellular electrolyte in the human body.? In other words, it is the most common electrolyte found outside cells.? Interestingly, Sodium makes up about 2.8% of Earth’s crust and it is the sixth major element on the planet.? This means that we can find sodium in the natural world.? It can offer an extra free electron but isn't needed for enzyme functions.

Na is essential for your life.? It does help your body in one of the most crucial functions: regulating fluid balance.? Your body is 60-70% made up of fluid.? Now, imagine the important role of Sodium in your daily life!

In this blog, you will have a deep dive into Sodium.? But first thing first…

?

Why is Sodium an essential electrolyte?

The word worthy of your attention here is ‘electrolyte.’? Electrolytes are electrically charged minerals that profoundly impact how your body functions.? They balance electrical charges inside and outside our cells.? This balance is crucial for the proper functioning of your nerves, muscles, vital organs, and every single cell in your body.

Sodium (Na) is the most important among these 4 major electrolytes.? It is indispensable and takes the lead in regulating fluid balance.? It ensures that cells receive the hydration they need which is crucial in that it directly affects our blood pressure.

Na is highly water-soluble.? It is a great solvent in your body that is responsible for dissolving chemicals and minerals such as calcium, magnesium, zinc, iron, copper, and more.

So, Sodium is the multi-tasker that aids in nerve impulse transmission and directing muscle contractions, including the most vital one: your heartbeat.? When the cellular level gets low enough, palpitations will occur as your heart is unable to electrically regulate the beats.

What are the dietary sources of Sodium?

The main source of Na is table salt.? This iodized form is NOT good for you. Yes, the one you used in almost every second dish. The minute amount of iodine added does not make up for the amount of deficiency the common person experiences.?

Iodized salt contains an anti-caking agent such as sodium aluminosilicate or calcium aluminosilicate as well as fluoride salts.? You do not want to eat aluminum and fluoride.

The RDA for iodine is 150 mg a day for Americans, whereas the Japanese minimum recommended daily allowance is 1,500 mg.? Just compare longevity statistics and thyroid issues to see how beneficial real iodine can be.

Na is the primary mineral (although subpar in form) gained through modern foods like pizza, processed chicken, bread, rolls, and fast foods.? But as you know, fast foods and other processed foods bring more harm than good, so I won't advise you to gain sodium from these resources.? Use a mineral-rich form like Real Salt, Redmond Salt, or a 99% plastic-free form like Colima for trace minerals.
