Fatigue. This would be the number one health complaint I see.
As a Nutritionist, our goal is to find what the underlying cause is to that fatigue and address this for long term benefits and resolution.
Low vitamin B12 levels can be behind our fatigue, as this nutrient is
required to produce energy at a cellular level in our body.
B12 deficiency is common as we must obtain it from sufficient animal products in our diet, so many people who eat no to little meat can easily not be getting enough B12. We also rely on good digestion, as we need to break down these proteins properly to absorb this nutrient in our small intestine.
What B12 does in the body
* Produces energy and helps the body metabolise proteins, carbohydrates and fats.
* Essential to cell growth and replication, i.e. DNA synthesis.
* Supports a healthy nervous system and cardiovascular function, it’s required for red blood cell formation.
B12 Deficiency Signs
* Fatigue (both physical + mental)
* Poor memory
* Shortness of breath
* Numbness or tingling
* Pale skin/face
Causes of B12 deficiency
* Vegan or Vegetarian diets
* Conditions of the small intestine such as Coeliac Disease, Crohn’s
Disease, SIBO or parasites.
* Excessive alcohol intake
* Acid-reducing drugs like Nexium or Somac.
We require sufficient stomach acid to absorb the B12 from foods.
Diagnosis
Some of the risk factors listed above along with any symptom signs may give us an indication. Then we always use pathology results to confirm any nutritional deficiencies.
As Nutritionists, we like an optimal level of Vitamin B12 of around 500-600pmol/L. And if you’re pregnant your B12 levels definitely need to be at the upper end so there’s ample supply for your growing baby as B12 is
required for DNA production!
Addressing B12 deficiency
* Increase consumption of B12 rich foods:
red meat, seafood, poultry, dairy and eggs.
* Address any digestive issues which may be causing malabsorption.
* Use therapeutic supplementation if required to restore adequate levels.
If you suspect you may have any nutritional deficiencies like B12, then
always consult a Nutritionist or health practitioner for advice.
