Vitamin B12 – should I care?

Do you want to get happy with vitamin B12?

Vitamin b-12... do I need it?B12 is known to have a positive impact on mood, energy level, brain function, sleep and weight. Who doesn’t want improvement in these areas? Between pills, liquids and injections, it’s easy to get stuck wondering which approach is best to boost levels with supplementation. Optimizing your exposure to nutrients through food is always ideal. However, compromised digestion involving low stomach acid and absorption issues can prevent the body from utilizing B12.

Vitamin B12 is one of the most important nutrients we get from animal foods. If your diet is limited in animal products, you may be at risk for low levels. Deficiency is slow to present itself and symptoms can take 5-10 years to surface.

Symptoms of vitamin B12 deficiency


Depression or moodiness

Memory impairment

Chronic pain


Weight issues

Unhealthy hair and nails

Sleep disorders

Asthma or allergies

Numbness or tingling

Foods high in vitamin B12

Bivalves (clams, oysters, mussels) and liver are the highest by far!

Meat, fish, shellfish, dairy, eggs and anything else coming from an animal contain B12

Best ways to supplement with vitamin B12

Injections-These bypass the digestive system for immediate absorption

If you are consuming adequate amounts of B12 through your diet and exhibit signs of deficiency, your digestion may be the priority to address

Nutrition recommendation for Increasing B12

Have 3 oz of shellfish once per week

Consume high quality (organic and grass fed) animal products throughout the week
