When it comes to meeting our daily nutrient needs, B-12 ranks among the most important elements needed for the human body. Our bodies require over 70 nutrients to not only survive, but thrive. It is nearly inevitable that at some point we will lack certain nutrients. B-12 is one of the most common that often goes unnoticed. Thankfully, there are sources of nutrition of this critical nutrient. The B-12 in seafood is a commonly overlooked source for those that prefer not to eat meat too often.
It is nearly inevitable that at some point nutrient deficiencies will form. The human body is truly incredible and can make up for deficiencies for many years. But if left ignored, these deficiencies take an increasing toll on our overall level of health. More times than not, multiple deficiencies are present and this is when health disorders begin to occur.
The core of disease is usually based in either toxicities or deficiencies. Oftentimes, it’s a combination of both, depending on the specific toxins and deficiencies. Since the medical system doesn’t routinely include nutrient testing, it’s critical that we take matters into our own hands. Moreover, if deficiencies are prevented before they get out of hand, many conditions could be prevented as well.
The Widespread Problem of B-12 Deficiency
B-12, also known as cobalamin, is a very complex and multifaceted nutrient. The roles of B-12 are specified, focused, and extremely adaptable. In the past it was believed that deficiencies were somewhat rare. The estimates that have often been published were usually suspiciously low. Thanks to improved research and modern testing, we now know that the real number is much higher. It is estimated that around 40% of the population is either somewhat low or deficient in B-12.
The number of people not getting an ideal amount of B-12 is even higher than that figure. This is somewhat alarming because of the importance it has inside the body. Low levels have been linked to depression, fatigue, poor cognitive function, anemia, high homocysteine levels, shortness of breath, heart palpitations, pin-like tingling sensations, problems with vision, weakened DNA, poor balance, ringing in ears, and much more. B-12 is needed for incredibly important tasks such as:
– Synthesis of DNA and RNA
– Red blood cell production
– Proper brain function
– Energy Production
– Nerve cell function
– Cellular metabolism
– Removal of cyanide in the body
– Homocysteine control (high homocysteine is implicated in cardiovascular disease)
– Synthesis of neurotransmitters
Seafood As a Source of B-12
Plants are rich in many amazing nutrients, but are usually lacking adequate levels of B-12. For those that may not want to eat meat several days a week, the B-12 in seafood is surprisingly high. Not all forms of seafood contain enough B-12 to positively influence deficiencies, but below are some of the richest sources.
The Richest Seafood Sources of B-12: Clams & Mussels
This isn’t commonly known, but clams and mussels are absolutely bursting with B-12. They’re one of the most B-12 rich sources in the entire world. A mere 3 oz serving contains around 3000-3500% of the daily value! Of course, the daily value for B-vitamins isn’t what many people should be going by with deficiencies. Consuming a small amount of clams or mussels 3-4 days per week is one of the most economical ways of increasing B-12 intake.
Mackerel
Mackerel is another fantastic source of B-12. A 6 oz. portion of mackerel contains around 1300% of the daily value of B-12. It also contains omega 3 fats, B-6, magnesium, selenium, niacin, phosphorus, vitamin D, and more. Atlantic mackerel is lower in heavy metals when compared to King and Spanish mackerel.
Diet Isn’t the Only Cause of Deficiency
While diet isn’t the only culprit in B-12 deficiencies, it’s usually an influencing factor. There have been studies showing that deficiencies may also have some genetic roots. There may also be a lack of a specific protein known as intrinsic factor, which causes poor absorption.
In cases of low intrinsic factors, there are a few supplements that supply this needed co-nutrient to help absorb more B-12 from food. Low folate levels can also hinder B-12 absorption. Taking these steps can help to satisfy one of the most important and widespread deficiencies in the world.
