Vitamin B

B vitamins play important roles within the body individually but also collectively. It's best to always start with the entire B family, called a B complex and then add individual B’s if required afterward. B vitamins are water-soluble which means they dissolve in water. They are easily transported around the body but generally aren't stored which means you need a daily intake of these nutrients.


These healthy foods are good sources of B vitamins:

* Meat - red meat, poultry, and fish

* Eggs

* Improving digestion

* Increasing energy

* Improving nerve health

* Essential for good heart health

* Better moods and memory

B 7 : Biotin

* Energy

* Cell signaling and gene modification


B 9 : Folate (Avoid Folic acid forms of folate and foods fortified with Folic acid. Throw out supplements with this form in it. Methyl folate or folinic acid are the preferred forms.)

Yellow urine. This is expected with Vitamin B supplementation and stops when you stop supplementing. It is in no way dangerous; it's simply a product of B vitamin metabolism. Warning it can be fluorescent!


Medication interactions:

* Proton pump inhibitors such as Nexium block B12. Supplementation is needed

* Blood sugar regulating medication such as Metformin reduce B12. Supplementation is needed.

* B vitamins especially B6 and B12 can help reduce symptoms associated with chemotherapy treatment with drugs such as Capecitabine and Fluouracil. Supplementation is beneficial but speak to your cancer specialist first.


Fun Fact:

B vitamin was once thought to be 1 vitamin, but further research discovered it was multiple nutrients. At one point, they thought it went all the way up to 20.


Choline was once called B4 until it was discovered the body can actually produce small amounts of this nutrient and it lost its status as a vitamin. Choline is not produced in large enough amounts by the body and is still essential to consume daily. It is still found in most B complexes. It’s an essential nutrient for heart and brain health.


Inositol was B8 and was demoted for the same reason. Inositol is important for digestion, blood sugar regulation and cravings. There is also research connecting it to better thyroid function.


Other common nutrients once thought to belong here include: L-carnitine (B20), dimethylglycine (B16)
