Preventing Brain Loss with B Vitamins?

One week on a plant-based diet can significantly drop blood levels of homocysteine, a toxin associated with cognitive decline and Alzheimer’s disease. Without vitamin B12 supplementation, though, a long-term plant-based diet could make things worse.

time after time whole food plant based/vegan proves to be the healthiest way to go, I am so glad I saw the light! I am going to age so well! people already say I look ten years younger than I actually am!

I notice in both trials they were using Folic Acid and not Folate,
in your video 'Can Folic Acid Be Harmful?' you describe how Folic Acid supplementation can be detremental to health,

Beans and Greens ftw :)

Wonderful video! Also if a person has genetic methylation issues they may need 5-MTHF (activated B9) to help reduce homocysteine.

Dr. Greger, thanks for your videos, they are insightful and important for us concerned and curious about health. I've been a vegetarian for 22 years and recently turned vegan. In accordance with this video vitamin B12 was mentioned as an important supplement in preventing this harmful disease. However, it made me curious as to how often a vegan should take this vitamin (daily, once a week, etc) to receive it's minimal (or maximum) benefit. If you have any suggested literature or advice in relation to this that would be most helpful. Thank you.

Went to the local Kroger store Thursday night 7/17/2015. They didn't even have a can of peas on the shelves. Legumes are good and good for you but they are taking up less and less shelf space.

I wonder if anyone here is aware of all the toxic substances that are used in the making of vitamins and particularly B vitamins and/or what the formulas are? I will give you a little hint. It is NOT good. It always helps to know what you are putting in your body and especially if it's on a daily basis.

so now... whats the difference between suplementing with pills and injections. I sort of dont want to jab myself... Hope that pills are ok to use

Hi, I was just wondering if you can get too much B12? I was taking a B Complex and an additional B12 and my levels were around 1300, so my Naturopath told me to stop taking the B12. I am over 60 and vegetarian so I was wondering if it is really a good idea to discontinue the B12, since age can be a factor in absorption.

This means should we take a b vitamin complex supplement

Alcohol abuse shrinks the brain as well.

Anyone here got opinions on the best sources for B vitamins in general? They don't really seem to be present in a lot of the foods I eat :s

[tlmanker]

Why dont you do a video on plant based oils which are the cause of inflammation and most of the diseases of the last 100 yrs?

[ramanvij]

Should we be taking folate supplements

[BeyondUnknown]

What is the minimum intake of greens and legumes?

[levingthedream]

Dr.Greger, would you consider doing a video about CBD-oil?

[youtubeplanting]

"...and come out with the best levels of all!"

Methylcobalamin, B12 is probably the most nutritious form of B12.
