Earlier quoted context omitted.
With a vegan diet, you need vitamin B12 supplements. Take a multi-vitamin supplement, some linseed oil for the essential fatty acids and maybe some mineral supplement if appropriate according to the blood test. You should do that anyway no matter your diet. Dr Garth Davis: Americans have become obsessed with Protein https://www.youtube.com/watch?v=XQCt3IhaUtU&feature=youtu.be...
Supplements are a scam industry and you should not be advising anyone to waste their time and money on supplements. https://arstechnica.com/science/2018/02/supplements-are-a-30...
From the linked article:
> Overall, multivitamins are not recommended for the generally healthy. There’s just no clear evidence to prove that they have any benefit. A 2013 analysis of 27 trials involving more than 400,000 people concluded that there was no clear evidence that they reduce cardiovascular disease, cancer risks, or reduce all-cause mortality.
This makes no sense.
You have a vegan diet to reduce cardiovascular disease, cancer risks, or reduce all-cause mortality.
You take vitamin supplements to prevent potential deficiencies.

The need for vitamins and essential fatty acids is scientifically proven.
Better safe than sorry. Multi-vitamin supplements are cheap enough.
