It is commonly just B12 that you really might want to supplement. B12 is not made by animals either. It is dirt from the ground. Since we sanitize most of our food it can be hard to get unless you are eating b12 fortified foods or taken a supplement. You don’t need much though. Just a small weekly serving is enough for most people.
However, you can get blood tests done to check your levels and I believe it is commonly thought that people have YEARS worth of B12 stored up before becoming deficient.
Also D3 if you are not outside 30-60 min a day depending on the sunshine level at your location.
Iodine if you aren’t using iodized salt.
and that’s it. Everything else can be gotten in adequate supplies from plants and whole foods.
sounds delicious. thanks for sharing!
