Where is the B12 coming from in the tempeh though? Has to get cobalt from something.

I wonder about the mushrooms and algae and nori too. I doubt any of these foods are available where I live.

I've been told repeatedly that there are no plant sources of B12 outside of not washing the sand off your plants.

Why can't you just take a B12 supplement?

The element has a medium abundance but natural compounds of cobalt are numerous and small amounts of cobalt compounds are found in most rocks, soils, plants, and animals.

Since B12 is measured in micrograms the bacteria probably don't need much of it. Even tobacco smoke contains cobalt.

Would be nice to have B12 in plant-based food here! I get pretty severe effects from deficiency.

If you already have a deficiency, you need treatment, not fortified foods.

Get methylcobalamin injections from a pharmacy. You can get them over the counter in most countries except the US, where they're illegal unless administered by a licensed practitioner.

Inject into your thighs (into a muscle) daily for a week and then monthly until you recover. Make sure to pull back on the needle slightly to make sure you didn't hit a vein. Choose a different injection site each time.

Vitamin B12 Deficiency - 1000 mcg of methylcobalamin injected intramuscularly once daily for up to ten days. Depression - 1 mg of methylcobalamin injected intramuscularly once per week for four weeks. Cognitive Function - 1000 mcg injected daily for five days, followed by a monthly injection of 1000 mcg for five months.
