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.
