Hi, I used 3g of chlorella/day which contains 100% of Reference Daily Intake (RDI) of vitamin B12.
When I received my blood results (circa 7 months ago) the medical practitioner seemed suprised by my — to them seemingly unexpected — b12 scores.
I can fully recommend 3g of chlorella powder a day. I mix it with 3 grams spirulina, ~3g salt, some lemon juice, add cooked water to it and drink it as first drink after rising. The salt and lemon makes it taste more pleasent to me.
P.S. Past week I did an extended mix where I added lime juice, olive oil, and agave syrup. Somehow I truly enjoyed the taste. 😀 🫀 💚
