Spirulina is not a good source of choline. You'd need about 6 cups of it per day to get it. I think the person commenting is just interested in spirulina itself and is misguided about its benefits.

The studies listed as part of this thread show people taking 3-4 grams per day for 8 weeks... that's less than 1% of choline RDI. Not very relevant to our conversation.

I agree, from what I have found in studies for anyone that have autoimmune diseases or are on heavy medications, it can make them worse. Thats been the main area that have been the negative impact of the supplement.

It's something that should be watched as you take it and/or discussed with a doctor if you are dealing with other health conditions.
