I am looking for people that have noticed an intolerance to lecithin and maybe generalized with soy also have vitamin c reaction. The reaction are very similar for myself that is why I group these supplements together. Symptoms caused are insomnia, irritability, overstimulation, anxiety. Lecithin is able to produce that with just 100mg while with vitamin C (ascorbic acid form) it happens when I increase dosage up to 3g. I am looking for people that have similar reaction to these supplements and have found out what is going on. Comments are also welcome. PS: I am posting in this section of the forum as it is most active and there are people that use this supplements as cofactors for methylation cycle supports, also for increased absorption.
