Pure methylfolate would be the best idea. Taking folic acid that cant be efficiently converted can displace methylfolate and cause a functional methylfolate deficiency. I found the PERFECT b sup for you
Yes, it boosts intracellular immune function by boosting intracellular glutathione levels in immune cells. It is an antioxidant. It also has antiviral properties, quite potent actually.
Swollen lymph nodes/glands are swollen because they are inflamed, because of infection. Lymph nodes play an important role in immune function. The body stages immune cells at specific locations, bottleneck or filter locations if you will, and the lymph nodes are a big part of that. Where there is junk, there is an active immune system. Hence the term lymphocytes. When the immune system isnt capable of knocking out whatever infection is present, chronic inflammation persists.
Tryptophan comes before 5-HTP in the pathway to serotonin. I referred to 5-HTP in terms as a source of tryptophan that could be converted “backwards” into tryptophan. Side effects are less with tryptophan than 5-HTP. I wonder too if those effects might have been just start up. Might help to titrate anything like that too.
