I have been taking a supplement called viviscal 'extra strength' for hair growth for about two weeks. I know some people who have seen good results with this supplement and decided to try it. A few days ago I developed a small, itchy (not extremely) rash on my jaw; I also broke out, especially around my chin.
I am pretty sure it is the viviscal, since its the only thing I changed; I also researched on the internet and found that a good few people have experienced similar symptoms (acne and even skin rashes) after using viviscal.
The ingredients are:
AminoMar C™ (Marine Protein Extract): 300mg
Acerola Cherry Extract (Vitamin C 30mg: 50% RDA*): 120mg
Horsetail Extract equivalent to: 30mg
It cannot be the vitamin C; I also doubt that its the horsetail, since I've never had allergic reactions to herbs before, and people who have reactions to horsetail are usually those sensitive to nicotine and nicotine-containing foods (such as nightshades), which I am not. I do not have a shellfish allergy (there is a warning about this on the box), have never had an allergy to any sort of seaweed or seafood, which I have always eaten a lot of.
I have read people speculating that the Marine extract's iodine content could be to blame for the rashes & breakouts. None of the other supplements I take have specifically added iodine, but I take fermented CLO, I eat shellfish a few times a week, wild oily fish almost everyday for breakfast, I use sea salt in food & cooking, I eat the occasional sea vegetable. Could I be getting too much iodine? What do you think?
And, if yes, should I simply switch to non-iodized table salt and scale down on shellfish while taking the viviscal? I don't really want to drop it (though I don't want to stop eating shellfish...they're so nutritious)
EDIT: full ingredient list: AminoMar C™ (Marine Protein Extract), Acerola Cherry Extract (Malphigia Glabra L), Microcrystalline Cellulose (E460), Horsetail Extract (Equisetum Arvense L.), Natural Orange Flavour, Magnesium Stearate, Hydroxypropyl Methylcellulose (E464), Glycerol.
I think the Microcrystalline Cellulose is just a bulking agent (aka cardboard); E464, however, according to google, has been known to cause allergic reactions...
