Hey all, I'm new here.
I just wanted some guidance really or maybe just even opinions on what people believe the safest supplement to be out of the three mentioned in the topic title. I'll briefly go over my thoughts and I hope to see which one you would feel the most comfortable taking, I don't know, some of you may even be taking one of the supplements already.
I have been taking 5-HTP for 5 days now but I'm really uncomfortable with the heart valve damage issue and it's really making me want to stop already as I'm becoming paranoid. I think taking 50mg daily (ignoring the issue of whether its coupled with vitamin B6 here) of 5-HTP in the long-term might be too risky. Yet the annoying thing is that there is no evidence of this or long term studies with compelling results saying it causes such damage, at least according to my knowledge anyway. As for Peak-X, well that is a slight worry, but I have seen Peak-X free brands like Doctor's Best and also there is no definite answer on whether Peak-X serious disorders.
As for tryptophan, I think I could feel more uneasy about taking this than 5-HTP, all because of this EMS business. Yes I know it was ages ago concerning a Japanese company altering the bacteria fermentation process but it still makes me worry. EMS sounds devastating and even with NOW Foods' Tryptophan which is USP grade and supposedly free of Peak-E and microbial contaminants I would still have concern. There is also the issue of it raising the incidence of bladder cancer, and maybe even something to do with increasing the risk of type 2 diabetes (I'm sure I've seen that somewhere). EMS is probably the biggest concern though, as I'm sure there has been debate also that it could well have been the tryptophan itself that caused the onset of EMS in susceptible people.
Lastly, Rhodiola Rosea seems the safest with the least serious potential side effects, well from what I can find anyway. But who knows, maybe enough research hasn't been done on it. Because it was a while before a study claimed that SJW could increase the risk of cateracts.
I look forward to hearing your opinions, on whether the above are rational worries or whether I'm just over-reacting lol, honestly why can't everything just be absolutely safe!!
Thanks
