For example directory submission in a few quality health-related directories, submit your website to OTHER directory and try not to tell about what you are going to SELL!
Article marketing... well, it could work if you write about general health and try to tell about a way to do something with health for example (for people to be healthy) or something like this...
Forum marketing, I don't think it will work.
Blog commenting, with 3 words -> DON'T USE IT! Social Boomarking, most websites will NOT accept your website.
Social Media... You could get your website and even account banned -> so NOT recommened.
Hope I helped!
