M.,
You may want to look at some other companies and compare them before you make up your mind. Compare the start up costs, how much you have to purchase every month, the percentage paid on downlines etc. Does the company have any peer-reviewed published research? These are questions you will have to anwer as you try to find others to join you.
Also spend some time thinking about why you want to do a home based business. Do you have a passion for nutrition and helping people? If not, you may want to look into something else. I can direct to some that my friends do that aren't nutrition based.
I am with the number one seller of natural supplements. We also have the best paying compensation plan (this is per outside sources.) We are also owned by a multibillionaire so we have plenty of money for science based research that allows us to have cutting edge products that other companies can't duplicate. If this interests you, you can listen to this 3 minute call: ###-###-####
One other piece of advice. If you do go with a MLM, don't try to recruit people away from another one they are already in.
Good luck. I hope you find the company that is best for you.
