90% of people choose to read something in social media/internet written by someone with questionable background and qualification but don't want to read a book properly written by a fully qualified professional.
Let me remind you, Dr. Louis Ignarro is a Nobel Prize winner for medicine and also the person behind Herbalife products along with other really really good doctors like Dr. David Heber, Dr. Gary Small (go check out google search for these doctors background) And I have a chance to attend his teaching and also met him in person. Well... how many doctors in Malaysia do you know that is a Nobel Prize winner? Hmmm...? Actually none.
Dr. Louis Ignarro takes 2 Herbalife formula 1 shakes, 15 omega3 fish oil, 12 scoops of NW formula daily. He started running for marathon at age 64 and has completed 13 full marathon. (Each marathon = 42km, if you know...). Now he is 72 yrs old, still active, healthy and running for marathon.
See with you own eyes, feel with your heart, shut your ears to negativity.
That is why 90% of people in the world are follower. Only 10% are leaders, which are the successful and happy people.
