Most were health related & over time I found out why those products were superior:
As most of us have discovered that if you buy (let's say) a bottle of Aloe Vera from your favorite retailer, the FDA doesn't have the manpower to police 'How Much' Aloe Vera is really in the product.
Many of these MLM products work better (not because of secret ingredients, but) because they actually have more of the Active Ingredients in them. Without the middleman in the picture company's don't have to skimp on quality.
