Hi there and thank you for your question!
Nutritional supplements and personal care products such as Herbalife and Arbonne are not necessary to maintain a healthy lifestyle. There may be products that can support healthy living, but there are other factors that contribute to a healthy lifestyle, such as regular physical activity, quality sleep and stress management.
If you are considering to purchase these products (or if you know someone who is), I suggest consulting with your doctor or a qualified health professional before. Many nutritional supplements and products on the market are not regulated for safety or may not be appropriate or necessary for you.
I hope this helps!
