I’m very pleased with my phone- in order. Very polite person on the phone and also very helpful in helping me with my questions Thank you.

I have been a customer since Spring of 2009. Only needed to contact customer service twice. Their response was prompt and resolved the issue. Great products and great service!

Dr. Wong's office always professional, cordial and polite.

New site works great organized simply

Dr. Wong’s is very knowledgeable in a wide range of health issues, and his advice is very useful. It has saved me from unnecessary surgery on 2 occasions. He has designed and personally uses the supplements that he offers to the general public. His protocols on how to use are very specific, and they work. Personally I have been using his Zymessence and Magscorbate for the past 15 years, and plan to continue. I will probably be adding 3 other products after I try them.

Products are very effective.

Absolutely delivered what I was hoping for…exceptional! My 20 year-old son had to have his tonsils and adenoids removed a friend suggested Dr. Wong‘s enzyme. I ordered late so my son was on hospital prescribed meds for the first three days once Dr Wong’s enzymes arrived my son was able to get off of all prescriptions, he felt way better and he was able to eat real food!!! Recovery was cut in half. So grateful for Dr Wong!

I truly appreciate how quickly Dr. Wong responds to questions that I offer him. Amazing!

Quite well!
