I have been taking this supplement for about 3 1/2 years now. From my experience, this isn't something that you can take for 30 days and expect to see any lasting results; hence the negative reviews. Prior to taking this, I went to my doctor for a physical with a complete blood test. I am a 35 year old male who is extremely active, with a high stress job, who has had naturally high cholesterol since childhood (both HDL and LDL are high). Melanoma also runs in my family.
Since taking this supplement, without any other significant changes in activity/diet, my blood test results have extraordinarily improved. My HDL cholesterol stayed high (the good kind), and my LDL cholesterol dropped. My blood pressure is phenomenal and despite being in a very high stress career (law enforcement), people always make comments on how I look 10 years younger than I am.
The way my skin responds to sun exposure is also noticeably different. I didn't notice this until the 6 month mark. In my profession, during California summers, on days I forgot sunscreen, I almost always received a slightly sunburned face/forearms. That doesn't happen anymore.
All of these changes have been relatively subtle over a prolonged period of time. The long term benefits with this product have been outstanding. I highly recommend it.
Lastly, I have had some questions for this company during my years of using their product. All of my questions have received a response within hours of emailing them. Their response to questions/concerns is unmatched.
