Gold utilizes a proprietary liposomal nutrient-delivery technology that improves bioavailability six-fold, while protecting the turmeric extract from degradation in the gut.


Unlike the powdered extracts used in other turmeric supplements, Gold uses an ultra-concentrated CO2 oil extraction that delivers all of turmeric's bioactive healing compounds.

No melatonin. No sedatives. Just better sleep quality.

The body and brain do the vast majority of their repair and restoration in Deep and REM Sleep stages, and increasing the time we spend in Deep and REM sleep each night is perhaps the single most powerful “lever we can pull” to improve recovery and slow the progression of biological aging. 


REST uses highly-bioavailable forms of magnesium, amino acids and botanical extracts - all supported by sleep research to relax the nervous system and increase time spent in Deep and REM sleep. This means you'll get to sleep quicker, recover faster and wake up feeling more refreshed.

    Really works for arthritic inflammation

    I’ve taken the tablets for over thirty days and I feel a difference with my knee soreness caused by arthritis inflammation. I do not feel the burning sensation when getting up to walk or from bending my knees. I’m an active person who bikes and gardens and I want to enjoy myself when I work or ride.

    No longer need injections

    I have been using the joint rejuvenation duo and it has really worked for the arthritis in my hands/fingers. I have skipped the usual prednisone injections done by my hand orthopedist. The swelling in my knuckles has gone down and stayed down. I am working on my yard, gripping golf clubs and I have done nothing different but add the Synchro products. I don’t often highly recommend something but this has worked wonders for my osteoarthritis in my hands.
