Thiamine Tetrahydrofurfuryl Disulfide (TTFD)—also known as fursultiamine—is a highly bioavailable, lipid-soluble derivative of vitamin B1 (thiamine) designed to freely diffuse across cell membranes and bypass the rate-limited active transport systems required by standard water-soluble B1.

Verified customer reviews for expert-curated supplements and nutritional guidance by Stephen Heuer
"Stephen Heuer has extensive knowledge in helping you recover from any health challenge you are facing. I have had issues with my kidneys and Stephen has been invaluable in helping my health get better. You would do yourself a favor by getting a consultation from him for whatever health challenges you are facing."
"I've been enjoying the benefits of Synergy One and Green Meadow Whey for years now. At 71, they truly have made me feel 10 years younger — increased energy, better skin, rejuvenated hair growth, and increased libido being the primary benefits."
"I have used Synergy One for twenty years! I tried getting off it but noticed joint pain, so I got right back on. I will always use this product because it has raised my DHEA level and it seems to make my HRT work better."
"I highly recommend Steven for all his products. I was sick for 5 days and my husband gave him a call — he gave some supplements plus the Green Meadow Whey protein and the following day I was getting better and my energy went back to normal in a few days."
"After taking his recommended supplements, I've lost weight and improved gut health. The specific probiotics working in tandem with the recommended diet improved the health of my gut bacteria and made it extremely easy for me to keep from gaining the weight back."
"I had a hyperthyroid with shakes and fatigue — doctors wanted to put me on medicine for life. Steven put me on nutrition that completely healed my thyroid. The doctors could not believe the blood count and were shocked that another way of treatment was available."
"I have called on Stephen's expertise and knowledge in the field of nutrition many times over the years. He offers sound, practical advice and products that work. I highly recommend Synergistic Nutrition to my friends and family!"
