Today’s Presenter Barrie Tan, Ph.D., earned his bachelor’s degree in chemistry and doctorate in analytical chemistry at the University of Otago, New Zealand, and later became a professor of chemistry and food science/nutrition at the University of Massachusetts, Amherst. His research expertise included lipid-soluble materials such as carotenoids, tocotrienols/tocopherols, CoQ10, omega-3s and cholesterol. He was the first to introduce tocotrienol’s benefits to our nutrition industry. He founded American River Nutrition Inc. in 1998 and developed the first ever tocopherol-free tocotrienol product derived from annatto beans. Today, the focus of his research is on phytonutrients that have an impact on chronic, degenerative and cancer diseases.

• Superstar? • Under-dosing?
• Shocking!

Vitamin E – Antioxidant and Nothing More.1 Much higher doses of 3,200IU (2,100mg or 2.1g!) of Vitamin E needed to suppress oxidation in humans.2 95% of Americans do not even have enough of the 12mg RDA, the proclaimed adequacy to prevent a deficiency syndrome.3,4 5

Tocotrienol Trumps Tocopherol
• Both tocotrienol and

BUT…. • Only tocotrienol has been shown to: – reduce cholesterol – manage diabetes – inhibit cancer

Shorter farnesyl tail

© 1/09
Tail Discussion (1) • Shorter tail = less anchor = move faster = greater reach to all membranes • Trienol Tail – Flip-flops less – Waggles less – Wobbles less
• Conclusion: Shorter tail moves faster & better to protect a much larger cell membrane area (50x better) 9

© 1/09
Head Discussion (2) • Less stuffed head (less methyl groups) = smaller head (desmethyl head) = access to action • Desmethyl Head – Protracts (bobs and floats) – Recharges faster – Treat damage faster
• Conclusion: Smaller head arrests/seals damaged membrane efficiently (50x better) 10 * Packer, L., S. U. Weber, et al. (2001).

Desmethyl Tocotrienols

• Fully or C-5 methylated (less or non-potent) – Alpha-T3 and beta-T3 δT3

1992 – Hypocholesterolemic Activity of Tocotrienols Specified (Bristol-Myers Squibb) • • • •
Delta- and gamma-tocotrienols are most active Alpha-tocotrienol is 5-30 times less active Alpha-tocopherol is inactive When combined, only delta-tocotrienol and gamma-tocotrienol work best synergistically

Cholesterol Reduction Timeline (2) 2006 – Dose-Response Impact of Tocotrienols in Animals • Which tocotrienol works better? • Delta-tocotrienol worked best, followed by gamma-tocotrienol • Potency of cholesterol-reduction is delta > gamma > TRF > alpha • Alpha-tocopherol is inactive 2006 – Cholesterol-Reducing Mechanism of Tocotrienol Confirmed (U. Texas) • Unequivocally confirms original Bristol-Myers Squibb study of 1992 • Tocotrienol blocks and degrades the HMGR enzyme protein • Only delta- and gamma-tocotrienol decreases HMGR reductase effectively, while alpha-tocotrienol is 10-fold less active • Only delta-tocotrienol blocks HMGR • Alpha-tocopherol does not work • Endorsed/acknowledged by 1985 Nobel Prize winners for the 18 discovery of the LDL receptor, Goldstein & Brown

Anti-Angiogenic Properties of Tocotrienols (1)
• Angiogenesis is important in tumor growth, diabetic retinopathy, rheumatoid arthritis, and psoriasis • Delta-T3 is most active; without toxicity • Alpha-T does not work • May work better with omega3, resveratrol, EGCG, capsaicin • Possible mechanisms: – VEGF, FGF, EGF – Telomerase – Hypoxia * Nakagawa, K., T.

• In tumor-implanted mice: (A) Without Delta-T3 – Neovascularization (B) With Delta-T3 – Inhibition of neovessel formation
• Anti-angiogenic effect of Delta-T3 attributable to
Neovascularization
– Inhibition of growth factors (e.g. vascular endothelial, fibroblast, epidermal) – Generation of ROS and apoptosis in tumor

Interferences by Alpha-Tocopherol in Mammary Cancer Cells • Interferes with estrogen (+ve & –ve) cancer • Antagonizes tamoxifen’s ability to block estrogen +ve cancer by 1,000x • Blocks completely the powerful effects of tamoxifen on estrogen –ve cancer • Argues for tocopherol-free desmethyl tocotrienol (delta-T3 & gamma-T3) usage

Tocotrienol and Melanoma
• Desmethyl tocotrienols suppress tumor growth in vitro and in vivo • Via suppression of HMG CoA reductase activity • Tumor suppression: – delta-T3: 50% – delta-T3 + Lov: 60%
• Combo is nontoxic to animals at tumor-suppressive doses with T3:Lov of 5:1 • T3+Lov combo has already been successfully shown in hypercholesterolemic patients

Multifaceted Mechanisms of Tocotrienol
• Much higher cellular and tumor bioavailability than tocopherol (50100x), especially delta-T3 and gamma-T3 • HMG CoA reductase suppression • Pro-apoptotic effects • Anti-angiogenesis (growth factors, hypoxia) • Genetic regulations
