Tocotrienols
The Superior Form of Vitamin E: 40 to 60× Faster Antioxidant Action Than Alpha-Tocopherol
Most Vitamin E supplements contain only alpha-tocopherol. Tocotrienols are the other branch of the Vitamin E family, and research consistently shows why that distinction matters. Three double bonds in their tail let tocotrienols move through cell membranes faster, suppress cholesterol production in the liver, and reach tissue that alpha-tocopherol cannot access.
Wellness Extract's Eannatto DeltaGold® uses annatto-derived tocotrienols: the only commercially available tocopherol-free source, standardized to 90% delta + 10% gamma with FDA GRAS status.
What It Is
Tocotrienols: The Other Half of Vitamin E
Vitamin E is a family of eight compounds split into two groups: four tocopherols and four tocotrienols. Both share the same chromanol ring structure but differ in the tail. Tocopherols have a fully saturated tail. Tocotrienols have an unsaturated tail with three double bonds, a small structural difference with large biological consequences.
Tocotrienols weren't isolated until 1964. Since then, over 2,000 published studies have examined their unique effects on cholesterol regulation, brain health, inflammation, and bone health, areas where standard alpha-tocopherol Vitamin E falls short.
Delta-Tocotrienol
Most Bioactive Isomer: Dominant in Annatto
The most bioactive of four tocotrienol isomers, with the strongest research behind cholesterol and anti-inflammatory effects. Delta makes up ~90% of annatto-derived tocotrienols, the highest delta concentration of any natural source.
Gamma-Tocotrienol
Anti-Inflammatory & Cholesterol Pathway Support
Dominant in palm oil, studied for NF-κB pathway suppression and cholesterol enzyme regulation. In annatto-derived tocotrienols, gamma makes up ~10% of the profile.

Tocopherol-Free Source
Why Tocopherol-Free Matters
Alpha-tocopherol can attenuate tocotrienol activity.[14] Annatto is the only natural tocopherol-free source, the same formula used in published human research.
How It Works
Why Tocotrienols Behave Differently in the Body
The unsaturated tail lets tocotrienols do things tocopherols cannot. Here's the mechanism-by-mechanism breakdown.
Antioxidant Speed
40–60× Faster Free Radical Neutralization
What the research found
Lab Study: Membrane KineticsTocotrienols get regenerated after neutralizing free radicals 40–60× faster than alpha-tocopherol inside cell membranes. Each molecule can neutralize more oxidative damage over time.[1]
Cholesterol
Suppresses HMG-CoA Reductase: Same Target as Statins
What the research found
Mechanistic StudyTocotrienols suppress HMG-CoA reductase through a post-transcriptional pathway, signaling the liver to produce less enzyme rather than blocking it. Alpha-tocopherol has no meaningful effect on this enzyme.[2]
Inflammation
Suppresses NF-κB, the Master Inflammation Switch
What the research found
Cell StudyGamma- and delta-tocotrienol directly suppress the NF-κB signaling pathway that activates genes for inflammatory compounds like TNF-alpha and IL-6. Alpha-tocopherol shows no meaningful effect at comparable doses.[3]
Brain Protection
Activates Neuroprotective Pathways in Dopamine Neurons
What the research found
Cell StudyDelta-tocotrienol protects brain cells through estrogen-receptor signaling that shields dopamine-producing neurons from damage, a pathway alpha-tocopherol doesn't trigger.[4]
Membrane Mobility
Moves Through Cell Membranes Faster Than Tocopherols
The unsaturated tail lets tocotrienols move around inside cell membranes instead of staying in one spot, reaching fat-rich tissue like the brain and heart that tocopherols cannot access as efficiently.
Cell Regulation
Influences Cellular Protein Recycling (Autophagy)
What the research found
Cell StudyGamma- and delta-tocotrienol influence how cells break down and recycle their own proteins, a process tocopherols do not show the same effect on.[5]
Research Findings
7 Researched Health Benefits of Tocotrienols
Every benefit below is drawn from published peer-reviewed research. Study types vary (human RCTs, systematic reviews, and mechanistic studies), and evidence quality is noted. Not intended to diagnose, treat, cure, or prevent any disease.
Heart Health
LDL Reduced by up to 25% in Human Trial
What the research found
Human Trial + Systematic Review (30 RCTs)A landmark trial found tocotrienols lowered total cholesterol by up to 20% and LDL by up to 25% over 5 weeks. Substituting alpha-tocopherol into the same protocol eliminated the effect. A 2025 systematic review of 30 RCTs (2,646 patients) confirmed tocotrienols' promise for lipids and inflammation.[6]
Brain Health
Stopped Brain Vessel Damage Progression Over 2 Years
What the research found
2-Year MRI Human TrialA 2-year MRI trial in adults with early brain vessel damage found daily tocotrienol supplementation stopped progression while the placebo group continued to decline. A 12-week RCT also improved non-verbal memory and sleep quality.[7],[8]
Inflammation
CRP, TNF-α & IL-6 Reduced in 24-Week RCT
What the research found
Human RCT: 24 WeeksAdults with type 2 diabetes taking delta-tocotrienol for 24 weeks saw significant drops in all three major inflammation markers vs. placebo. Mechanism: direct NF-κB suppression.[9]
Bone Health
Reduced Bone Resorption Markers in Postmenopausal Women
What the research found
Human RCT: 12 WeeksA 12-week RCT using annatto-derived tocotrienol (90% delta, 10% gamma) showed significant reductions in bone resorption markers and oxidative stress vs. placebo in postmenopausal women.[10]
Liver Health
Improved Liver Enzymes & Liver Fat in 24-Week Trial
What the research found
Human RCT: 24 WeeksDelta-tocotrienol twice daily produced significant improvements in liver enzymes, liver fat, and oxidative stress markers in fatty liver disease patients vs. placebo.[11]
Immune Function
Stronger Flu Vaccine Antibody Response
What the research found
Human RCT + Cell StudyTocotrienol supplementation for 2 months before flu vaccination produced a stronger antibody response vs. placebo. Delta-tocotrienol also suppressed NLRP3 inflammasome activation in immune cells.[12]
Aging Markers
Improved Telomerase Activity in 6-Month Trial
What the research found
Human RCT: 6 MonthsA 6-month RCT in older adults found the tocotrienol group showed improved antioxidant enzyme activity and higher telomerase activity, markers associated with cellular aging, vs. placebo.[13]
Dosage & Forms
How Tocotrienols Are Used
Tocotrienols aren't found in meaningful amounts in the average diet. Take with a fat-containing meal; tocotrienols are fat-soluble and absorption is reduced without dietary fat.
Natural Sources
Food Sources of Tocotrienols
| Source | Profile |
|---|---|
| Annatto seeds | Only natural tocopherol-free source; 90% delta, 10% gamma |
| Palm oil | Mixed tocopherols + tocotrienols; gamma-dominant |
| Rice bran oil | Mixed tocopherols + tocotrienols; alpha-dominant |
| Barley / wheat germ | Small amounts; too low for therapeutic effect |
Annatto is the only tocopherol-free source. Food sources provide insufficient amounts to reach research-level doses; annatto seeds used as food colorant are present in quantities too small to matter.
As a Supplement
Research-Based Dose Ranges
DeltaGold® available in 125 mg and 300 mg softgels. Take with a fat-containing meal.
| Dose | Usage |
|---|---|
| 100–200 mg/day | General antioxidant, cognitive function, immune response |
| 200–400 mg/day | Cholesterol management, anti-inflammatory, bone health |
| 400 mg/day | Used safely for 2 years in the MRI brain vessel trial |
Doses up to 3,200 mg/day have been studied without serious adverse effects in short-term trials. Consult your healthcare provider, especially if taking blood thinners or cholesterol medication.
From Seed to Supplement
Why DeltaGold®, and Why Tocopherol-Free
A 1996 study found alpha-tocopherol can blunt the effect of gamma-tocotrienol on HMG-CoA reductase. In mixed Vitamin E formulas, tocopherols may actively reduce the benefit of the tocotrienols present.

[14]Frequently Asked Questions
Everything You Need to Know About Tocotrienols
Tocotrienols are one of two natural forms of Vitamin E, the other being tocopherols, which is what most supplements contain. Three double bonds in the tail let tocotrienols move faster through cell membranes, suppress cholesterol-producing enzymes, and calm inflammatory pathways in ways that alpha-tocopherol does not.
Human trials show tocotrienols can meaningfully improve cholesterol markers; one landmark trial found a 20% drop in total cholesterol and 25% drop in LDL over 5 weeks. Tocopherol-free sources consistently show stronger results because alpha-tocopherol can attenuate tocotrienol's HMG-CoA reductase effect.[6]
DeltaGold® is a patented, standardized tocotrienol-only extract from annatto seeds, developed by Dr. Barrie Tan PhD. Unlike generic extracts from palm or rice bran, which contain tocopherols, DeltaGold® is standardized to 90% delta + 10% gamma with FDA GRAS status and confirmed tocopherol-free status.
A 1996 study found alpha-tocopherol can significantly reduce gamma-tocotrienol's HMG-CoA reductase effect. A 2001 human trial replicated this: substituting alpha-tocopherol into the tocotrienol protocol eliminated the lipid-lowering effect almost entirely.
100–200 mg/day for general antioxidant and immune support. 300–400 mg/day (split into two doses) for cholesterol or brain health. Always take with a fat-containing meal. Consult your healthcare provider.
400 mg/day was used safely for 2 years in the published MRI brain vessel trial. Doses up to 3,200 mg/day showed no serious adverse effects in short-term escalation studies. If taking blood thinners or cholesterol medication, consult a healthcare provider first.
