Tocotrienol Supplements: Are They Really Safe for You?
Estimated Reading Time: 6 minutes
Vitamin E tocotrienols supplements, linked to multiple health benefits, are often referred to as 'superfoods.' But are they actually safe to administer?
1922- the iconic discovery year of vitamin E. Herbert McLean Evans and Katharine Scott Bishop, two scientists from the University of California, Berkeley, discovered the biological function and chemical structure of tocopherols. It was quickly recognized for its antioxidant properties and its role in supporting heart health, immunity, and youthful skin.
However, the narrative shifted with the discovery of tocotrienols and its supplements, which emerged as a superior antioxidant. Let's explore the efficacy and safety guidelines of tocotrienol supplementation.
Wait, don’t you know the difference between different forms of vitamin E?
The Story Behind Vitamin E Tocotrienols
Tocotrienols, a natural form of vitamin E, were first discovered in 1964 in a rubber plant. The prominent discovery brought the attention of scientists and researchers across the world to explore the potential benefits of these other halves of tocopherols. Later, in the 1990s, the compound was further explored for its anticancer properties.
Then came the revolutionary breakthrough in 2002 by Dr. Barrie Tan, who identified annatto as a rich source of tocotrienols, free of tocopherols. His innovation, DeltaGold, an annatto-derived tocotrienol supplement, further strengthened the position of tocotrienols in the world of nutritional science.

What Do Global Regulatory Authorities Say?
Currently, the World Health Organization (WHO) doesn't hold any particular statements or guidelines about tocotrienol supplements. The Union Nation agency doesn't highlight anything about the safety standards or adverse effects of the tocotrienols supplements. On the other hand, the Food and Drug Administration (FDA) has evaluated the safety of tocotrienols.
FDA has granted DeltaGold tocotrienol supplement GRAS status, which has been expanded to Generally Regarded as Safe. In simple words, the GRAS status means tocotrienols are considered safe for human consumption, as intended. Despite the endorsement, the lack of specific guidelines from the FDA underscores the need for further research and clinical studies to evaluate the long-term safety of tocotrienol supplementations.

Evaluating the Safety Standards of Tocotrienols Supplements
In modern days, tocotrienol supplements are linked with cardiovascular health, strong bones, healthy liver, skin vitality, improved metabolism, and much more. The ideal dose of tocotrienols is based on the medical conditions and purpose of the supplementation. However, with fame comes the criticism.
How safe are vitamin E tocotrienols for humans? Or are tocotrienol supplements safe for regular use?
Adverse Effects of Tocotrienols at Higher Dose
According to Dr. Barrie Tan, who has taken tocotrienols more than anyone else on the planet, even 1000 mg of the compound per day won't do any harm to humans. There is no exact dose of tocotrienols classified by the FDA or WHO. However, a healthy adult can intake about 200-600mg of tocotrienols per day.
But what happens if, by any chance, someone takes a higher dose? In a rodent study, even the 2,500 mg/kg of tocotrienol per day, based on body weight, didn't show any significant toxicological effects. Clinical studies involving human participants indicated that 1000 mg/day of tocotrienols are well-tolerated at extended periods.
How Safe Is δ-Tocotrienol Oral Dose in Humans
δ-Tocotrienol supplements, due to their unique structure and bioavailability, have shown effective potential as an anti-carcinogenic adjuvant and certain other health benefits. But is vitamin E δ-tocotrienol safe when taken orally?
According to studies, tocotrienol doses (when given orally) range between 100 to 1600 mg when given to healthy adults once or twice per day for two consecutive weeks, having shown no drug-related adverse reactions. Instead, at safe levels, tocotrienol may support chemoprevention.
Is Tocotrienol Supplementation Safe for Postmenopausal Women
A woman's body undergoes hundreds of physical and hormonal changes postmenopause. Tocotrienols may support bone loss density and hormonal imbalance in osteopenic women without affecting quality of life.
According to a study, when postmenopausal osteopenic women were given 430 to 860 mg of annatto-derived, tocotrienol-rich extract per day for 12 continuous weeks, they showed significant improvement. Even in higher doses, the liver and kidney parameters remained within normal ranges. The supplementation doesn't impact physical activity, body composition, nutrient intake, or drug alteration, indicating its safety levels.
Tocotrienols Safety for Topical Uses
As an antioxidant, tocotrienols are 40-60 times more potent than tocopherols. Thanks to its greater bioavailability and deeper cellular penetration, tocotrienol is also an active ingredient in skincare and cosmetics. They boost skin collagen and may help reverse or slow skin damage because of free radicals.
According to the Cosmetic Ingredient Review (CIR) Expert Panel, tocotrienols are safe for use in cosmetic products. After considering critical factors like potential toxicity, skin irritation, and sensitization, it is observed that tocotrienols have no adverse dermal effects. On the other hand, the topical application of tocotrienols has shown a significant reduction in skin irritation, serum histamine levels, and dermal thickening, highlighting their ability as a skin supplement.
Tocotrienol Safety With Cholesterol Reducing Drugs
In the early 1980s, tocotrienols were first reported to have cholesterol-lowering properties by Asaf Qureshi and Elson in the Journal of Medicinal Chemistry. However, there is still debate about its safety levels.
A placebo-controlled clinical study investigated the safety and efficacy of tocotrienols in patients with hyperlipidemia. The participants who were given 200 mg of tocotrienols every day for 12 weeks reported no adverse effects. Unlike tocopherols, which don't react with LDL, tocotrienols may significantly reduce the low-density lipoprotein count in the human body.
Observed Side Effects of Tocotrienols
The current researchers haven't found any notable side effects related to using tocotrienols. A severe allergic reaction to annatto-derived tocotrienols is rare. But, as they said, prevention is always better than cure.
Some individuals might face rashes, itching, swelling, or dizziness. A more minor part of the population also reported shortness of breath with tocotrienol supplementation. Thus, if you are considering tocotrienol supplements, consider your medical experts and take them in optimal amounts.
Tocotrienols and Drug Interactions
The above studies support the idea that tocotrienol supplements are safe for all individuals. However, the question now turns to the activity of tocotrienols with other drugs and medications. Do tocotrienol supplements have a synergic or antagonist effect when combined with other drugs or therapies?
Antagonist To Certain Drugs
Vitamin E tocotrienol, because of its unique structure, may interact with certain drugs, altering their mechanism and effects. In clinical studies, high doses of vitamin E supplementation have interacted with anticoagulant drugs like aspirin and warfarin.
It also inhibits the mechanism associated with tamoxifen and cyclosporine. However, the good news here is that even in the patients following other medications, the ideal to medium dose (<300 mg/day) of the supplement appears safe, resulting in no significant adverse drug interactions.
Synergistic to Chemotherapeutic Agents
Tocotrienol supplements are also linked with anticancer therapies. Preclinical studies suggest that tocotrienols may complement certain standard anticancer approaches by supporting oxidative balance and cellular function. With proper research and trials, in coming times tocotrienols may be a valuable adjunct.
What is the exact mechanism behind this? It may be because tocotrienols reduce cellular oxidative stress. This influences the cell signaling pathways and gene expression. However, further clinical studies are necessary to confirm these benefits and establish safe and effective dosages.
Final Takeaway
Tocotrienols, indeed a potent antioxidant, also have promising health benefits. With no or minimal risk factors associated, they can be considered safe for most of the population. After medical consultation, you can add tocotrienol supplementation alongside your medication to maximize the biological results. However, one thing you must acknowledge is that tocotrienol supplements aren't a replacement for standard medical care.
