HelloPharmacist Scorecard of Tocotriene Ultra by Premier Research Labs
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Low disclosure
Tocotriene Ultra is a powder with three active ingredients. Stabilized rice bran and organic brown rice protein provide nutrients and compounds that may support heart and digestive health.
Inulin is a prebiotic fiber that feeds beneficial bacteria in your gut. The product contains no other inactive ingredients listed.
Does it work?
Strong evidence
The evidence for what this product does varies by ingredient. Stabilized rice bran is possibly effective for improving cholesterol levels (dyslipidemia) and possibly ineffective for colorectal cancer risk.
We don't have reliable evidence on whether it helps with hair loss (alopecia areata). Brown rice protein is possibly effective for food allergies, but evidence is insufficient for muscle soreness or strength.
Inulin is possibly effective for weight management, constipation, and blood sugar control (diabetes), though evidence is insufficient for liver health or iron-deficiency anemia.
How safe is it?
Well-documented data
Rice bran and rice protein are generally well tolerated, but both can cause digestive side effects—abdominal discomfort, bloating, gas, and irregular bowel habits—especially when you first start them or use higher amounts. Rice bran and rice protein can also trigger allergic reactions in some people, including rashes, itching, swelling of the throat (angioedema), and in rare cases anaphylaxis.
Inulin commonly causes gas, bloating, and cramping, especially at doses over 30 grams, though anaphylaxis to inulin-rich foods has been reported rarely. Concentrated supplements of rice bran and rice protein have not been well studied in pregnancy or while breastfeeding—talk with your doctor or pharmacist for personalized advice if you are pregnant or nursing.
Meds to double-check
Moderate interaction found
Check any ACE inhibitor blood pressure medication you take—rice protein in this product may add to its blood-pressure-lowering effect. Also double-check any antidiabetes drug with your pharmacist, since inulin might theoretically increase low blood sugar risk, though the evidence is unclear.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
This product may help with cholesterol levels and digestive health, but if you take blood pressure medication or diabetes drugs, check your exact medications with the tool below first. Start with a lower dose to see how your digestive system handles it.
If you have a history of rice or inulin allergy, skip this product and talk to your pharmacist.

Tocotriene Ultra by Premier Research Labs Drug Interactions
HelloPharmacist Interaction Report
Tocotriene Ultra by Premier Research Labs contains three active ingredients, and one of them—organic brown rice protein—has a documented interaction with a common blood pressure medication.
The rice protein in this product can theoretically increase the effect of ACE inhibitors (blood pressure drugs like lisinopril or enalapril), potentially lowering your blood pressure further than intended. This interaction is rated Moderate, though it's based on lab and animal research; human studies haven't confirmed it yet.
Read the full breakdown — every affected drug type, severity by severity
Inulin, another ingredient here, may theoretically increase the risk of low blood sugar (hypoglycemia) if you're taking antidiabetes drugs—though the evidence is mixed on whether inulin actually lowers blood sugar in people. We have no interaction data on file for stabilized rice bran.
Altogether, these interactions span 108 individual medications. If you take any blood pressure medication or diabetes drug, run your exact medication through the checker below before you start this product.

For each ingredient in Tocotriene Ultra with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Dietary Fiber
Carbamazepine (Tegretol)
Theoretically, black psyllium might reduce the effects of carbamazepine and increase the risk for convulsions.
Theoretically, black psyllium might reduce carbamazepine absorption. A preliminary study using blond psyllium reported decreased carbamazepine bioavailability due to binding of the drug to psyllium, as well as reduction of available fluid in the gut for dissolution of the drug. This interaction may also occur with black psyllium.
Lithium
Theoretically, taking black psyllium at the same time as lithium might reduce lithium absorption.
The fiber in black psyllium might reduce lithium absorption and plasma levels. Some case reports describe a reduction in plasma lithium levels with concomitant administration of blond psyllium. This was reversed when psyllium was stopped. This interaction may also occur with black psyllium.
Metformin (Glucophage)
Theoretically, black psyllium might increase the therapeutic and adverse effects of metformin.
Animal research shows that concurrent consumption of blond psyllium with metformin slows and increases the absorption of metformin. This interaction may also occur with black psyllium. To avoid changes in absorption, take psyllium 30-60 minutes after metformin.
Olanzapine (Zyprexa)
Theoretically, taking black psyllium at the same time as olanzapine might reduce olanzapine absorption.
The fiber in black psyllium might decrease the absorption of olanzapine. A single case report describes a reduction in the effectiveness of olanzapine when it was concomitantly administered with an unspecified type of psyllium 3 grams orally twice daily. This effect was reversed when psyllium was stopped.
Digoxin (Lanoxin)
Theoretically, taking black psyllium at the same time as digoxin might reduce digoxin absorption and decrease digoxin levels.
Psyllium might bind digoxin in the gut. However, some clinical evidence suggests that psyllium does not impact digoxin absorption.
Ethinyl Estradiol
Theoretically, taking black psyllium at the same time as ethinyl estradiol might alter levels of estradiol.
Concurrent use of blond psyllium with ethinyl estradiol results in a slight increase in the extent of ethinyl estradiol absorption and a slower rate of absorption. This is unlikely to be clinically significant.
Oral Drugs
Theoretically, psyllium might increase, decrease, or have no effect on the absorption of oral drugs.
Psyllium seems to have variable effects on drug absorption. To avoid changes in absorption, take psyllium 30-60 minutes after oral medications. Animal research shows that blond psyllium delays and increases the absorption of metformin and ethinyl estradiol. Case reports and animal research suggest that blond psyllium might reduce absorption of lithium, digoxin, olanzapine, and carbamazepine. Finally, some pharmacokinetic studies show that psyllium does not affect the absorption of levothyroxine or warfarin. Although many of these studies evaluated blond psyllium, the fiber content in black psyllium may have similar effects.
Inulin
Antidiabetes Drugs
Theoretically, inulin might increase the risk of hypoglycemia with antidiabetes drugs.
Some clinical research shows that inulin improves glycemic control in patients with diabetes; however, it is unclear if it has hypoglycemic effects.
organic Brown Rice Protein
Ace Inhibitors (Aceis)
In laboratory research, hydrolyzed rice protein inhibits angiotensin-converting enzyme (ACE). In animal research, the inhibition of ACE is correlated with a reduction in systolic blood pressure. So far, this effect has not been shown in humans. Theoretically, concomitant use of rice protein and ACE inhibitors may increase the risk of blood pressure becoming too low. Use with caution. ACE inhibitors include benazepril (Lotensin), captopril (Capoten), enalapril (Vasotec), fosinopril (Monopril), lisinopril (Prinivil, Zestril), moexipril (Univasc), perindopril (Aceon), quinapril (Accupril), ramipril (Altace), and trandolapril (Mavik).
