A clearer way to read nutritional science
What theresearchshows.
Research on tocotrienols and geranylgeraniol is growing. Some findings are encouraging. Others remain uncertain or inconsistent. Understanding the difference starts with knowing what a study actually tested.
Read past
the headline.
The ingredient. The study design. The result.
Each changes how a finding should be understood.
Cells ≠ people
Absorption ≠ benefit
One study ≠ certainty
Understand the type of evidence
Different studies.
Different questions.
A cell experiment, an absorption study and a clinical trial can all contribute useful information. They answer different questions. Select a study type to see what it can—and cannot—tell you.1
These are different research questions, not a universal quality ranking. Study design, measurement and consistency all matter.
Selected findings, explained
A closer look
at human research.
These examples illustrate how to interpret findings. They are not a complete systematic review, and none tested our finished products. The ingredient and study population matter.
Short-term safety2018
Reassuring findings.
A defined study window.
Researchers found no adverse effect on the liver or kidney measurements assessed in postmenopausal women with low bone mass. The studied annatto extract appeared well tolerated at the tested amounts.
This was a specific population, formulation and duration. The trial did not establish lifelong safety or safety for every person.
Ingredient-supplier funded.
Preliminary safety research2023
Human GG research
is still developing.
The researchers found no significant differences in changes over time between GG and placebo for the blood-count and metabolic-panel measures. No serious adverse events were reported; nonserious events occurred in both groups.
This is limited, short-term evidence. Larger, longer and independently replicated studies are needed to better understand safety.
Ingredient-supplier funded.
Bone-turnover markers2018
A marker can change.
The next question remains.
An annatto delta/gamma trial reported favorable changes in selected markers of bone resorption and oxidative stress. Bone resorption means the breakdown of existing bone tissue.
These were biomarker findings. They did not demonstrate fewer fractures or reversal of osteoporosis.

Blood-lipid meta-analysis2020
The combined picture
can be mixed.
The pooled results did not show significant overall reductions in LDL cholesterol, total cholesterol or triglycerides. An increase in HDL cholesterol was reported, with substantial variation between studies.
The analysis covered studies available through November 2019 and was not restricted to annatto delta/gamma. It cannot promise an individual cholesterol response.

Turn a finding into understanding
Good questions
make better readers.
Before applying a result to yourself, look beyond the headline. A study can be carefully conducted and still have limits on what it tells you.
Explore the NIH reading guide (opens in a new tab)Was the same ingredient studied?
Check the named forms, botanical source, amounts and delivery format. A study of a mixed tocotrienol preparation does not automatically describe a purified annatto delta/gamma formula. GG is a separate compound and needs its own evidence.
Who took part, and what was the comparison?
Look at participant numbers, age, health status and study duration. A randomized, blinded trial with a suitable comparison group can reduce bias, but its results still need to be interpreted in the population studied.
Was it a marker or a meaningful health outcome?
A biomarker is a measurable clue, such as a blood or urine test. Changing that clue does not automatically mean fewer fractures, fewer symptoms or a longer life. Ask whether the outcome you care about was actually measured.
How consistent is the wider evidence?
Consider the size of the effect, uncertainty, study quality and whether other teams found similar results. Funding and conflicts should be disclosed; they are context to examine, rather than a substitute for reading the methods.
A clear boundary
What has not
been established?
The studies discussed here do not establish that tocotrienol or geranylgeraniol supplements can:
- Cure cancer
- Prevent dementia
- Reverse osteoporosis
- Treat muscle loss
- Replace cholesterol medication
- Prevent cardiovascular disease
- Eliminate medication side effects
- Guarantee a longer life
Research involving a disease does not automatically establish that a supplement can prevent or treat it. A single study should never be used to promise a guaranteed result.
Safety and responsible use
Start with the label.
Bring it to the conversation.
Follow your product’s serving directions. A study amount is not a personal recommendation. Show the full ingredient label to your healthcare professional when discussing whether a supplement fits your situation.
Read NIH supplement guidance (opens in a new tab)Speak with a qualified clinician first if you:
- Are pregnant or breastfeeding
- Have a diagnosed medical condition
- Take prescription medication
- Use an anticoagulant or antiplatelet medicine
- Are preparing for surgery
NIH notes that high-dose vitamin E can increase bleeding risk when combined with certain anticoagulant or antiplatelet medicines. This is general vitamin E guidance, not a measured interaction rate for our formulas. GG is not vitamin E and requires separate consideration.89
Our approach
Clear ingredients.
Clear expectations.
DeltaPOWER™ provides annatto-derived delta- and gamma-tocotrienols. GG-POWER™ provides geranylgeraniol. We identify the ingredients clearly and present their research as developing nutritional science—not as proof that our products treat disease.
