HelloPharmacist Scorecard of Gamma-O by Gamma 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.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Gamma-O contains three active ingredients: gamma oryzanol (a plant compound), polyunsaturated fat, and monounsaturated fat. It's a liquid formula with inactive ingredients including corn oil, fructose, and other excipients.

Gamma oryzanol is the ingredient with established research behind it; the fats support its delivery.

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Gamma-oryzanol's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: builds muscle and increases testosterone naturally.
  • We looked for evidence on: Athletic performance, Muscle strength, testosterone enhancement, body composition, lean mass.
  • The closest evidence on file: Gamma-oryzanol is rated "Insufficient Reliable Evidence To Rate" for Athletic performance (Natural Medicines).
  • Also on file: Gamma-oryzanol is rated "Insufficient Reliable Evidence To Rate" for Muscle strength.

Gamma oryzanol in Gamma-O is possibly effective for dyslipidemia (abnormal cholesterol and triglyceride levels). For athletic performance and atopic dermatitis (eczema), we have insufficient evidence to rate how well it works.

The data we hold doesn't establish effectiveness for other uses.

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Gamma oryzanol is generally well tolerated in studies, though long-term safety hasn't been thoroughly established. The safety data advises against using Gamma-O during pregnancy because there isn't enough information to know it's safe.

The same applies to breastfeeding — avoid it while nursing. If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before starting.

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for the ingredients we could check. That said, we weren't able to verify the fat components — talk with your doctor or pharmacist about whether Gamma-O fits with your current medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. No medication interactions are currently documented, and some safety-information gaps remain.

Gamma-O may be worth considering if you're looking to support cholesterol levels, since gamma oryzanol shows some promise there. If you're pregnant, breastfeeding, or taking any medications, clear it with your doctor or pharmacist first.

Because we couldn't fully check the fat ingredients, mention this product to your healthcare provider so they can review it in the context of your complete health picture.

General Statements

BUILDS MUSCLE/BURNS FAT

Gamma-O has been demonstrated to naturally increase testosterone levels and enhance the release of endorphins that lower stress. Used as part of a sound training program, the increase in testosterone and endorphins aids in the development of lean muscle tissue while burning off excess fat without the harmful side effects of steroids or andro products. Additionally, Gamma-O acts to interfere with the absorption of cholesterol into the body, helping to naturally maintain cholesterol levels already within the normal range. Gamma-O also possesses strong antioxidant properities which can protect heart vessels from free-radical damage. Gamma Oryzanol is a rice bran extract, made from plant sterols and ferulic acid. Our proprietary process of turning the powder extract into a liquid emulsion enhances absorption. This is the most powerful form of Gamma Oryzanol that can be absorbed by the human body. Professional Athletes on Gamma-O experienced increased strength, reduced excess body fat, enhanced energy during workouts and reduced post-workout soreness.

Gamma-O by Gamma Labs: Common Questions

Does Gamma-O by Gamma Labs interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Gamma-O. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Gamma-O contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Does gamma oryzanol actually work for cholesterol?
The evidence shows it's possibly effective for dyslipidemia — that's abnormal cholesterol and triglyceride levels. It's not a slam-dunk, but the research is encouraging enough to make it worth a conversation with your doctor if cholesterol is a concern.
Can I take this while pregnant?
No — the safety data advises against it during pregnancy because there isn't enough information to know it's safe. Talk with your doctor or pharmacist before using it if you're pregnant or planning to become pregnant.
What about breastfeeding?
The data says to avoid Gamma-O while breastfeeding due to lack of reliable safety information. Check with your doctor or pharmacist if you're nursing and interested in this product.
Will this interact with my blood pressure or cholesterol medications?
No interactions are documented for gamma oryzanol, which is the main active ingredient we could fully check. The fat components we couldn't evaluate — run your specific medications through the search tool on this page and confirm with your pharmacist to be sure.
Is this liquid form better than a capsule?
The product facts we hold don't compare forms, so I can't tell you that. The liquid form makes it easy to adjust your dose, but whether it's 'better' depends on your preference and how your body responds.
What are the inactive ingredients?
Gamma-O contains corn oil, fructose, polysorbate-80, potassium sorbate, sodium carboxymethylcellulose, and purified water. If you're sensitive to any of these, mention it to your pharmacist.
