HelloPharmacist Scorecard of PowerOmega by Physician's Strength

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

Partial disclosure
Ingredient Transparency · database check
Partial

Most active ingredients list an amount, but at least one is hidden in a blend or missing.

Why this rating?
  • The label discloses an exact amount for 2 of its 4 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (3,360 mg) without saying how much of each component you get.
  • “Omega-3s” is listed as a grouped ingredient — the label gives one combined amount (2,140 mg) without saying how much of each component you get.
  • “Omega-6s” is listed as a grouped ingredient — the label gives one combined amount (1,480 mg) without saying how much of each component you get.

PowerOmega has 4 active ingredients listed: a proprietary blend, wild rosemary oil, linoleic acid, alpha-linoleic acid, and omega-3 and omega-6 blends. The rosemary oil is the named plant extract in the formula.

Linoleic acid and alpha-linoleic acid are essential fatty acids (omega-6 and omega-3 types, respectively), and the sacha inchi oil is also an omega-rich botanical source. There are no inactive ingredients listed for this liquid formula.

Does it work?

Insufficient evidence
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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: omega-3 and omega-6 fatty acid supplementation.
  • We looked for evidence on: Hypertension, Nonalcoholic fatty liver disease (NAFLD), Cardiovascular health, Cholesterol management, Triglyceride reduction, Inflammatory support.
  • The closest evidence on file: Rosemary is rated "Insufficient Reliable Evidence To Rate" for Nonalcoholic fatty liver disease (NAFLD) (Natural Medicines).
  • Also on file: Rosemary is rated "Insufficient Reliable Evidence To Rate" for Hypertension.

For memory, rosemary is rated Possibly Effective — that's the strongest evidence on file for this product. For age-related cognitive decline, alopecia areata, and nonalcoholic fatty liver disease (NAFLD), the evidence is Insufficient to rate either way.

We don't hold effectiveness data for the other ingredients in this product.

The evidence, ingredient by ingredient Rosemary

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 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.

Rosemary is safe in normal culinary amounts, but concentrated extracts and undiluted essential oils require caution. Food amounts are likely fine during pregnancy, but medicinal or large doses should be avoided because the safety data doesn't support them.

When breastfeeding, food amounts are likely okay, but there isn't enough data on medicinal doses, so skip those. Topically, rosemary can cause allergic reactions, lip and gum swelling, allergic contact dermatitis, and in sensitive people, photosensitivity reactions.

In rare cases, occupational asthma from inhaling rosemary dust has been reported. Undiluted rosemary oil and its camphor component might trigger seizures if taken orally.

Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Rosemary.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 372 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking PowerOmega, check with your pharmacist if you take blood thinners or antiplatelet drugs (Moderate risk of increased bleeding), diabetes medications (Moderate risk of low blood sugar), aspirin or other salicylate-containing pain relievers (Moderate risk of additive effects), or medications your liver breaks down via the CYP1A2 pathway (Minor risk). No interactions are documented for linoleic acid, alpha-linoleic acid, or sacha inchi oil.

The bottom line

Scorecard at a glancePartially disclosed formula with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

PowerOmega is worth considering if you're looking for memory support and you don't take blood thinners, diabetes drugs, or aspirin-type pain relievers. If you're on any prescription medication, check your exact drugs with the tool on this page before you start — the rosemary oil in this formula has several documented interactions.

Talk to your pharmacist about whether it's right for you.

Although rosemary powder decreased blood glucose levels in healthy adults, no change in blood glucose levels was seen in adults with type 2 diabetes, most of whom were taking antidiabetes drugs.

Likelihood Possible Evidence B
Aspirin

Theoretically, rosemary might have additive effects with salicylate-containing drugs such as aspirin.
Rosemary is reported to contain salicylates.

Likelihood Possible Evidence D
Choline Magnesium Trisalicylate (Trilisate)

Theoretically, rosemary might have additive effects with salicylate-containing drugs such as choline magnesium trisalicylate.
Rosemary is reported to contain salicylate.

Likelihood Possible Evidence D
Salsalate (Disalcid)

Theoretically, rosemary might have additive effects with salicylate-containing drugs such as salsalate.
Rosemary is reported to contain salicylate.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, rosemary might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that rosemary induces CYP1A2 enzymes. This effect has not been reported in humans.

PowerOmega by Physician's Strength: Common Questions

Does PowerOmega by Physician's Strength interact with any medications?
Yes. Based on its ingredients, PowerOmega has a known interaction with 372 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
PowerOmega contains 4 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.
Is rosemary safe if I'm pregnant?
Food amounts of rosemary are likely fine, but medicinal or large doses should be avoided during pregnancy because the safety data doesn't support them. Talk to your doctor or pharmacist about what's right for you.
Can this help my memory?
Rosemary is rated Possibly Effective for memory support, so there's some evidence behind it. For other uses like age-related cognitive decline or hair loss, we don't have enough reliable evidence to say either way.
What are linoleic acid and alpha-linoleic acid?
They're essential fatty acids your body needs — linoleic acid is an omega-6 fatty acid and alpha-linoleic acid is an omega-3. Your body can't make them, so you have to get them from food or supplements.
Are there any side effects from rosemary?
In normal food amounts, rosemary is well tolerated. In higher doses or concentrated forms, some people have experienced allergic reactions, lip or gum swelling, skin rashes, or in rare cases, asthma-like symptoms from inhaling dust. Undiluted rosemary oil might cause seizures.
Is this safe to take while breastfeeding?
Food amounts of rosemary are likely fine, but we don't have enough safety data on medicinal doses during breastfeeding, so avoid large or concentrated amounts. Talk to your doctor or pharmacist for personalized advice.
