HelloPharmacist Scorecard of Hemp Seed Oil by Hamilton Healthcare

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

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 4 of its 4 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Hamilton Healthcare Hemp Seed Oil contains 4 active ingredients: omega-3 fatty acids (specifically DHA), omega-6 fatty acids, omega-9 fatty acids, and hemp oil. These are plant-based fats that your body cannot make on its own — the omega-3 and omega-6 content delivers essential fatty acids your diet normally provides, while hemp oil and its omega-9 contribute additional fatty acid nutrition.

The capsules are filled with purified water, gelatin, and glycerin as inactive ingredients to form and preserve the product.

Does it work?

Moderate 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Omega fatty acid nutrition and heart health.
  • We looked for evidence on: Cardiovascular disease (CVD), Coronary heart disease (CHD), Hyperlipidemia, Hypertension, Atopic dermatitis (eczema), Triglyceride support — and 1 related terms.
  • The strongest evidence on file: Docosahexaenoic Acid (dha) is rated "Possibly Effective" for Hyperlipidemia (Natural Medicines).
  • Also on file: Omega-6 Fatty Acids is rated "Possibly Ineffective" for Cardiovascular disease (CVD), Hyperlipidemia.
  • Also on file: Omega-6 Fatty Acids is rated "Insufficient Reliable Evidence To Rate" for Hypertension.

The evidence for what this product does is mixed and incomplete. DHA (the omega-3 in this product) is possibly effective for high cholesterol and preterm labor prevention, but possibly ineffective for cognitive function and ADHD.

Omega-6 fatty acids show mostly uncertain or possibly ineffective ratings across high cholesterol, heart disease, child development, and multiple sclerosis. Hemp oil itself hasn't been reliably studied — the data we hold shows insufficient evidence for eczema, constipation, and familial high cholesterol.

Talk with your doctor about whether this product is right for what you're hoping it will do.

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

DHA is generally well tolerated at typical supplement doses. The most common side effects are belching, fishy aftertaste, loose stools, and nausea.

Rarely, high-dose fish oil containing DHA has been linked to increased bleeding risk in case reports. Hemp seed oil is generally well tolerated in food amounts and larger supplement doses, though concentrated extracts are less studied.

Rare serious events — anaphylaxis, heart rhythm changes, and allergic reactions including swelling and breathing trouble — have been reported with hemp products, and one case of liver inflammation occurred in a young child given very high doses of hemp extract for seizures. For pregnancy and breastfeeding: DHA is rated likely safe in pregnancy and lactation, but use only under your doctor's guidance and choose a purified, low-mercury source; DHA passes into breast milk and is generally acceptable, but confirm the dose and source with your doctor.

Omega-6 fatty acids are rated likely safe in pregnancy but possibly unsafe in lactation — ask your doctor before taking this product while breastfeeding. Safety data for hemp oil in pregnancy and lactation is not on file.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

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

Why this rating?
  • 2 of the 3 matched ingredients can interact with medications — Docosahexaenoic Acid (dha), Hemp.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 1,019 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 this product, check with your doctor or pharmacist if you take blood thinners (anticoagulants or antiplatelet drugs) — DHA may increase bleeding risk. Also double-check if you're on blood pressure medications, diabetes medications, hormone therapy, or ACE inhibitors, as hemp oil and DHA may have additive effects or interfere with how well your drugs work.

If you take medications metabolized by your liver (like certain cancer drugs, antibiotics, or statins), ask your pharmacist whether this product might affect them.

Hemp Oil6 drug types · 938 drugs

Estrogens

Theoretically, hemp might interfere with hormone therapy due to its estrogenic effects.
In an ovariectomized animal model, a diet containing hemp seed 1%, 2%, or 10% resulted in normalized plasma levels of 17-beta-estradiol. The mechanism of action for this effect is unclear.

Likelihood Possible Evidence D
Ace Inhibitors (Aceis)

Theoretically, consuming hemp seed protein isolate with ACE inhibitors might have additive effects and increase the risk of hypotension.
Hemp seed protein hydrolysate has shown ACE inhibitor-like effects in a hypertensive animal model. However, hempseed oil consumption does not seem to reduce blood pressure in humans. Until more is known, monitor blood pressure and potassium levels.

Likelihood Unlikely Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, hemp seed might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs.
In animal research, hemp seed at 5% of the diet inhibits platelet aggregation in vitro. However, in human research, taking hemp seed oil 2 grams daily for 12 weeks does not inhibit the aggregation of platelets in vitro.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, hemp seed protein may have additive effects with antihypertensive drugs.
In a hypertensive animal model, hemp seed protein hydrolysate reduced systolic blood pressure by a mechanism possibly involving the inhibition of renin and angiotensin converting enzyme (ACE) activities. However, there was no effect of hemp seed protein on blood pressure in normotensive animals. Furthermore, hempseed oil consumption does not seem to reduce blood pressure in humans.

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

Theoretically, hemp might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that hemp induces CYP1A2 enzymes.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, hemp might decrease the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that hemp induces CYP3A4 enzymes.

Likelihood Possible Evidence D

Omega-3 Fatty Acids3 drug types · 375 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, DHA may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Although some clinical evidence suggests that DHA might reduce collagen-stimulated platelet aggregation and thromboxane release, most clinical evidence suggests that DHA alone does not affect blood clotting. However, theoretically, when given in combination with EPA as fish oil, concomitant use with anticoagulant or antiplatelet drugs (including aspirin) might increase risk of bleeding.

Likelihood Unlikely Evidence B
Antidiabetes Drugs

Theoretically, taking DHA with antidiabetes drugs might reduce the effects of these medications.
In people with type 2 diabetes, including those taking oral hypoglycemic medications, DHA seems to increase fasting blood glucose levels.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, taking DHA with antihypertensive drugs might increase the risk of hypotension.
Fish oils containing DHA can lower blood pressure and might have additive effects in patients treated with antihypertensives; use with caution.

Hemp Seed Oil by Hamilton Healthcare: Common Questions

Does Hemp Seed Oil by Hamilton Healthcare interact with any medications?
Yes. Based on its ingredients, Hemp Seed Oil has a known interaction with 1,018 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Hemp Seed Oil 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.
Does this product have any side effects?
The most common ones are belching, a fishy aftertaste, loose stools, and nausea — especially with DHA. Rarely, serious allergic reactions (hives, swelling, breathing trouble) or heart rhythm problems have been reported with hemp products. Stop and get help if you have any signs of an allergic reaction or feel your heartbeat change.
Is it safe to take while pregnant or breastfeeding?
DHA is rated likely safe in both pregnancy and lactation, but use only under your doctor's guidance and pick a purified source low in mercury. Omega-6 is likely safe in pregnancy but possibly unsafe while breastfeeding — talk with your doctor before taking this product if you're nursing. Safety data for hemp oil in pregnancy and lactation isn't on file, so ask your doctor about that ingredient too.
Can this help my cholesterol or brain function?
DHA in this product is possibly effective for high cholesterol, but the evidence for brain function and ADHD is weak — it's rated possibly ineffective for those. Hemp oil and omega-6 haven't been reliably studied for these uses. Ask your doctor if this is the right supplement for your health goal.
What's the difference between hemp oil and cannabis?
Hemp oil is made from hemp seeds and contains fatty acids and other compounds, but not the psychoactive ingredient THC that cannabis has. Hemp seed oil won't get you high and is sold as a food supplement.
Why does the product warning mention liver enzymes and drug interactions?
Hemp can speed up how your liver breaks down certain medications, potentially making them less effective. DHA can also thin your blood and lower blood pressure. If you're on prescription drugs, checking with your pharmacist before you start this product helps make sure nothing conflicts.
Is it okay to take this with fish oil?
Both contain omega-3 fatty acids and carry the same interactions with blood thinners and blood pressure drugs. Taking both together could increase those risks, so ask your doctor or pharmacist before combining them.
