HelloPharmacist Scorecard of Fast Relief PMS by Success Chemistry

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Fast Relief PMS has one active ingredient: krill oil. Krill oil is a source of omega-3 fatty acids and other compounds derived from tiny shrimp-like crustaceans.

The capsules also contain gelatin, glycerin, and water as inactive ingredients to hold and deliver the krill oil.

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 Krill Oil's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Hormone balance and PMS symptom support.
  • We looked for evidence on: Premenstrual syndrome (PMS), Dysmenorrhea, Hormonal balance, Menstrual cycle support.
  • The closest evidence on file: Krill Oil is rated "Insufficient Reliable Evidence To Rate" for Premenstrual syndrome (PMS) (Natural Medicines).
  • Also on file: Krill Oil is rated "Insufficient Reliable Evidence To Rate" for Dysmenorrhea.

The evidence for krill oil in PMS specifically isn't listed in the data we hold. What we do have is krill oil's rating for other uses: it's possibly effective for dry eye, but for aging skin, Alzheimer disease, cancer, high cholesterol (hyperlipidemia), and cognitive function, there isn't enough reliable evidence to rate it either way.

If you're taking this for PMS, talk with your pharmacist about whether the research supports that use.

The evidence, ingredient by ingredient Krill Oil

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.

Krill oil is generally well tolerated when taken at doses up to 4 grams daily. The most common side effects are mild and involve your stomach and digestion: bloating, decreased appetite, diarrhea, fishy burps, flatulence, heartburn, nausea, and stomach discomfort.

These tend to be less severe with krill oil than with fish oil. Headache, tiredness, and dizziness have been reported rarely.

Avoid krill oil if you have a shellfish allergy, and use caution if you have a bleeding disorder. There isn't enough safety data to know whether it's safe in pregnancy or while breastfeeding — talk with your doctor before using it in either situation.

Side effects, ingredient by ingredient Krill Oil

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?
  • 1 of the 1 matched ingredient can interact with medications — Krill Oil.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 208 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 you take Fast Relief PMS, double-check with your pharmacist if you're on a blood thinner like warfarin or aspirin, or any diabetes medication like metformin or insulin. Krill oil can theoretically increase bleeding risk with anticoagulants and antiplatelet drugs, and may lower blood sugar with diabetes drugs.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Krill oil is a reasonable choice if you're looking for omega-3 support and can tolerate fish-based supplements. But if you take a blood thinner, diabetes medication, or have a bleeding disorder, check with your pharmacist first.

And if you're pregnant, breastfeeding, or have a shellfish allergy, discuss this with your doctor before starting.

Krill Oil2 drug types · 208 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, krill oil may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Taking high doses of omega-3 fatty acids from fish oil can modestly decrease platelet aggregation. Since krill oil also contains these fatty acids, taking high doses of krill oil might also inhibit platelet aggregation. Theoretically, taking high doses of krill oil with antiplatelet or anticoagulant drugs might increase the risk of bleeding. However, the omega-3 content of krill oil is much lower than that of fish oil.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, taking krill oil with antidiabetes drugs might increase the risk of hypoglycemia.
Some research in animals and humans shows that krill oil might lower blood glucose levels. However, a small study shows that taking krill oil does not reduce blood glucose levels in patients with type 2 diabetes, most of whom were taking antidiabetes drugs.

Fast Relief PMS by Success Chemistry: Common Questions

Does Fast Relief PMS by Success Chemistry interact with any medications?
Yes. Based on its ingredients, Fast Relief PMS has a known interaction with 208 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Fast Relief PMS contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
Will this give me the fish-oil burps everyone talks about?
Possibly, but probably less than fish oil would. Fishy burps are one of the most common side effects, but they seem to happen less often and less intensely with krill oil compared to regular fish oil. If they do happen, they're usually mild.
Can I take this if I'm allergic to shellfish?
No — you should avoid krill oil. Krill are tiny crustaceans, so if you have a shellfish allergy, krill oil could trigger a reaction. Talk with your doctor about other options.
Is it safe to take while I'm pregnant?
There isn't enough reliable safety data to know either way. Talk with your doctor before using krill oil during pregnancy so you can make a decision that's right for your situation.
What is krill oil actually for?
Based on the evidence we have, krill oil is possibly effective for dry eye. For other uses like aging skin, Alzheimer disease, cancer, high cholesterol, and brain function, there isn't enough reliable evidence yet to say whether it works.
Can I take this with my blood thinner?
You need to check with your pharmacist first. Krill oil's omega-3 fatty acids may increase bleeding risk when combined with blood thinners like warfarin or aspirin — it's a moderate interaction you'll want to discuss before starting.
