HelloPharmacist Scorecard of FemCycle by Dr. Garber's

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 30, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 5 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (83 mg) without saying how much of each component you get.

FemCycle is a liquid supplement with 5 active ingredients: Common Juniper, Black Currant, Raspberry, Glauconite, and Ovarian extract. It also contains glycerin, purified water, and alcohol as inactive ingredients (excipients that help deliver and preserve the formula).

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.

Why this rating?
  • The label markets this product for: female cycle balance.
  • We looked for evidence on: Dysmenorrhea, Premenstrual syndrome (PMS), Menopausal symptoms, menstrual irregularity, hormonal balance.
  • The closest evidence on file: Black Currant is rated "Insufficient Reliable Evidence To Rate" for Menopausal symptoms (Natural Medicines).
  • Also on file: Black Currant is rated "Insufficient Reliable Evidence To Rate" for Premenstrual syndrome (PMS), Dysmenorrhea.

The evidence we hold does not establish effectiveness for any of the conditions associated with these ingredients. Common Juniper is listed for gastroesophageal reflux disease (GERD), rheumatoid arthritis, urinary tract infections, wound healing, kidney stones, and bronchitis — all rated insufficient evidence.

Black Currant has insufficient evidence for Alzheimer disease, liver disease, common cold, cough, and atopic dermatitis (eczema). We have no effectiveness data for Raspberry, Glauconite, or Ovarian extract.

The evidence, ingredient by ingredient Juniper Black Currant

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Common Juniper is generally well tolerated in food amounts at low doses used short-term, but medicinal doses may irritate the kidneys and shouldn't be used long-term. It is unsafe in pregnancy because it may affect the uterus; do not use if you're pregnant.

It's best avoided while breastfeeding due to insufficient safety information. Black Currant berry is safe as food, but concentrated supplements are less studied — check with your doctor before using a supplement form.

Adverse effects are uncommon; in one trial of 2,154 people taking black currant seed oil, a small number reported mild diarrhea within 2–10 days of starting. Topical juniper can cause skin irritation, allergies, and rarely severe reactions with sun exposure; respiratory allergies from repeated juniper pollen exposure have also been reported, though this product is ingested.

Side effects, ingredient by ingredient Juniper Black Currant

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 2 matched ingredients can interact with medications — Juniper, Black Currant.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 302 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 FemCycle, check with your pharmacist or doctor if you take antidiabetes drugs (risk of low blood sugar), blood thinners or antiplatelet drugs like warfarin or aspirin (increased bleeding risk), antipsychotics (phenothiazines), diuretics (water pills), or lithium. No interactions are documented for Raspberry, Glauconite, or Ovarian extract in our data.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

If you take diabetes medications, blood thinners, antipsychotics, diuretics, or lithium, you'll want to talk with your doctor or pharmacist before starting FemCycle — the interactions could affect how those drugs work or raise your risk of side effects. Pregnant people should not use this product.

Because effectiveness for the conditions linked to these ingredients hasn't been established, weigh that against the interaction risks with your own healthcare provider.

Black Currant2 drug types · 140 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, black currant seed oil might increase the risk of bleeding if used in combination with anticoagulant or antiplatelet drugs.
Gamma-linolenic acid (GLA), a constituent of black currant seed oil, appears to have antiplatelet effects.

Likelihood Possible Evidence D
Phenothiazines

Theoretically, black currant seed oil might increase the risk of seizure in patients receiving phenothiazines.
Black currant seed oil contains gamma-linolenic acid (GLA). There is some concern that taking supplements containing GLA might cause seizures, or lower the seizure threshold, when taken with phenothiazines, although there is no evidence that black currant seed oil causes seizures. In one report, three patients with schizophrenia who had received phenothiazines developed EEG changes suggestive of temporal lobe epilepsy after starting treatment with GLA, although none experienced an actual seizure. In another report, two patients with schizophrenia who were stabilized on phenothiazines developed seizures when evening primrose 4 grams daily, which contains GLA, was added. One of these patients had a prior history of seizures.

What's Common Juniper in this supplement for?
The product lists Common Juniper for conditions like GERD, rheumatoid arthritis, urinary tract infections, and others — but the evidence to support those uses isn't established in our data.
