HelloPharmacist Scorecard of CA-Clear by Future Body Sciences

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

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 4 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (2 mL) without saying how much of each component you get.

CA-Clear is a liquid supplement with four active ingredients. Soursop (also called graviola) is a tropical fruit extract; European mistletoe is an herb extract; Venus' Fly Trap and Sutherlandia are plant extracts.

The product also contains purified water and ethanol as inactive ingredients.

Does it work?

Couldn't assess
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 assessable

The label doesn't state a purpose we can grade — see each ingredient's own graded uses on its monograph instead.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for what soursop, European mistletoe, Venus' Fly Trap, and Sutherlandia actually do is not established in our data. Soursop has been studied for HPV, headache, and use as an insect repellent, but the evidence wasn't reliable enough to rate it.

European mistletoe showed mostly ineffective or insufficient evidence for melanoma, head and neck cancer, breast cancer, gastric cancer, and chemotherapy-related diarrhea. We don't have effectiveness ratings on file for Venus' Fly Trap or Sutherlandia.

The evidence, ingredient by ingredient Graviola European Mistletoe

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.

Soursop raises several safety flags. Regular use may cause stomach pain and nausea, and rare but serious side effects include movement disorders and nerve damage (myeloneuropathy) that resemble Parkinson's disease — even low amounts of soursop fruit or tea may worsen symptoms in people with Parkinson's.

The safety data advises against soursop during pregnancy and breastfeeding. European mistletoe in raw form is toxic if swallowed; only standardized products under medical supervision should be used.

It's generally well tolerated in small amounts but not thoroughly studied. At high doses it may cause diarrhea, cramps, vomiting, chills, fever, headache, nausea, or rash.

The safety data advises against European mistletoe during pregnancy and breastfeeding. We have no safety data on file for Venus' Fly Trap or Sutherlandia.

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

Why this rating?

  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs.
  • For scale: 294 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.

Does CA-Clear by Future Body Sciences interact with any medications?
Yes. Based on its ingredients, CA-Clear has a known interaction with 294 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
CA-Clear 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.
Can I take this if I'm pregnant or breastfeeding?

Does soursop actually treat HPV or headaches?
The evidence isn't solid enough to say. Studies on soursop for HPV and headache haven't produced reliable results in our data, so we can't rate whether it works.
What does European mistletoe do in this formula?
European mistletoe has been studied for cancer and cancer-related side effects, but the evidence shows it's mostly ineffective or insufficient to rate for melanoma, head and neck cancer, breast cancer, and chemotherapy-related diarrhea.
Is there anything in this product I should know about?
Yes — soursop has a serious concern: even low amounts may worsen symptoms of Parkinson's disease. If you or a family member has Parkinson's, avoid this product. Also, raw European mistletoe is toxic; only standardized extracts should be used, and only under medical guidance.
