HelloPharmacist Scorecard of Recancostat Powder Unflavored by Integrative Therapeutics

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 Sep 10, 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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Recancostat Powder contains three active ingredients: L-cysteine, L-glutathione, and AnthoRedoxin. L-cysteine is an amino acid that supports your body's antioxidant systems.

L-glutathione is another amino acid compound that plays a role in cellular defense. The product also contains silicon dioxide as an inactive ingredient (a common flow agent in powders).

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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Cisplatin-induced neurotoxicity — rated "Possibly Effective" (Glutathione) (Natural Medicines).

The evidence we hold doesn't establish that L-cysteine works for hair loss, leg ulcers, hangovers, stroke, or gastritis — the ratings are insufficient. L-glutathione shows possibly effective evidence for one use: reducing nerve damage (neurotoxicity) from the cancer drug cisplatin.

For other uses listed — fatty liver disease, Alzheimer's disease, athletic performance, and cataracts — the evidence is insufficient to rate it. The effectiveness data on AnthoRedoxin isn't on file.

The evidence, ingredient by ingredient L-cysteine Glutathione

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 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.

L-cysteine is generally well tolerated at food amounts, but the safety of high-dose supplements over time isn't well studied, so caution is advised at supplement doses. L-glutathione appears generally well tolerated short-term by mouth, but long-term safety data is limited.

If inhaled as a mist, glutathione can cause airway narrowing and shortness of breath in people with asthma. During pregnancy, L-glutathione safety data is insufficient — avoid it unless your doctor advises otherwise.

During breastfeeding, the same caution and avoidance apply. L-cysteine is rated likely safe in pregnancy.

We hold no pregnancy or breastfeeding data for AnthoRedoxin.

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 2 matched ingredients can interact with medications — L-cysteine.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 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 Recancostat, double-check with your doctor or pharmacist if you take antidiabetes drugs (blood sugar medications) — L-cysteine may increase the risk of low blood sugar. No other medication interactions are documented for the ingredients we could check, but we hold no interaction data for AnthoRedoxin.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Recancostat may be worth considering if you're exploring support for cisplatin-related nerve damage under your doctor's care, though evidence for most other uses is thin. If you take any diabetes medication, check with your doctor or pharmacist before starting, because L-cysteine might lower your blood sugar.

Pregnant or breastfeeding people should talk with their doctor first, especially about L-glutathione. Your own healthcare provider is the right person to confirm whether this product fits your situation.

Recancostat Powder Unflavored by Integrative Therapeutics: Common Questions

Does Recancostat Powder Unflavored by Integrative Therapeutics interact with any medications?
Yes. Based on its ingredients, Recancostat Powder Unflavored has a known interaction with 86 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Recancostat Powder Unflavored contains 3 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 L-cysteine really help with hair loss?
The evidence we have isn't strong enough to rate it. We'd need more reliable studies to know whether it works for androgenic alopecia (the most common type of hair loss).
Is this safe to take long-term?
L-cysteine at food amounts is fine, but long-term safety of supplement-level doses hasn't been well studied, so caution is advised. L-glutathione appears okay short-term by mouth, but long-term data is limited. Talk to your doctor if you're planning to use it regularly.
Can I take this while I'm pregnant?
L-cysteine is rated likely safe in pregnancy. L-glutathione doesn't have enough safety data — avoid it unless your doctor says it's okay. We don't have pregnancy data for AnthoRedoxin. Your doctor or pharmacist can help you decide what's right for you.
Can I take this while breastfeeding?
L-glutathione doesn't have enough safety information during breastfeeding, so caution and avoidance are advised unless your doctor advises otherwise. We don't have breastfeeding data on file for L-cysteine or AnthoRedoxin — check with your doctor or pharmacist.
What is L-glutathione actually for?
In our data, L-glutathione shows possibly effective evidence for reducing nerve damage from the cancer drug cisplatin. For other uses like fatty liver disease or Alzheimer's, the evidence isn't established yet.
