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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Formula 835 has 2 active ingredients, both forms of saw palmetto extract — Saw Palmetto extract and Saw Palmetto P.E. (a concentrated plant extract). The product also contains inactive ingredients: vegetable cellulose, gelatin, silica, and vegetable magnesium stearate, which serve as the capsule and binding materials.

Does it work?

Leans against
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
Leans against

The strongest graded evidence we hold for the stated purpose leans against a benefit.

Why this rating?
  • The label markets this product for: prostate health and urinary function.
  • We looked for evidence on: Benign prostatic hyperplasia (BPH), Non-neurogenic lower urinary tract symptoms (LUTS), Prostatitis, Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS), urinary symptoms, prostate support.
  • The closest evidence on file: Saw Palmetto is rated "Possibly Ineffective" for Benign prostatic hyperplasia (BPH) (Natural Medicines).
  • Also on file: Saw Palmetto is rated "Insufficient Reliable Evidence To Rate" for Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS), Prostatitis, Non-neurogenic lower urinary tract symptoms (LUTS).

The evidence for saw palmetto is mixed. It's rated possibly effective for one specific urological procedure (transurethral resection of the prostate), but possibly ineffective for benign prostatic hyperplasia—the most common reason people use it.

For hair loss, chronic bronchitis, and lower urinary tract symptoms, we don't have enough reliable evidence to say whether it works. Talk with your doctor about whether this product fits your actual goal.

The evidence, ingredient by ingredient Saw Palmetto

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.

Saw palmetto is generally well tolerated, and most side effects are mild and reversible. The most common ones are abdominal pain, constipation, diarrhea, dizziness, headache, nausea, and fatigue.

Rarely, it's been linked to heart rhythm changes, skin reactions, and changes in blood pressure—if you develop chest pain, severe dizziness, or unusual bruising, stop and contact your doctor. Do not use this product if you're pregnant or breastfeeding.

The safety data advises against it because of possible hormone effects and insufficient information about safety during nursing. If you're considering this while pregnant or nursing, talk with your doctor or pharmacist about your options.

Side effects, ingredient by ingredient Saw Palmetto

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 — Saw Palmetto.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 174 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 or antiplatelet drugs (like warfarin, aspirin, or clopidogrel)—saw palmetto may increase bleeding risk. Also double-check if you're on hormonal birth control or estrogen therapy, as saw palmetto might reduce their effectiveness.

Formula 835 by DC: Common Questions

Does Formula 835 by DC interact with any medications?
Yes. Based on its ingredients, Formula 835 has a known interaction with 174 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Formula 835 contains 2 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 Formula 835 if I'm on birth control?
Not without checking first. Saw palmetto may have antiestrogenic effects and could theoretically reduce how well your contraceptive works. Talk with your doctor or pharmacist before adding this product to your routine.
What are the most common side effects?
Saw palmetto is generally well tolerated. The most common mild side effects are abdominal pain, constipation, diarrhea, dizziness, headache, nausea, and fatigue. These are typically infrequent and reversible.
Is Formula 835 safe during pregnancy?
No. The safety data advises against use during pregnancy because of possible effects on hormones and lack of safety information. If you're pregnant or planning to become pregnant, talk with your doctor before taking this product.
Will this help with hair loss?
There isn't enough reliable evidence to say whether saw palmetto works for hair loss. If that's your reason for considering it, ask your doctor about options with clearer evidence.
Can I take this while breastfeeding?
No. There isn't enough safety information about saw palmetto during breastfeeding, so it's best to avoid it. Talk with your doctor or pharmacist about safer alternatives if you need one.
What's the difference between the two saw palmetto ingredients?
Both are forms of saw palmetto extract—one is a standard extract and one is a concentrated plant extract (P.E.). They have the same interactions and safety profile; the product just includes both forms.
