What is this page for?

First and foremost: checking FloraSil against your medications. The heart of this page is the interaction checker and the full interaction report — how this product’s ingredients may interact with prescription and over-the-counter medicines you may be taking.

Around that, we add a pharmacist’s high-level view of the product as a whole — what’s inside, the evidence for its stated use, how transparent the label is, and what safety data exists — so you can see the full picture in one place. It’s educational information from our licensed clinical databases and the clinical staff at HelloPharmacist — not medical advice — and we don’t sell or endorse products. Our editorial policy

HelloPharmacist Scorecard of FloraSil by Flora

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

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.

FloraSil contains one active ingredient: silica, a form of silicon. This product delivers the mineral your body uses in bone formation and connective tissue support.

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 Silicon's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: hair, skin, and nail health.
  • We looked for evidence on: Aging skin, Androgenic alopecia, nail strength, hair growth, skin elasticity.
  • The closest evidence on file: Silicon is rated "Insufficient Reliable Evidence To Rate" for Aging skin (Natural Medicines).
  • Also on file: Silicon is rated "Insufficient Reliable Evidence To Rate" for Androgenic alopecia.

The evidence suggests silica may be possibly effective for osteoporosis. For hair loss (androgenic alopecia) and gum inflammation around dental implants (peri-implantitis), the evidence is insufficient — we don't have enough reliable data to know whether it works.

The evidence, ingredient by ingredient Silicon

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.

Silica from food and most supplements is generally well tolerated. The safety data we hold does not recommend this supplement during pregnancy or while breastfeeding — talk with your doctor or pharmacist about whether it's right for you in those situations.

High-dose or long-term safety hasn't been well studied, so ongoing use should be discussed with your healthcare provider.

Side effects, ingredient by ingredient Silicon

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented in our data for the silica in FloraSil. Still, check your exact medications with the tool on this page or ask your pharmacist — it takes just a minute.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. No medication interactions are currently documented, and safety information is well characterized.

FloraSil may be worth considering if you're interested in bone health support and your doctor or pharmacist gives you the go-ahead. Avoid it during pregnancy or breastfeeding unless your healthcare provider advises otherwise.

If you take any medications or have occupational exposure to dust, mention this supplement to your pharmacist.

FloraSil by Flora: Common Questions

Does FloraSil by Flora interact with any medications?
We do not currently list a known interaction for the mapped ingredients in FloraSil. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
FloraSil 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.
Is FloraSil safe to take long-term?
Long-term safety at high doses hasn't been well studied, so it's worth discussing ongoing use with your pharmacist or doctor. Silica from food and everyday supplements is generally well tolerated, but your personal health picture matters.
Can I take FloraSil while pregnant or breastfeeding?
The safety data advises against it during pregnancy and breastfeeding. Talk with your doctor or pharmacist about your specific situation — they can give you personalized advice based on your needs.
What does silica do in my body?
Silica is a form of silicon that supports bone formation and connective tissue. FloraSil delivers this mineral in supplement form.
Does FloraSil work for hair loss?
The evidence for silica in hair loss isn't established yet — we don't have enough reliable data to say whether it works. It's one area where more research is needed.
Are there any side effects from taking FloraSil?
Silica in the amounts found in food and water isn't associated with side effects in normal use. Long-term safety at higher doses hasn't been well studied, so that's a good question for your pharmacist if you're planning long-term use.
