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

The interaction bottom line No known interaction

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 30, 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 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 naturally occurring mineral form of silicon. It's meant to support bone health and connective tissue.

The capsule also holds several inactive ingredients — microcrystalline cellulose, hydroxypropyl methylcellulose, corn syrup solids, and magnesium stearate — which are fillers and binders that hold the capsule together.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: support healthy hair, skin, and nails.
  • We looked for evidence on: hair loss, nail brittleness, skin elasticity.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

Silica is possibly effective for osteoporosis, according to the evidence we have on file. For hair loss (androgenic alopecia) and dental health around implants, the evidence isn't reliable enough yet to rate whether it works.

If bone health is your goal, that's where the research points most clearly.

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 typical supplement doses is generally well tolerated, though long-term and high-dose safety hasn't been thoroughly studied. The product's safety data advises against use during pregnancy and while breastfeeding, so if you're pregnant, planning to become pregnant, or nursing, talk with your doctor or pharmacist before taking it.

The serious adverse effects listed in the literature refer to inhaled crystalline silicon dust in occupational settings — a risk that doesn't apply to swallowing a capsule.

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 for the ingredients we could check in FloraSil. That said, absence of documented interactions isn't a guarantee none exist, so run your current medications through the interaction checker on this page before starting.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and safety information is well characterized.

FloraSil may be worth considering if you're looking to support bone health, since silica shows possible benefit for osteoporosis. Avoid it if you're pregnant or breastfeeding.

If you take medications regularly, check them against the tool on this page, and talk with your doctor or pharmacist about whether this supplement fits your health plan.

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.
Does FloraSil actually help with osteoporosis?
Silica is rated possibly effective for osteoporosis based on the data we have. That means there's some research backing it, but the evidence isn't rock-solid yet. Talk with your doctor about whether it makes sense for your bone health plan.
Will this help my hair grow?
The evidence for silica and hair loss isn't reliable enough to rate. We don't have solid data showing it works, so we can't say one way or the other.
Is silica safe to take every day?
Silica from food and supplements in normal amounts is generally well tolerated. What we don't know is whether taking high doses or using it long-term is safe — that hasn't been studied well. If you're planning to take it regularly, check with your doctor or pharmacist.
Can I take this while pregnant?
No — the safety data advises against use during pregnancy. If you're pregnant or planning to become pregnant, talk with your doctor or pharmacist before taking FloraSil.
Is this safe while breastfeeding?
The safety data advises against use while breastfeeding. If you're nursing, check with your doctor or pharmacist before starting this supplement.
What are the inactive ingredients?
The capsule contains microcrystalline cellulose, hydroxypropyl methylcellulose, corn syrup solids, and magnesium stearate — common fillers and binders used to make the capsule work.
