HelloPharmacist Scorecard of Bone, Flesh & Cartilage 440 mg by Nature's Way

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

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 6 active ingredients.
  • “Bone, Flesh & Cartilage Blend” is a proprietary blend — the label gives one combined amount (880 mg) without saying how much of each component you get.

This product contains six active ingredients: Mullein, Black Walnut, Marshmallow, Slippery Elm, White Oak, and Calendula, combined in a 440 mg capsule. Each is a plant-based extract chosen traditionally to support joint and connective tissue health, though the evidence for most is not yet established.

The capsule itself is plant-derived.

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 on these ingredients is limited. For Mullein, Black Walnut, Marshmallow, Slippery Elm, and Calendula, we don't have enough reliable data to rate whether they work for their intended uses—the facts show insufficient evidence for conditions ranging from respiratory health to wound healing and skin concerns.

White Oak has no effectiveness ratings on file. This doesn't mean they don't work; it means large, well-designed human studies are lacking.

The evidence, ingredient by ingredient Mullein Black Walnut Marshmallow Slippery Elm White Oak Calendula

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 4 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most of these ingredients are generally well tolerated for short-term use, but human safety data are limited for all of them. Mullein, Black Walnut, and Marshmallow should be avoided during pregnancy and breastfeeding due to insufficient safety information.

Slippery Elm requires caution in pregnancy and while breastfeeding because safety data are sparse. White Oak and Calendula also lack adequate safety data for pregnancy and breastfeeding.

Black Walnut may cause stomach upset due to its tannin content, and both Black Walnut and Calendula can trigger allergic reactions in sensitive people, particularly those allergic to tree nuts or ragweed-family plants. Rare cases of skin irritation (dermatitis, contact rash) have been reported with Mullein and Slippery Elm.

Side effects, ingredient by ingredient Mullein Black Walnut Marshmallow Slippery Elm White Oak Calendula

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?
  • 4 of the 6 matched ingredients can interact with medications — Calendula, Mullein, Marshmallow, Slippery Elm.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; lithium.
  • For scale: 2,056 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 you take this product, check with your pharmacist if you take lithium—Marshmallow may raise its levels and risk toxicity. Also double-check any oral medications you take regularly, since both Marshmallow and Slippery Elm may slow how your body absorbs them.

If you're on blood thinners like warfarin, be aware that Mullein and Marshmallow carry a minor blood-thinning effect. And if you take CNS depressants such as sedatives or anti-anxiety drugs, flag this product with your pharmacist, though the risk appears small.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product is best suited for adults with no pregnancy or breastfeeding plans who want to explore traditional herbal support for bone and joint health—though evidence of benefit isn't established in our data. If you take lithium, blood thinners, or any regular oral medications, talk with your pharmacist before starting it.

Anyone with a tree nut or ragweed allergy should be cautious.

Marshmallow3 drug types · 2,040 drugs

Lithium

Theoretically, due to potential diuretic effects, marshmallow might reduce excretion and increase levels of lithium.
Marshmallow is thought to have diuretic properties. To avoid lithium toxicity, the dose of lithium might need to be decreased when used with marshmallow.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, marshmallow flower might have antiplatelet effects.
Animal research suggests that marshmallow flower extract has antiplatelet effects. However, the root and leaf of marshmallow, not the flower, are the plant parts most commonly found in dietary supplements. Theoretically, use of marshmallow flower with anticoagulant/antiplatelet drugs can have additive effects, and might increase the risk for bleeding in some patients.

Likelihood Unlikely Evidence D
Oral Drugs

Theoretically, mucilage in marshmallow might impair absorption of oral drugs.
Marshmallow contains mucilage which can affect oral drug absorption. To avoid changes in absorption, take marshmallow 30-60 minutes after oral medications.

Likelihood Possible Evidence D

Slippery Elm1 drug type · 2,022 drugs

Oral Drugs

Theoretically, slippery elm may slow the absorption and reduce serum levels of oral drugs.
Slippery elm inner bark contains mucilage, which may interfere with the absorption of orally administered drugs.

Likelihood Possible Evidence D

Calendula1 drug type · 248 drugs

Cns Depressants

Theoretically, calendula might have additive effects when used with CNS depressants, although this appears to be unlikely.
Although some animal research has suggested that a saponoside constituent in calendula may have sedative effects, calendula has been used for over 30 years without reports of sedation in humans.

Likelihood Unlikely Evidence D

Mullein1 drug type · 122 drugs

Anticoagulant/Antiplatelet Drugs

Lab tests on extracts from different parts of common and dense-flowered mullein plants show that they do have some blood-thinning effects, as they increase the time it takes for blood to clot. This is likely due to at least one of the known constituents of muellein, triterpenoid saponins. However, the effects appear to be mild and results have been inconsistent. Extracts from different plant parts have been show to have varying anticoagulant strengths, with water-based ones being more potent than alcohol-based extracts.

Bone, Flesh & Cartilage 440 mg by Nature's Way: Common Questions

Does Bone, Flesh & Cartilage 440 mg by Nature's Way interact with any medications?
Yes. Based on its ingredients, Bone, Flesh & Cartilage 440 mg has a known interaction with 2,055 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Bone, Flesh & Cartilage 440 mg contains 6 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 while I'm pregnant or breastfeeding?
The safety data for these herbs during pregnancy and breastfeeding are not strong enough. Mullein, Black Walnut, Marshmallow, and Calendula should be avoided in pregnancy; Slippery Elm and White Oak require caution. For breastfeeding, the picture is similar—safety isn't clear enough. Talk with your doctor or pharmacist for personalized advice if you're planning pregnancy or nursing.
Will this help with joint or bone health?
That's what these herbs are traditionally used for, but we don't have enough reliable evidence to say whether they work for bone, cartilage, or joint conditions. The ingredients are generally well tolerated, but you're not getting proven benefit from the science we hold.
What's the difference between the Mullein in this and Mullein supplements sold on their own?
The facts on file don't compare this blend to standalone Mullein supplements. What I can tell you is that the Mullein in this product carries the same interactions—minor blood-thinning effects if you're on anticoagulants—and the same limited safety data as any other Mullein.
Can I take this with my other supplements or vitamins?
The interaction data we have cover medications, not other supplements. If you're taking multiple supplements or herbal products, it's a good idea to check with your pharmacist about potential overlap or conflicts—especially if you take blood thinners or lithium.
Is there a risk of allergic reaction?
Yes. Black Walnut is a tree nut and can trigger nut allergies. Calendula can cause allergic skin reactions, especially in people sensitive to ragweed or related plants like marigolds and daisies. If you have known allergies to tree nuts or the ragweed family, tell your pharmacist before using this product.
How long can I safely use this?
Human safety data are limited for all the herbs in this blend. They're described as generally well tolerated for short-term use, but long-term safety isn't well studied. Check with your pharmacist about how long is right for you.
