The Short Answer
Most grocery store bone broth is just glorified soup stock loaded with fillers. Real bone broth should gel when cold (indicating high collagen) and contain nothing but bones, water, acid (vinegar), and organic vegetables.
The cleanest shelf-stable option is FOND Bone Broth. It is one of the rare brands packaged in glass jars (avoiding plastic leaching) and uses regenerative, verified grass-fed sourcing.
For frozen options, Brodo and Millerās Bio Farm are the gold standards. Millerās is the only brand we found that publicly posts their heavy metal lab results, showing lead levels far below safety limits.
Avoid Pacific Foods, which uses "yeast extract" to mimic the savory taste of long-simmered bones without putting in the time.
Why This Matters
Bone broth is a concentrate. When you simmer bones for 24+ hours to extract collagen and minerals, you are also extracting anything else stored in that animal's bone tissueāincluding heavy metals like lead.
Bones sequester lead. Animals exposed to lead in soil, feed, or water store it in their skeletal system. A 2013 study found that organic chicken broth could contain lead levels higher than tap water. While the alarm was somewhat exaggerated (levels were still often below EPA limits), it proves that sourcing is everything. You cannot make clean broth from dirty animals.
Furthermore, most commercial broth is hot-filled into plastic-lined cartons (Tetra Pak). Pouring boiling liquid into plastic-lined cardboard introduces a risk of microplastic and chemical leaching, especially for a product you drink for health.
What's Actually In Store-Bought Broth
Many brands cut corners to lower costs and speed up production. Here is what to watch out for:
- Yeast Extract ā A common flavor enhancer used to add "savory" notes. It contains free glutamate (similar to MSG) and is a sign the broth wasn't simmered long enough to develop flavor naturally. Yeast Extract Vs Msg
- "Natural Flavors" ā A black box ingredient that can contain dozens of synthetic or highly processed compounds. Clean broth doesn't need "flavor"āit is flavor.
- Concentrates & Powders ā Some brands use "bone broth concentrate" diluted with water rather than brewing fresh broth.
- Sugar/Cane Syrup ā Frequently added to balance acidity or mask poor quality.
What to Look For
Green Flags:
- Jell-O Factor: It should be a solid gel when refrigerated. If it stays liquid, it lacks collagen.
- Regenerative / Pasture-Raised: Animals raised on clean pastures have lower heavy metal loads than factory-farmed animals.
- Glass Packaging: Eliminates the risk of plastic or aluminum leaching.
- Third-Party Testing: Brands that explicitly test for lead and glyphosate.
Red Flags:
- Additives: Yeast extract, natural flavors, spices listed as "spice extracts."
- Prop 65 Warnings: Specifically for lead. While Prop 65 limits are strict, a warning label on a health product is a signal to dig deeper.
- Shelf-Stable without Gel: If it pours like water at room temperature, it's likely watered down.
The Best Options
We evaluated brands based on sourcing transparency, packaging materials, and additive-free ingredient lists.
| Brand | Product | Verdict | Why |
|---|---|---|---|
| FOND | Regenerative Bone Broth | ā | Glass jars, regenerative sourcing, heavy metal testing. |
| Miller's Bio Farm | A2 Beef/Chicken Broth | ā | DTC Only. Publishes actual lab reports (<4ppb lead). |
| Brodo | Frozen Bone Broth | ā | Frozen fresh, high gelatin, excellent sourcing. |
| Kettle & Fire | Classic Beef Bone Broth | ā ļø | Certified Glyphosate-Free, but carton packaging & mass production concerns. |
| Bonafide Provisions | Frozen Bone Broth | ā ļø | Excellent ingredients/gel, but carries Prop 65 Lead Warning. |
| Pacific Foods | Organic Bone Broth | š« | Contains yeast extract and "chicken flavor". |
1. FOND Bone Broth (Best Shelf-Stable)
FOND is the standout for shelf-stable broth. They use regenerative sourcing (verified by Land to Market), which ensures the soil and animals are managed holistically. Crucially, they package in glass jars, completely avoiding the plastic-leaching concerns of Tetra Paks. They also claim to test every batch for heavy metals.
2. Miller's Bio Farm (The "Purest" Pick)
If you are willing to order online, Miller's Bio Farm is unmatched in transparency. They recently addressed the lead concern head-on by publishing their lab results, showing lead levels of <4 ppb (parts per billion)āextremely low. Most brands hide this data; Miller's flaunts it.
3. Kettle & Fire (The Convenient Choice)
Kettle & Fire is the most accessible "decent" option. A major pro is their Glyphosate Residue Free certification from The Detox Project. However, they use carton packaging, and some critics have noted their heavy metal testing claims (testing to "5 ppm") are less sensitive than the "ppb" standards used by stricter labs. It's a safe choice, but not the perfect one.
4. Bonafide Provisions (The "Caution" Pick)
Bonafide makes a real, gelatinous broth that is sold frozen. Sourcing-wise, they are excellent. However, they have received Prop 65 notices for lead in their soups/broths in California. While naturally occurring lead is hard to eliminate entirely, the presence of a warning label makes them a "Caution" compared to Miller's or FOND.
The Bottom Line
1. Go for Glass or Frozen. FOND (glass) and Brodo (frozen) are your safest bets for avoiding packaging toxins.
2. Check the Ingredients. If you see "Yeast Extract," put it back. You are buying expensive flavored water, not bone broth.
3. Sourcing is Safety. The best defense against lead is buying broth made from animals raised on clean, regenerative pastures.
FAQ
Does bone broth contain lead?
Yes, it can. Bones sequester lead from the environment. A 2013 study found lead in organic chicken broth. However, levels in high-quality, pasture-raised broth are typically far below safety limits (often <10 ppb). The risk is manageable if you choose brands that test their products.
Is Kettle & Fire clean?
Mostly. It is Certified Glyphosate Free and made with grass-fed bones. The main downsides are the plastic-lined carton packaging and "natural flavors" in some of their soup varieties. Stick to their "Classic" bone broths for the cleanest ingredient list. Kettle And Fire Review
Why is yeast extract bad in broth?
Yeast extract is a source of processed free glutamates. While not technically "MSG," it functions the same way biologicallyātricking your brain into thinking the food is more savory than it actually is. High-quality broth gets its savory flavor from long simmer times, not additives. Yeast Extract Vs Msg
