You’ve seen the boxes. They’re everywhere. Neatly stacked rows of "all-natural" and "artisan" broths promising gut health and glowing skin. But here’s the thing—most of them are basically salty water with a hint of vegetable scraps. If you’re looking for low salt bone broth because you’re managing blood pressure or just tired of feeling like a bloated balloon, you’ve probably realized that "low sodium" on a label often means "zero flavor."
It’s frustrating.
Truly great bone broth shouldn't need a mountain of salt to taste good. It should be thick. It should jiggle like Jell-O when it’s cold—that’s the gelatin, the good stuff. When companies mass-produce this stuff, they skip the 24-hour simmer. They use high-heat extraction that kills the nuances. Then, they dump in sodium to mask the fact that the liquid is thin and lifeless.
The sodium trap in your "healthy" soup
Most people don't realize that a standard cup of beef broth can pack 800mg of sodium. That’s more than a third of what the American Heart Association says you should have in a whole day. For someone on a DASH diet or managing kidney issues, one bowl of soup can be a medical disaster.
But why is it so high? Salt is a preservative. It’s cheap. It hides the taste of over-processed bones.
When you switch to a low salt bone broth, you’re actually tasting the ingredients. You’re tasting the marrow, the roasted mirepoix, and the slow-leached minerals. If a broth tastes "thin" without salt, it wasn't made right. A real reduction—a fond de veau style—has a natural sweetness and a sticky mouthfeel that satisfies the palate without needing a salt lick's worth of seasoning.
What science actually says about those minerals
Let's talk about the "mineral powerhouse" claim. You’ll hear influencers say bone broth is a "calcium goldmine." Honestly? That’s mostly a myth.
A study published in Food & Nutrition Research analyzed the nutrient content of various bone broths and found that calcium and magnesium levels were actually quite low. We’re talking less than 5% of your daily value per serving. If you’re drinking it just for the minerals, you’re better off eating a stalk of broccoli.
The real value is the amino acids.
Glycine and proline. These are the stars of the show. Glycine isn't just a "building block" for collagen; it’s a neurotransmitter. It helps with sleep. It helps your liver detoxify. When you opt for a low salt bone broth, you’re getting these benefits without the inflammatory spike that high sodium causes in sensitive individuals.
The lead controversy (and why it’s overblown)
A few years back, a study in Medical Hypotheses suggested that bone broth might be high in lead because bones sequester heavy metals. People panicked. However, subsequent testing by labs like ConsumerLab found that while trace amounts exist (as they do in almost all soil-grown foods), the levels in a typical serving are lower than what you’d find in many tap waters. If you’re worried, stick to organic bones from grass-fed cattle. These animals aren't munching on pesticide-laden grain that concentrates heavy metals in their skeletal system.
How to spot a fake low sodium label
Marketing is sneaky. You have to be a detective.
- Reduced Sodium: This just means it has 25% less salt than their original version. If the original was a salt bomb, the "reduced" version is still a grenade.
- Low Sodium: This is a regulated term. It must contain 140mg or less per serving.
- No Salt Added: This is the holy grail for DIY control. It means exactly what it says, though some sodium occurs naturally in the celery and meat.
Check the ingredients for "yeast extract" or "hydrolyzed vegetable protein." Those are just fancy ways of saying MSG-adjacent flavor enhancers. They add a savory kick without technically ticking the "salt" box on the nutrition label, but they can still trigger headaches or bloating in some folks.
Making it at home (without the blandness)
If you want the best low salt bone broth, you have to make it. Period. It’s cheap. It’s easy. It just takes time.

Go to a local butcher. Ask for "knuckle bones" and "pipe bones." You want joints because joints have cartilage. Cartilage becomes gelatin.
- Roast them. Don't skip this. Roast the bones at 400 degrees until they are dark brown. No brown, no flavor.
- The Acid Factor. Add a splash of apple cider vinegar. Does it pull out more calcium? Maybe a tiny bit. But mostly, it helps break down the connective tissue so the broth sets up firm.
- The Aromatics. Since you aren't using salt, you need "umami" from other places. Throw in dried shiitake mushrooms, scorched onions, and a couple of star anise pods. The star anise won't make it taste like licorice; it just makes the beef taste "beefier."
- The Long Simmer. 12 hours for chicken. 24 to 48 for beef. Use a slow cooker or a heavy Le Creuset.
Why your gut actually cares
The "leaky gut" conversation is everywhere. While the term isn't always used by clinical gastroenterologists, they do talk about "intestinal permeability."
The gelatin in low salt bone broth acts like a soothing balm. It helps hold water in the intestines, which keeps things moving. More importantly, the amino acid glutamine helps maintain the integrity of the intestinal wall. When you’re dealing with IBS or Crohn’s, salt can be an irritant. High-sodium diets have been linked to changes in the gut microbiome that favor pro-inflammatory bacteria. By choosing the low-salt route, you’re giving your gut the building blocks it needs without the chemical stress.
Real talk: The taste transition
If you’re used to the Standard American Diet, your first sip of unsalted broth will taste like... hot dishwater.
I’m being serious. Your taste buds are scorched.
It takes about two weeks for your salt receptors to reset. In the meantime, don't just suffer. Add a squeeze of fresh lemon juice or a dash of high-quality balsamic vinegar. The acid "brightens" the flavor in the same way salt does, tricking your brain into thinking the dish is more seasoned than it actually is. Fresh herbs like parsley or cilantro added at the very end also provide a hit of potassium, which actually helps flush out excess sodium from your system.

Buying Guide: The brands that aren't lying
If you absolutely cannot cook for 24 hours—and let's be real, most of us have jobs—you have to buy.
Look for Bonafide Provisions or Kettle & Fire. Bonafide is usually found in the freezer section. Why? Because it doesn't have the preservatives and shelf-stable junk that the stuff in the aisle has. Their "No Salt Added" chicken broth is legit. It’s literally just bones, water, and organic veg.
Another trick? Look for "Stock" instead of "Broth." Generally, stock is made from bones and is unseasoned, whereas broth is made from meat and is seasoned. It’s not a hard-and-fast rule, but it’s a good starting point when scanning the shelves at Whole Foods or Sprouts.
Practical Steps to Take Right Now
Start by replacing one cup of coffee a day with a mug of warm broth. If the lack of salt bothers you, don't go back to the boxed stuff.
- Add Potassium-Rich Spices: Use garlic powder and onion powder (not garlic salt!).
- Incorporate Seaweed: Drop a small piece of Kombu into your broth while heating. It adds natural glutamates and a "salty" ocean flavor without a massive sodium load.
- Freeze in Portions: Use a silicone ice cube tray. Pop a couple of frozen broth cubes into your sauté pan when cooking veggies. It adds depth and moisture without oil.
- The "Half-and-Half" Method: If you’re transitioning, mix half a cup of regular broth with half a cup of low salt bone broth. Slowly change the ratio over a week.
Drinking this stuff isn't a miracle cure. It won't fix a broken leg or make you live to 150. But as a tool for hydration and amino acid support, it’s hard to beat. Just stop paying for overpriced salt water. Your kidneys—and your wallet—will thank you.
