There's a reason your grandmother's broth tasted different from anything you can buy at a grocery store. She didn't rush it.
At HOTRO.ca, we slow-simmer our bone broth take up to two days to cook and bag — and there's a very good reason for that. Time is the ingredient most commercial broths skip. It's also the one that matters most.
What Happens During a Two day Cook?
Bone broth isn't complicated — but it is patient. When high-quality bones are submerged in water with a splash of apple cider vinegar and left to simmer low and slow, something remarkable happens over time.
In the first few hours, proteins begin to denature and surface impurities rise — these get skimmed away, leaving a cleaner, clearer broth.
By hours 6–12, collagen from the connective tissue begins breaking down into gelatin. This is what gives a properly made broth its signature jiggle when chilled.
Between hours 12–24, the marrow releases its fat-soluble nutrients, and the bones themselves begin yielding calcium, magnesium, and phosphorus into the liquid.
In the final stretch — hours 24 to 48 — the broth deepens. Amino acids like glycine, proline, and glutamine reach their peak concentration. The flavour becomes richer, rounder, and more complex. This is where the real nourishment lives — and why 48-hour broth is particularly powerful for gut health.
A broth simmered for 2 hours simply cannot replicate this. The chemistry hasn't had time to complete.
Why Most Commercial Bone Broths Cut Corners
The economics of food production push toward speed. Pressure cookers can produce a passable broth in 3–4 hours. Some manufacturers use collagen additives to simulate the texture of a long-simmered broth without the time investment.
The result looks similar on the label. It isn't the same in the cup.
True 48-hour bone broth requires dedicated equipment, careful temperature management, and a commitment to doing things the slow way. It's not scalable at industrial volumes — which is exactly why we keep our batches small.
The Nutritional Case for Going Long
Research on collagen hydrolysis and amino acid extraction consistently shows that longer simmering times yield higher concentrations of beneficial compounds, including:
- Gelatin — supports gut lining integrity and digestive comfort
- Glycine — aids liver detoxification, sleep quality, and muscle repair
- Proline — essential for collagen synthesis and skin elasticity
- Glutamine — the primary fuel source for intestinal cells
- Calcium, magnesium & phosphorus — bioavailable minerals from the bones themselves
How HOTRO.ca Does It
Our bone broth is made in Gibsons, BC on the Sunshine Coast, and also in Vancouver, in small batches from ethically sourced bones. We simmer low and slow — up to 2 days depending on the variety — with no shortcuts, no fillers, and no artificial flavour enhancers.
Every batch is crafted to gel. If it doesn't jiggle when chilled, it didn't simmer long enough. Ours does.
Whether you're sipping it straight as a daily ritual, using it as a cooking base, or following one of our 10-Day or 3-Week Reset programs, you're getting the real thing — made the way it was always meant to be made.
The Bottom Line
If you're going to drink bone broth for its health benefits, the simmer time matters. A lot. Forty-eight hours isn't a marketing number — it's the threshold where broth becomes something genuinely different. It's also the foundation of everything we know about bone broth for gut health.
Slow is the point. Slow is the product.
