When you’re deep into a fast, the line between willpower and surrender is measured in cravings. One warm, savory cup of bone broth can make the difference between breaking early and reaching your goal, delivering protein and electrolytes without triggering a full metabolic break.
I’m Mohammad Maruf — the founder and writer behind WellFizz. I’ve spent years analyzing the nutritional chemistry, sourcing standards, and electrolyte profiles of fasting-compatible broths to separate brands that genuinely support autophagy from those that spike insulin with hidden additives.
This guide cuts through the marketing noise to deliver the best bone broth for fasting based on protein density, sodium content, ingredient purity, and convenience for real fasters.
How To Choose The Best Bone Broth For Fasting
Selecting a broth for fasting demands more scrutiny than general sipping. You need a product that supports electrolyte balance, delivers satiating protein without calorie overload, and avoids any ingredient that could break a clean fast or trigger an insulin response.
Protein Density and Collagen Content
During a fast, every gram of protein counts differently. Look for broths providing 8–16 grams of protein per serving from hydrolyzed collagen, which absorbs without digestive stress. Higher protein helps sustain muscle and curbs hunger longer than low-protein alternatives.
Sodium and Electrolyte Profile
Fasting depletes sodium rapidly, leading to headaches and fatigue. A good fasting broth should contain at least 200–400 mg of sodium per serving. Avoid products with added sugars, maltodextrin, or starches — these can spike insulin and break a true fast.
Ingredient Purity and Processing
Many broths add onion and garlic powder, which can irritate sensitive guts during prolonged fasts. Opt for brands with minimal, clean ingredients — ideally just bones, water, and perhaps sea salt. Liquid broths retain more natural collagen and flavor but require refrigeration; powders offer portability.

In‑Depth Reviews
1. Bluebird Provisions Chicken Bone Broth Powder
Bluebird Provisions stands out in the fasting category because its bone broth powder contains just two ingredients: dehydrated chicken bone broth and nothing else. With only 130 mg of sodium per serving and no onion or garlic, it’s one of the cleanest options for fasters with sensitive guts who need to avoid common irritants.
Each serving delivers 12 grams of collagen-rich protein from pasture-raised chicken bones, providing a solid protein anchor during extended fasts. The low-calorie profile (just 50 calories per cup) makes it ideal for maintaining a fasted state while still offering enough substance to dull hunger pangs.
Some users note the flavor is mild and benefits from a pinch of added salt or herbs, which is a minor trade-off for the purity. It dissolves quickly with a quick stir, making it reliable for office mornings or travel kits where refrigeration isn’t available.
Why it’s great
- Only two ingredients — no gut irritants
- Quick dissolve powder for on-the-go fasting
- Pasture-raised source with strong amino profile
Good to know
- Very low sodium may need supplementing for electrolyte balance
- Mild flavor tastes bland unless seasoned
2. Brodo Classic Variety Pack
Brodo’s Classic Variety Pack brings restaurant-quality liquid broth to your fast. Made by James Beard Award-winning chef Marco Canora, these single-serving pouches contain organic chicken, 100% grass-fed beef, and hearth bone broths, each slow-simmered to extract deep flavor and naturally occurring collagen.
The liquid format preserves gelatin content better than powdered alternatives — users report the broth gels when refrigerated, a sign of real collagen. Each 8.3-ounce pouch delivers a savory, warming experience that mimics the ritual of a meal without breaking a clean fast, provided you’re not restricting calories to zero.
Though priced higher per serving than powders, the convenience of heat-and-sip pouches and the absence of any processing aids makes this a top choice for fasters who prioritize purity and taste above all. The variety pack lets you rotate flavors to avoid taste fatigue during longer fasts.
Why it’s great
- Real liquid broth with visible gelatin content
- Organic, grass-fed, no preservatives or MSG
- Three flavor varieties prevent palate boredom
Good to know
- Higher cost per serving compared to powders
- Requires refrigeration after opening
3. Brodo Organic Chicken Broth
If you want a single-flavor liquid broth focused entirely on chicken, this is the purest expression. Brodo’s Organic Chicken Broth uses pasture-raised chicken bones simmered with vegetables and aromatics, then packaged without concentrates or preservatives. It’s particularly suited for fasters recovering from gut issues or procedures.
The flavor is noticeably cleaner than conventional broths — no apple cider vinegar tang, no excessive salt. Users report it’s easy on the stomach even during extended liquid-only periods, and the small pouch size fits neatly into a purse or work bag for quick reheating.
At the same price point as the variety pack, this is a commitment to chicken. For fasters who prefer a consistent, familiar taste profile over variety, this delivers the most authentic sipping experience in the category. The sodium level is moderate, so you’ll still want to supplement electrolytes separately.
Why it’s great
- Single-ingredient focus with no vinegar or fillers
- Gentle on sensitive stomachs during fasts
- Portable pouches ready in minutes
Good to know
- Only one flavor, which can become monotonous
- Needs additional sodium for full electrolyte support
4. Ketostat Bone Broth Protein Powder Packets
Ketostat brings the highest protein count in this lineup — 16 grams per single-serve packet of hydrolyzed beef collagen protein from grass-fed cattle. For fasters who need serious satiation, this is the most efficient protein delivery system in powdered form, dissolving easily in hot water for a rich sipping broth.
The packets are designed for zero-prep portability, making them ideal for fasters who travel or work long hours away from home. Users consistently praise the smooth taste and lack of chalkiness, noting it blends better than many collagen powders they’ve tried. A few reviewers report a faint Cheetos-like smell, but the flavor remains clean and mild.
While the protein punch is excellent, the lack of added electrolytes means you’ll need to manage your sodium and potassium separately. It’s a trade-off for a product that leans heavily into the high-protein, low-ingredients philosophy favored by strict keto and carnivore fasters.
Why it’s great
- Highest protein density at 16g per serving
- No added hormones or antibiotics from grass-fed source
- Single-serve packets for flawless portion control
Good to know
- No added electrolytes — needs separate supplementation
- Slight sediment may settle if not stirred occasionally
5. LonoLife Keto Chicken Bone Broth Powder Mix
LonoLife’s chicken bone broth powder is the entry-level choice for fasters who want a decent protein kick without committing to premium pricing. Each stick pack contains 10 grams of collagen-rich protein from grass-fed cattle bones, blended with chicory root, black pepper, and savory herbs for a more flavorful profile than plain broths.
The stick pack format makes it exceptionally easy to stash in a bag or desk drawer — just tear, pour, and stir. The flavor is notably more robust than the Bluebird or Ketostat options, which can be a plus for fasters who struggle with bland liquids during long fasts. Customer reviews consistently highlight the taste as a standout.
On the downside, the 10-stick count covers fewer fasting days than the powder canisters offer, so the per-serving cost is higher than it first appears. The protein content is lower than Ketostat’s, which means you’ll get less satiation per serving. However, for fasters on a tight budget who still want a flavorful, protein-supported fast, this delivers solid value.
Why it’s great
- Rich, savory taste that curbs cravings effectively
- Portable stick packs for desk or travel
- Affordable entry point into fasting-compatible broth
Good to know
- Only 10 servings per box — fasters may go through quickly
- Contains chicory root and herbs, not a single-ingredient profile
