Dr. Kellyann Review 2026: Bone Broth Diet for Women Over 40?

If you’ve spent any time searching for weight loss solutions, you’ve probably seen Dr. Kellyann Petrucci — the naturopathic physician known for bone broth diets, collagen supplements, and her frequent appearances on daytime TV. Her product line promises to help women lose weight, improve gut health, and restore youthful skin through the power of collagen and bone broth.

But is there substance behind the marketing? And do her products actually deliver for women over 40? We looked past the infomercials. Here’s our honest review.

Quick Verdict

Rating: 3.5/5 ⭐ | Price: From $35/month | Best For: Bone broth + collagen

Dr. Kellyann’s products address real concerns for women over 40 — collagen loss, gut health, joint pain, and inflammation. The bone broth approach has some scientific support. However, the products are pricey, weight loss claims are often overstated, and you can get similar benefits from less expensive alternatives. Solid for supplementation, but not a standalone weight loss solution.

What Is Dr. Kellyann?

Dr. Kellyann is a brand created by Dr. Kellyann Petrucci, a board-certified naturopathic physician and certified nutrition consultant. Her approach centers on bone broth and collagen as foundational elements for weight loss and overall health.

The product line includes:

• Bone Broth Collagen — powdered bone broth packets (various flavors)
• Collagen Peptides — unflavored collagen powder for smoothies and drinks
• Bone Broth Protein — protein powder made from bone broth concentrate
• Collagen Shakes — meal replacement shakes with collagen
• Lemon Sips — a lemon-flavored collagen drink for fasting support
• Supplements — probiotics, greens powders, and other wellness products

She also authored “Dr. Kellyann’s Bone Broth Diet” — a 21-day plan combining intermittent fasting with bone broth.

How It Works for Women Over 40

Dr. Kellyann’s approach targets several issues that become more prominent after 40:

1. Collagen replacement — Women lose about 1% of collagen per year after 30, accelerating during menopause. Supplementing with collagen peptides may support skin elasticity, joint health, and gut lining integrity.
2. Gut health support — Bone broth contains gelatin and amino acids (glycine, glutamine) that may help repair gut lining. A healthier gut can improve nutrient absorption and reduce inflammation-related weight gain.
3. Intermittent fasting framework — The Bone Broth Diet uses a modified fasting approach: eat clean for 5 days, do bone broth “mini-fasts” for 2 days. This form of intermittent fasting can work for some women over 40.
4. Anti-inflammatory focus — The diet eliminates common inflammatory foods (sugar, grains, dairy) while emphasizing anti-inflammatory bone broth. Reducing inflammation can help with stubborn weight, especially belly fat common during menopause.

The science behind collagen supplementation is growing but not conclusive. Some studies show benefits for skin and joints. Weight loss benefits are more likely from the calorie restriction and fasting components than from the bone broth itself.

Dr. Kellyann Pricing

The pricing is on the higher end for collagen supplements. You can find quality collagen peptides from other brands for $0.50-1.00/serving. What you’re paying for with Dr. Kellyann is the specific formulations, flavors, and the bone broth diet framework. Compared to complete programs: The Smoothie Diet costs $47 total and includes a full meal plan.
