Why You'll Love StayStrong+™ 4-in-1 Collagen Whole Body Chew

If you're active or just want to move and feel better for longer, collagen is one of the most important things you can give your body. StayStrong+™ 4-in-1 Collagen Whole Body Chew delivers four targeted collagen types in one daily chew, so you can support your joints, connective tissue, and skin without adding another complicated step to your routine.*

  • Feel a difference in joint comfort in as little as 7 days*^
  • Supports your body's ability to protect your joints and maintain healthy cartilage.*
  • Supports collagen synthesis, vital for tendons, ligaments, skin, and nail health.*
  • Helps maintain joint flexibility and ease of movement during daily activity.*
  • Supports bone and immune health.*
  • Convenient, individually wrapped berry-flavored chew. No pills, no powder, no prep.
  • Non-GMO and gluten-free.
  • Satisfaction Guaranteed: Love it within 60 days or your money back.

The Science Inside

Most collagen supplements use only one type of collagen. StayStrong+™ combines four clinically studied collagen ingredients, each targeting a different area (joints, tendons, body and brain) so you get comprehensive support in one simple chew.*

  • UC-II® (Undenatured Collagen Type II) is backed by 10+ clinical studies, making it one of the most researched collagen ingredients available.* Most collagens are broken down by digestive enzymes before they can do their job. UC-II is different. It keeps its natural structure intact, meaning enough of it survives digestion to reach the gut, where it works with your immune system to support joint cartilage health.* Trials have shown a difference in joint comfort in as little as 7 days.*^
  • Fortigel® Collagen Peptides are specialized peptides that work directly in joint cartilage, supporting the body's natural collagen synthesis and joint comfort.*
  • Tendoforte® Collagen Peptides target tendon and ligament tissue, two areas most collagen formulas don't address. It supports the body's natural collagen production in connective tissue.*†
  • Verisol® Collagen Peptides work in skin and nails, supporting the body's natural collagen production for visible and structural results.*†
  • Vitamin C (25 mg per chew / 50 mg daily) helps your body form collagen, and that collagen is what supports healthy connective tissue, skin, cartilage, tendons, and ligaments.*

Together, these four collagen ingredients and Vitamin C provide whole-body support, covering joints, tendons, ligaments, skin, and nails — all in one great-tasting daily collagen supplement you can take anywhere you go.*
