Benefits & Features:

• Supports joint health with Tendoforte collagen peptides.
• Tendoforte collagen peptides aid ligament and tendon health, helping you stay resilient during training, recover more comfortably after tough sessions, and keep moving when it matters.
• Glucosamine HCL and chondroitin help cartilage protection and smoother movement during daily activities, which matters.
• Boswellia delivers anti inflammatory support, helping ease training related swelling and stiffness after intense sessions, which many athletes notice.
• MSM and Hyaluronic Acid cushion joints and support smooth movement daily, and often feel reassuring.

Join-In is a concentrated joint formula bringing together Tendoforte collagen, MSM, Cissus, glucosamine HCL, chondroitin, Boswellia and Hyaluronic Acid. This blend targets inflammation and connective tissue health with a focus on fast recovery after training, and a touch more ease for post‑session days. The ingredients aren’t vegan because bovine chondroitin is included, reflecting a traditional approach some athletes prefer, and that’s okay for many. The product’s emphasis on potency and straightforward dosing makes it a reliable partner for workouts and pairs well with protein shakes or collagen peptides, or with plant based protein powder for a complete routine.

This Main Ingredient Is: Collagen (Tendoforte Variant)

Collagen is a structural protein that helps supports connective tissues and contributes to tissue integrity. This formulation uses Tendoforte collagen peptides as the active ingredient to provide a source of collagen nourishment for joints and related structures.

This form contains collagen peptides derived from Tendoforte; collagen is commonly associated with supporting the health of ligaments and tendons and is linked to maintaining connective tissue structure through normal biological processes.

What Does Collagen Do?

Collagen helps to support connective tissue health by participating in the maintenance of ligament and tendon integrity. It also contributes to the normal function of joints by supporting the tissues that surround them, in line with EFSA-inspired guidance on connective tissue health.

Overall, collagen plays a role in supporting the structural framework of joints and associated tissues to help maintain mobility during regular activity.
