Stay Strong+ Joint & Muscle Powder by Metagenics

Stay Strong+ Joint & Muscle Powder by Metagenics is an unflavored daily powder combining UC-II undenatured collagen, creatine monohydrate, magnesium, vitamin C, and vitamin D to support joint cartilage integrity, muscle strength, post-exercise recovery, and connective tissue health in a single daily scoop.

Key Benefits of UC-II Collagen, Creatine and Supportive Nutrient Ingredients

• UC-II Undenatured Collagen Type II (40 mg per Serving) - A clinically studied collagen ingredient that maintains its native structure through digestion to reach the gut, where it supports immune-mediated joint cartilage health and promotes joint comfort and flexibility, with research showing a difference in as little as 7 days in clinical trials
• Creatine Monohydrate (5 g per Serving) - Delivers the clinically researched 5 g daily dose of creatine to support rapid muscle energy production during intense activity, promoting muscle strength, power output, and recovery between exercise sessions
• Magnesium as Amino Acid Chelate and Bisglycinate (100 mg per Serving) - Dual-form magnesium supports muscle function, neuromuscular recovery, and energy metabolism, with bisglycinate providing enhanced absorption and gastrointestinal tolerability
• Vitamin C as Ascorbic Acid (100 mg per Serving) - An essential cofactor in collagen biosynthesis that supports the body's ability to form and maintain collagen in connective tissue, cartilage, tendons, and ligaments
• Vitamin D as Cholecalciferol (15 mcg / 600 IU per Serving) - Supports calcium absorption, bone density, muscle function, and immune health to complement the joint and muscle support profile of the formula
• Joint Mobility and Cartilage Support - UC-II works through gut-associated immune pathways to support healthy cartilage structure and promotes joint flexibility and ease of movement during daily activity
• Unflavored Powder Format - Mixes easily into water, coffee, or a post-workout shake with no added flavors, making it compatible with any existing nutrition routine

Why This Formula Matters

Stay Strong+ Joint and Muscle Powder addresses two distinct but interconnected physiological needs, joint structural support and muscle performance, in a single daily serving by pairing UC-II collagen with creatine monohydrate. These two ingredients operate through entirely different mechanisms: UC-II supports joint cartilage health through gut-immune pathways, while creatine supports muscle ATP regeneration for strength and recovery. The addition of dual-form magnesium, vitamin C, and vitamin D rounds out the formula by addressing the cofactor needs for collagen synthesis, muscle function, and bone health simultaneously, reducing the need for multiple separate supplements.

Frequently Asked Questions

How does UC-II collagen support joints differently from collagen peptides?

UC-II is an undenatured type II collagen that retains its native three-dimensional structure, unlike hydrolyzed collagen peptides which are broken into smaller fragments. UC-II works through a gut-associated immune mechanism, where intact collagen fragments interact with immune cells to support joint cartilage health. This is a distinct and complementary pathway to the direct tissue incorporation mechanism of hydrolyzed collagen peptides.

Why is 5 grams of creatine included in this formula?

Five grams per day is the dose used in clinical research on creatine monohydrate for supporting muscle strength, power output, and recovery. This formula delivers that full research-supported dose in a single serving, supporting muscle energy production during intense activity and promoting recovery between exercise sessions with consistent daily use.

How should this product be taken?

Mix one serving into 8 oz of water or a beverage of your choice and take one serving per day, or as directed by your healthcare practitioner. Do not use if pregnant or nursing. If you are taking medications, consult your healthcare provider before use.

Is this product suitable for vegetarians or vegans?

This product contains UC-II collagen derived from chicken cartilage and is not suitable for vegetarians or vegans. Review the full ingredient list if you have specific dietary restrictions or allergen concerns.

How long does it take to notice results?

In clinical research on UC-II, participants began to notice a difference in joint comfort in as little as 7 days. For muscle strength and endurance benefits from creatine, research suggests onset in approximately 4 to 5 weeks of consistent daily use. Individual results will vary based on baseline status, activity level, and consistency of use.
