About

The purpose of this study is to evaluate the efficacy of hydrolyzed collagen in osteoarthritis.

Full description

The current study is part of a larger project called the CalGo-project. The overall purpose of the study is to use bone meal from salmon to promote skeletal health. Specifically, the potential for hydrolyzed collagen type II derived from salmon bone meal in ameliorating pain, stiffness and function in participants diagnosed with osteoarthritis will be evaluated over a time period of 6 months. Past literature indicates that collagen derivatives may be a potential supportive strategy in people suffering from osteoarthritis. Osteoarthritis is a common but complex joint disease with significant unmet medical needs, as there are currently no disease-modifying drugs available. Osteoarthritis represents a global health burden and the only curative treatment when pain becomes unmanageable, is joint replacement.

The dimensions of pain, stiffness, and function will be evaluated using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC 3.1). Plain x-rays with Kellgren-Lawrence grading will be employed to classify the severity of osteoarthritis. 100 potential participants will be screened for eligibility. Participants who meet the eligibility criteria will be randomized in a double-blind manner to receive 10 capsules daily of hydrolyzed collagen type II (a total of 5000 mg), 10 capsules daily of salmon bone meal, or 10 capsules daily of placebo.

---

98 participants in 3 patient groups, including a placebo group

Hydrolyzed Collagen type II

Active Comparator group

Description:

10 capsules daily of hydrolyzed collagen (CH) type II is taken per orally. Each capsule contains \~500 mg of CH. Once or twice daily dosing. Duration: 6 months.

Treatment:

Dietary Supplement: Hydrolyzed Collagen

Maltodextrin

Placebo Comparator group

Description:

10 capsules daily of maltodextrin is taken per orally. Each capsule contains 500 mg of maltodextrin. Once or twice daily dosing. Duration: 6 months.

Treatment:

Other: Placebo

Unhydrolyzed Collagen type II (Salmon bone meal)

Experimental group

Description:

10 capsules daily of salmon bone meal enriched with vitamin D3 is taken per orally. Each capsule contains 300 mg of maltodextrin, 200 mg of salmon bone meal (10 capsules = 2000 mg salmon bone meal = 340 mg elemental calcium in the form of microcrystalline hydroxyapatite), and 4 micrograms of vitamin D3 (10 capsules = 40 micrograms of vitamin D3 = 1600 IU).

Treatment:

Dietary Supplement: CalGo
