Collagen Peptides

Collagen is a structural protein that makes up about one-third of the protein found in the human body. Collagen peptides are smaller components of collagen that have already been broken down, making them easier for the body to absorb. Collagen and collagen peptides are often used for joint pain, bone health, and as an antiaging product for skin.

Quick Answer

What it is

Collagen is a structural protein that makes up about one-third of the protein found in the human body. Collagen peptides are smaller components of collagen that have already been broken down, making them easier for the body to absorb.

Rose hip, the fruit of Rosa canina, is a dietary supplement for joint health. It can alleviate symptoms of arthritis if taken daily.

Resveratrol

2 shared conditions · 318 outcomes

Resveratrol is a bioactive molecule found in plant sources such as grapes, peanuts, blueberries, and, famously, red wine. Resveratrol has anti-inflammatory and antioxidant properties that benefit cardiovascular function, glycemic control, and lipid metabolism. Although it’s promoted for lifespan extension, there’s no evidence for this in humans and limited evidence in animals.

Pycnogenol

Pycnogenol is a patented standardized extract from French maritime pine bark, rich in procyanidins and other polyphenols. B-grade evidence for chronic venous insufficiency symptoms, osteoarthritis symptoms, and blood glucose improvement. Has antioxidant, anti-inflammatory, and vasoactive properties. Note: 'Pycnogenol' is a trademarked product - other pine bark extracts (oligopin, flavangenol) may differ. Evidence quality is moderate with relatively small studies. Expensive compared to similar polyphenol sources.

Fish Oil

L-carnitine can relieve leg pain in people with peripheral artery disease (PAD) and treat some aspects of metabolic syndrome. Although it’s often also used for fat loss, its effectiveness for that is questionable.

Boswellia

Boswellia serrata is an Ayurvedic anti-inflammatory herb containing boswellic acids that inhibit 5-lipoxygenase (5-LOX). C-GRADE for asthma symptoms (small improvement, 1 study, 1879 participants) and skin elasticity (small improvement). D-GRADE for CRP (no effect). Used traditionally for osteoarthritis, asthma, and inflammatory conditions. Aflapin and 5-Loxin are standardized extracts with enhanced bioavailability. May improve osteoarthritis symptoms based on preliminary evidence. Relatively safe with good tolerability.
