GLA for Healthier & Happier Pets

The ONLY FDA-approved source of GLA for use in dog food in the US

The FDA recently approved the use of SONOVA® GLA safflower oil as a safe and nutritious pet food additive

GLA Health Benefits

Bone & Joint

Mobility related arthritic conditions have been shown to respond favorably to gamma-linolenic acid (GLA) supplementation. Adding GLA to the dogs diet increases levels of the metabolite DGLA. DGLA is a precursors to several types of eicosanoids that have anti-inflammatory effects.14

Weight Control

Help shape your dog’s body with gamma-linolenic acid (GLA). Obese and overweight animals are more prone to many diseases, such as diabetes and heart disease. Clinical evidence shows that supplementation with GLA helps manage these diseases. Stay lean with GLA!

Extra weight also makes them more likely to develop arthritis and become prone to knee and hip injuries. A landmark study of 48 Labrador retrievers done in 2005 discovered that Labs who were overweight lived two years less than those who were lean! 6, 7, 8

Immune Support

Essential to your dog’s overall health and well-being – gamma-linolenic acid (GLA) can help support a robust immune system allowing your dog a more active, happy life. 5

Skin & Coat

Help improve shine and coat health with gamma-linolenic acid (GLA). GLA can improve skin and coat conditions and overall dermatological condition in dogs and is recognized as an effective agent for symptoms such as pruritus, scaling, erythema, self-trauma, and dryness.11, 12, 13

What is GLA?

Gamma-linolenic acid (GLA), the primary active component of SONOVA® GLA safflower oil, is an omega-6 fatty acid found in only a handful of plant-based oils, such as borage, evening primrose, black currant, and now SONOVA® GLA safflower oil. With a long history of use in pet foods and supplements, there is clinical evidence that GLA may impart multiple measurable health benefits for pets. The historical source of GLA has been borage oil, which is no longer approved for use in pet foods in the USA. SONOVA® GLA safflower oil is approved by the FDA as a food additive ingredient for dog food, and is now listed in the Code of Federal Regulations.

About SONOVA® GLA Safflower Oil

SONOVA® GLA safflower oil contains a minimum of 40% GLA, which is 2 to 4 times greater than current commercial sources, making it the most concentrated and cost-effective plant oil source of GLA commercially available. SONOVA® GLA safflower oil is the only FDA-approved source of GLA that can be added to pet food formulas as a source of omega-6 essential fatty acids (EFAs), which are recognized for their nutritional role for proper growth, immune system support, weight control, and the maintenance of healthy skin and coat.

Formulation and Target Daily Intake

SONOVA® GLA safflower oil is intended for use in pet food as a source of essential fatty acids. The maximum target intake of SONOVA® 400, Arcadia’s 40% GLA safflower oil, for dogs is 86mg/kg of body weight per day. This dose provides 31% of the target daily intake of omega-6 essential fatty acids (GLA plus LA) for adult dogs (NRC 2009).

Clinical Benefits of GLA

SONOVA® GLA safflower oil provides a source of omega-6 fatty acids, GLA and linoleic acid (LA), which are recognized for their nutritional role in pet care for proper growth, immune system support, weight control, and the maintenance of healthy skin and coat. While it is an excellent source of GLA, SONOVA® GLA safflower oil has the added benefit of containing LA to help meet the AAFCO recommended minimum dietary requirements.

Numerous clinical studies have clearly demonstrated the value of GLA and EFAs for improvement of skin and coat, and control of pruritus and other dermatological conditions.1,2 Akin to human studies, mobility-related arthritic conditions and inflammatory bowel disease have been shown to respond favorably to GLA and EFA supplementation.3,4

Clinical efficacy relates to the pronounced and well studied pathways by which both GLA and EPAs are converted to beneficial anti-inflammatory eicosanoids. As with humans, GLA supplementation in pets may be useful in the management of other diseases, including diabetes, immune system disorders, and obesity. A recent clinical trial of GLA in humans demonstrated a 73% reduction in weight regain after significant loss.5 Two animal studies presented similar results.6,7
