2025-12-18 16:32:28
Faced with symptoms such as polydipsia, polyuria, abdominal distension, hair loss, and asthenia caused by canine Cushing’s syndrome, owners are often filled with worry and always want to find a mild auxiliary conditioning method for their sick furry companions.
As natural active ingredients extracted from flaxseeds, flax lignans have excellent antioxidant and anti-inflammatory properties. Secoisolariciresinol diglucoside (SDG) is a member of flax lignans and serves as the most critical active component in flax lignans. It can help alleviate the oxidative stress damage caused by Cushing’s syndrome and reduce the side effects of excessive cortisol secretion on body tissues, thus providing a reassuring safeguard for the daily conditioning of dogs.
Healthkintai® is an experienced manufacturer and supplier of SDG powder. We mainly provide the specifications with the purity of 20% and 40%. If you are planning to carry out R&D for pet health products, please contact us at health@kintaibio.com.

Flax lignans for dogs
Are Flax Hull Lignans Safe for Dogs?
Flaxseeds have been used in many commercial pet food formulas. The Association of American Feed Control Officials (AAFCO) does not restrict flaxseeds in pet products, which means they’re recognized as safe when used properly.
Flax lignans are the extract of flaxseeds, so if used in the dogs’ supplements at recommended dosages, they are generally considered safe.
Benefits of Flax Hull Lignans for Dogs
Balances Hormonal Levels
Flax lignans (SDG) are excellent in regulating hormone levels in the body, so they are particularly suitable for dogs with Cushing’s syndrome. These compounds are phytoestrogens that can mimic the effects of the body’s natural estrogen to balance hormone levels.
For dogs experiencing excessive shedding, hair loss, or skin issues caused by hormone fluctuations related to the adrenal glands, this property of lignans can provide significant improvement.
This is especially important for spayed or neutered pets. Restoring hormonal balance enhances their overall health, including boosting metabolism, strengthening the musculoskeletal system, and improving cognitive function.
Makes the Coat Shiny
Firstly, flax lignans can balance the hormone levels, reduce damage to hair follicles caused by hormonal fluctuations, help hair follicles restore their normal hair synthesis function, and make newly grown hair healthier and stronger.
Secondly, omega-3, which coexists with flax lignans, can hydrate the skin and hair follicles to create a healthier environment for hair growth.

Boosts Immune System
Flaxseed lignans are natural antioxidants that can eliminate harmful free radicals in dogs and prevent these radicals from damaging the structure and function of immune cells.
As phytoestrogens, lignans can also gently modulate the activity of immune cells in dogs. On one hand, they enhance the phagocytic capacity of macrophages, facilitating the rapid elimination of foreign substances such as bacteria and viruses. On the other hand, they boost antibody production and enable dogs to initiate immune responses more quickly upon exposure to pathogens.

The Combination of Melatonin and Lignans for Dogs
When lignans and melatonin are used together in dogs, they can produce a synergistic effect. Lignans help regulate the dog’s hormone levels, while melatonin provides a calming benefit by reducing cortisol production.
The combination of lignans and melatonin is the best treatment for Cushing's disease because they are both natural and less costly compared to other synthetic drugs and treatments.

The Side Effects of Flax Lignans for Dogs
Flax hull lignans (SDG), commonly used for Cushing’s disease, are generally safe at recommended doses.
However, their high fiber content may cause mild gastrointestinal upset, such as diarrhea or increased stool volume, and their phosphorus content may be a concern for dogs with kidney issues. Otherwise, serious side effects are rare.
