Frequently Asked Questions


Our flaxseed hulls have a shelf life in excess of 3 years. The actual shelf life is much longer, but we list 2 years from the manufacture date on the bottles to be conservative. You do not need to refrigerate our flaxseed hulls. This is different than whole flaxseed. Whole flaxseed can last many years without refrigeration until you grind it. Once you expose the embryo to the air, you must refrigerate it, and even then the shelf life is only 1 year. This is one of the many reasons our flaxseed lignans are preferred over regular flaxseed.
The recommended dosage for dogs is 1-2 mg per pound of body weight; however, we always recommend consulting your veterinarian as well. For 10 lb dogs, give 10-20 mg of SDG lignan or HMR lignan daily. For 20 lb dogs, give 20-40 mg of SDG or HMR lignan daily. For 40 lb dogs, give 40-80 mg of SDG lignan or HMR lignan daily. The capsules can be opened and sprinkled onto dog food. The capsules can also be placed in a pill pocket, a piece of meat or cheese, etc. If your dog is taking flaxseed lignans, a probiotic like yogurt can help with absorption. Open the capsule and sprinkle the powder into a small amount of yogurt with live and active cultures.
The lignan content in Flaxseed hulls can vary between 3-5%. This depends on growing season and growing conditions. We have offered 630 mg, 690mg capsules and 750 mg capsules. The capsules of flaxseed hulls are 100% pure flaxseed hulls. There are no chemicals used in the separation from the seed embryo and nothing else has been added. Therefore the lignan content in each capsule can be from 3% (18 mg) to 5% (31.5 mg) in the 630 mg capsules and 22.5 mg to 37.5 mg in the 750 mg capsules. We use 30 mg as a general rule of thumb since that is an average of 4% of the 750 mg capsule.
This is because of the type of flaxseed used. Sometimes we are able to obtain golden flaxseed and sometimes we are able to obtain brown flaxseed. They both have the same nutrient content and they both have the same shelf life. They are both high quality flaxseeds grown in North America. Because this is a natural product, the color may vary.
The flaxseed contains two parts: the hull and the embryo. We separate the hull from the embryo to produce pure flaxseed hulls. The lignans are found only in the hulls. Thus, the hulls are more concentrated with lignan than whole flaxseed. Consuming flaxseed lignans provides the benefits of whole flaxseed without having to eat several pounds of it. Flaxseed hulls also have other components: they contain fiber and antioxidants. We do not use chemicals to concentrate the lignans. The lignans are concentrated solely by virtue of the hulls' separation from the embryo. Some of our product descriptions say “concentrated lignans” and others say “flaxseed hulls.” They are both the same.

Every case varies, but it is usually recommended to use lignans and melatonin in conjunction with one another because each supplement inhibits different enzymes needed to produce cortisol. Inhibiting these enzymes can effectively lower heightened cortisol levels.

Our lignans do not need to be refrigerated. It is simply recommended to store them, and your other supplements, in a cool, dry place. The only product we offer that must be refrigerated is our SAMe for liver support. These tablets are enteric coated and the bottle requires refrigeration after opening.

Studies indicate that phytoestrogens (lignans) can help balance hormones. They are powerful antioxidants that offer immune system support and studies have reported lignans can help support heart, hair, and reproductive organ health. For info on lignans for people, visit our Health Benefits Page
