Spectrum Flaxseeds are premium quality organic seeds that have been carefully selected for their nutritive content. Flaxseed is the most concentrated source of SDG lignans – which can vary from 0.7%-1.9% of seed weight, depending on seasonal variations and growing conditions. These select seeds are meticulously cleaned using a three-part process to remove low weight, broken and dirty seeds commonly found in bulk bins. Only Spectrum uses a proprietary milling process that finely slices the seed, rather than crushing it, thereby preventing the loss of valuable nutrients from oxidation. The sliced seed is immediately packaged in this light-protective pouch and then flushed with an inert gas and airtight sealed to ensure optimum health benefits and product freshness.
