Flax is highly over rated IMO. Fish oil has a higher efficacy as it contains EPA/DHA as opposed to the ALNA in flax. The majority of the biological effects of ALNA are generally attributed to conversion to EPA and then DHA via desaturation and elongation. These fatty acids generally have all of the same benefits of ALNA, and then some. In human and animal studies, ALNA successfully raises tissue levels of EPA, but the conversion rate is low (less than 10%). The remaining ALNA is either beta-oxidized for other purposes or partitioned into certain tissues, such as skin. The conversion rate to DHA is very low, so both ALNA and EPA supplementation generally fail to significantly increase tissue DHA content. It is likely that this is because DHA synthesis is regulated largely independently of tissue EPA content.
Agree, fish oil is more beneficial.
I think flax seed sucks and here is why
FLAX LIGNANS, LinumLife is a flax hull concentrate that contains 10 times more lignans than flaxseed or any other flax product. One gram contains 50mg lignans, the normal amount recommended per day. Lignans are phytoestrogens that act as buffers for stronger estrogens such as estridiol, block conversion of testosterone to DHT, and may decrease free testosterone by increasing globulin bonding. Obviously, this is a double edged sword. Although consumption of plant lignans is related to improved breast, prostate, menopausal, heart, and colon health, and a recent study reported improvement in hair loss in 9 of 10 male subjects; just as with soy, those trying to raise testosterone levels or promote growth should use sparingly. LinumLife™ contains some fiber and omega 3 oil, and has one year shelf-life if kept cool & tight. Slightly sweet taste.
