However, in the last 2 years the price of the fish oil has remained constant, while the price of Schizochytrium oil was reduced by more than 2 times, so it can be hoped that in a few years improvements in the cultivation methods might cause the price of the Schizochytrium oil to match the price of the fish oil. Now the only remaining disadvantage of the oil of Schizochytrium is the price. Then it seems that either other strains of Schizochytrium have been discovered, or they have been genetically modified, and an improved oil of Schizochytrium began to be produced, with a proportion 2:1 between DHA and EPA. Some vendors still sell this old kind of Schizochytrium oil. When it has appeared on the market some years ago, it contained only DHA and a negligible quantity of EPA. The oil of Schizochytrium qualifies as a vegan oil. Krill oil is much more expensive than either fish oil or oil of Schizochytrium, so it is a choice that does not make sense. In Europe, a typical price is around $0.20 per gram of DHA+EPA. There are 3 kinds of commercial nutritional supplements with DHA and EPA: fish oil, krill oil and oil of Schizochytrium.įish oil, either from oily fishes or from cod liver is by far the cheapest. there is vegans who survive out of pasta and soda (which contributes for osteoporosis) and those who eat a superb healthy varied diet plus vegans who do not exercise (which contributes for osteoporosis) and those who do ETC. Plus not even getting into who are the vegan people being researched on osteoporosis rate. It is like the argument of omega-3 content of flaxseeds and chia being poor translated into useful chains of acid like DHA… all you have is to increase your intake on the ballpark of 160% rather than 100% from animal sources… which translate in having to eat the enormous amount of 3 tbsp of chia per day, so you can overcome the “inefficiency” as there is a big difference of having a slight lower bone density than omnivores and getting worried about having your bones broke. worrying about calcium intake is a bit mislead. What are you doing to worry about hip fracture? are you a rock climber?ĭespite all the advantages of a strictly vegetarian diet, like better stamina, endurance etc. I have already thought that I should try sometime in the future a creatine supplement, to see if I notice any change, but for now I cannot not see any cognitive differences between present and how I was before switching to an 100% vegan diet. In general, it is much more prudent to take a supplement, even when its necessity is not certain, than to not take it, because in the first case if your choice was wrong it just does not have any useful effect, while in the second case if your choice was wrong it could cause serious health problems. Some people might not need supplements for one or more of these substances, at least when they are young, while for others supplements may be indispensable, at least when they become old. Moreover, for substances like creatine, which can be produced in limited quantities by the human body, like also for DHA, EPA, choline or taurine, there may be large differences between individuals. I have no doubt about the effects of a creatine supplement on the muscles, as there the action mechanism is well understood, but I am more skeptical about the claimed cognitive effects, because the mechanism for such effects is not known yet. If we assume a 10% conversion rate for both (depends on many factors and a tad high), you get 0.24g of DHA/EPA. Basically, the study participants at the time ate so much meat that their iron levels were so high that non-heme iron is not processed.Įdit: The other thing I wanted to say is 1 tbsp of flaxseed has 2.4g of ALA and that the adequate intake of ALA is 1.6g and 0.3g of DHA/EPA. We call this a "smart drug" which changes uptake based on concentration levels. When you remove heme iron (stop eating meat), your body is able to absorb non-heme iron at the same rate. A study long ago showed that non-heme uptake was much poorer than heme iron and so the conclusion was something like "you need to eat 10x the non-heme iron" which has since become "conventional" wisdom. This conversation I think will shake down how the heme iron/non-heme iron efficacy research. The human body is incredibly adaptive and increases its efficiency of converting ALA to DHA/EPA. Turns out that a completely vegan diet, which has no DHA, is completely sufficient to sustain the body. Yes, I know, we can keep going down this rabbit hole.
