I think it's very much worth pointing out that it DOES contain phytoestrogens regardless if it's enough or not to harm you but it will affect different people in different ways. What perked my interest was that on the first page of this thread a poster claimed that the recommended dose was 3.6g per day but that he/she was experimenting with 25g per day, raising to 50g per day and then following up with 120g per day. Correct me if I'm wrong but if other posters or readers now think that it's fine to take 35 times the recommended amount of soy lecithin per day then I think it's worth noting what COULD happen in these circumstances. But anyway, your input has been noted and indeed appreciated. Have a nice day ��
In regards to PA from lecithin granules, you're getting 4-8% PA, and the minimum amount of PA you really want to ensure you're getting 750mg PA is 18.75g. Quit a few of us have doubled that amount, give or take a bit, with success, but of course there's a limit with anything. Their mention of 3.6g was the max recommended dose for Phosphatidic Acid (PA), not soy lecithin. And it appears to me that he was mentioning that dose in regards to sunflower lecithin, not soy lecithin.
I don't believe that the amount of phytoestrogens in soy lecithin granules is of any practical/relevant concern here, so I don't think it's really worth mentioning, as it's largely irrelevant and people tend to freak out whenever they hear that something has "estrogens" in it. Hell, based on the isoflavone content of soy lecithin granules, you could have 120g of soy lecithin and still only get <19mg isoflavones, which is still far less than the 100mg (the amount that you want to stay under. Even if you take half of that 100mg, and then halve that, you're at 25mg isoflavones, which you're still under that number with 120g of lecithin granules, although I wouldn't even recommend that much lecithin, as it's a waste of money IMO, a ton of calories/fat, and will likely bother your stomach with that high of a dose. That's 4.8-9.6g PA, way more than the 1.5g. Even if you wanted 1.5g PA (2x the studies amount), you're looking at 37.5g granules, and even if you wanted to double that, you're at 75g lecithin granules.
So if you quadrupled the effective PA dose (750mg) from lecithin granules (assuming 4% PA content), and divided the isoflavone number previously mentioned by 4, you're still at less than 1/2 of the isoflavone content.
Again, 750mg PA from lecithin granules should give you ~3mg isoflavones, or 1/33 the 100mg number mentioned. Even doubling that, or a bit more, should not be cause for concern.
With that in mind, is it really worth mentioning? Yes, it's a nice fact to know, and is technically true, but should I go around telling people that tomatoes do indeed contain formaldehyde every time they someone asks if they should have a salad or two?
