Hi!
Soy lecithin is mainly a food additive , and is added to improve flavour and texture , and NOT as a potential protein. Since it’s added in trace amount , there’s no safety concern with regards to estrogen.
Also, soy does not increase estrogen , it’s an ‘estrogen blocker’.
You can take it safely as estrogen in males does not get drastically affected by foods , unless you have a confirmed hormonal imbalance issue.
