correct. Soy sauce is a huge topic and I have read massive boring books on its history, but it is mostly safe regarding any remaining female hormones.

negligible remaining after bacteria process it in soy sauce :

• teaspoon of soy sauce NEGLIGIBLE – 0.4 to 2.2mg isoflavones*

• half a cup of soybeans – 40 to 75mg isoflavones

• quarter cup of soy flour – 45 to 69mg isoflavones

• one 250ml glass of soy drink – 15 to 60mg isoflavones

• one 115g block of tofu – 13 to 43mg isoflavones

• one 110g block of tempeh – 41mg isoflavones

• one container of soy yoghurt – 26mg isoflavones

so soy sauce can be considered harmless

I use coconut aminos in place of soy sauce just to play it safe.
