Good reading indeed, and I personally also agree with the note on the website telling "Never exaggerate the intake of supplements, especially not under a long time since that can lead to a disturbed homeostasis with unknown side effects!". It also does not mean that what is good for your apnea performance is good for your health too.
I found quite interesting also the document about dairy products and mucus (
http://www.apneanutrition.com/mucus.pdf), where they did not manage to find any proof of negative effect of dairy products on the mucus build-up, which is otherwise mostly accepted as fact in freediving documents, books and courses. Good to know. Personally, I never observed any difference in mucus build-up with and without dairy products either.
