I've been giving my 11 year old son Krill oil with Astaxanthan included, along Vit D (2000-4000) per day. (The Krill oil comes with 4mg of Astanxanthan.) He has OCD so I have been trying different, natural supplements. One day I realized that he was no longer walking around the house re-tracing his steps over if he "stepped wrong"...and I wondered if it was the supplements... or was it just wishful thinking and I was just missing the re-tracing...
Then one day I saw him twice re-tracing his steps after 3 weeks of nothing. I asked when was the last time he took his Krill oil, etc. He said it'd been a week. So he forgot to take it that whole week. Once he started up again the re-tracing stopped after 2 days. I was so happy to see a definite correlation!!
He also stopped chewing his shirt collars. He has anxiety and chews on the collars randomly throughout the day, to the point where he puts holes in them and I have to throw them away. That also started up again the week he forgot the supplements, but stopped within a day once he resumed. No shirt has been in his mouth since.
Some days I have him take 2 Krill oils and 2 Vit D's (2000 ea) (he was tested as Vit D deficient)...other days just one. I'm so happy to have found something that helps him.
Next, I'm going to also add Magnesium and Lugol's to his regimin. I'm hoping this will help with his forgetfullness. I've seen an improvement with the current suppl. but I'm hoping to really improve his memory even more.
