Thanks for sharing the article.
As the the article describes, the EFSA has put an upper limit to the amount of vitamin B6 that nutritional supplements can have. This upper limit is set at 21 mg of vitamin B6 (per daily intake).
This upper limit is based on the tolerable upper intake limit of 25 mg vitamin B6 per day, that they've set in 2006. You can find it here. The limit for supplements is a bit lower than the TUL, as we get vitamin B6 through our daily diet as well and the supplements add to that.
Jake provides a max of about 0.5 mg of vitamin B6 per product, this differs a bit per product. The daily intake adds up to about 1.5 mg of vitamin B6 per day. Please note that this is well below TUL (as well as the upper limit for supplements, which do not apply for Jake as Jake is food and not supplements).
What I should add, is that the EFSA have quite recently upped the PRI (recommended intake) a littlebit, to 1.7 mg per day. We'll therefore update the products soon, so that each version of Jake will provide the higher amount of 1.7 mg vitamin B6 per day.
Hope this covers it. Let me know if you have any questions!
