Decided to take this vitamin after listening to some well documented research on you tube. If you look up Dr John Campbell, he explains a study that is in the British Medical journal re vitamin B3 and how it can protect you from upper respiratory tract infections. Apparently a lot of people are low on this . It is well worth listening too in light of covid19.
My daughter feels much better and even sleeps better when taking this product.
A fabulous product! Am convinced these have kept my seasonal-affected disorder at bay for the last few miserable months of Dunedin winter. They also taste delicious - like oranges and sunshine.
