I have recommended this product to friends because it does help with my Migraine.Shipping to NZ was fast, no issue there either.The product is great, its just that 30 tablets in such a large container is just wrong. I managed to fit 240 tablets into 1 container.I would be happy to buy 1 container with 240 tablets in it and save the planet some every unneeded plastic. We need to be looking after the health of the planet too.

Finally I no longer have to take 4 tablets a day. 400mg B2 was recommended by health professionals to assist with my vetibular migraines and I find it keeps symptoms at bay for the most part. Now I can take that in one tablet, so this works great for me when I go on holidays. However it loses a star for quality because it contains ingredients I do not like to take in my daily supplements and is not as cost effective as other brands like Now.

My neurologist suggested I take B2 for my migraines. He suggested 400 mg. This dose is not easy to find and very hard to find in a tablet form. Nature's Way is one of the only companies to offer 400mg in tablet form. They are very easy to swallow and this is a good quality brand. I have been taking for over a year now and I can say that definitely help with the headaches. Any time I miss a couple doses I will get small headaches so I am sold on taking these daily. I have read other reviews that complain about the size bottle used for 30 small tablets and I would agree that it seems that they could save money and material by placing them in a smaller bottle. But they bottle is shaped nicely (square) and fits in my medicine cabinet well which is nice since I usually ... MoreMy neurologist suggested I take B2 for my migraines. He suggested 400 mg.

Exactly as described. Good dose. No issues. Easy to swallow. Does the job. Reasonable price. Perfect medicine for being sick.
The only B2 supplement I've found at the high doseage my doctor prescribed! I'm taking it for migraines and overall nervous system support, and while I haven't noticed any benefit in those departments after several months, my doctor has encouraged me to stick with it. I really appreciate that there's no taste or odd coating to these. I wish I could order a larger bottle with a higher quantity.
As a migraine sufferer, my doctor recommended leveling up my B2 to see if it could help reduce my incidence of migraines. While migraines are a complex condition with many "triggers", in my personal experience I was able to lower my incidence of migraine days per month while taking additional B2. It is not a panacea for the condition, but in my case, it definitely helped.
