top of the line trusted quality.
I honestly don't think there is a more trusted supplement than Thorne. My Doctor put me on this years ago and it is top of the line trusted quality.

It’s Real
I had that pins and needles feeling in my hands only when I’m sleeping or like laying down so i had got the B12 Thorne one but that was only 1 mg. So it worked but it was kinda making take more ya know i didn’t want keep taking a lot to get the effect like that. But this has 100mg of b12 and then other things of course. The first take i took it 4:00am because that’s when i work i did get a headache but i also took ibuprofen 200 mg headache was gone no pin and needles feeling in my right hand but i also felt energetic and i worked so well i met goal at work. When i didn’t take it i was moving slow maybe cuz i was sluggish and didn’t get enough sleep. But the pill is large so take ya time. But also the people were right it with all these vitamins no matter how much water u intake , it does make ya pee very yellow so don’t be alarm when u see it lol but i well keep taking it . Just took it before doing this review (10:59am)no headache so far but I’m about to eat so i should be good. What I’m going to start doing is morning and nights and see how that goes

Decent vitamin B supplement
Size/ease of swallowing: it's a little on the larger side, so it can be uncomfortable to swallow, and can get stuck in my throat. My suggestion is to eat it at the beginning of a meal, so that everything else you swallow helps it go down! Flavor: the taste is a little off-putting, and is definitely less appetizing than a gummy vitamin, but it's not a terrible taste either. To echo my suggestion above, I suggest eating this at the beginning of a meal – in regards to taste, so that the rest of what you eat drowns it out! Storage/shipping: these supplements are sensitive to humidity. I live in a very, very humid area, so how relevant this is to you depends on your local climate, but for those of you living anywhere humid, heads up! I've ordered this several times now, and have found out that it's not safe to order these when it's very humid out, as they will arrive discolored and larger than they should be, so I recommend timing your order carefully. I have also learned to store the bottle in a double layer of ziploc bags from spring through fall, because if I just leave it in the cabinet with the lid on, these will again get larger, discolored, and gross-smelling – and on one memorable occasion when I left seven in a pill case (one of those days of the week things) with my other pills, several proceeded to melt into the rest of the meds. I spoke to a pharmacist about this, and she's the one who suggested both keeping the supplements in the bottle, and keeping the bottle itself in a double layer of ziploc, and that approach has worked out well ever since, so I'm passing it along in the hopes that my fellow humidity-dwellers can skip my earlier experiences!

Brand & supplement line quality
I have been taking Thorne brand supplements for a long time. Stress B-complex has really helped my mood & energy. I can tell the difference as I am not looking for a caffeine boost in the middle of the day. Do your research B- vitamins are a must for anyone to take as it also supports your nervous system & brain. I think the price point is good for a quality B vitamin.

Brings my stress and Bp down. Great to pair up with Thorne Magnesium for a good night sleep.

The item arrived quickly, which is great. However, the bottle itself looks old or like it has been stored for quite a long time. I haven’t used it yet, so I can’t comment on the effectiveness, but I do hope the quality is not affected. Just a bit concerned about the appearance.

I used to take these back in the US, been looking for them for a while and pleased they are available now. They really help with my energy and focus levels. I take one a day and i can already notice a big difference vs the other brand I was using before
