Rated 5 out of 5 by from B for Booster I don't think I could make it through the day without this boost of energy each morning. For the past three months, I have noticed a difference in my energy level, for the better. At my age I need all the help I can get.

Rated 5 out of 5 by from Energy Boost Definitely notice a little boost in my energy level. Plus, I'm hoping that I will notice a boost in my immune system because of the C. I haven't been taking them that long but I have noticed the slight energy boost.

Rated 5 out of 5 by from Balance is Best I was getting the B12 but I was told that it was better to get all the Bs and this one came with C also! That made it even better for me.

Rated 5 out of 5 by from Great combination This is just an all around good vitamin. Lots of great ingredients. I feel such a difference since we started taking this. It is a great addition to our B12 because the doctor said we needed more than what we were taking.

Rated 5 out of 5 by from Super Stress Vitamin B-Complex with Vitamin C Super Stress Vitamin B-Complex with Vitamin C I work in customer service myself at a fitness facility where I check in everyone passing through my section of the building. Eating mostly vegan I need extra B vitamins to remain on my toes.
Date published: 2016-05-11
Rated 5 out of 5 by from Main minerals in popular fitness drinks I actually decided to try the super stress B complex because of the B vitamins it contains. Most popular fitness and sports energy drinks contain a significant amount of B vitamins which most athletes need to fuel their work out. For those who have hectic days those B vitamins play an important role in stress management. It helps that it packs a hefty dose of vitamin C all without the sugar caffeine crash one may obtain by regular consumption of such drinks. You don't have to be old, super athletic, or a certain gender to reap the benefits of this supplemental complex. Even those whose occupation are more on a mental level can focus more clearly and preform better with this supplement.

Rated 5 out of 5 by from LOVE this one for STRESS.... ...and I do know stress - DAILY - as do most of us today if we're honest! I have been taking this combo for 5 months, give or take. I only take one in the late morning and I benefit quite a lot through the day. I can't even say for sure WHEN I knew it was affecting my stress levels, and my being more 'awake & alive' during the day, but I feel truly blessed with these results. Obviously this combination could sell for FAR more money, and it would be worth it to me, no matter the cost, to continue to take it. I am more 'present' in each moment these days, and I believe that this is a direct effect of this amazing product! I always count on Swanson brands, and rarely ever need to look to a different brand for my own nutritional needs. My husband started taking this one too, and though he doesn't really KNOW it, he has become a more positive, calmer partner to me, and a very involved Dad & Grandpa! Keep this one just the way it is, and we'll keep coming back! Love me some Swanson's! God Bless!

Rated 5 out of 5 by from The extra boost I need This products just gives me the extra little boost I need to get started in the mornings. It's affordable and easy to take. I take one each morning and that is all I need to get that little burst of energy that lasts for hours. I can tell when I haven't taken one. My husband also takes this and says it doesn't upset his stomach as other B's have. The price is right and it has the effect I'm looking for, so why not?
