Great vitamin

This b complex vitamin supplement is a great addition to any vitamin regime you may be currently on! The pills are decent sized and easy to swallow. I have experienced better mood and more energy along with not being completely drained at the end of the day.

Great product without artificial dyes and flavors

I found these supplements to be exactly what I was looking for! Perfect balance of B vitamins along with the added bonus of calcium. The best part of the product was the things that they did not add. No unnecessary additives of synthetic dyes, or artificial coloring. Perfect.

Great Supplement!

I’ve been taking these for a few days now, and let me tell you I feel they are actually helping me feel less fatigued. I was really feeling exhausted and started to notice I was experiencing more energy. I can’t say about the mental sharpness just yet but so far so good with these!

B-complex tablet

The B-Complex vitamin is a small tablet. I struggle with swallowing large pills, so this size is perfect. It is a small yellow oval tablet and the container comes with 300. B-complex gives me some added energy since I work out and and there are enough tablets to last for almost a year!

I gave them a 4 star rating because I just started taking them. However, as a person who has spent big money on supplements, I decided to give these a try. They are pretty small in size and shape. Making them easy to swallow. To me they don't leave an after taste or upset my stomach if I haven't eaten. There are 300 tablets and the best thing is that they don't break the bank. Now if I don't get bit by mosquitoes next year then I'll know for sure their quality.

I hope they will lower the niacin content.

This is mostly a great B-Complex with one exception. I think it should have a lower niacin content. I am always way over the upper limit for niacin because of this mg amount.

I wanted to take a good vitamin B supplement and my husband said to get this one, the B complex. It seems to help with fatigue and energy which I like, but they smell so rancid and the taste in your mouth after taking, so gross. Just another thing that's good to take, but it almost makes me not want to! Lol.

Title is fine

I'm actually afraid to try this supplement as it smells terrible. What am I to do?

Warning: burnt my vaginal area

These burnt my whole vaginal area and it took days for me to register what was happening. I have never hurt so bad. It turns you pee a neon color. i have been to the doctor. i was wondering if it was it, and thought all the pills were out of my pillbox. i accidentally took another and it was confirmed to be the cause. i am on fire despite the meds from the doctor. i have never hurt so bad down there.

N/A

The smell of these vitamins would make anyone sick. I don't know why you would take the Super B Complex out of the clubs and now you only can only get them online, and when you go to Sams club website to order online it's always out of stock.
