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.

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!

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 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 vitamins

Most B complex mixes have vastly excessive amounts of one or more B vitamins. There is no need for a large dosage unless you have a specific diagnosed illness that calls for it, and even with water-soluble vitamins, my oncologist and I both believe that more is not always better. Everything in this B complex has a balanced. Just enough to compensate for any potential minor shortcomings, but not too much. 4 stars because i did not felt that memory kicking in.

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 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.

Focus results but…..

As an aging woman hitting their MID 30s. I really do feel like I want to be taken better care of myself, and a more mindful of ways to get my extra dietary supplements in. I felt like these did give me a boost of energy and mental clarity that is needed as a working mum of a preschooler. I like that it is only one tablet a day as I don't like to swallow too many pills, however I did find the size a little difficult. They are flavorless mostly but I didn't love the smell of the pills - that put me off a little bit. I like the results but don't love the process which is why I have a 3 star rating

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.

Not the same as Super B Complex! Read the label!

They have changed this product. No longer says Super B Complex that I have been buying for years. The label looks very similar but it's not the same product. Now it says Advanced B-Complex. They have deleted several ingredients or decreased the amount. No longer contains vitamin C, Biotin decreased to 400 mcg. I will not purchase again. They have changed many of their products to cheaper versions. Read your labels!
