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 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-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 daily vitamin

I've been using this vitamin daily for the past few weeks. So far it does what's suggested. I do feel like it gives me the boost I need to make it through the whole work day. I don't have any complaints about the size or taste of the tablet. Just an average size pill not a gel tablet. Worth a try to get your B vitamin.

Surprised by the positive results

I have been taking the B-Complex supplement for 4 days. I can truly feel a difference in my energy level and clarity of thought. I am personally very stressed in my life right now so any help i can get is a God send. I feel better. I have but two issues: it says to take with food so I have to eat at least a small breakfast thats not something i ususally do. And my urine is florescent yellow! I had to look it up to make sure everything is ok and it is. Its just the riboflavin. I will most likely purchase these again.

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 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.

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
