ONE A DAYEnergy Daily Essentials Multivitamin, Energy Supplement to Support Mental Alertness and Immune Health with Vitamins A C, D, E, Zinc and Caffeine, 120 Count

Have been taking these for years and appreciate the balance of daily vitamins it has in a convenient once-a-day form. Only complaint is that it often goes out of stock for prolonged periods of time (amazon and other local retailers alike), so I generally keep an extra bottle or two on hand. But it's one of the few daily multis that generally doesn't upset my stomach, doesn't leave a weird after taste, and I also appreciate the bit of caffeine in the morning as I'm not a coffee drinker. Overall good product I plan on using for years to come.

I bought these to try, because my energy level seemed to be really low. Have only taken these 2 days, before work, and i have so much energy now. Does make me a little shaky, but I'm sure that is from the caffeine in them. Make sure you eat something with them, may make your stomach upset if you don't.

In general, this was a helpful product that did as it promised -- provided extra energy and helped me focus. Sadly, it also gave me a bad eczema flare-up. It may have been caused by the excess B12 it uses (my urine was like neon yellow or green after taking this lol). So either the B12 or another element just doesn't work for me due to apparent sensitivity issues. Otherwise, it's a good product, when taken after food. Just remember, it also contains caffeine...so I wouldn't take it with another caffeinated beverage.

This vitamin is the best MTV on a day as it gives me energy throughout the day. I can tell when I forgot to take it!

These vitamins are amazing! They give you a great boost without a crash.

I love this product.

I have only taken these for a few days but I wanted to report that I have been extremely nauseated after taking a dose with food. I also have had moderate GI issues all day after taking a dose. I am unclear what is causing the nausea/GI issues - I suspect it is either the caffeine or the Niacin or perhaps both. I took a half dose today (I cut the pill in half) and I am approx 50% better - I was hoping I would not have any side effects but unfortunately, this has not been my experience. I drink coffee daily and am used to caffeine. That said, I do remember a long time ago when I tried to take a caffeine pill, it made me sick to my stomach. I also did not have a pleasant experience with Niacin in the past either. I will take a break from these for a few days and try it again. The sad part is that I have been extremely fatigued lately and I am slowly feeling more energy by taking these, despite feeling sick to my stomach. I have taken a lot of vitamins in the past and this is very rare for me to get these types of symptoms. I am sad because I feel that these have the potential to help my fatigue!

Energy all day love these vitamins
