Quiz: which is the most helpful for staying sharp on the job: soda, diet soda, water, coffee, tea, or fruit juice? You may be surprised at the answer.

It's a little known fact that most people have mild chronic dehydration. An estimated 75 percent of Americans are not drinking enough water, and that lack is the number one trigger for daytime fatigue. Even slight dehydration can slow down your metabolism, leaving you feeling sluggish in mind as well as body. Just a two percent drop in body water can cause trouble with short-term memory and basic math, and make it difficult to focus.

How much water is right for your body?

To see if drinking more water improves your concentration and energy, do the following. First, find your daily water goal. Take your body weight and divide it by half. This number, in ounces, is your eventual goal for daily water consumption.

For example, if you weigh 200 pounds, your eventual goal would be 100 ounces of water each day. That's about 12 eight-ounce cups. If you weigh 150 pounds, your daily water goal would be 75 ounces, or about nine cups. Remember, that is for an entire day, not just the eight hours at work.

When you've figured out your water goal, gradually increase your water intake, giving your body enough time to adjust. Any person with a history of kidney or bladder issues should first consult their doctor.

Water gives you many other benefits!

When you've neared your optimal water consumption you should start noticing physical and mental changes, such as higher energy levels and better ability to concentrate.

There are other benefits to increasing your water intake, such as weight loss. In many people, the thirst mechanism has become so weak that it's often mistaken for hunger. A single glass of water shut down midnight hunger pangs for almost 100 percent of dieters in a University of Washington study.

A Virginia Tech study of two groups on the same restricted-calorie diet showed that after 12 weeks, those who drank water before meals had lost nearly 30 percent more than those who did not drink water. When you are fully hydrated, you may also experience relief from joint pain. Some research indicates that 8 to 10 glasses of water a day could significantly ease back and joint pain for up to 80 percent of those who suffer such pains.

A California university study confirmed that employees drank more water when True Lemon was available. True Citrus products provide real lemon, lime and orange taste from real fruit. True Citrus is also convenient to take to work, because the no-mess packets don't require refrigeration.

True Citrus customers are thrilled with their positive experiences: 

"I've always been a heavy tea drinker at work during the day. But the tea stains my teeth so my dentist suggested I limit my intake of tea. For the past several months, I've switched to hot True Lemon or True Lime during the day. It is very refreshing and I now find that I prefer it over tea."

"True Lemon and True Lime are simply amazing! Eight glasses of water each day is much more enjoyable with a pack of True Lemon or True Lime. I can even add a little Splenda for a calorie-free lemonade. Thank you for bringing water to LIFE!" 
- Melissa, Marlton, NJ

"I have been drinking hot lemon water for years as a great appetite suppressant. With True Lemon it is very convenient to keep a box in my desk drawer and do not have to worry about a messy, spoiling lemon."

"I am working on cutting out the caffeine and will eventually work my way up to drinking just water, but I will never give up my True Lemon. This has been an absolute Godsend since it can be added so easily and tastes so good! As a side note, I believe the addition of this extra source of Vitamin C has been an excellent way to maintain my health and I haven't had a cold in a very long time."
