Feeling tired all day is rarely about sleep alone. Water, sugar, coffee, vitamin D and iron all play a part. Here are 6 reasons, what the research found, and the simple fix.

You are short on water, not only on sleep
Lose just 1.5% of your body water, and you feel more tired.
In one study, young men who lost about 1.5% of their body water felt more tired, even at rest, and made more mistakes on attention tests. In another, young women who lost 1.4% found it harder to concentrate, and simple tasks felt harder. In the UAE heat and dry AC, that happens more easily than you think.
With BOLDBOLD makes water something you want to drink. One sachet in 0.5 to 1 litre of cold water, and the bottle gets finished.
The 3 pm sugar fix makes it worse
After sugar, people feel more tired, not less.
Researchers pooled 31 studies with 1,259 people. Sugar did not lift mood at any point. Within the first hour, people felt more tired and less alert than people who had a drink with no sugar. The sweet drink you reach for at 3 pm sets up the next dip.
With BOLDBOLD has no added sugar and no caffeine. It is sweetened with stevia.
More coffee is not more energy
Caffeine hides the tiredness signal. It does not remove it.
Through the day, your brain builds up a natural tiredness signal. Caffeine sits in the spots where that signal should land, so you feel awake for a while. The signal is still there, waiting. And coffee is not a source of the 5 nutrients that matter here.
With BOLDMagnesium, vitamin C, B5, B6 and B12 contribute to a reduction of tiredness and fatigue. BOLD has all 5 in one sachet.
You get less sun than you think
Sun through a window makes no vitamin D.
Your skin makes vitamin D from direct sun. Glass blocks the part of sunlight that does it, so a bright office or a car does not count. Across 35 studies of more than 28,000 healthy people in the UAE, the average vitamin D level was below the level doctors call deficient. In one trial, tired adults who were low on vitamin D got one large dose. 4 weeks later, 72 in 100 felt less tired, against 50 in 100 who got a dummy pill.
With BOLDEvery BOLD sachet has vitamin D, 30% of your daily reference, with 200 mg of calcium. Vitamin D contributes to normal absorption of calcium and phosphorus.
Your iron can be low without you knowing
Low iron can make you tired, even when a basic blood test looks normal.
Iron helps your red blood cells carry oxygen around your body. In one trial, women who were tired and low on iron, but not anaemic, took iron every day for 12 weeks. Their tiredness dropped by 48%, against 29% for women on a dummy pill. Low iron is the most common nutrient gap in the world, and women lose iron every month.
With BOLDBOLD has no iron. It has vitamin C, and vitamin C increases iron absorption, so drink it with a meal.
The fix: 2 sachets a day
Two sachets give 50% to 60% of your daily reference of all 5.
The fix is simple: more water, less sugar, and the 5 nutrients that contribute to a reduction of tiredness and fatigue. Two BOLD sachets a day, the most the pack allows, give you 50% of your daily magnesium and 60% of your vitamin C, B5, B6, B12 and D.
