# Vitamins are coenzymes: why the complete profile beats the mega dose

> No vitamin supplies calories - B vitamins are tools in energy metabolism, and the chain is only as fast as its weakest link. What research shows about cofactors, the food matrix and inulin, and how WOO® Metabolic in the portion box is set up.

Vitamins do not supply energy. They are coenzymes - the tools without which the body cannot release the energy in food at all. Chronic tiredness is often not a calorie problem but a tooling problem.

## Vitamins are tools, not fuel

From a bite of bread to usable ATP runs a chain of enzymatic reactions, and almost every one needs a vitamin as a helper. **Thiamine (B1)**, as thiamine pyrophosphate, activates pyruvate dehydrogenase, the gate between glycolysis and the citric acid cycle. **Riboflavin (B2)** sits inside FAD, **niacin (B3)** inside NAD - the electron carriers of the respiratory chain. **Pantothenic acid (B5)** is the building block of coenzyme A, without which no fatty acid enters the cycle.

From that follows what no label states: the chain is only as fast as its weakest link. A single scarce cofactor throttles the whole throughput, even when everything else is abundant. That is why a complete profile makes more sense than a mega dose of one single vitamin.

## Isolated or from the plant?

Chemically, ascorbic acid is ascorbic acid, whether from a fermenter or from the acerola cherry. A study in healthy volunteers compared the two directly and found comparable uptake into plasma. The difference lies not in the vitamin but in what travels with it: polyphenols, carotenoids, organic acids. Those companion compounds are why nutrition research has spent decades studying foods rather than single substances - the synergistic effects of whole plant matrices can only partly be rebuilt from isolates.

## Where the gaps actually open up

Supply gaps are rarely dramatic and almost never sudden. They form wherever the diet becomes one-sided over weeks: while travelling, eating out, working shifts, in phases of high training volume. Surveys show only a minority reach five portions of fruit and vegetables a day, and anyone frequently on the road sits systematically below that. **Vitamin C** contributes to the protection of cells from oxidative stress and to the reduction of tiredness and fatigue. **Vitamin D** contributes to the normal function of the immune system and to the maintenance of normal bones, **vitamin K** to normal blood clotting.

## How WOO® Metabolic in the portion box puts this into practice

The box holds 30 sachets of 10 g. The difference from the tin is not convenience but decision load: the dose is measured out before the day begins - no scale, no scoop, no open tin in your luggage. One sachet in 250 ml of water, stirred well, ideally in the morning with breakfast or between 9 and 10 a.m.

Behind it stand 13 vitamins from plant sources - quinoa sprout extract, acerola cherry extract, Blakeslea trispora extract and sunflower extract - with, per portion, among others 25.6 mg vitamin C and 5.1 mg niacin, plus fruit and vegetable powders and the Care300® and Mito Beauty® extracts. The base is **inulin** at around 67 percent: not a filler but a fermentable fibre that reaches the colon intact and is fermented there into short-chain fatty acids such as butyrate. If you eat little fibre, start the first week with half a sachet. [WOO® Metabolic](/en/shop/woo-metabolic-box) is vegan, lactose-free and gluten-free.

## Frequently asked questions

**Why in the morning and not in the evening?**
The recommendation is in the morning with breakfast or between 9 and 10 a.m. The reason is practical: a cofactor complex is most useful when it is available ahead of the bulk of the day's meals - and a fixed time of day holds best as a habit.

**Does the powder replace fruit and vegetables?**
No. Food supplements are not a substitute for a balanced, varied diet and a healthy lifestyle. The formula closes gaps that arise from sport, lifestyle and eating habits.

**What separates the box from the tin?**
The same formula, a different logic. The tin lets you dose yourself, the box fixes the portion - the better choice on the road.
