A natural fruit juice with no added sugar still contains between 8 and 12 g of sugar per 100 ml — comparable to a soft drink. kombucha is radically different.

Point-by-point Analysis
The "100% natural" trap
A natural orange juice has 9 g of sugar/100 ml. That's 22 g in a 250 ml glass — equivalent to 5 sugar cubes. Even if it's natural fructose, the glycaemic impact is real. Mūn kombucha has 0.09-1.80 g/100 ml.
Probiotics vs Vitamin C
Juice provides vitamin C from fruit. kombucha provides live probiotics and organic acids from the ferment. Different nutritional categories — kombucha does not replace whole fruit, but it surpasses juice in glycaemic profile.
Better option: whole fruit + kombucha
If you're looking for vitamin C and fibre: eat the whole fruit, not the juice. If you're looking for a refreshing drink with a low glycaemic load: kombucha. Combining them is ideal.
When to choose juice?
As a quick source of vitamin C during convalescence, for athletes at specific times, or the classic breakfast with toast. As a daily habit, whole fruit + kombucha is objectively better.
If this comparison has convinced you to try, the variety that best fits this case is Mūn Premium Flowers 250 ml.
Frequently Asked Questions
Is natural juice healthy?
It has vitamins but also a lot of free sugar (8-12 g/100 ml). The WHO recommends limiting free sugar — including that from juices.
Does kombucha have vitamins?
Smaller quantities than juice (comes from the tea and flavouring). Its value lies in probiotics, polyphenols, and organic acids.
Is it less fattening than juice?
Yes. A glass of juice = ~120 kcal. A glass of Mūn = ~10-15 kcal.
Can I drink juice and kombucha on the same day?
Yes. If you moderate your juice intake (one glass at breakfast) and drink kombucha for the rest of the day, it's a good combination.
