What is in flavour drops?
Four ingredients go into every bottle here: flavouring, propylene glycol as the carrier, water and steviol glycosides from stevia. The list reads the same on every flavour on this page.
Propylene glycol is the carrier. It holds the aroma in solution, which is why a quarter of a millilitre flavours a full mug, and why the drops pour thin rather than syrupy.
Steviol glycosides come from the stevia leaf and do all the sweetening. Nothing else on the list sweetens: no sucralose, no acesulfame K, no sugar alcohol.
Flavouring and water make up the rest. No sugar goes into the bottle at any stage, which is why the sugars line on the label reads 0 g per 100 ml.
How many flavour drops should you use?
Five drops is the serving on the label, about 0.25 ml, and a 50 ml bottle holds about 200. At £6.99 a bottle that works out at roughly 3.5p a serving.
One drop is 0.05 ml, so five of them come to a quarter of a millilitre. That is the figure the label prints, and it is what the servings per bottle are counted from.
The product cards suggest 3 to 5 drops, so at the lower end a bottle goes further than 200 servings. The count on this page stays with the label dose, the less generous of the two.
Start low and add. Vanilla in a black coffee reads differently from chocolate in a protein shake, and one drop more is easier to fix than one drop less.
How do you use flavour drops in coffee?
In coffee it takes 3 to 5 drops, stirred into the cup after brewing. The same dose flavours a matcha latte, a protein shake or a bowl of yoghurt.
Drops flavour without changing what is in the cup. They carry no fat and no body, so a black americano stays black and a flat white keeps its texture.
Cold drinks take the same dose. Three to five drops dissolve into iced coffee, a smoothie or a glass of water, because water is the third ingredient on the list.
Porridge, pancakes and yoghurt work the same way: drops stirred in before cooking, or added at the table.
Do flavour drops fit a keto diet?
The declaration reads 0 g carbohydrate per 100 ml, so a 5 drop serving adds nothing you need to count. Five drops is 0.25 ml of that liquid.
Sold as keto drops, they run zero across the whole table: 0 kcal, 0 g fat, 0 g saturates, 0 g carbohydrate, 0 g sugars, 0 g protein and 0 g salt per 100 ml. The sweetness comes from steviol glycosides, which are not a sugar.
How much carbohydrate fits into a day is a separate question, and it changes with the rest of the plate. Our guide to how many carbs a day on keto works through the daily figure.
Which flavour drops should you choose?
Every bottle here carries the same price, the same four ingredients and the same 5 drop serving. The choice is only about the flavour.
The flavours are Favourite Cookie, Cherry on Top, Natural Chocolate, French Vanilla and Delicious Hazelnut. Each is a 50 ml bottle at £6.99, so nothing about the decision turns on price or on the ingredient list.
What stays the same across the shelf:
- Bottle: 50 ml

Wherever you buy drops, the three lines worth comparing are the sweetener, the carrier and the serving size.
Where can you buy flavour drops in the UK?

Frequently asked questions
What are the best flavour drops?
The best flavour drops name three things: which sweetener does the sweetening, what carries the aroma and how many drops make a serving. On this shelf that reads steviol glycosides, propylene glycol and 5 drops. A bottle that answers all three is comparable with any other.
Are flavour drops sugar free?
Yes, the declaration reads 0 g sugars. Sugars free in Great Britain needs no more than 0.5 g per 100 ml, and these bottles declare 0 g per 100 ml. No sugar appears in the ingredient list either.
Are flavour drops zero calorie?
Yes, these bottles declare 0 kcal. Zero calorie is the everyday wording for it. The claim on the Great Britain register is energy free, and it allows no more than 4 kcal per 100 ml, so 0 kcal sits well inside the threshold.
Can you use flavour drops in protein shakes?
Yes, 3 to 5 drops flavour a shake. An unflavoured whey or plant shake takes the aroma without any change to its macros. The drops carry no protein of their own, only flavour.
Can you buy flavour drops in Tesco or Boots?
BeKeto flavour drops are sold from this shop. A 50 ml bottle is £6.99 here. What any supermarket or high street chain puts on its shelves changes independently of us, so check the ingredient list on whatever you find on a shelf.
Do flavour drops taste bitter?
Steviol glycosides are the only sweetener here. How sweet or how sharp a cup reads depends on the dose, so start at 3 drops and work up. Our guide to the best sweeteners for keto compares stevia with erythritol and xylitol.
Can you bake with flavour drops?
Yes, stir 3 to 5 drops in. The product cards put them in pancakes and in baking, at the same dose as in a cup. Flavouring is the first ingredient, so the drops season rather than sweeten a bake on their own.
How long does a bottle of flavour drops last?
About 200 servings of 5 drops. That is one 50 ml bottle at the dose printed on the label. One flavoured coffee a day runs a bottle to roughly six months.
Can you put flavour drops in water?
Yes, the drops are water based. Water is the third ingredient on the list, so 3 to 5 drops dissolve into a glass the same way they do into coffee. They add no colour and no fizz.
Are flavour drops vegan and gluten free?
Every card here says gluten free and vegan. Lactose free is printed on the same cards. The sweetener comes from the stevia leaf, so the sweetness is plant based as well.
