Lemoniada konopna z arbuzem i CBD: letni drink

Watermelon in lemonade does three things at once: it colors, sweetens without adding sugar, and provides lycopene. A teaspoon of hemp oil adds omega acids, and at the same time, fat, without which lycopene is poorly absorbed. CBD oil drops are the third element that transforms an ordinary drink into something to be enjoyed in the evening, rather than on the go. The entire recipe takes ten minutes and requires nothing beyond a blender and a strainer. Below you will find proportions for two large glasses, a method to combine oil with a watery base, and what studies show about the absorption of fatty ingredients. I will also state clearly what this text does not do: it does not provide a dose of CBD.

KEY INFORMATION
• Arbuz zawiera 4,53 mg likopenu i 30 kcal na 100 g (USDA FoodData Central, rekord 167765).
• Hemp oil contains over 80% polyunsaturated fatty acids, and the omega-6 to omega-3 ratio usually ranges between 2:1 and 3:1 (Callaway, Euphytica, 2004).
• Adding fat to a meal with lycopene increased its absorption by 4.4 times in eleven healthy individuals (Unlu, Journal of Nutrition, 2005).
• EFSA established a provisional safe dose of CBD at 0.0275 mg per kilogram of body weight per day in 2026, which is about 2 mg for a person weighing 70 kg.

Why do watermelon and hemp oil go well together in a drink?

Because one works worse without the other. Watermelon is one of the strongest sources of lycopene in fruits: the USDA FoodData Central database lists 4.53 mg of lycopene, 30 kcal, and 8.1 mg of vitamin C per 100 g of raw flesh (record 167765). Lycopene is a lipophilic pigment, so it needs fat for absorption, and watermelon has 0.15 g of fat per 100 g, which is practically zero.

The scale of this effect was measured by a team Unlu (Journal of Nutrition, 2005) in two crossover studies involving eleven healthy volunteers. Adding 150 g of avocado to tomato salsa increased the area under the curve of lycopene concentration in triglyceride-rich lipoprotein fractions by 4.4 times within 9.5 hours after the meal, and beta-carotene by 2.6 times. The flesh of the avocado and the avocado oil itself worked the same way, so a teaspoon of any oil serves the same purpose in the drink as the fatty fruit.

For the absorption of lycopene, any fat would suffice, but hemp oil adds something more. Callaway (Euphytica, 2004) It is reported that hemp seed oil contains over 80% polyunsaturated fatty acids, and the omega-6 to omega-3 ratio usually ranges from 2:1 to 3:1. The author himself calls this ratio optimal for human health, but this is his formulation, not a recommendation from any institution: neither WHO nor EFSA indicate a single correct value for this ratio. There is also a purely culinary reason. The nutty, slightly grassy taste of hemp oil balances the sweetness of watermelon better than neutral rapeseed oil.

What is known about CBD in a drink with fat?

The fact is that fat in a meal changes exposure to cannabinoids, and we do not know what amount of CBD is safe for everyone. These two points are worth separating, as they often merge into one sentence about "better bioavailability" on the internet.

The first was measured by a team Zgaira (American Journal of Translational Research, 2016). Oral administration of lipids together with cannabinoids increased systemic exposure to CBD threefold in rats, and to THC by 2.5 times, compared to a fat-free preparation. The authors considered the affinity of cannabinoids for rat and human chylomicrons to be comparable, which they believe allows for similar expectations in humans. This is still an animal study and should be read as such.

The second point is more recent. The panel of EFSA on nutrition and novel foods established a temporary safe dose of CBD in 2026: 0.0275 mg per kilogram of body weight per day, which is about 2 mg per day for a person weighing 70 kg, with an uncertainty factor of 400. This value applies only to supplements with at least 98% purity of CBD, without nanoparticles. The panel also states that the safety of CBD cannot be established for individuals under 25 years of age, pregnant women, breastfeeding women, and those taking medications.

Therefore, this recipe does not specify the number of drops or milligrams per glass. You measure the amount according to the description on your oil's packaging, and if you are taking any medications, consult your doctor or pharmacist first.

We noticed a purely practical thing in the tests: oil dripped onto ready-made lemonade remains on the surface as a visible oily layer, while the same oil mixed earlier with lemon juice disperses throughout the drink. This is an observation from the kitchen, not a measurement, but the difference is visible to the naked eye.

Czego potrzebujesz na dwie szklanki?

The list is short and everything fits in a regular grocery store. Buy ripe watermelon, as its sweetness determines how much honey will need to be added. You can substitute lemons for limes if you prefer a sharper citrus aroma.

• 300 g of watermelon flesh, without skin and seeds
• juice from 2 lemons or 3 limes, about 80 ml
• 1 teaspoon of cold-pressed hemp oil
• 200 ml zimnej wody mineralnej, gazowanej lub niegazowanej
• 1-2 teaspoons of honey or maple syrup, to taste
• a handful of fresh mint
• ice for glasses
• CBD oil 5%, in the amount specified on the packaging by the manufacturer
• opcjonalnie plasterek imbiru i szczypta soli morskiej

Instead of oil, you can use 50 ml of hemp drink from seeds. The effect is different: the drink provides a creamy, milky consistency and a milder taste, while the oil leaves the lemonade clear and distinct. Add honey at the end and after tasting, as the sweetness of watermelon changes with the season and between individual fruits: with a ripe fruit from the height of summer, often half a teaspoon is enough for a pitcher, while with a pale one from the beginning of the season, two are needed. Chill the mineral water beforehand, as ice added to a warm base will dilute the drink.

How to make hemp lemonade step by step?

The whole process takes ten minutes, half of which is spent blending and straining the watermelon. The order matters only in one place: you combine the oil with lemon juice before it goes into the pitcher, and you add the CBD oil at the very end, directly into the glass.

1. Cut 300 g of watermelon into pieces and blend for 30 seconds. Strain through a sieve over a jug. You can skip the sieve, then the drink will be thicker and retain more fiber.
2. Juice two lemons. In a small glass, whisk a teaspoon of hemp oil with two tablespoons of this juice for half a minute until the liquid becomes cloudy.
3. In the jug, combine the watermelon juice, the rest of the lemon juice, the oil emulsion, mineral water, and honey. Stir with a long spoon or shake in a closed shaker for 10 seconds. Taste and adjust: more lemon for acidity, more honey for sweetness.
4. Fill two large glasses with ice and pour in the lemonade. Add a few mint leaves and gently crush them with a spoon to release their aroma.
5. Add CBD oil to each glass in the amount indicated on the package and stir for a few seconds. Garnish with a wedge of watermelon and a slice of lemon, and drink within fifteen minutes while the beverage is cold.

How to modify this recipe for a different flavor?

The base of fruit and acid allows for many substitutions. Strawberries instead of watermelon, 150 g of fresh or frozen, provide a more pronounced sweet-sour profile and a darker color; this version pairs better with hemp drink than with oil alone. If you want a stronger mint version, throw about fifteen mint leaves into the blender along with the watermelon and strain everything together. Blended mint colors the drink greenish and releases its aroma more strongly than leaves crushed in a glass, but it loses it after an hour in the fridge.

The recovery version after training in the heat is based on sparkling water, a pinch of sea salt, and a tablespoon of banana puree instead of part of the honey. The bubbles carry the mint aroma more strongly than still water, so use less mint then. If you prefer something thicker and more filling, instead of lemonade, make green smoothie with hemp seeds, where the fat and fiber come from the seeds themselves. Hemp oil also works well in drinks without fruits, for example in cold brew z olejem konopnym, where its nutty note plays with the bitterness of coffee instead of sweetness.

Frequently Asked Questions

Does hemp oil mix with lemonade?

By itself, no. The oil is hydrophobic and when dropped into a finished drink, it collects on the surface. Whisking it beforehand with two tablespoons of lemon juice creates a cloudy, temporary emulsion that disperses throughout the lemonade and lasts for a few minutes. A vigorous shake in a shaker works similarly.

How much lycopene does a watermelon have?

The USDA FoodData Central database reports 4.53 mg of lycopene per 100 g for raw watermelon (record 167765). This is more than in raw tomatoes, where the same database notes 2.57 mg per 100 g (record 170457). Therefore, 150 grams of pulp per glass is about 6.8 mg of this pigment.

Does the fat in the drink change the absorption of CBD?

In rats, it clearly did. In the study by Zgair (2016), oral administration of lipids together with cannabinoids increased systemic exposure to CBD threefold compared to a fat-free preparation. The authors considered the affinity of cannabinoids for human chylomicrons to be comparable to that of rats, so a similar trend can be expected in humans, but this work does not present any human studies.

How many calories are in a glass of such lemonade?

One hundred and fifty grams of watermelon per glass is about 45 kcal, based on USDA values for raw pulp (30 kcal per 100 g, record 167765). A teaspoon of any oil adds about 40 kcal. The rest depends solely on how much honey or syrup you add.

Can the CBD lemonade be made a day in advance?

Yes, for the base: watermelon juice with lemon juice will last a day in the fridge in a closed jar. Add the CBD oil only to the glass, just before serving, and drink the beverage within an hour or two. The oil diluted in a watery mixture loses freshness faster than in a tightly sealed bottle.

Is such a drink suitable for everyone?

No. The EFSA panel stated in 2026 that the safety of CBD cannot be established for individuals under 25 years of age, pregnant and breastfeeding women, and those taking medications. If you belong to any of these groups, make this lemonade without CBD oil, and consult your doctor about the decision to add it.

You will find oils with different concentrations of CBD in our the oils category. We do not have cold-pressed hemp oil or hemp seeds for sale.
