Hi dear!
Naturline milks are packed using aseptic packaging, which means they’re filled in a sterile environment with no preservatives. That’s why they can last up to 9 months at room temperature (around 25°C).
If your product stayed for a few days at slightly higher temperatures (27–29°C) and is still unopened, it’s generally fine.
After opening, just check the smell, color, and taste.
If anything feels off, it’s best not to consume it.
Our products are available in 1-liter, 500 ml, and 200 ml packs.
Absolutely! You can use all Naturlean milks for coffee, smoothies, desserts, and oatmeal—it all depends on your taste.
For better foam results:
Chill the milk in the fridge for a few hours
Shake the carton well before pouring
Steam between 50–60°C (higher temperatures may reduce foam quality)
Thanks for sharing your thoughts!
Plant-based milks are naturally made from nuts and water, which gives them a lighter and smoother texture compared to dairy milk.
At Naturlean , we use high-quality nuts, even above global standards. Our products contain no unnecessary additives and provide meaningful nutritional value as part of a healthy daily diet.
Our goal is simple: a clean, natural, and delicious plant-based drink you can enjoy every day 🌱

Naturlean milks are gluten-free, additive-free, and rich in natural vitamins and antioxidants. They’re generally easy to digest and suitable for people with lactose intolerance.
For specific medical conditions (digestive, hormonal, or skin issues), we recommend consulting your doctor first.
Once opened, it’s best to keep the milk in the fridge and consume it within 5 days.
Freezing may change the texture and consistency, so we don’t recommend it.
If you consume small amounts, our 200 ml packs are a great option!
We use UHT processing, which sterilizes the product and allows it to be packed in Tetra Pak cartons.
This method:
Extends shelf life
Preserves taste and freshness
Requires no preservatives
Protects the product from light and air
The expiration date alone isn’t enough. Always check the smell, taste, and appearance.
Once opened, plant milks are best consumed within 5 days and heated only up to 60°C.
Currently, we offer almond, hazelnut, oat, almond with date sugar, hazelnut with date sugar, chocolate peanut milk, and chocolate almond milk.
Good news: soy milk is coming soon! 🙏
This is totally normal!
Plant proteins are more sensitive to high heat and acidity than dairy milk.
To avoid curdling:
Keep coffee temperature below 60°C
Add milk gradually
Choose lower-acidity coffee beans
This doesn’t mean the milk is spoiled—it’s just the natural behavior of plant-based proteins 🌱
According to food safety standards, we use very small amounts of approved natural stabilizers, calcium carbonate, sodium citrate, and edible salt.
No artificial colors, flavors, or preservatives—ever.
All Naturlean products are produced in Iran using high-quality local nuts.
Yes! Tetra Pak packaging keeps the product safe from contamination and is more protective than plastic bottles.
If you’re not allergic to nuts, it’s generally safe.
For peace of mind, we recommend checking with your doctor.
No preservatives at all!
We use UHT heat treatment to keep the milk safe and stable—this is a global standard.
Most Naturlean milks have no added sugar.
We also offer versions sweetened naturally with date sugar for those who prefer a sweeter taste.
Yes—and that’s completely normal worldwide.

UHT (Ultra High Temperature) heats the milk briefly to 135–150°C for just a few seconds, then cools it rapidly.
This:
Kills harmful bacteria
Preserves nutrients and flavor
Allows long shelf life without preservatives
Perfect for plant-based milks 🌿
Hi dear! Yes, all Naturlean products are completely gluten-free.
Yes, you can absolutely use Naturline almond milk for porridge or desserts that need gentle heat.
Just keep in mind that plant-based proteins are more heat-sensitive than dairy milk, so the ideal heating temperature is around 60°C.
That’s why Naturlean milks work best for low-heat cooking and desserts, and aren’t recommended for recipes that require long boiling or very high temperatures.
After mixing the nuts with water and filtering, Naturlean plant-based milks are treated using the UHT system at around 140°C for about 3 seconds.
This process fully sterilizes the product and naturally increases shelf life—without harming nutritional value or nut quality.
Naturlean plant milks are produced without added sugar or artificial flavorings.
However, if you enjoy a slightly sweeter taste, we offer two naturally sweetened options:
Almond milk with date sugar and hazelnut milk with date sugar.
Unsweetened almond and hazelnut milks can be suitable for a keto or low-carb diet, as they contain very low amounts of carbohydrates and sugar.
For best results and personalized guidance, we recommend consulting a nutritionist.
Thanks to the UHT process, unopened products can be stored for up to 9 months at room temperature (around 25°C).
Once opened, it’s best to keep the milk in the fridge and consume it within 5 days.
Thanks so much for the suggestion!

Naturlean products fall into two categories: unsweetened and sweetened with date sugar.
Nuts naturally contain small amounts of natural sugars like fructose and glucose, which develop during growth.
That’s why even our unsweetened products may have a mild natural sweetness.
Naturlean plant milks are made by blending nuts with water, filtering the mixture, and then applying UHT processing at 140°C for about 4 seconds.
They’re then packed in aseptic packaging to extend shelf life without preservatives.
The heat doesn’t affect nutritional quality—it simply removes harmful microorganisms and keeps the product safe and fresh.
Naturlean plant milks are suitable for all age groups.
They’re lactose-free, cholesterol-free, and gluten-free—making them a great option for people with allergies, lactose intolerance, or specific dietary preferences.
Yes, Naturlean plant milks are suitable for people with celiac disease, as they’re free from gluten and lactose.
As always, it’s best to consult your doctor before adding any new product to your diet.
UHT stands for Ultra High Temperature processing.
In this method, the liquid (like plant-based milk) is heated briefly to about 135–150°C for 2–5 seconds, then rapidly cooled.
This process:
Eliminates harmful bacteria
Preserves vitamins, flavor, and nutritional value
Allows long shelf life at room temperature (before opening)
Works perfectly for plant milks like almond, hazelnut, and oat
All without adding preservatives or chemicals 🌿
