Want to stock up on iHerb vitamins? What you need to know and why it matters now

The American marketplace iHerb operates with full transparency: you can see the expiration date of a specific warehouse batch before you even add the item to your cart.

• The line in the product details: below the product name there is an expiration date field, labeled in English as Best By.
• You can safely buy a year's supply: if the website shows 07/2030, you're guaranteed to receive a batch with several years of shelf life remaining, and the 2–3 week transit across the ocean won't turn your order into expired goods.

Check the Serving Size: a label that says 120 Capsules on the bottle does not mean 120 days of use. If the instructions say to take 2 capsules twice a day (4 per day), that bottle will last exactly 30 days. Accordingly, if you're buying for several family members, you can multiply the number of bottles by the number of people and the length of the course — for example, a preventive course of vitamin D3 typically lasts 3–6 months.

We offer a special rate for iHerb: $9.99 up to 1 kg and $29.90 up to 3 kg. The special price is valid until January 31, 2027, and is available for both self-purchases and purchases through a buyer — with delivery to a parcel locker or pickup point under the Superfast or Fastbox rates.

• When building your cart, you can always see the weight of the items being sent to you. To stay within the weight limits for parcels eligible for the promotion, leave room for packaging when you shop: if you're ordering a parcel up to 1 kg, allow approximately 200–250 grams; for up to 3 kg, allow approximately 300–350 grams.
• The free buyout service is a great deal: if you don't have a US card, a Prostobox operator will place the order for you. With promo code GETIHERB the buyout service is free — you only pay for the supplements themselves and shipping.
• One parcel can contain up to 20 items (with no more than 3 identical items and 4 of the same type).
• If you want to send a large number of similar items, we recommend placing orders on behalf of your family members, friends, or colleagues — you can add as many recipients as you like in your account and pay for their orders and shipping with your own card.
• The duty-free limit is €200 per parcel. If the value of your items exceeds this, we recommend splitting them into multiple parcels — and it's best to do this at the time of purchase, meaning placing separate orders on our website and paying for them separately on iherb.com.
• An added convenience of our service — when placing an order, you can send just a single link to your entire iHerb cart, and all declarations are filled in for you by an AI assistant. There's no need to enter the link, name, price, and quantity for each product individually — our built-in neural network does it all in seconds!

As long as a bottle is sealed by the manufacturer, the product is guaranteed to retain its properties for the entire shelf life. At home, it's enough to follow a few basic rules.

• Don't remove the protective seal in advance: the factory seal hermetically protects the capsules from moisture and oxygen. Only open the next bottle once the current one is finished.
• Leave the desiccant inside opened bottles: the silica gel packet protects the capsules from humidity every time you open the lid during a course.
• A dark, dry place: room temperature (up to 22–24 °C) and a closed shelf in a living area are ideal. A bathroom or cabinets near a kitchen stove are fine for vitamins you take daily, but are not recommended for long-term storage due to sharp temperature fluctuations and steam.
