Natren UK & Europe Chilled Delivery

Do Your Probiotics Survive Shipping, Storage and Stomach Acid?

We talk a lot about what’s in Natren Probiotics (carefully selected super strains of beneficial bacteria) and what’s not in our Natren Probiotics (No GMO’s, No FOS, Soy Free, Gluten Free, Dairy Free Options, etc) but today we want to talk about how we handle our products and why that’s unique.

Probiotics are living bacteria, and like most bacteria, they can be severely weakened or killed by prolonged exposure to moisture or heat. That’s a big problem, because although Natren take every step necessary to ensure that the probiotics are kept at the optimum temperature and humidity during production and storage at their pharmaceutical grade manufacturing facility in Westlake Village, California, once they leave the premises the journey can be quite harsh. Here is a behind the scenes look at how we ensure that your probiotics reach you in the condition they need to – alive, well, and ready to go to work! And we are so confident about this process that we offer a 100% potency guarantee of each probiotic strain through the printed expiration date!

Manufacturing & Packaging

Natren probiotics are manufactured and stored in a temperature and humidity-controlled environment at the headquarters. We do our best to keep them in that state all the way to your doorstep. The key to this is high quality packaging – and that takes more than just a regular box!

The vital feature to shipping Natren probiotics cold is ice – and lots of it. This is no ordinary ice though – we use commercial grade gel ice packs. All of this is contained inside a polystyrene layer within the cardboard outer box, which insulates the contents against the outside environment. The products are then air-shipped direct to Natren UK  refrigerated storage facility in East Sussex. Once your order is received by Natren UK the products are individually bubble wrapped – not only for insulation – but also to act as a moisture and freeze barrier between the probiotics and the ice. We surround each individual bottle with it’s own gel ice packs and then place in a special thermal controlled box. Any space left is filled with biodegradable packing peanuts to avoid breakages in transit.


To ensure you receive your products alive, well, and ready to go to work, no matter where you are in the UK or Europe, we use  thermal insulated packing. This packaging has been carefully chosen specially for Natren Probiotics due to the robust internal material which reflects up to 97% of heat transferred via radiation (sun, heat) and reflects up to 97% of the cold air back into the product and its surrounding space, maintaining products colder for longer.

Please note: gel ice packs will melt during transit, this is not a refrigerated service but will keep the products in good condition.


Natren Healthy Trinity


The bottle itself is designed to protect the probiotics inside. The dark amber glass bottles offer protection from light and moisture, we believe glass offers much more superior protection from moisture than plastic bottles that may allow moisture and gases to seep in over time. The metal lid is also designed to prevent damage from moisture, and the plastic shrink-wrap adds an additional layer of protection for the glass bottle, and also serves as a safety seal to the consumer that the product is intact and has not been tampered with. These glass bottles are also eco-friendly and recyclable.


From Cell to Shelf – We Care Through The Whole Process

By going the extra mile with our shipping & packaging, we deliver a probiotic that we are confident to guarantee as fully potent through the expiration date. We also ensure similar high standards for our products purchased at retail stores – our probiotics are cold-shipped to the store, and the store is required to move them into cold storage within 4 hours. This way, you can be assured that however you buy your Natren Probiotics, they get to you alive, well and ready to go to work!
