Why vitamin D deserves attention
In autumn and winter, UK sunlight is not strong enough for our bodies to make sufficient vitamin D. The NHS advises considering a daily supplement during these months.
4,000 IU: choosing the right strength
Two sprays provide 4,000 IU (100µg) of vitamin D3, one daily serving as described in the product directions. The right dose depends on your individual needs and any clinical advice following your results. This strength is not the routine recommended dose for everyone.
Read the NHS guidance ↗Small bottle. Everyday support.
Two vitamins.
One simple routine.
An orange-flavour oral spray combining vitamin D3 with vitamin K2. Two sprays provide 4,000 IU (100µg) of vitamin D3. No tablets to swallow.
01 / IMMUNITY
Support from within
Vitamin D contributes to the normal function of your immune system.
02 / BONES
A strong foundation
Vitamins D and K contribute to the maintenance of normal bones.
03 / MUSCLES
Made for everyday life
Vitamin D contributes to normal muscle function.
The current Kollo spray is high strength: 4,000 IU (100µg) vitamin D3 per two-spray serving. This is above the NHS’s general 10µg autumn/winter recommendation. Check with a healthcare professional that this strength is appropriate for you, particularly if your screening has identified low levels.

A few questions,
answered.
Everything about your welcome bottle, your subscription and your Bluecrest benefit.
Who can claim this offer?
Anyone who books a Bluecrest health assessment by 31 October. You can claim your free bottle after you’ve attended your assessment, so it’s fine if your appointment itself is later.
Is my first bottle really free?
Yes. Your first bottle costs £0 and you pay £3.99 postage. Taking this offer also starts a subscription: £34.18 in 28 days for three bottles, then £34.18 every 3 months (every 84 days). Across your first two deliveries that’s 4 bottles for £38.17, usually £75.96 bought one at a time. Cancel, pause or skip anytime.
When will I be charged?
Today you pay £3.99 postage for your free welcome bottle. 28 days after your welcome order, your first paid charge of £34.18 is taken for three bottles, a 3-month supply. After that, your subscription renews at £34.18 every 84 days with free UK delivery, unless you cancel, pause or skip. Your 20% lifetime discount is applied automatically to every renewal, taking the usual £42.73 subscription price down to £34.18.
Can I cancel, pause or skip a delivery?
Yes. You can cancel, pause or skip anytime before your next renewal. Cancel to stop future orders, pause your subscription, or skip your next delivery. The final page and order confirmation will include the subscription management link.
How does my 20% lifetime discount work?
On this vitamin D subscription, your 20% discount is applied automatically, so you don’t need a code. It takes the usual £42.73 subscription price down to £34.18 on every renewal. For any other Kollo product, use code BLUECREST20 at checkout to get 20% off that subscription for life. BLUECREST20 is valid on subscription products only.
Does this mean I’m deficient in vitamin D?
No. This is an offer for Bluecrest customers, not a diagnosis. Your individual results and advice from a healthcare professional should guide you. If your results show low vitamin D, ask what dose and follow-up are right for you.
Is this spray suitable for me?
Two sprays provide 4,000 IU (100µg) vitamin D3 and 100µg vitamin K2 per daily serving. Check with a healthcare professional before use if you take medication, are pregnant or breastfeeding, have a medical condition, or already take vitamin D. Vitamin K can interact with anticoagulants such as warfarin. Follow the product label.
