Vitamin D3 (cholecalciferol) is a fat‑soluble vitamin that helps the body maintain normal bones, teeth and muscle function, and supports the normal function of the immune system when intake is sufficient. In this product, vitamin D3 is provided in a high‑strength 4000 IU dose per spray, suitable for short‑term or targeted use when recommended by a healthcare professional. The oral spray format distributes fine droplets onto the inside of the cheek, offering an alternative to traditional tablets and allowing you to take vitamin D3 without water, wherever you are.
Each spray provides 4000 IU (100 µg) vitamin D3, allowing you to reach a higher daily intake in a single, clearly measured action. This strength is typically used when an increased intake has been advised, for example in adults with limited sun exposure or specific requirements, and should always be used in line with label instructions and professional guidance. The label clearly states the amount of vitamin D3 per spray and the total number of doses in the bottle.
The Osavi spray uses a fine‑mist pump that applies vitamin D3 directly into the mouth, usually onto the inner cheek. This route provides a practical alternative for people who dislike or have difficulty swallowing tablets or capsules. It also makes it simple to take vitamin D3 at home, at work or while travelling, without needing water or food at the same time.
The 12.5 ml bottle is compact and travel‑friendly while still providing up to 125 sprays, offering roughly four months’ supply at one spray per day. The small size fits easily into a pocket, bag or bathroom cabinet, so you can keep it to hand and maintain a regular routine. A protective cap helps keep the nozzle clean between uses.
Always refer to the product packaging for the most accurate, up‑to‑date information.
Vitamin D supplements are widely referenced in UK public health advice, particularly for autumn and winter months or for people with limited sun exposure. High‑strength sprays such as Vitamin D3 Max 4000 IU are typically intended for adults who have been advised to use a higher daily dose for a defined period, or whose lifestyle, clothing, skin coverage or diet may reduce vitamin D synthesis and intake. This product is designed to be used alongside, not instead of, a varied diet and healthy lifestyle.
Shake the bottle, then apply the directed number of sprays inside the cheek once per day and swallow normally. You do not need water to take it.
Because this is a high‑strength vitamin D3 product, long‑term use should be guided by a healthcare professional, particularly if you also obtain vitamin D from other supplements or fortified foods.
Vitamin D3 is often taken alongside other nutrients, but you should consider your total vitamin D intake from all sources. If in doubt, speak to a healthcare professional before combining multiple products.
Check the label for information on the source of vitamin D3 and any dietary symbols confirming suitability for vegetarians or vegans.
