I think they are excellent value for money and I am pleased with my choice of Vitamin D and I will continue to take them one per day until they are finished Thank you ### ⭐⭐⭐⭐⭐ Easy to take. *by A***I on 4 November 2025* Excellent product. As a family we take vitamin D everyday. Very important through the dark winter months. When there is no natural vitamin D. ### ⭐⭐⭐⭐ The maximum recommended dose in the UK *by G***D on 30 January 2023* These are excellent value for very high dose Vitamin D tablets - previously I was buying tablets that were a quarter of this strength. Below I've pasted extracts from the NHS website, which makes the points that you should only really need these supplements in the dark Winter months, and that for some people the dosage of these will be too high. In fact we've tried cutting these to take half the dosage, but using an NHS-supplied pill-cutting-thingy the tablets crumble rather than split evenly, so I may go back to my old pills (purchased from Home Bargains!) THIS IS WHAT THE NHS SAY ABOUT VITAMIN D SUPPLEMENTS... Between late March/early April to the end of September, most people can make all the vitamin D they need through sunlight on their skin and from a balanced diet. Taking too many vitamin D supplements over a long period of time can cause too much calcium to build up in the body (hypercalcaemia). This can weaken the bones and damage the kidneys and the heart. If you choose to take vitamin D supplements, 10 micrograms a day will be enough for most people. Do not take more than 100 micrograms (4,000 IU) of vitamin D a day as it could be harmful. This applies to adults, including pregnant and breastfeeding women and the elderly, and children aged 11 to 17 years. Children aged 1 to 10 years should not have more than 50 micrograms (2,000 IU) a day. Infants under 12 months should not have more than 25 micrograms (1,000 IU) a day. Some people have medical conditions that mean they may not be able to safely take as much. If in doubt, you should consult your doctor. ## Frequently Bought Together - Vitamin D 4000IU 365 Vegetarian Tablets | High Strength Cholecalciferol Vitamin D3 Supplement | UK Manufactured - Vitamin B Complex 365 Tablets - with B1, B2, B3, B5, B6, B12, Biotin, Folic Acid - UK Manufactured --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/155467041-vitamin-d3-4000-iu-high-strength-400-vegetarian-tablets-vitamin](https://www.desertcart.tn/products/155467041-vitamin-d3-4000-iu-high-strength-400-vegetarian-tablets-vitamin) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-10*
