Vitamin D3 4000 iu - 400 High Strength Easy to Swallow Premium Softgels - Over A Year's Supply - Max Strength Vitamin D3 Cholecalciferol Supplement

9.7 Exceptional

Main highlights

✔ WHY IS NUTRAVITA VITAMIN D3 4000 IU GREAT VALUE FOR MONEY? – Our Maximum Strength Full-Year Supply soft gel capsules with an extra month FREE are especially formulated to aid in normal maintenance of our bones, teeth, muscles and immune system even without the sun (claims substantiated by EFSA – European Food Safety Authority). Taken only once a day, our Vitamin D3 4000 IU comes in small, easy-to-swallow soft gel capsules, not tablets and does not contain bulking or anti-caking agents.
✔ HOW IMPORTANT IS VITAMIN D? – Getting enough Vitamin D is essential for our health as scientific studies indicate that it plays an important role in the process of cell division, in normal absorption of calcium and phosphorus, and in maintaining normal blood calcium levels for healthy bones and teeth (claims are backed up by EFSA). The Vitamin D ingredient in our supplement is sourced from Germany.
✔ WHY DO WE NEED TO TAKE VITAMIN D SUPPLEMENTS? – Vitamin D is produced naturally by the body in response to sunlight and found in certain dietary sources such as oily fish, mushrooms and eggs. However, since it can be difficult to meet the required daily allowance from sunlight and food alone, taking supplements can help maintain satisfactory Vitamin D levels throughout the year.
✔︎ QUALITY TESTED – Unlike many supplements, we haven’t spared any expense on quality. Each ingredient is quality tested before the manufacturing process begins, every batch of our supplement undergoes further rigorous quality testing. We have done our best to provide as much information as possible, but if you do have any questions please reach out to our very helpful customer care team. They will be happy to provide personalised assistance to help this supplement fit into your lifestyle.
✔ WHAT IS THE STORY BEHIND NUTRAVITA? – Nutravita is a recognised and trusted Vitamins & Supplements brand providing thousands of customers across the world since 2014. Our high quality products are manufactured, batch tested and certified in the UK, and safeguarded by the highest manufacturing standards in the world (GMP, BRC).
