Taking Joint Assurance alongside Vitamin D3 1000 may lead to you consuming more Vitamin D than you realise. Joint Assurance often contains Vitamin D as part of its 'bone health' formula. While Vitamin D is essential, taking too much over a long period can lead to high calcium levels in your blood.

Why this happens
Both products contain Vitamin D (Cholecalciferol). This is an additive interaction where the total daily dose is the sum of the Vitamin D in the Joint Assurance supplement plus the 1000 IU from your separate Vitamin D3 tablet.
What you should do
Check the 'Nutritional Information' label on your Joint Assurance bottle. If it already contains 1000 IU (25mcg) or more of Vitamin D, you likely do not need the extra supplement unless specifically told to take it by your doctor. If the Joint Assurance contains a small amount (e.g., 200-400 IU), taking both is generally safe for most adults. If you are unsure of the total dose, ask a pharmacist to check the labels for you.
