Buy Adcal-D3 Lemon Chewable Tablets

Adcal-D3 Lemon tablets contain 1500mg of calcium and 400IU of vitamin D3, helping to top up your levels to support healthy bones and teeth. You can buy it over-the-counter, without needing a prescription.

As a chewable tablet, it's a convenient option if you struggle to swallow tablets or capsules whole.

What are Adcal-D3 tablets used for?

Adcal-D3 tablets are used for the prevention and treatment of a calcium or vitamin D deficiency. For example, you might not be getting enough from your diet or during the winter months when there isn't as much sunlight. Doctors may prescribe it for certain bone conditions, too, including osteoporosis.

It’s best to take vitamin D3 and calcium together because vitamin D3 is essential for your body to absorb and use calcium effectively.

How to take Adcal-D3 tablets

Adults, the elderly, and children over 12 years old should take two tablets a day, ideally one in the morning and one in the evening. Chew the tablets - don't swallow them whole.

If you forget a dose, just take it as soon as you remember, then carry on as normal. Don't double up to make up for a missed tablet.

Try not to take this supplement within two hours of eating foods high in the following, as these can affect how well it's absorbed:

• oxalic acid, like spinach or rhubarb
• phosphate, like bran
• phytic acid, like whole cereals

When to avoid Adcal-D3 tablets

Don't take this supplement if you:

• are under 12 years old
• are allergic to calcium carbonate, vitamin D3, or any of the other ingredients
• are allergic to peanut or soya, as this medicine contains soya oil
• have high calcium levels (hypercalcaemia) or high calcium in urine (hypercalciuria)

Can you take other medicines with Adcal-D3 tablets?

Let your doctor or prescriber know if you're taking:

• other calcium supplements or antacids for indigestion

Leave a gap of at least four hours between taking these and taking Adcal-D3. Don't take them at the same time.
