Calcium and Vitamin D: The Perfect Partnership

Calcium and vitamin D work together.

Vitamin D helps your body absorb and use calcium effectively. Without enough vitamin D, your body cannot utilise calcium as efficiently, regardless of how much calcium you consume.

Good sources of vitamin D include:

• Safe sunlight exposure
• Oily fish such as salmon and mackerel
• Fortified foods
• Vitamin D supplements when recommended

For healthy bones, it is important to ensure you are getting adequate amounts of both nutrients.

Do You Need a Calcium Supplement?

Most people can meet their calcium requirements through food alone. However, supplements may be helpful if you:

• Avoid dairy products
• Follow a vegan diet
• Have lactose intolerance
• Have digestive conditions that affect absorption
• Have osteoporosis or are at high risk of bone loss
• Struggle to get enough calcium from food

The two most common forms are:

Calcium Carbonate

• Contains a higher percentage of calcium
• Best taken with food
• Widely available

Calcium Citrate

• Absorbed well with or without food
• Often easier on digestion
• May be preferable for people with stomach sensitivity

Always follow the recommended dose and seek advice from a healthcare professional before starting supplements.

Can You Have Too Much Calcium?

Yes. More calcium is not always better.

Taking excessive amounts of calcium, particularly through supplements, may cause:

• Stomach pain
• Constipation
• Diarrhoea
• Nausea
• Kidney stones

The NHS advises that taking more than 1,500mg of calcium daily from supplements may be harmful.

Remember that many multivitamins and combination supplements also contain calcium, so check labels carefully.

Practical Tips to Maintain Healthy Calcium Levels

Keeping your calcium intake consistent can be easier than you think.

Spread Calcium Throughout the Day

Your body absorbs calcium more efficiently in smaller amounts rather than very large doses at once.

Include Calcium at Every Meal

Simple ideas include:

• Yoghurt with breakfast
• Cheese with lunch
• Kale or broccoli with dinner
• Fortified plant milk in tea, coffee or cereals

Check Fortified Products

Plant-based alternatives can vary greatly in calcium content.

Don't Forget Vitamin D

Calcium relies on vitamin D for absorption, so ensure you're getting enough of both.

Stay Active

Weight-bearing exercise such as walking, dancing and strength training helps maintain strong bones.

Signs You May Not Be Getting Enough Calcium

A mild calcium deficiency may not cause obvious symptoms at first.

However, ongoing low calcium intake may contribute to:

• Muscle cramps or spasms
• Tingling sensations
• Brittle nails
• Fatigue
• Reduced bone density
• Increased fracture risk

If you are concerned about your calcium intake or symptoms, seek advice from your GP or healthcare professional.

What the NHS Says About Calcium

The NHS advises that most adults should be able to obtain all the calcium they need through a varied and balanced diet.

Key NHS recommendations include:

• Adults generally need 700mg of calcium daily
• Dairy products are excellent calcium sources
• Leafy green vegetables and fortified foods can help boost intake
• Fish with edible bones provide significant amounts of calcium
• Avoid taking excessive calcium supplements
• Taking more than 1,500mg a day from supplements may be harmful
• A balanced diet should be the primary source of calcium whenever possible
