Milk and plain yoghurt are familiar sources of calcium, but a Singapore grocery basket can also include calcium-fortified soy drink, tofu made with calcium salts and canned sardines with edible bones. If you are replacing dairy, check the calcium number on the specific food or drink you plan to buy. Two soy drinks can look similar and supply very different amounts.
Calcium helps maintain bones and teeth. It is particularly relevant when children and teenagers are growing and as adults get older. Start with a food your household already enjoys and check its contribution in the amount you normally eat. You can then decide what makes sense to add at another meal.
- Look for fortified soy drinks, calcium-set tofu and fish with edible bones if you eat little or no dairy.
- Check milligrams of calcium per 100 mL or 100 g when comparing similar products.
- Calculate the amount in the glass, bowl or portion you actually have.
- Use age-appropriate guidance when planning meals for children and teens.

Where to find calcium in everyday meals
Calcium can come from several parts of a meal. At breakfast it may be milk or plain yoghurt. At lunch it might come from tofu made with calcium salts, and at dinner it could come from sardines if you eat the soft bones. Green vegetables such as kai lan and bok choy can contribute, too. A varied approach gives you more choices when a product is unavailable. HealthHub’s guide to calcium and bone strength
| Food | What to check | Where it fits |
|---|---|---|
| Milk or plain yoghurt | Calcium per 100 mL or 100 g and the usual serving | Oats, breakfast bowls or a snack |
| Fortified soy drink | Whether calcium was added and the amount on the panel | In a glass, with oats or in a smoothie |
| Tofu | Whether calcium salts are used and whether the calcium figure is declared | Soup, a braise or a rice bowl |
| Sardines with edible bones | Whether bones are included and eaten | A sandwich, rice bowl or pasta |
| Ikan bilis | Portion size and sodium, particularly in salted products | A small part of a meal |
| Leafy green vegetables | The kind of vegetable and the amount you will eat | Stir-fries, soups or a vegetable side |
A food can contribute calcium without providing most of what you need. A spoonful of ikan bilis is usually a much smaller portion than a glass of milk or fortified soy drink. Think about how often you eat the food, the actual amount and what else is in the meal.
Section 2 of 5 · Read the label before deciding
Compare soy drinks, tofu and milk at the shop
Start with the calcium line. If both drinks list calcium per 100 mL, compare those figures first. If they list it per serving, check how big each serving is. Then consider protein, added sugar where information is available, cost and whether you will use the carton before it spoils. For a product you plan to use frequently in place of milk, the amount of calcium on the label matters more than the colour or shape of the carton. HealthHub’s guide to reading food labels
Work out what is in your glass
Suppose an illustrative fortified soy drink lists 120 mg of calcium per 100 mL. A 200 mL glass provides 240 mg, and a 250 mL glass provides 300 mg. These are worked examples, so use the numbers on your own carton. If a second drink lists 180 mg per 250 mL, that works out to 72 mg per 100 mL. The equal-volume comparison is 120 mg against 72 mg.
Check how the tofu was made
Tofu made with calcium salts can supply calcium. Check the ingredients for a calcium-based coagulant such as calcium sulphate and look for the calcium amount if one is declared. Firmness tells you about texture and cooking behaviour. A firm block may be calcium-set, but firmness alone cannot tell you how much calcium it contains. At a stall, an exact milligram figure may be unavailable, so use a labelled source elsewhere if you need to track intake closely.
When a drink says “plant-based”
Oat, almond, rice and soy drinks vary widely. Check the nutrition panel and ingredients before treating a new drink as a regular replacement. If the label asks you to shake the carton, follow that instruction before pouring. For children with allergies or medical dietary needs, a clinician or dietitian can help choose a suitable substitute.

Build a day with or without dairy
If you eat dairy
Try oats made with milk at breakfast, cai fan with a vegetable dish at lunch and a tofu or fish dish at dinner. Plain yoghurt with fruit can be an alternative when the morning meal is savoury. Start with foods you enjoy and choose portions that fit your appetite.
If you prefer a dairy-free routine
Try oats with a calcium-fortified soy drink, a tofu and greens lunch, and sardines with edible bones at dinner if you eat fish. If your household eats fully plant-based, use labelled fortified options and calcium-set tofu where available. A naturally dairy-free drink may still contain very little calcium unless it has been fortified.
If different people share the same kitchen
Agree on one shared meal and let each person use a suitable option on the side. A breakfast of toast, cooked egg and fruit can go with milk for one person and a fortified soy drink for another. Plan the portions by what each person eats, and use separate utensils where an allergy requires it. Read the ingredient list every time you change brands or the product changes packaging.

Section 4 of 5 · Understand the daily reference figures
Use age-specific calcium guidance
HealthHub lists 1,000 mg a day for adolescents aged 10 to 18, 800 mg for adults aged 19 to 50, and 1,000 mg for adults aged 51 and above. These figures are reference intakes for those groups. HealthHub provides separate figures for younger children and other life stages. HealthHub’s Singapore recommended dietary allowances
If you want to understand your usual intake, write down two ordinary days before changing anything. Include both drinks and meals. Check the labels on your most-used products, then identify the meal that offers the easiest improvement. A number on a single day is one piece of information. The choices you make across a week show more about your routine.
What vitamin D has to do with it
Vitamin D helps your body absorb calcium. Some foods, including selected fortified products, can contribute vitamin D, but the product needs to say so. Ask a health professional about supplements if you have been advised to limit foods, have an underlying condition or have been told your intake or bone health needs attention.

Calcium questions at the supermarket
Does lactose-free milk still contain calcium?
Lactose-free dairy milk can still supply calcium. Check the label of the product you buy. Lactose-free cow’s milk still contains milk proteins, which matters for anyone with a cow’s milk allergy.
Are boneless sardines the same for calcium?
The soft edible bones are a key source of calcium. Compare the nutrition panels if you are choosing between a boneless product and one with bones.
Does every soy drink have added calcium?
Fortification varies. Look for calcium on the ingredients or nutrition information and compare by the same volume before choosing.
How can I use this with a teenager?
Let them choose one breakfast, drink or dinner ingredient they would use. A carton they like and can finish over the week is more practical than a product that stays in the fridge. If you need ideas for the meal itself, see the school breakfast guide below.
