Calcium is the most abundant mineral in the human body, with approximately 99% stored in our bones and teeth. While dairy products are a well-known source, many people seek alternatives due to lactose intolerance, vegan diets, or personal preferences.
How Much Calcium Do You Need?
Adults typically need 1,000 to 1,200 mg of calcium per day. The recommended intake varies by age and sex, with higher requirements for women over 50 and men over 70.
Non-Dairy Calcium Sources
Several plant-based and fortified foods provide excellent calcium:
- Leafy greens: Kale, bok choy, collard greens, and broccoli are rich in calcium and also provide vitamin K, which supports bone metabolism.
- Fortified foods: Many plant milks, orange juices, and cereals are calcium-fortified.
- Fish with bones: Canned sardines and salmon provide calcium from soft, edible bones.
- Tempeh and tofu: Especially calcium-set tofu, which can contain 400-800mg of calcium per serving.
- Sesame seeds and almonds: Provide calcium along with healthy fats and protein.
Maximizing Calcium Absorption
Getting enough calcium is only half the battle — your body also needs to absorb it efficiently. Vitamin D is essential for calcium absorption. Limit excessive caffeine and sodium, as high intake of both can increase calcium excretion through urine.
Spreading calcium intake throughout the day, rather than consuming it all in one meal, can also improve absorption.
