7 Tips to Increase Calcium Absorption

Published on 18 March 2012 by in Blog


Seven tips to increase your calcium absorption:

  1. Get sufficient vitamin D from sun light
  2. Eat calcium-, magnesium-, chlorophyll-, and mineral-rich foods, especially grains, legumes, leafy greens (including cereal grasses and micro-algae), and seaweeds.
  3. Avoid calcium inhibitors (chocolate, coffee, alcohol, sugar and excess consumption of any sweetener (e.g. honey, rice syrup, etc.), excess meat consumption)
  4. Exercise regularly and moderately to halt calcium loss and increase bone mass.
  5. Presoak grains, legumes, nuts and seeds before cooking/consumption to neutralize their phytic acid content, which otherwise binds the calcium, zinc, iron and other minerals in these foods.
  6. Use oxalic acid foods sparingly – rhubarb, cranberries, plums, spinach, chard and beet greens
  7. If dairy is used, they fermented forms are easier to digest – kefir, etc.

Calcium is not only an important mineral that is essential to strengthen and build our bones.

Calcium also

  • calms the nerves
  • relaxes the liver and
  • benefits the heart.

Absorption and Utilization of Calcium

When we want to improve our calcium status to maintain a healthy bone mass it is not only crucial to eat calcium rich foods. We need to make sure that we absorb and utilize the calcium from foods effectively. As all the minerals in the body are in a delicate and dynamic balance, an improvement in calcium absorption will also improve the effective use of other minerals in the body. Calcium absorption requires adequate dietary magnesium, phosphorus, vitamin A, C and D. Without certain of those nutrients, it appears that calcium can not be absorbed at all.

Dairy Foods as the Synonymous for Calcium

Calcium in our diet is perceived as almost synonymous to the use of dairy products. However, dairy foods are generally not of good quality and this is perhaps one of the main reasons that so many people in the Western World, who consume large amounts of dairy (25% of the average diet), still have widespread calcium deficiency problems such as osteoporosis and arthritis. In China and areas of Southeast Asia where diary consumption is minimal, arthritis and bone deteriorations are not the major health problems as they are in the wealthier countries.

    Thank you for this article Verena. This is very helpful information for my brittle bones. Hannah

  2. Diana says:

    I was told that if I need calcium and must take supplements, I should avoid carbonated beverages at all costs. I LOVE my sodas–any chance that the carbonation DOESN’T cancel out the calcium I’m taking? I’m really HOPING…..

    Thank you.

  3. I seldom leave comments on blogs, but you really impress me, also I have a few questions like to ask, what’s your contact details?


  4. Verena says:

    Dear Johnson,
    Thank you for your nice feedback. You can contact me at verena@drverena.com. Best regards. Dr Verena

  5. Rick Isabelle says:

    You mention leafy greens as a good thing but – while searching the net I found the following: “Spinach also has a high calcium content. However, the oxalate content in spinach also binds with calcium, decreasing its absorption. Calcium and zinc also limit iron absorption.[16] The calcium in spinach is the least bioavailable of calcium sources.[17] By way of comparison, the body can absorb about half of the calcium present in broccoli, yet only around 5% of the calcium in spinach.

    Your thoughts?

  7. In 7 Tips to Increase Calcium Absorption, you surprised me by saying that dairy is not a high quality source of calcium. What are the ideal foods and food combinations you recommend. I have osteopena, am physically active, take Actonel, and will take whatever’s best for me. Please advise.

    Milk has only 119 edible portions Calcium (Ca) in mg compared to Hijiki or Wakame that have 1400 mg or 1300 mg, respectively. They are sea vegetables and you can purchase them in any health food store. I also recommend garnishing your meals with Kelp (1099 mg Ca). Barley grass or wheat grass are also high in Calcium as well as Nori, almonds, Amaranth, Hazelnuts, Parsley, Brazil nuts, Sunflower seeds, Watercress, Quinoa, Kale, Spirulina. Those foods all contains the calcium co-factors that are necessary for its absorption. Dr Verena

  17. Lawrence says:

    I eat a good diet and take all kinds of calcium supplements to maximize absorption; however, I have severe osteoporosis and my muscles have become painful with little activity. I added CHIA Seed to my diet and it made all the difference in the world. My back muscles relax quickly and I feel no pain in my back. A tablespoon of CHIA seed in a cup of water 3 to 4 times a day gets me through my day. I have been using CHIA seed for 6 months now and I am looking for many more happy days.

    Tucked in the Blue Mountains northwest of La Grande is a relatively new trail system developed and groomed by the Blue Mountain Nordic Club, a chapter of the Oregon Nordic Club. The trails mostly follow forest roads, but have a fine mix of challenging hills, rolling terrain, and flat stretches. On clear days there are excellent views of steep canyons and the northern Blues.

    When she received back, she dropped me considering she attained a person else while she was absent. The first shock was equivalent for the first time, but overall, it had been substantially worse, partly as there had been a whole lot of other upheavals in my daily life at the time and it had been the last straw. It took me years to get better (I didn have one more proper connection for about four years)..

    The primary difference amongst love-making as being an addiction along with as a philanderer will be the compulsiveness of your habits. A new sexual intercourse lover can take part in erotic actions using anybody that would like to engage in a intimate behaviour involving his or her alternative.
