Most mornings you can find me in the kitchen, usually in my slippers, concocting another strange yet interesting potion in the hopes of confounding my husband understanding more about natural health! Not the pill kind of health, or the spend-every-dime-you-make on expensive artificial supplements kind of health, but the real and true wholesome recipes that our great grandmothers used.


Whole food and herbal vitamins and supplements are really making a comeback right now, and for good reason. Research is showing us that synthetic vitamins are doing little to help our bodies. Some of them are even proving to raise our risks for disease. Not good, right? 

Calcium Supplements Side Effects

One of the biggest issues with synthetic calcium supplements is how little of them we are able to absorb. The bottle may say that you are taking a 600mg pill, but our bodies have a funny way of avoiding the fake stuff in favor of the real thing. That's not to say that all synthetic supplements are useless or harmful, of course. But in this case, calcium tablets are one of them. Studies are beginning to show that artificial calcium tablets may be leading to an increase in breast cancer and heart attacks.1

According to this study, whole food sources of calcium are absorbed in much higher quantities than tablets you can buy at the store. On top of that, it turns out that you actually need less calcium overall when getting it from natural sources.2

So how can I get more calcium from food sources? 

Glad you asked! Let's take a look at this list of calcium rich foods...

  • Homemade bone broth- used to make soups, gravy, and casseroles
  • Raw, unpasteurized dairy
  • Leafy green vegetables (organically grown)
  • Eggshells from pasture-raised chicken or duck eggs

One of the most important things to keep in mind when you plan to supplement is that vitamins and minerals work in synergy with other specific vitamins and minerals. For example, zinc and copper are two peas in a pod. If you supplement with one, you really need to supplement with the other as well! Taking large amounts of a certain vitamin or mineral without doing the same for it's counterparts can cause deficiencies, and that's never a good thing. 

Calcium Properties and Counterparts

One thing we now know about calcium is that it works in synergy with magnesium, Vitamin D, and Vitamin K2. It is crucial that you take all four together to keep your vitamin levels rising in tandem- and to prevent deficiencies. 

I'll let you in on a little secret- working these into your daily diet isn't hard! Magnesium can be found in most types of seaweed. I know, I know, most of us don't eat a whole lot of seaweed. But! (You're not off the hook yet.) 

Pastured eggs and bone broth are great sources of natural calcium, Vitamin K2, and contain some Vitamin D. Add a couple of strips of dry seaweed to your broth pot, and you've got an all in one superfood. Did I mention that the natural gelatin in broth prevents wrinkles, gives you beautiful skin, and prevents stretch marks?

I'm talking to you, ladies- bone broth is the best source of gelatin and collagen you can get. Forget botox and laser therapy. Your diet and lifestyle is the number one way to stay beautiful and young.

I like to eat the broth for breakfast, use it as a base for chili and chowder, and add wide rice noodles and pastured eggs for a delicious egg drop soup.

According to Dr. Kate Rheaume-Bleu,

"When you take vitamin D, your body creates more of these vitamin K2-dependent proteins, the proteins that will move the calcium around. They have a lot of potential health benefits. But until the K2 comes in to activate those proteins, those benefits aren't realized. So, really, if you're taking vitamin D, you're creating an increased demand for K2. And vitamin D and K2 work together to strengthen your bones and improve your heart health.

... For so long, we've been told to take calcium for osteoporosis... and vitamin D, which we know is helpful. But then, more studies are coming out showing that increased calcium intake is causing more heart attacks and strokes. That created a lot of confusion around whether calcium is safe or not. But that's the wrong question to be asking, because we'll never properly understand the health benefits of calcium or vitamin D, unless we take into consideration K2. That's what keeps the calcium in its right place."

5. Place the pieces in the glass jar, and cover with vinegar. Leave about an inch of head space to leave room for the foam. Put the lid on loosely to allow air to escape for the first hour, then tighten it down.

6. Shake your jar daily. Once the eggshell has disintegrated, your calcium tincture is ready! (This takes about 6-10 days.) No need to refrigerate.

7. Take one tablespoon daily as a natural calcium supplement.
