Strontium Food Sources
Strontium isn’t well-known for its abundant food sources. And with good reason.
As a trace mineral, it’s not found in overwhelmingly large quantities, but it is there. And because strontium is typically found in calcium-rich foods, it’s often overlooked for its more high profile sister-mineral.
But if you don’t have enough strontium in your diet, all the calcium in the world won’t help you increase bone density.
How to Get Enough Strontium For Optimal Bone Health
Strontium is found in natural water sources like oceans and rivers, as well as in plants, soil, and even rocks. From those sources, it works its way into the things we eat and drink.
Cereals, grains, and seafood have the highest amounts of strontium. But having said that, these sources still only contain trace amounts. The volume of strontium in vegetables and fruit depends on the soil they grow in, which is why it’s difficult (and often inaccurate) to estimate how much is in any given piece of produce.
To confuse the matter further, commercially-produced plant foods grown on fields using synthetic fertilizers, pesticides, and herbicides have far lower levels of strontium than their organic counterparts.
Generally speaking, plants are a better source of strontium than animal products. Unless the animal source contains bone. The bran of grains, the peel of root vegetables, spinach, lettuce, carrots, peas, and beans all contain relatively high levels.
Brazil nuts are also a hearty source of natural strontium. When it comes to seafood as a strontium source, look for filter-feeding shellfish like oysters and scallops.
Dairy products like milk and cheese are a good source of natural strontium too. Lower fat products tend to have more strontium than their full-fat alternatives. If you’re hoping to get a good dose of strontium with your morning coffee, opt for whole milk over cream. Cream has roughly half the amount of strontium as whole milk. In fact, skim milk and cheddar cheese are two of the best dairy-based strontium sources.
But is that enough?
The amount of strontium found in food sources is simply too low to make an impact on bone health on its own.
In Europe and North America, the typical dietary intake of strontium hovers around 2–4 mg/day.
Which is a far cry from the optimal daily intake. Most studies looking at strontium for bone health used 340–680 mg of strontium per day to see benefits. That’s a huge difference!
So what can we do?
Well, we can top up our strontium levels with a natural strontium supplement.
Strontium comes in a variety of forms, but the most common supplemental form is strontium citrate, which is found in AlgaeCal’s Strontium Boost. Other natural forms include strontium carbonate, lactate, and gluconate.
Strontium Boost is pure, clinical grade strontium citrate. Each two-capsule serving contains 680 mg (inline with study recommendations) of bone supporting strontium. It’s also backed by research and two human clinical trials ー ensuring its safety and effectiveness.
In fact, after seeing an average bone density increase of 2% during the six-month study, the Strontium Boost and AlgaeCal Plus combination (known together as the Bone Builder Pack) was put to the test again for a seven-year study. Researchers discovered that the addition of strontium continued to have a positive impact on bone density gains. The postmenopausal participants gained an average of 7.3% bone density over seven years.
Calcium and strontium (the key minerals in the Bone Builder Pack) are both absorbed in the gut. So they compete with one another for absorption. So it’s important to take the supplements separately. By staggering your intake, you allow both supplements to be absorbed properly and effectively.
You should take strontium on an empty stomach. Ideally an hour before, or three hours after eating. Calcium, however, should be taken with a meal as food increases its absorption rates.
