10 Ways to Build Healthy Bones (and Keep Them Strong)

Weak bones may seem like a problem of aging, but there’s plenty we can do early in life (in our teens and 20s) to make sure bones stay healthy down the line

Bones are quite literally the support system of the body, so it’s super important to keep them strong and healthy. Bones are continuously being broken down and rebuilt in tiny amounts. Before about age 30, when bones typically reach peak bone mass (which varies from person to person), the body is creating new bone faster, but after age 30, the bone building balance naturally shifts and more bone is lost than gained.

Some people have a lot of savings in their “bone bank” because of factors including genetics, diet and how much bone they built up as teenagers. The natural depletion of bone doesn’t affect these lucky ducks too drastically. But in those with a smaller bone fortune, when the body can’t create new bone as fast as the old bone is lost, osteoporosis can set in, causing bones to become weak and brittle and allowing them to fracture more easily. The disease is most common in postmenopausal women over the age of 65 and in men over the age of 70.

Although all this talk of menopause and older age makes the threat of osteoporosis seem like a long way off, know that once it sets in, it’s extremely hard to reverse. Since there’s no way of being 100% positive you’ll develop osteoporosis, the best way to counteract it is to take steps earlier in life to beef up bone mass (and prevent its loss) as much as possible.

Unfortunately, some are more likely than others to develop osteoporosis and weak bones in general (namely white and Asian postmenopausal women). Also unfortunately, it’s awfully difficult to change your race, gender or menopausal status. But never fear — there are some things that can be changed to bump up bone mass. Here are 10 tips to make deposits in your bone bank for a healthier future.

1. Know your family history. As with many medical conditions, family history is a key indicator of bone health. Those with a parent or sibling who has or had osteoporosis are more likely to develop it. “So, how’s your bone density, Grandma?” might seem like an awkward question at Thanksgiving dinner, but ask anyway before she passes the gravy.

2. Boost calcium consumption. When most people think bones, they think calcium. This mineral is essential for the proper development of teeth and bones. (Not to mention it’s a huge helper in proper muscle function, nerve signaling, hormone secretion, and blood pressure.)

But calcium isn’t the end-all, be-all bone loss cure. The key might be to help the body absorb calcium by pairing calcium-rich foods with those high in vitamin D. Some studies on postmenopausal women have shown that simply adding calcium alone to the diet doesn’t have a huge affect on bone density (though follow-up studies have suggested the opposite).

Foods that are good sources of calcium include yogurt, cheese, milk, spinach and collard greens. Not a dairy fan? Check out our list of non-dairy sources of calcium.

3. Don’t forget the vitamin D. Where there’s calcium, there must be vitamin D: the two work together to help the body absorb bone-boosting calcium. Boost vitamin D consumption by munching on shrimp, fortified foods like cereal and orange juice, sardines, eggs (in the yolks) and tuna, or opt for a vitamin D supplement. Greatist Expert Eugene Babenko suggests getting your vitamin D (specifically vitamin D3) levels checked at your next doctor’s appointment, and to discuss the use of supplements with your doctor.

The body also produces vitamin D when exposed to the sun — 10 to 15 minutes of exposure three times per week will do. Vitamin D’s importance to bone health has been proven in studies on “seasonal bone loss” — elderly people can lose more bone mass during the winter because of lack of sun exposure. Though these and many other studies on bone loss looked at elderly people specifically, bone health is all about prevention, so younger folks should catch a few rays to stock up on D.

4. Boost bone density with vitamin K. Vitamin K is mostly known for helping out with blood clotting, but it also helps the body make proteins for healthy bones. However, the exact way vitamin K contributes to bone health is unclear. Two studies on young girls showed that vitamin K had different effects: one showed that vitamin K slowed bone turnover, but it didn’t have any effect on bone mineral density, while the other found the reverse.

Another study specifically compared the effects of vitamins K and D on calcium absorption in rats, and it turns out the two vitamins work well as a team: vitamin D stimulated calcium absorption in the intestines, while vitamin K reduced the amount of calcium excreted by the body.

Regardless of how vitamin K might help, fill up on it with foods like kale, broccoli, Swiss chard and spinach.

5. Pump up the potassium. Potassium isn’t necessarily known for aiding bone health: it’s a mineral that helps nerves and muscles communicate and also helps cells remove waste. But it turns out potassium may neutralize acids that remove calcium from the body.

Studies in both pre- and postmenopausal women have shown that a diet high in potassium can improve bone health. In fact, the study involving premenopausal women showed an 8% difference in bone density between women with high potassium intake and those with low potassium intake.

Load up on potassium by eating foods like sweet potatoes, white potatoes (with the skin on), yogurt and bananas.

6. Make exercise a priority. Seriously. Regular exercise is key to keep a number of health issues at bay, and bone health is no exception. In fact, living a sedentary lifestyle is considered a risk factor for osteoporosis. One study comparing bone density in college women with various body weights and activity levels found that athletes with low body weight had the highest bone density of any group in the study, showing exercise (and low body weight) can have a positive effect on bone density.

What type of exercise is most effective? Weight-bearing exercises like running, walking, jumping rope, skiing and stair climbing keep bones strongest. Resistance training has also been shown to improve bone health in several studies, so pick up the weights after going for a jog. Bonus for the older readers: improved strength and balance helps prevent falls (and the associated fractures) in those who already have osteoporosis.

7. Consume less caffeine. Caffeine does have some health benefits, but unfortunately not for our bones. Too much of it can interfere with the body’s ability to absorb calcium. One study showed that drinking more than two cups of coffee per day accelerated bone loss in subjects who also didn’t consume enough calcium. Another study (albeit on elderly women) showed that more than 18 ounces of coffee per day can accelerate bone loss by negatively interacting with vitamin D. So enjoy the java, but keep it in moderation and consume enough calcium, too.

8. Cool it on the booze. But like caffeine, there’s no need to quit entirely. While heavy alcohol consumption can cause bone loss (because it interferes with vitamin D doing its job), moderate consumption (that’s one drink per day for women, two per day for men) is fine — and recent studies actually show it may help slow bone loss. Bottoms up!

9. Quit smoking. Here’s yet another reason to lose the cigarettes: multiple studies have shown that smoking can prevent the body from efficiently absorbing calcium, decreasing bone mass.

10. Don’t be an astronaut. Not to kill any childhood dreams, but because of those hours and hours of weightlessness and low-calcium diets, astronauts often suffer from space-induced osteoporosis. Space-anything sounds kind of awesome, but space bones definitely aren’t: astronauts can lose up to 1% to 2% of their bone mass per month on a mission! For those who simply must visit the moon, there is a possible solution: two studies have found that vitamin K can help build back astronauts’ lost bone — more than calcium and vitamin D.

In other words consistently eat a bit of everything and you'll be fine.


That was interesting to read that family history can have something to do with your bone structure.  The other thing that stuck out to me was all the minerals and vitamins that it mentioned can help your bones.   Making sure you maintain bone density over time is probably something that would be fairly important. http://www.lynchburggynecology.com 


Very interesting post , i agree with 7,8,9 point, i daily smoke, drink and take coffee in daily life and now i am suffering with back-bone pain, i think it's my posture problem then i take posture brace from http://www.bestposturebrace.com/ . now after read your post i got its a calcium problem of my bones..

Thanks really thanks


I would have to disagree with point #2 - increase your calcium intake. Over the past 20 years, peoples' calcium intake has increased over 500%. During this same time period, rates of osteoporosis have increased over 700%. As a nation, we consume the most calcium and have the highest rate of osteoporosis in the world. If all this calcium is so good for our bones, then why the big jump in weak bones, hip fractures, and bone mineral density loss? Plus, it's a grocery fad to add increased calcium to our foods...dairy, cereals, cookies (yes, animal crackers are now considered "an excellent source of calcium"!), juices, and much more. We ingest too much calcium and the wrong kind. Calcium also causes your muscles to contract, including your arterial muscle walls, restricting blood flow. This then gets diagnosed as high blood pressure and more drugs are prescribed. It's magnesium, the most important mineral you can take, that does over 325 things in your body, including making your muscles relax that's needed to counteract too much calcium. Magnesium helps lower blood pressure. Also, over 90% of the calcium added to foods and on drug/grocery/health food store shelves is calcium carbonate - the same stuff contractors pour into cement to make it harder! Calcium carbonate causes arteriosclerosis, kidney stones, and adds to plaque in your arteries. While it's good for bone grafts, calcium carbonate is difficult for your body to absorb. You must take a higher quality calcium like di-calcium malate, coupled with di-magnesium malate, if you want superior bioavailability at lower doses. Due to all the extra calcium in our foods, you should not exceed a 1:1 calcium to magnesium ratio in your supplements, unless advised to do so by a health professional. An ideal dose is 500 mg calcium to 500 mg magnesium. Only 1 out of 4 women over 50 who suffer a hip fracture ever fully recover. Overdosing on calcium has a lot to do with this. Osteoporosis is becoming an epidemic in the U.S.. Twenty-eight percent (28%) of people over 50 who suffer a hip fracture die within 12 months of the break, with 4% dying from the operation and 24% dying from the stress and trauma of the grueling rehab. The odds are stacked against you so why weaken those odds (and your bones) by taking in more calcium?

@RayHolley Maybe osteoporosis rates have increased simply because the elderly population has become much bigger. People are living longer.


It is a true advancement in cancer research. A clinical trial pointed out that they managed to reduce 3-year mortality in people that had metastatic cancers by greater than 5 times. There is nothing comparable to this final result in the entire oncological research. I repeat 5 times fewer individuals deceased in three years once they practiced one particular auxiliary therapy. The therapy was based on the tactic utilised by approximately 200 Russian health care professionals, and the objective of the process is to increase oxygen content in organs implementing the popular Buteyko respiratory method. These breathtaking outcomes are revealed and all specifics of their therapy are outlined in the Kindle eBook from Amazon “Doctors Who Cure Cancer”: <a href="http://www.amazon.com/Doctors-Cure-Cancer-Books-ebook/dp/B007IZZ4AQ/">Cancer cure</a> by Dr. Artour Rakhimov. When you see a person with a cancer tumor, feel free share!


Don't you think which kind of "K" makes a difference? That K2 is not the same as the K we are most familiar with? Let me know what you think, as I have been taking K2 for a year now, both to prevent bone loss and to help my heart health, as there are studies that show it gets calcium out of the blood stream where it can cause harm and into the bones.


@bulletproofexec do u have an RSS feed for us non-iTunes people?


Nicely done and agree with most points. Could perhaps have been worth nothing that calcium supplements might not be a good solution as I know lots of people popping those tablets every day. For a 2-week experiment on how to eat for healthy body amp; bones check out www.rethinkingtruth.com
