2021's Top 5 Supplements for Stronger Bones (#1 is an Award Winner)

What to look for and what to avoid in a quality bone health supplement

Advertiser Disclosure

Our bones not only protect our brain and organs, but allow us to walk, sit, bend, and perform daily tasks. But despite their importance, it's easy to take bone health for granted.

Unlike a sore throat, an upset stomach, or a twisted ankle, we usually will not feel it if our bones are in trouble.

Why Is Bone Density So Important?

Humans lose 1-2% of their bone density every year after age 501; meaning you can have frail bones without knowing. That's why a bone density scan is so important. Unfortunately, most people only find out they have bone density issues after suffering from a broken bone.

The fact of the matter is that, after age 50, half of all women and a quarter of all men will break a bone due to low bone density. Even worse, 50% of those who break a hip later in life never fully recover, 10% end up in a nursing home, and 33% die within a year. 2

But there is good news — when taken regularly, quality bone health supplements can help prevent fractures, stave off density loss, and actually help us gain density.  

Smarter Reviews evaluated 74 different bone health supplements on the market today. We've broken down what to look for, the dangers of calcium, and what to avoid when shopping for a bone health supplements. Plus, we'll show you our Top 5 available today.

How Can a Bone Health Supplement Help?

  • Helps Strengthen Bones
  • Supports Normal Bone Density
  • Works to Minimize Bone Loss
  • Helps Prevent Build Up Of Calcium In Arteries
  • Defends Against Fractures

Unfortunately, most bone health supplements lack the combination of ingredients necessary to improve bone density, and rely too heavily on calcium alone. With a variety of bone health supplements on the market, we looked at common pitfalls to help you make the most informed choice possible.

Look For These Supplement Ingredients:

Vitamin K2

Vitamin K2 helps calcium absorb into your bones rather than into your arteries. Make sure to take a clinically backed version of Vitamin K2, such as MenaQ7®. 3

Cissus Quadrangularis

This plant extract helps increase bone strength and even helps reduce fracture healing time.5

Vitamin D3

Vitamin D3 promotes calcium absorption and proper mineral deposits to your bones. 6 Vitamin D3 has also been shown to help boost muscle coordination, decreasing the chances of falling the first place. 7

Calcium Hydroxyapatite

Calcium Hydroxyapatite is a more easily absorbable, whole mineral form of calcium, which makes up the substance of your bones. It is notably different from other forms of calcium like calcium citrate and calcium carbonate, which do not get absorbed.

Your Definitive Bone Health Supplement Checklist:

Money-Back Guarantee

If a company is offering a 90-day 100% money back guarantee, that likely means they are confident in their product’s effectiveness. This shows the company is being transparent, and willing to allow customers to try their product for themselves and make their own decision.

Clinically Recommended Dosages

Although many brands do use quality ingredients, what’s more important are the dosage numbers. Just because a product is offering all the correct ingredients, doesn’t mean it’s going to be effective. Make sure they are in their recommended dosages in order to experience optimal results.

Doctor Formulated

It takes years of study and specific expertise to formulate an effective bone health supplement. That’s why the highest quality supplements are most likely formulated or endorsed by a doctor.

The Problem With Calcium Supplements:

A lot of calcium supplements promise to improve bone health. However, it's important to note that relying on calcium alone is simply not enough. Even worse, it can be dangerous.

While most people get enough calcium from their diets, the problem is that it's not easily easily absorbed by our bodies. In fact, studies show that certain kinds of calcium (such as calcium citrate and calcium carbonate) are almost completely unabsorbable, and essentially useless.

To ensure maximum absorption, look for Calcium Hydroxyapatite that's paired with vitamins D3 and K2. This unique pairing has been clinically proven to help support bone density better than calcium supplements alone.

Fortunately, a select few brands addressed this problem head on and have developed products that actually fix the problem.

Now that you know the benefits of a bone health supplement, what to look for, and what to avoid, what are the best bone health supplements to choose from? Below, you can find our Top 5 brands we found to be most helpful in improving bone health.

5/10

PROS

  • Vitamin D3
  • Vitamin K2
  • Complementary ingredients
  • All-natural, vegetarian ingredients

CONS

  • Not backed by a doctor
  • Frequently out of stock
The Bottom Line

Essential Elements' Bone boost was our second choice because of its well-sourced and complementary ingredients.

It contains a clinically recommended amount of Calcium Hydroxyapatite, Vitamin D3, and K2. This formula also gets bumped up a notch due to the C. quadrangularis, which enhances bioavailability.

These ingredients work well together in strengthening and maintaining bone health through the stimulation of proteins and the absorption of calcium.

They also have a 90-day money-back guarantee, which is enough time to know whether or not you'll be satisfied with it.

The formula is a clear winner, but we had to knock it down because it's not backed by a certified physician.

PROS

  • Vitamin D3
  • Vitamin K2
  • Vegetarian
  • Offers full refund

CONS

  • Lacks C. Quadrangularis
  • Contains fillers
  • Vitamin K2 not clinically studied

This product by New Chapter ranked high on our list for its good list of well-sourced ingredients.

It contains crucial ingredients like Vitamin D3 and Vitamin K2, though the quantities it provides per serving are somewhat low (25mcg and 45mcg, respectively). Its Vitamin K2 is also not clinically studied, so we can't be sure of its effectiveness.

 It also contains some fillers, such as soy and silicon dioxide, which do not offer any nutritional value.

This said, New Chapter does source its product from bioavailable algae and is vegetarian, earning it a spot on our list.

PROS

  • All-natural
  • Well sourced
  • High in nutrients

CONS

  • Actual nutrition facts unclear
  • Not doctor-backed
  • Unclear/no money-back guarantee

This product by Ancestral Supplements is another great choice to support bone health. It prides itself with an all-natural, grass-fed bone marrow that they link directly to improving bone health.

Though it is clear that this bone marrow supplement is rich in many beneficial nutrients like Vitamins D and K2, it is unclear how much of is in each product. It also recommends taking 6 tablets daily, which is a bit inconvenient.

This said, Ancestral Supplements' product is very well sourced and is an all-natural, unique approach to improving bone health.

  • Vitamin D3
  • Vitamin K2
  • Doctor-Backed

CONS

  • Low amounts of crucial ingredients

AlgaeCal Plus is a great bone health supplement with a short list of ingredients, using USDA organic algae as its foundation.

The supplement is slightly lacking in Vitamin D3 and Vitamin K2, though. It also does not have C. quadrangularis to improve bioavailability, and it does contain fillers such as magnesium stearate and silicon dioxide. Its Vitamin K2 is also not clinically studied, so we can't be sure of its effectiveness.

This said, AlgaeCal comes with a one-year money-back guarantee and uses a well sourced list of ingredients, earning it a spot on our Top 5 list.
