3 Astonishing Benefits Of Vitamin D (And How To Get The Right Amount)

Savers are aware that Vitamin D is important for bone health and immunity. But what you may not know is that this vitamin offers other incredible health benefits.

So today we’re taking a closer look at this amazing vitamin. You’ll discover what few know: Vitamin D has much to offer, from cardiovascular health to improving mood. And we’ll also delve into the important questions of how much and what kind of Vitamin D is best.

Why Is Vitamin D So Important?

Calcium is usually the mineral of choice when it comes to fighting osteoporosis. Unfortunately, this disproportionate focus on calcium has led to the development of some not-so-healthful supplements (such as calcium carbonate) and a neglect of other important bone-building minerals.

Even though it stimulates calcium absorption in the intestine, Vitamin D tends to get overlooked when it comes to bone health. Nonetheless, Vitamin D is instrumental in preventing falls, building immunity, and in regulating calcium and phosphorous during bone remodeling.

Vitamin D also gets overlooked when it comes to other aspects of health. In fact, some of the signs of Vitamin D deficiency go well beyond bones, and include feelings of sadness, high blood pressure, and chronic muscle pain and weakness.

So today we’re going to put Vitamin D in the spotlight…or rather, the sunlight!

How Does The Body Process Vitamin D From Sunlight?

Your liver manufactures a form of cholesterol called 7-dehydrocholestrerol, which acts as a precursor to Vitamin D (another reason that a healthy liver is essential for bone health!). this precursor resides in the skin, and when your skin is exposed to the UV (ultraviolet) rays in sunlight, the precursor is converted into cholecalciferol.

We’re still not there. Cholecalciferol is a “previtamin” form of Vitamin D. It travels to your liver, where it is metabolized into hydroxyvitamin D. Then the kidneys kick in and convert it into Vitamin D3, the hormone form of the vitamin that your body can use.

It’s quite an amazing process!

Now that we’ve looked at the details of Vitamin D formation, let’s get to the 3 little-known benefits of this hormone-vitamin.

1. Together With Calcium, Vitamin D Lowers Cholesterol

This could convince just about anyone that statins, the popular cholesterol-lowering drugs, are not necessary at all. Savers surely know that statins have a long list of known awful side effects, including increasing the risk of developing type II diabetes by almost 50%.

They actually block the same enzymatic pathway as bisphosphonates, which begs the question of whether or not bisphosphonates also increase diabetes risk. Thankfully, there is a much better cholesterol-management option, and a recent study further confirms this.

When a group of post-menopausal women who took 1000mg of calcium and 400IU of Vitamin D3 daily, they were found to have higher Vitamin D levels in general and lower levels of LDL, the “bad” cholesterol, than those women who took a placebo.1

Clearly, getting plenty of Vitamin D3 is beneficial to cardiovascular health and it also helps build your bones.

2. Vitamin D + Exercise = Lower Blood Sugar (And More)

A South Korean study reveals a fascinating connection between Vitamin D, exercise, and, among other things, blood sugar.

The study involved 52 elderly women, all with type II diabetes, who were divided into three groups. One group underwent circuit aerobics training for 12 weeks. (Circuit training is so called because participants perform a sequential series of exercises.) Another group did the circuit training and took 1200IUs of Vitamin D3 each day. A third group simply continued with their normal lifestyle.

Researchers found that after the 12-week period, the circuit training group had decreased weight, body fat, cholesterol, and body mass index (BMI). In the group that took Vitamin D3 and did circuit training, the results were even more positive: fasting insulin and glucose were both lower, and so was an important homeostatic model assessment and insulin resistance marker known as HOMA-IR.2

The researchers noted that

“Vitamin D supplementation was especially effective when it was complemented with exercise training,”2

Keeping blood sugar levels on an even keel is a very important aspect of bone health, too. Too much sugar damages bones and has an impact on other body systems, such as immunity and neurological function.

3. Vitamin D Relieves Depression

Prescriptions for antidepressants in the United States have skyrocketed lately. Research clearly shows that antidepressants (particularly SSRIs) increase fracture risk by almost double.

The reason is the inhibition of serotonin, which not only affects mood but also influences and regulates bone formation.

The Save Our Bones approach always includes the whole person, and recognizes that no body system works in isolation. This was startlingly revealed in an animal study that showed how depression triggers the sympathetic nervous system (SNS), which serves as a connection between your brain and your skeleton. When the SNS is “set off” by depression, it stimulates the secretion of noradrenaline, a substance that is very damaging to bones. 3

As antidepressants continue to disappoint, and the connection between depression and the physical body is becoming more well-known, Vitamin D is being taken more seriously as a depression reliever…despite “research” showing otherwise.

Prominent Doctor Points The Finger At Flawed Vitamin D3 And Depression Research

Doctor Simon Spedding, an Australian professor at the University of South Australia, conducted a meta-analysis of randomized, controlled trials (RTCs) that were intended to study the use of Vitamin D to treat depression. Dr. Spedding found some significant flaws, including interventions that did not even involve Vitamin D, where Vitamin D baseline levels were not measured, and the use of data where participants had sufficient Vitamin D levels to begin with (to name a few).

One of the most startling flaws he uncovered is that some of the RTC subjects did not even have depression to begin with.

According to Dr. Spedding’s research, the RTCs without flaws clearly show that Vitamin D effectively relieves depression symptoms.4

In fact, Vitamin D is an excellent addition to a drug-free depression treatment program that also includes exercises in positive thinking, proper nutrition, and regular exercise.

Spring Is Almost Here!

The good news is that with spring just around the corner in the Northern Hemisphere, it will be much easier to get plenty of sun-sourced Vitamin D. As Savers know, the sun is the best source of Vitamin D. It bypasses the digestive process, so even those with digestive problems can still get plenty of this crucial vitamin. Also, if you get your Vitamin D from sun exposure, you don’t need to worry about dosage. And of course, sunlight is free!

One caution: in your efforts to get Vitamin D, be careful to not usher in spring with a sunburn. It’s so easy to forget how long you’re outside on those first warm days, and as spring moves into summer, it’s even easier to forget the time you’ve spent in direct sunlight.

Why Not Just Use Sunscreen?

Savers may already know that sunscreen prevents the sun’s beneficial UV rays from hitting your skin, thus preventing the formation of Vitamin D no matter how much time you spend in the sun. And another problem with sunscreens is their toxic ingredients. Conventional sunscreens contain a host of acidifying toxins that can penetrate skin, enter the bloodstream, and damage bones.

At the Save Institute we don’t recommend using conventional sunscreens, so to prevent painful and skin-damaging burns, it’s very important to not over-expose your skin to the sun’s rays. The amount of sun needed to produce Vitamin D varies with skin tone, but a good measure of time to get started it around 20 minutes. And make sure you also take a supplement of at least 400 IUs to ensure you’re getting enough of this crucial micronutrient during the summer months, and a higher dose (up to 2000 IUs) when you’re not sunbathing or during the colder months.

Till next time,

    I would love to have one of these “SunFriends”. But unfortunately I live in Canada.
    Do you have any idea when they might be available to us?

    • Karin Edgett May 14, 2015, 8:44 am

      Hi, you can buy one on SunFriend.com and we will ship it to Canada.

  2. SA Kar March 18, 2015, 12:30 pm

    I was ready to invest the $50 bucks UNTIL I read the PC Mag review says that this product a) doesn’t buzz or notify user that ‘time is up (it flashes, but the user might not notice the flash if the user is outdoors and in sunlight); and b) can only last one year because there’s no way to replace the battery–a deal killer. So I think I’ll plan to walk outside for a while (30-40 minutes before 10AM) and then use sunblock. It would be really frustrating to invest $49.99 for something that doesn’t last longer than its battery.

    • Karin Edgett May 14, 2015, 8:48 am

      Hi, and thanks for your comments. Adding a buzzer means it can’t be waterproof, so we weighed our options. The SunFriend takes very little power to run, so it lasts up to 3 years on the current battery. We will have more products coming out that tie in with the phone, allowing for audio alerts and family monitoring and vitamin D factors.

      I will tell you that the SunFriend is very accurate, much more accurate than guessing if you are tying to get enough sun on a daily basis. Our lead designer is a physicist at NASA and this is our first product!

      • Karin May 14, 2015, 8:54 am

        The LEDs light up as you go, and you can check the SunFriend from time to time to see how you are progressing. You do not need to wait until it flashes to know what is going on with your sun exposure. 🙂

    Hi Vivian, I think this SunFriend is wonderful, thank you so much for finding it. I am going to ask my family in the U.S.A. to buy me one, & I will refund them.

    By the way, coconut oil has a 7% SPF protection – & that is all I use on my skin. When I have time, I lie in the sun for half an hour at a time, so I am as brown as a berry, without getting burnt! Coconut oil Organic original is what I use on my face & body, I also use Rose Hip oil under the coconut oil on my face. I stopped using suntan oil a long time ago. I question Vivian, will the coconut oil stop the UV from penetrating the skin?

  4. Babs Robertson March 16, 2015, 8:18 pm

    I take Fultium D3 800mg daily.

  5. Rochelle March 16, 2015, 8:16 pm

    Ava Anderson Non-Toxic offers amazing sunscreen products that are perfectly safe to use.

    • Karin May 14, 2015, 8:50 am

      Hi, yes, there are plenty of sunscreens on the market. Most of them block the UVB light – the light that turns you red when you have had too much, and the light that helps your body produce vitamin D.

  6. Maureen March 16, 2015, 6:34 pm

    I followed your advice about going out in the sun without sunscreen for a few minutes several times per week. I was very careful not to overdo it, just a few minutes each time. The good news is my Vitamin D level increased since my last blood work. The bad news is that I went to the dermatologist for my annual check up and she removed 3 moles, that were previously normal and now suddenly were not. Two were “mildly” abnormal, “one was moderate/severely” abnormal. They told me if I had not had the moderate/severely abnormal one removed that it likely would have developed into pre-melanoma within a year or so. To look at the moles one would never had guessed they were abnormal. So…. needless to say I cannot rely on natural sunlight for Vitamin D any longer. I would suggest everyone proceed with caution if you expose your skin to the sun, even for short periods. I am proof you can develop a potentially serious problem that could have been far worse than low bone density.

  7. Babs Robertson March 16, 2015, 5:54 pm

    I do take a vitamin D3 daily i have found it realy has helped my bones over last 2 years due to the fact i can’t sit in the sun cause skin problems.

  8. Patricia Holt March 16, 2015, 4:30 pm

    Being fair skinned and living in a hot climate I need to use factor 50 when I go out in summer.How much vitaminD3
    do I need to take in supplement form to get the right amount.Thank you.

  9. Lilian March 16, 2015, 4:07 pm

    I live in the tropics but I try to avoid the (hot, midday) sun because I have a light sensitive skin. I am diagnosed osteoporosis and I take a 500mg calcium supplement +800IU vit.D3 tablet daily. I also eat calcium rich food, much of it inspired by your program. I exercise 3 times a week in a gym, where the trainer is aware of my health situation. Do you think I am doing the right thing?

    • Vivian Goldschmidt, MA March 16, 2015, 5:06 pm

      Hi Lilian,
      The most “right” thing you’re doing is asking questions and gathering information! Obviously, you take care of yourself and your bones, and you’re here at the Save Our Bones site to learn as much as you can. Keep up the good work and research!

  10. nancy March 16, 2015, 1:25 pm

    I recently read that adults should avoid vitamin D.That more than400IUdayresults in calcification of coronary arteries

    • Vivian Goldschmidt, MA March 16, 2015, 1:58 pm

      The good news is, if you get your Vitamin D from sun exposure, you can’t “overdose.” 🙂

      • cindy March 16, 2015, 7:02 pm

        Vivian I have been taking 2000iu of Vit D in the morning and the same in the evening I take it with me calcium Do you think that is too much I feel great I am 73yrs young and feel 50yrs.

        • Carolyn April 2, 2015, 5:59 am

          Vivian, My naturopath has given me a Calcium Bone Maker Complex supplement which includes Ca 600mg and Vit D 1800iu to take 4 p.d. As you have said 800-1200mg p.d. for calcium is recommended I am also concerned about the Vit D. Could you please advise me.

  11. diana March 16, 2015, 10:45 am

    What was the refund policy for The Save Our Bones program?

  12. Sandra Schnitzler March 16, 2015, 9:55 am

    My sister was told by her dermatologist that the only way one gets Vitamin D3 is through your eyes. Is this true?

    • Diane Martinson March 16, 2015, 10:12 am

      She needs to change dermatologists!

      • MP March 16, 2015, 1:57 pm

        This is why I visit no dermatologist. I’m a better dermatologist than a dermatologist.

  13. Sally March 16, 2015, 9:42 am

    I have been taking vitamin D3 for many years now. My question is: if I wear the sunscreen watch and it tells me my vitamin D level has been reached for the day, does this mean I should discontinue taking my daily vitamin D3 supplement?

    • Vivian Goldschmidt, MA March 16, 2015, 12:44 pm

      It’s up to you, Sally, but it is likely that you’ll get sufficient Vitamin D from regular, timely sun exposure. 🙂

  14. Rose March 16, 2015, 8:06 am

    What type of Vitamin D supplements are the best to take? I have read that some are not worth taking.

    • imtiaz March 16, 2015, 9:26 am

      waiting for sunFriend to be available out of US.

    • Geoff March 16, 2015, 9:07 am

      I can recommend and have taken ‘Natures Plus vitamin D3 5000iu’ for over 2 years and my bone Dexa scan has improved. I took these instead of having to have biphosphonates and they worked for me.

  15. diana March 16, 2015, 6:39 am

    Vivian, Sunday I e-mailed you the results of my latest bone density test. It showed that after being on your program for over a year the bone density in my forearm and spine had decreased. The density in my hip increased by .03. I have followed the diet the best I can, I exercise (with and without weights) walk 2 to 5 miles 5xs a week.Also take most the vitamins you recommend. So my question to you again today is what should i do now.

    • Vivian Goldschmidt, MA March 16, 2015, 12:25 pm

      Keep up with the Program. Remember that there’s more to bone health than bone density. Tensile strength is just as important, and the great thing is that you didn’t break any bones! Good job 🙂

      • diana March 17, 2015, 12:59 pm

        Vivian, “Lucky i didn’t break a bone” your attitude, your answer and program stink.

  16. Sheena March 16, 2015, 6:32 am

    So sad that SAVE OUR BONES can’t offer items to those savers outside the US.

    Understandable but sad.

  17. sushma March 16, 2015, 6:08 am

    How can someone not wear a sunscreen of they work outdoors all day? This surely has to be taken seriously. What is the best advice here?

    • Vivian Goldschmidt, MA March 16, 2015, 12:24 pm

      Sushma, instead of sunscreen you can protect yourself with a wide-brimmed hat, and light-colored clothing.
