How Do You Get Vitamin D And Calcium

New recommendations for taking calcium & Vitamin D

Your body makes Vitamin D when your skin is exposed to sun, but several factors limit its creation:

  • Living anywhere in the country above latitude 33 degrees

  • Wearing sunscreen to protect against melanoma

  • Having naturally dark skin

  • Aging, which changes absorption ability

  • The amount of sun you would need to achieve normal blood vitamin D levels is probably more than is safe for your skin, so most people may need supplements to achieve a normal vitamin D level.

Either form of vitamin D benefits the body, but very few foods naturally contain the nutrient or are fortified with it. Thats why doctors recommend supplements to make up the difference. Foods containing vitamin D include:

  • Cod liver oil: 400-1,000 IU per teaspoon

  • Wild caught salmon: 600-1,000 IU per 3.5 oz

  • Farmed salmon: 100-250 IU per 3.5 oz

  • Canned salmon: 300-600 IU per 3.5 oz

  • Canned sardines: 300 IU per 3.5 oz

  • Canned mackerel: 250 IU per 3.5 oz

  • Canned tuna: 236 IU per 3.5 oz

  • Fresh shitake mushrooms: 100 IU per 3.5 oz

  • Sundried shitake mushrooms: 1,600 IU per 3.5 oz

  • Egg yolk: 20 IU per yolk

Milk, orange juice, infant formula, yogurt, margarine, butter, cheese and breakfast cereals are often fortified with vitamin D.

Calcium is found in:

Kirkland Signature Calcium Citrate Magnesium And Zinc

Kirklands calcium offering might be the most cost-effective calcium supplement on the market. Its formulation employs calcium citrate to deliver the promised calcium, as well as magnesium oxide and zinc oxide for the other three minerals included in the tablets.

Each tablet provides 250 mg of calcium, 40 mg of magnesium, and 5 mg of zinc.

Not only that, it can hold its own in the analytical lab, too. The analytically determined calcium content is exactly 250 mg per tablet, though its vitamin D content is actually about 30% higher than the claimed value. This is not a concern, as vitamin D can be taken in much higher doses without any ill effects.

Two Keys To Strong Bones: Calcium And Vitamin D

Image: memoriesarecaptured/Thinkstock

Although bone-weakening osteoporosis is quite common among older people, it isn’t an inevitable part of aging. There’s a lot you can do to shield your bones from this disease.

The best insurance against osteoporosis is building the highest bone density possible by your 30s and minimizing bone loss after that. But if you you’re already in midlife or beyond, there is still much you can do to preserve the bone you have and perhaps even to replace lost bone. Daily weight-bearing exercise, like walking, is the best medicine. Getting enough calcium and vitamin D are two other critical strategies for keeping bones strong.


Calcium is an important nutrient for building bone and slowing the pace of bone loss. But it’s not a single magic bullet, and some scientists suggest that too much calcium or dairy products may be unhealthy. Keep in mind that in addition to calcium, there are other nutrients and foods that help keep your bones strong most importantly vitamin D, but also vitamin K.

How much calcium? The recommended daily intake for calcium is 1,000 milligrams a day for adults up through age 50 and 1,200 mg a day for people ages 51 and older, when bone loss accelerates. With age, the intestines absorb less calcium from the diet, and the kidneys seem to be less efficient at conserving calcium. As a result, your body can steal calcium from bone for a variety of important metabolic functions.

People At Risk Of Vitamin D Deficiency

Some people will not make enough vitamin D from sunlight because they have very little or no sunshine exposure.

The Department of Health and Social Care recommends that adults and children over 4 take a daily supplement containing 10 micrograms of vitamin D throughout the year if they:

  • are not often outdoors for example, if theyre frail or housebound
  • are in an institution like a care home
  • usually wear clothes that cover up most of their skin when outdoors

If you have dark skin for example you have an African, African-Caribbean or south Asian background you may also not make enough vitamin D from sunlight.

You should consider taking a daily supplement containing 10 micrograms of vitamin D throughout the year.

Factors To Consider While Choosing The Best Calcium Products

Calcium, Calcium Supplements & Vitamin D – What You Need To Know
  • Purity

Before you even think of using the best calcium supplements, you must be aware of several factors. One of the most significant things to look after calcium supplements is the purity of the product. We advise you always to choose a supplement that is under the certification of USP. In that way, you will know that a particular calcium pill does not contain levels of lead and other toxic ingredients.

  • Absorbability

The best supplements we have recommended to you are 100% safe and pure with a high level of absorbability. The calcium supplements must be absorbable so that you cant have stomach issues. But in case you choose other calcium supplements, you can always check this feature by putting them into a small amount of water for 30 minutes. If these calcium supplements are not dissolved at this time, they will probably not dissolve in your stomach either.

  • Tolerance

These calcium capsules are highly effective for your overall health but can still cause some effects if misused. We dont recommend using these supplements in larger amount than advised. If your body doesnt tolerate these calcium supplements, we advise you to see a professional and start with another form of using this effective mineral.

Vitamin D Deficiency: Are You At Risk

Vitamin D deficiency occurs when you are not getting the recommended level of vitamin D over time. Certain people are at higher risk for vitamin D deficiency, including:

  • People who spend little time in the sun or those who regularly cover up when outdoors
  • People living in nursing homes or other institutions or who are homebound
  • People with certain medical conditions such as Celiac disease and inflammatory bowel disease
  • People taking medicines that affect vitamin D levels such as certain anti-seizure medicines
  • People with very dark skin
  • Obese or very overweight people and
  • Older adults with certain risk factors.

Talk to your healthcare provider if you have any of these risk factors. If you have osteoporosis and also have a vitamin D deficiency, your healthcare provider may temporarily prescribe a high dose of vitamin D to bring you up to a healthy level.

What Form Of Calcium

The calcium in supplements is found in combination with another substance, typically carbonate or citrate. Each has benefits and downsides. Calcium carbonate supplements tends to be the best value, because they contain the highest amount of elemental calcium . Because calcium carbonate requires stomach acid for absorption, it’s best to take this product with food. Most people tolerate calcium carbonate well, but some people complain of mild constipation or feeling bloated. Some well-known calcium carbonate products include Caltrate, Viactiv Calcium Chews, Os-Cal, and Tums.

Calcium citrate supplements are absorbed more easily than calcium carbonate. They can be taken on an empty stomach and are more readily absorbed by people who take acid-reducing heartburn medications. But because calcium citrate is only 21% calcium, you may need to take more tablets to get your daily requirement. Calcium citrate products include Citracal and GNC Calcimate Plus 800.

Recommended Daily Intakes Of Calcium And Vitamin D

Getting enough calcium in your diet helps prevent osteoporosis. Calcium is measured in milligrams that you need per day.

  • If youre between the ages of 19 and 50, you need 1,000 mg of calcium every day.
  • If youre female and are age 51 or older, you need 1,200 mg of calcium every day.
  • If youre male and are between the ages of 51 and 70, you need 1,000 mg of calcium every day.
  • If youre male and are age 70 or older, you need 1,200 mg of calcium every day.

  • If youre over 70 years of age, you need at least 800 IU of vitamin D every day.

If you have osteoporosis, you might need more calcium, vitamin D, or both. Talk with your doctor or clinical dietitian nutritionist about how much you need per day. Dont take more than your daily recommended amount of calcium. Taking too much can be harmful to your health.

Who Should Buy Calcium

Calcium supplements are primarily useful for people looking to retain or improve their bone mass, as well as prevent fractures related to low bone density.

People who will benefit from a calcium supplement can be placed into one of three categories. The first is older adults who already know they have low bone density. For them, supplemental calcium is a scientifically validated way to slow the rate of bone loss and decrease the risk of fracture.

The next category of people who can benefit from a calcium supplement are middle-aged adults who want to ensure they maintain their already-strong bone density. For these users, combining calcium supplementation with regular exercise is a good way to maintain strong bones throughout adulthood.

Finally, female teenagers can take advantage of the effects of calcium to actually build up substantial amounts of bone density.

Partially due to the hormonal changes that happen during puberty, girls who do not have sufficient calcium intake will not increase their bone density as much during puberty, and the gap between calcium-deficient and calcium-sufficient girls in terms of bone density lasts for the rest of their lives.

The Confusing Research On Calcium Supplements

Taking Vitamin D and Calcium Together

Although we know that calcium plays a vital role in the body and that consuming enough calcium from foods is very important, the research on calcium supplements is less clear. Many supplement companies still make claims about how their product might benefit you, and these promises are not necessarily backed by quality research. Lets look into a few areas where calcium supplementation may or may not be beneficial.

Are There Clinical Studies That Show Its Efficacy And Safety

Theres one study that shows postmenopausal women over the age of 50 who took Os-cal reduced their risk of hip fracture by 29%.

Now, that may seem like an impressive number. But there are a few important things to bear in mind

Number one: the participants in this study didnt increase their bone density. The group that took Os-cal had slightly better hip bone density compared to the group that took a placebo, but they still lost bone density while on this product.

So, at best, Os-cal may slow annual bone loss, but it wont increase bone density.

Number two: the reported 29% reduced risk of hip fracture is based on something called hazard ratio. Now, hazard ratio is a bit like relative risk. But instead of measuring risk over the entire course of a study, hazard ratio measures risk at any given moment.

Heres the thing: measurements like relative risk and hazard ratio may seem impressive. But taken out of context, these percentages can appear more significant than they really are. Thats why absolute risk is a more accurate measurement. Absolute risk simply compares the difference between two sets of data.

Lets take this Os-cal study as an example:

  • In the group that took a placebo, there were 199 hip fractures.
  • In the group that took Os-cal, there were 175 hip fractures.

Based on this data, absolute risk for hip fracture would be:

  • 199 of 18,176 participants = 0.16
  • 175 of 18,106 participants = 0.14

How Much Vitamin D And Calcium Do You Need

The Endocrine Society and The Institute of Medicine have suggested recommended daily allowances for vitamin D and calcium, as well as maximum daily consumption amounts that you should not exceed for your safety:


The recommendations come with two precautions:

  • Some people may need more than the RDA if they are:

  • Obese

  • Taking anticonvulsant medications, glucocorticoids, antifungals such as ketoconazole or medications for AIDS

  • Taking too much of either nutrient appears to be harmful, with:

  • Kidney stones associated with too much calcium from supplements

  • Very high levels of vitamin D potentially causing kidney and tissue damage
