What Causes Vitamin D Deficiency

âï¸?Top 14 Signs of Vitamin D3 Deficiency You Need to Know

Your body can manufacture small amounts of vitamin D when you’re exposed to the sun. In addition, vitamin D is found in a number of foods, including fatty fish, egg yolks, beef liver and mushrooms. The nutrient is also added to some dairy products and breakfast cereals. People who are severely lacking in vitamin D may develop a condition called rickets, which causes the bones to become soft. Vitamin D deficiency symptoms may also include muscle weakness and pain can also stem from low vitamin D levels. People who are most likely to become deficient of vitamin D may include individuals who spend all of their time indoors, infants who are exclusively breastfed and those who cover all of their skin for style or religious reasons. Vitamin D deficiency can often be addressed with supplements.

The Final Verdict On Vitamin D

No bones about it, the endocrinologists we interviewed agree with our dermatologist.

“Just being outdoors, you get a fair amount of sun exposure and some sun-related generation of vitamin D, says Dr. Insogna. Because skin cancer, particularly melanoma, can be such a devastating disease, it’s best to use sunblock when outdoors in strong sunlight for any prolonged length of time. Because this may limit the amount of vitamin D you get from sun exposure, make sure your diet includes sources of vitamin D from foods or supplements, he says.

Both your skin and your bones will thank you.

Cod liver oil is incredibly easy to add to your diet. It comes in many forms, but liquid and capsule forms are the most common.

There are no set guidelines for cod liver oil intake, so most recommendations are based on safe intake levels of omega-3 fatty acids, vitamin A and D.

A common dose is often 12 teaspoons, but taking up to one tablespoon per day is usually safe. Higher doses are not recommended, as they would result in excess vitamin A intake .

Although cod liver oil is extremely healthy, some people need to be cautious about their intake since cod liver oil can act as a blood thinner.

So check with your doctor before taking cod liver oil if you take blood pressure or blood thinning medications.

    Too much vitamin D can cause toxicity that results in nausea, vomiting, poor appetite, constipation, weakness and weight loss. It can also raise blood calcium levels, causing mental status changes such as confusion and heart rhythm abnormalities.

    Sun exposure is unlikely to result in vitamin D toxicity. Other compounds produced in the skin protect the body from synthesising too much vitamin D during periods of prolonged sun exposure. Vitamin D toxicity is likely to occur from overdose of vitamin D supplements. People taking vitamin D supplements should never exceed the recommended dose and should be made aware of the side effects of vitamin D overdose.

    Drug Interactions Of Vitamin D2 Vs D3

    Why do we need vitamin d3 by OTH Health

    Vitamin D2 and D3 each are metabolized by the liver to 25D, and therefore the potential drug interactions are similar for both forms. Vitamin D may increase the serum levels of aluminum when taken with aluminum hydroxide, a common antacid, and therefore the combination should be avoided. Thiazide diuretics, such as hydrochlorothiazide, may increase the chance of vitamin D raising calcium levels in the blood to a dangerously high level. Patients on both thiazide diuretics and vitamin D supplementation should be monitored for this effect by their healthcare provider. Some drugs may decrease the absorption and effectiveness of your vitamin D supplement. Bile-acid sequestrants, such as cholestyramine, are an example of a drug which will impair vitamin D absorption. Vitamin D and cholestyramine should not be administered at the same time.

    The following table may not be a complete list of drug interactions. Please consult your pharmacist or healthcare provider for more information and a complete list of interactions.
