Vitamin And Mineral Levels Testing

Testing Your Vitamin Levels

Optimal nutritional balance is essential for the function of every cell and system in your body. However, it is becoming increasingly difficult to ensure that you are getting the right balance of nutrientsand the goal posts seem to change daily!

To assess your vitamin and mineral status, your Remède nutritionist, naturopath or doctor will start by performing a thorough assessment of your overall health and an examination of your daily dietary intake, which may include a diet diary, cellular health analysis and other tests to evaluate your vitamin and mineral status. This will give you a clear understanding of where any deficits may be and inform and empower you to make any necessary changes.

Your Remède practitioner may also recommend a nutritional profile test if you are concerned about your nutritional intake or if they are concerned about your overall levels and the impact of nutritional deficiencies on your health issues. The nutritional profile test requires a blood test.

Example of Nutritional tests include:

  • Iron

How To Choose A Home B12 Test At Home Kit:

As we touched on above, the most important things you need to consider when choosing an at-home testing kit for vitamin B12 include:

  • Check if they measure active B12 levels or total B12 levels, and choose which you would prefer. Remember total vitamin B12 levels tests are not always suitable for diagnosing a deficiency
  • Do they use accredited UKAS laboratories to test your samples? You dont want just any old lab testing your results, make sure they are the real deal
  • Do they have doctors on hand to help interpret your results? Some aftercare is sometimes necessary, especially if you have confusing results, so check if they have a doctor on board to help if needed.
  • Do they have good reviews? Check their brand website and the reviews they have received to see what other people think of their service.

How To Determine The Vitamin D3 Level

You can measure your vitamin D levels by using a blood test to determine if you have enough vitamin D in your body. In fact, not the active form of vitamin D is measured, but the concentration of 25D in the blood.

The 25 D value is a precursor of vitamin D, in which form is is transported in the blood. If necessary, this form is converted into the active form of vitamin D .

The 25 D value shows how much vitamin D you got through nutrition or produced during sun exposure. But this value does not tell you anything about your vitamin D levels throughout the year, which will vary depending on the sun exposure and vitamin D uptake from food.

The half-life of 25 Vitamin D is 2 month. This means, that the vitamin D level will fall to half of its value, provided that you no longer get any vitamin D at all.

Best Labs To Check Vitamin B12 Levels

Serum Vitamin B12: This is a simple and fairly reliable way to measure vitamin B12 levels. Many doctors believe they can surmise B12 deficiency by looking at the shape of red blood cells. While this test a complete blood count can indicate a vitamin B12 deficiency, it is not very reliable and does nothing to detect a functional deficiency. A functional deficiency is when you have a nutrient level that is considered normal by conventional standards, but the nutrient is not at an adequate level to do its job in the body optimally.

We like to see serum B12 levels at a minimum of 500 pg/mL, but prefer it to be above 900 pg/mL. We will often cross-reference this number with a urine MMA test.

Urine Methylmalonic Acid : MMA is a marker that, when elevated, indicates a vitamin B12 deficiency. We love to use this test in our practice because it shows if B12 is doing its job adequately. We have many patients who have normal serum B12 levels but an elevated MMA, meaning that they are functionally deficient.

Optimal urinary MMA levels should be below 1.0 mmol/mol. Some patients have serum B12 levels that are above the normal reference range, yet their MMA was elevated, indicating a functional deficiency. This is why functional tests like urinary MMA are so important.

When To Take A Supplement

Most people can get the nutrients they need from diet alone. So if you dont have a nutrient deficiency, you shouldnt take a supplement just for the sake of it. Synthetic nutrients dont always match up to those found naturally in foods.

A good approach is to monitor your vitamin and mineral levels with a blood test. If youre low in a certain nutrient, you can up your intake of foods rich in these nutrients. However, supplements are definitely necessary in some cases.

Vitamin D supplements During autumn and winter, Public Health England advises that everyone should consider taking a 10 mcg daily vitamin D supplement from October to March. And if youre more at-risk, they recommend taking them year-round.

If youre someone who doesnt get much sunlight during the summer months, wear sunscreen top to toe, or have darker skin, then its recommended that you take a supplement all year.

Vitamin B12 supplements If youre a vegan or vegetarian then youre more at risk of vitamin B12 deficiency. If a blood test shows that youre deficient or if you follow a strict vegan diet then its recommended that you take a supplement.

A cyanocobalamin supplement is a good choice as its a form that your body can easily use. Its also possible to get a vitamin B12 injection this is especially useful if your deficiency is caused by absorption issues in your stomach. The form of hydroxocobalamin can be given every three months.

What Is An Adequate Level Of Vitamin D

Adults under the age of 70 are advised to get 15 mcg of vitamin D per day. If you are 71 years of age or older, 20 mcg is recommended.

Previous research has explored the potentially protective relationship between vitamin D and COVID-19. A study published in August highlighted vitamin D deficiency in COVID-19 patients who experienced acute respiratory failure. An October study on 50 COVID-19 patients linked a high dose of a type of vitamin D with lower rates of intensive care unit treatment.

Given that vitamin D is involved in many bodily functions and plays an important role in immune health, Elizabeth Shaw, RDN, a nutritionist from California, recommends getting your vitamin D levels checked.

“Vitamin D concern is something I’ve seen become increasingly of interest over the last three years in my practice due to the fact so many individuals across the U.S. have low vitamin D levels,” Shaw tells Verywell. “As with everything, 2020 and the pandemic has definitely increased the public’s interest.”

Symptoms of Vitamin D deficiency include fatigue, muscle weakness, bone and joint pain, and depression.

Reverses And Prevents Anemia

This study has found that chronically low levels in vitamin D can cause anemia. This is interesting as we mostly think of anemia as a result of low iron and/or vitamin B12. We now know vitamin D can also play a role. Symptoms of anemia include deep fatigue, rapid heartbeat, difficulty concentrating, dizziness, pale skin, leg cramps, and insomnia.

Vitamin D Production Can Vary Significantly

The ability of each person to produce vitamin D through sun exposure or to increase the vitamin D level by taking vitamin d supplements, can vary significantly and depends on age, body weight, skin colour, sun exposure, and life style.

It is not said, that each person can reach the same vitamin D level by taking the same amount of vitamin D or having the same sun exposure. Some people may need more or less vitamin D per day to achieve the same level.

Therefore, the recommended rules for calculating the optimal vitamin D dosage are only indicative. To know your personal vitamin D level, a 25D blood test has to be performed. It shows you exactly how your vitamin D level is changing depending on the vitamin D intake and sun exposure.

Signs Of Nutrient Deficiency

Signs you may be missing key vitamins and minerals, and how to reverse deficiencies

Everyone knows that we need vitamins and minerals to keep our bodies healthy. But how do you know when you aren’t meeting your body’s needs?

“There are many telltale signs of vitamin and mineral deficiencies,” says Patricia Graham, MD, an internal medicine specialist at Rush University Medical Center. “But the good news is that often, if you take steps to address the deficiency, the symptoms will either improve or go away altogether.”

Here, Graham walks through six red-flag scenarios, and how you might reverse any deficiencies found.

Recommended Ranges And Dosages Of Vitamin D

Vitamin D Levels Test

If you go by the ranges found in labs or given by traditional doctors, healthy blood levels of vitamin D are from 30 to 100 ng/ml. If you are below 10, pretty much everyone agrees that you are severely deficient, and if you are below 30, the Endocrine Society and the Vitamin D Council still maintain that you are not getting enough.

Functional medicines recommended range for healthy people is 60 to 80 ng/ml, especially so for people with a family or personal health history of cancers and autoimmune conditions.

If your levels are below 60 ng/ml, functionally trained doctors recommend a dose of vitamin D3 in the range of 5,000 to 8,000 UI per day. It may take 3 to 4 months to get into a healthy range. You can then switch to a maintenance dose of 2,000 UI per day. You can easily get a blood test done to confirm it.

For people with Hashimotos Disease , its very very important for your vitamin D levels to be in the upper ranges of 60.

Readers Say Vitamin Levels Should Be Checked Yearly

Vitamin D Testing Service

Processed foods, mineral-depleted soil, overcooked vegetables, increased stress levels — all of these increase the chances of having a vitamin deficiency, according to a vocal majority of MedPage Today readers who commented on last week’s poll.

We asked readers if and when patients should be assessed for vitamin deficiencies. Of the more than 2,200 votes, 69% said that patients’ vitamin levels should be assessed at least annually.

“I cannot remember how many patients have been rescued from dementia and psychosis by B12, especially when I have a geriatric focus,” said one doctor, who also touted vitamin D, calcium, fish oil, and thyroid testing. “Everybody deserves a look about once a year.”

But once a year was not enough for some and too much for others. One cardiologist said he or she tests vitamin levels every six months with a “pick up rate over 25%.” Another commenter said that yearly testing seems too frequent. “Getting a baseline every five years with additional testing as needed seems better.”

We received several anecdotal accounts about vitamin deficiency being caught, but only when the patient requested the test.

“I was diagnosed with severe insufficiency of vitamin D and only had it tested because I requested it,” said one woman, who added that her mother and daughter were subsequently found to be vitamin D-deficient.

But what is the root cause of vitamin deficiency? “We need to start with nutrition,” was how one physician simply put it.
