Vitamin D, also known as the Sunshine Vitamin (since the body produces it when exposed to sunlight) plays a critical role in our bone and mental health. Despite the popularity it gets, a great portion of the global population remains deficient because of indoor lifestyles, restricted sun exposure and dietary habits.
Unlike other Vitamins that come through food, it is more like a hormone that influences bone health, mood stability, immune system health, and cardiovascular health.
Since natural sources of Vitamin D are very limited – egg yolk, fatty fish, and fortified foods – it can be difficult to get enough nutrients through Vitamin D foods alone. This, added to the fact that people don’t get enough of it because of seasonal conditions, skin protection measures, makes it important to consider adding Vitamins supplement in lifestyle. But how do you know whether you are deficient or even prone to the nutrient’s deficiency, or how Vitamin D impacts your health, and how much of it you need?
Let’s answer all of that in this article today.
How to Know You are in Vitamin D Deficient or Prone to be
One of the biggest challenges with low Vitamin D is that the signs – general fatigue, stress, premature aging – start showing gradually, so people are usually unaware that they are in deficit.
However, there are some Vitamin D deficiency symptoms which indicate it’s time to act.
Signs that you are having Vitamin D deficiency
- Slow recovery and frequent illnesses – Vitamin Ds are important for immune system functioning, so if you are finding yourself catching cod often, you might be in deficit.
- Low energy and chronic fatigue – Felling sluggish, tired, or facing lack of motivation – all can be a sign of low Vitamin D in your body.
- Joint and bone pain – Unexplained muscle weakness, cramps, or pain in adults can all be a sign of low Vitamin D component.
- Depression or mood changes – There are several research that suggest Vitamin D can cause mood swings and depression like state.
- Hair loss – Severe deficiency of Vitamin D has been linked with conditions like hair shedding and thinning.
Who is at Most Risk?
- People with limited exposure to sun
- Darker skin tone people have higher melanin which lowers skin’s ability to synthesize Vitamin D through sunlight.
- Older adults
- People with digestive issues like crohn’s disease, IBS, or celiac disease.
If you suspect a Vitamin D deficiency based on this list, we recommend doing a simple blood test followed by a physician visit to check if you need to up your intake.
The Importance of Vitamin D
While popular for its role in maintaining skeletal health, Vitamin D leaves an impact on more than just bones.
Here are some lesser known impacts of Vitamin D on the overall well-being of our body.
Strong teeth and bones
One of the critical functions of Vitamin D is to help our body absorb phosphorus and calcium – the two minerals which are key to maintaining bone strength and density. The absence of sufficient vitamin D, can cause several issues to come up – brittle bones, osteoporosis or rickets, increased risk of fractures, etc.
Supports immune system
Vitamin D has a direct impact on how well our body is able to fight infections, lower inflammation, and reduce the chances of autoimmune diseases. There are several studies which show how the nutrient can help with both lowering the severity of the illness and improving the recovery rate.
Improved heart health
There are a number of emerging research which are hinting at the role of Vitamin D in supporting cardiovascular health by maintaining blood pressure, lowering arterial stiffness, and reducing inflammation.
By maintaining proper Vitamin D levels you can protect your circulatory and heart system from long-term and severe damage.
Impact mood and mental health
Vitamin D plays a key role in producing serotonin, the ‘feel-good hormone’, which maintains emotions and moods well-being. So a deficiency in the nutrient can lead to a greater risk of anxiety, depression, or seasonal affective disorder, especially during the winter months. To prevent this, physicians often recommend a weekly intake of Vitamin D supplements.
May lower the probability of chronic diseases
There are a number of studies which hint at the use of Vitamin D to prevent diabetes, certain cancers, and multiple sclerosis. The element is known to regulate cell growth and inflammations – the main contributors of disease progression.
Support cognitive function
Vitamin D receptors are present all across the brain, defining its importance in memory retention and cognitive function.
It is even believed that a healthy management of Vitamin D levels can prevent serious brain diseases like alzheimers and dementia, since it supports nerve signaling, reduces brain inflammation, and supports neurons.
Regulates blood sugar levels
Vitamin D tends to have an impact on insulin sensitivity and sugar regulation, which have a role to play in diabetes levels. It is believed that Vitamin D deficiency can cause insulin resistance making us more prone to Type 2 diabetes. Thus maintaining optimal levels can improve glucose metabolism and lower diabetes related complexities.
How Much is Too Much Vitamin D?
While we have established how Vitamin D is a key element for our well-being, the reality is that when it comes to vitamins, both ends of the spectrum – Vitamin D deficiency and Vitamin D in excess are bad for our body.
This means that it is important to know how much of it your body needs. A sure short way to know this is by talking to a health practitioner, but there is a general safe limit as well which you can follow.
- Infants (0-12 months) – 1000 to 1500 IU
- Children (1-8 years) – 2500-3000 IU
- Pre-teens, Teens and Adults (9+ years) – 4000 IU
While these ranges are shared by general guidelines set by the National Institutes of Health, doctors might prescribe a higher dose for a short period of time to replenish low Vitamin D levels.
Signs of Vitamin D Toxicity
Constantly increasing the intake of Vitamin D, can cause calcium levels to elevate, leading to –
- Loss of appetite, vomiting, and nausea
- Excessive thirst and frequent urination
- Kidney stone or kidney damage
- Calcium buildup in soft tissues and bone pain
- Weakness and fatigue
In order to avoid vitamin D toxicity, it is critical to talk to a doctor before you introduce Vitamin D supplements in your lifestyle. Post then, you should constantly monitor blood levels and stick to daily recommended intake.
We hope that you now have complete information about the powerhouse nutrient that backs everything from your immune system and bone health to mood regulation. Remember, the key is to keep the intake level in the limits set by your healthcare professional for long-term physical and mental well-being.
