 Do You Have Low Vitamin D Symptoms?

More than 40 percent of US adults have low vitamin D levels in their body. (1) One of the most obvious reasons for vitamin D deficiency is aging. While we cannot stop the aging process, we can surely work towards getting enough vitamin D.

As we age, we tend to eat less and spend more time indoors, especially during the winter. Likewise, old people have more fat cells in their body. All of these factors drastically reduce the levels of vitamin D in the body. 

The absorption of vitamin D from dietary sources is reduced in older people. (2) Moreover, the increased use of sunscreen products is another little-known cause of low vitamin D levels.

If you experience fatigue, bone pain (back pain), muscle pain, and low moods, you may have a deficiency. Other deficiency symptoms include brittle bones, delayed wound healing, and frequent infections.   

Vitamin D is an oil-soluble vitamin that plays crucial roles in maintaining strong bones, protecting heart and brain health, and strengthening the immune system. (3,4) A growing body of evidence also suggests that vitamin D can be an effective weight-loss aid. (5)

Supplementation with high-dose vitamin D3 not only fulfills the daily needs of vitamin D but also helps fight the symptoms of deficiency.

Why Do You Need High Dose Vitamin D3?

According to the Vitamin D Council, a daily 5000 IU of vitamin D3 is needed to achieve optimal levels of the vitamin in the body. (6)

You should keep in mind that higher doses may be required if you have a deficiency diagnosis, diabetes, certain heart disease, and chronic digestive problems. A daily dose of up to 10000 IU is safe for most adults, notes the Endocrine Society Practice Guidelines.

Toxicity with vitamin D is rare and may occur only when you take large daily doses for several months in a row.

Take one capsule of Vitamin D3 either in the morning or at bedtime. For best results, take it with food. Food can enhance its absorption.

If you have been diagnosed with vitamin D deficiency, you may take two capsules per day for a few months.   


Cholecalciferol (Vitamin D3) is More Effective than Other Forms of Vitamin D

When it comes to providing rapid and sustained benefits, not all forms of vitamin D are created equal.

Of many forms of vitamin D, the most effective one is Cholecalciferol (or vitamin D3). It is more easily absorbed into the system and provides better results than vitamin D2. (7) That’s why it is the most preferred form of vitamin D for supplementation.

Interestingly, studies have also noted that vitamin D2 supplements are more likely to be degraded by humidity and high temperature. (8) This can make vitamin D2 supplements less effective than vitamin D3 supplements.
