Sunshine Vitamin: Battling Winter Blues with Vitamin D

Sunshine Vitamin: Battling Winter Blues with Vitamin D

Nearly 50% of the world’s population experiences vitamin D deficiency (PubMed). If you’re one of the many who live in an environment that isn’t conducive to outdoor activities during the winter months, you’ve likely encountered the “wintertime blues.” Lack of sunlight exposure reduces our absorption of vitamin D, which significantly impacts brain function, particularly regarding depression. A 2005 study by the Journal of Chemical Neuroanatomy found that vitamin D receptors are located in areas of the brain associated with depression, which explains why vitamin D deficiency is often linked to seasonal affective disorder (SAD) (PubMed).

So, what does vitamin D deficiency feel like? Symptoms can vary, but often include:

  • Chronic fatigue, problems concentrating, low energy, or a lethargic feeling
  • Weakness or pain in the muscles, joints, or bones
  • Reduced interest, forgetfulness, and feelings of sadness, helplessness, or hopelessness
  • Increased anxiety
  • Insomnia or excessive sleep
  • Excessive weight gain or weight loss
  • Loss of sexual interest

In addition to its role in brain health, vitamin D is crucial for:

  • Maintaining bone and teeth health
  • Supporting the immune and nervous systems
  • Reducing the risk of cancer
  • Regulating insulin levels to support diabetes management (especially important for bariatric patients) (NIH)
  • Supporting cardiovascular and lung health

People who cannot obtain vitamin D from sunlight can compensate by consuming foods rich in vitamin D, such as fish, eggs, and mushrooms (NIH). For patients of bariatric surgery, the effects of vitamin D deficiency may be even more pronounced due to their reduced ability to absorb fat-soluble vitamins after surgery (ASMBS). Because of this, it’s crucial for bariatric patients to supplement their daily diet with a vitamin D supplement.

Vita4Life offers an excellent vitamin D3 supplement to help combat vitamin D deficiency. This formula contains 30,000 IU of water-miscible vitamin D as cholecalciferol (D3) (Healthline). Many high-potency products contain vitamin D2, which is not as bioavailable as the high-potency, water-miscible D3 formula. This supplement also features a certified organic 6-blend mycelia formula that offers antioxidant benefits. The mycelia formula is minimally processed to ensure maximum bioavailability of the mycelium’s protective compounds, provided in entirety, rather than isolates. These help fortify the immune system and may increase antimicrobial support (NCBI).

For those who suspect they might be experiencing vitamin D deficiency, starting a daily vitamin D supplement is highly recommended. Don’t let the wintertime blues take over this year—get proactive and ensure you’re getting enough of the sunshine vitamin!
