Safer Sunshine: Why Vitamin D3 Might Be Right For You

The days are getting longer, which means one thing: summer is near! For many of us, this is the season for spending time outdoors, soaking up as much sunshine and Vitamin D as possible.

By now, we’re all aware that too much unprotected sun exposure can be dangerous, but many still choose to ignore warnings in pursuit of the perfect tan. As we head into the sunniest season, it’s time to consider a healthy alternative to risking skin damage: Vitamin D3.

What is Vitamin D and Why Do We Need It?

Vitamin D can help with bone health, strength, and calcium absorption in the gut. It can also have a positive impact on mood, mental health, cognitive function, and overall physical health.

Ergocalciferol, or Vitamin D2, is derived from foods like tuna, mackerel, and salmon as well as mushrooms and certain dairy products. Cholecalciferol, or Vitamin D3, is synthesized within the body when our skin is exposed to UVB rays.

Benefits of Vitamin D 

• Maintains bone health
• Supports healthy eyes
• Protects teeth
• Helps regulate mood
• Supports health of the immune system, brain, and nervous system

Vitamin D Deficiency

Our need for Vitamin D increases as we age, just as our body’s ability to produce it decreases. Unfortunately, it can be difficult for those with dietary restrictions to get the necessary amount of Vitamin D. People with darker skin also absorb Vitamin D more slowly, due to additional melanin which slows synthesis by sunlight.

One study indicates that the percentage of older adults suffering from Vitamin D deficiency in the U.S. is high, landing between 20% and 100%. Research also suggests Vitamin D deficiency may be linked to age-related diseases.

Side-effects of Vitamin D deficiency can include:

• Weakened immune system
• Depression
• Increased risk of type 2 diabetes
• Cognitive impairment
• Risk of osteoporosis, cardiovascular disease, and cancer

There’s no banking sunshine, either: no matter how much sun exposure you receive, Vitamin D can only be stored in the body for 60 days. Unfortunately, during the colder months in northern regions, sun exposure can be rare. Reduced sun exposure, combined with a diet low in Vitamin D, can lead to widespread deficiencies.

Vitamin D3 Supplements

A safe and effective alternative for Vitamin D-deficient people is supplementation. Daily intake of Vitamin D3 can help maintain the healthy levels our bodies need, without the risk of skin cancer caused by excessive tanning.
