Why Our Bodies Need Vitamin D Supplementation

Nutrition changes are easier to keep when your kitchen, meals, and supplement routine point toward the same goal.

Support the goal

Overview

Use this article as a practical way to think through your next wellness step. The goal is not a complicated routine; it is a clearer one you can return to consistently.

The year is 1817, void of our current-day electronics, processed foods, and 8+ hour desk job work days. The farming and agriculture industry reigns, where 90% of the population lives on a farm and produces their own food.

This lifestyle encouraged ample amounts of sunlight to be absorbed into the skin thus, producing Vitamin D for our bodies to use. In those times, Vitamin D deficiencies were not an issue like they are today.

Vitamin D is a unique vitamin in that our bodies do produce it, but as our habits change and we age, it becomes harder to trigger its production. Natural Vitamin D food sources are very limited and only include fish and egg yolks. Some foods can be fortified with Vitamin D, but natural sources are the best way to obtain the Vitamin.

This is where it becomes problematic for us today. We are already faced at a disadvantage with such a limited number of food sources where we can access Vitamin D. Couple that with the fact that our population hardly spends time outside in the natural sunlight like we did 200 years ago. We are hit with a double whammy where Vitamin D deficiencies seem inevitable.

Useful reset points

Notice

Start with the pattern you can actually see

Energy, sleep, digestion, mood, movement, and recovery all leave clues. Paying attention to the pattern makes the next step more useful.

Simplify

A smaller routine is easier to keep

Choose one or two habits that fit your real week. Food quality, hydration, movement, sleep, and stress recovery usually matter before complexity.

Support

Match supplements to a specific priority

A focused supplement routine works best when it supports a clear goal and sits alongside the basics you already repeat.

Vitamin D is essential for our bone, cardiovascular, and neuromuscular health. It is for these reasons that we require Vitamin D supplementation. The recommended dietary allowance of Vitamin D for adults aged 51-70 years is 600 IU. For adults over 70 the amount increases to 800 IU (U.S. Department of Health and Human Services). With our modern lives that are mainly spent indoors, we simply cannot naturally produce these amounts resulting in us relying on supplementation to keep us healthy.

Make sure you are being proactive about your health and being intentional when it comes to obtaining Vitamin D and seeking out supplementation.

Be sure to speak with your health care professional before you start taking a Vitamin D supplement.

Common questions

Where should I start?

Start with one clear priority, then choose the food, movement, sleep, hydration, or supplement step that best supports it.

Do supplements replace the basics?
