My Pure Vitamin D3 Solution for Cloudy WA Days

Living in the wonderful but not so sunny state of WA I need a vitamin D3 supplement. I did not like spending a lot of money on buying pills on top of whatever junk/fillers they put in with it. This little package will last me a very long time. The suggested serving size is incredibly small, 46mg and it is highly encourage to pick up a scale that can handle that weight. I went with the American Weigh Scales GEMINI-20 Portable MilliGram Scale, 20 by 0.001 G that I saw other people posting on here and it works great.

I was very happy with my purchase and plan on buying most of my supplements from bulksupplements.

Pros:

Simple clean packaging and product with no fillers.

Huge amount of serving sizes even with the smallest package.

Cons:

For those who do not have a way to measure milligrams, they might need to buy a scale or something to measure the small units.

Vitamin Basics & Tips

Why Vitamin D3 Matters for Cloudy Climates

Vitamin D3 is crucial for bone health, immune function, and mood regulation. People in areas with limited sunlight (like Washington State) often struggle to get enough from natural sources. This explains the user's reliance on supplements to maintain optimal levels.

Understanding "No Fillers" in Supplements

Fillers are inactive ingredients added to pills for bulk or texture. The reviewer prioritizes purity, avoiding additives that may cause allergies or reduce potency. Bulk powder supplements eliminate this concern, offering concentrated doses without unnecessary compounds.

Milligram Measurement & Precision Scales

The tiny serving size (46mg) requires a high-precision scale like the Gemini-20 (accurate to 0.001g). Proper dosing ensures safety and cost-effectiveness, as overdosing can lead to toxicity, while underdosing defeats the purpose.

Long-Term Value of Bulk Supplements

A single purchase lasts months or years, reducing packaging waste and frequent costs. This aligns with the user's goal of affordability and sustainability.

FAQs About Vitamin D3 Supplementation

Q: How much vitamin D3 do I need daily? Most adults require 600-800 IU, but those in cloudy regions may need 1,000-2,000 IU. Consult a healthcare provider for personalized advice.

Q: Can I get vitamin D from food? Fatty fish, fortified dairy, and egg yolks provide small amounts, but sunlight and supplements remain primary sources for many.

Q: What are signs of vitamin D deficiency? Fatigue, bone pain, frequent infections, and low mood. A blood test can confirm levels.
