Now Foods Vitamin D improved our levels, doubled detection via supplements. Required 2000 IU dosage adjustment for optimal results. Recommended for clean formulas.

This review is from Amazon.com for product:

NOW Foods Supplements, Vitamin D-3 1,000 IU, High Potency, Structural Support*, 360 Softgels

Wife and I used this for 1 year, but we fell short on moving our vitamin D blood test detection into the normal range. This is not a product complaint because it DOUBLED the amount detected prior to adding Vitamin D to our daily supplementation diet. On direction from our doctor, we have since increased dosage to 2,000 UI and a year later we both achieved normal range. Now Foods has become our Go To for vitamins, supplements, essential oils, and even a few food items [highly recommend their "Organic Hot Cocoa" milk chocolate powder]. They are a Christian-owned company with consistently-high quality ratings. Our primary reason for buying this brand is quality and little to no additives (synthetic chemicals).

Vitamin Basics & Tips

Vitamin D plays a crucial role in bone health, immune function, and mood regulation. While sunlight is the primary natural source, supplements like Now Foods' 2000 IU tablets help address deficiencies, especially in regions with limited sun exposure. Blood tests (25-hydroxyvitamin D test) are essential to monitor levels, as symptoms of deficiency—fatigue, bone pain, or frequent infections—are often subtle. The NIH recommends 600-800 IU daily for adults, but higher doses may be needed under medical supervision, as shown in this review.

Fat-soluble vitamin D requires proper absorption: pairing it with healthy fats (e.g., avocado, nuts) enhances uptake. Unlike water-soluble vitamins, excess vitamin D can accumulate, making professional dosage guidance critical. Now Foods' focus on minimal additives aligns with safer long-term supplementation. Lastly, combining supplements with vitamin D-rich foods (fatty fish, fortified dairy) and sensible sun exposure creates a holistic approach to maintaining optimal levels.
