Near-vegan D3 supplement with subtle effects and bottle design drawbacks, explores sunlight deficiency.
Ethical lanolin-derived D3 with subtle results; impractical bottle design led to switching brands for easier daily use.
This review is from Amazon.com for product:
Premier Research Labs Vitamin D3 Serum - Liquid Vitamin D Oil Drops for Adults, Liquid Vitamin D3 5000 IU, Sublingual Vit D3 Liquid - 0.43 fl oz
I chose this product because I wanted a vegan D3 supplement. I found that this is almost vegan, since it was made from bacteria and sheep wool extract (lanolin), at least it does not require the killing of the animal. It seems to be the closest to vegan of any D3 source. The effect is subtle for me. I seem to feel it working, but it is not as obvious as other supplements. My one reservation is the bottle. The thick serum does not pour well out of it. I ended up taking the dropper top off and pouring it directly. I have since found another near vegan D3 from another company that dilutes the formula so that it can be administered from a regular dropper bottle. This seems more practical for daily supplementation. It seems that we do need D3 and it may qualify as a mild global deficiency, perhaps due our species spending less time outdoors in a direct sunlight.
Vitamin Basics & Tips
Vitamin D3, unlike plant-based D2, is traditionally sourced from animal products like lanolin (sheep wool fat). While not fully vegan, lanolin-based D3 avoids direct animal slaughter, making it a compromise for ethically conscious users. Most humans synthesize D3 through sunlight exposure, but modern indoor lifestyles contribute to widespread deficiency. Supplements are recommended, especially in regions with limited sunlight.
Vegan-friendly D3 alternatives exist, typically derived from lichen or lab-cultivated bacteria. These options avoid animal byproducts entirely but may require higher doses due to lower bioavailability. When choosing a supplement, consider dropper design: thicker formulas often need specialized bottles to ensure accurate dosing. Always consult healthcare providers to address individual deficiency levels and absorption efficiency.
Global vitamin D deficiency is linked to bone health risks, immune dysfunction, and mood disorders. Regular blood tests help monitor levels, and combining supplements with brief midday sun exposure (10-15 minutes daily) optimizes natural synthesis. Storage matters too – D3 degrades in heat, so keep bottles in cool, dark places.
