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
Reordering now. The bottle lasted TWO YEARS at 1 drop a day and lifted my blood vitamin D levels to normal. I mix it in my first coffee every morning. Love this product.
previous review
Be careful when you are opening the bottle and putting the brand new glass dropper in. I overflowed this super potent vitamin d oil all over my hand, not realizing there wasn't room in the container for the dropper. You have to gently suck up some of the oil inside the bottle to make space for the dropper. I believe some warning like a note or sticker would be helpful.
Vitamin Basics & Tips
Vitamin D plays crucial roles in bone health, immune function, and mood regulation. Liquid supplements like these drops offer enhanced absorption compared to tablet forms, as vitamin D is fat-soluble. The standard daily recommendation for adults is 600-800 IU, though deficiencies may require higher doses under medical supervision.
Proper storage in cool, dark places preserves potency. The dropper technique mentioned in reviews highlights an important consideration - many concentrated supplements expand slightly with temperature changes. Leaving adequate headspace prevents leakage. Users should always wipe dropper tips after insertion to maintain hygiene and prevent contamination.
Morning consumption with coffee (a fat-containing beverage) aligns with best practices for fat-soluble vitamin absorption. Blood level testing remains essential, as evidenced by the reviewer's success story. Those using long-lasting supplements should note expiration dates, though proper storage often maintains efficacy beyond typical 1-2 year guidelines.
