This is one of the most effective Vit D that I have ever used! **Q: My bottle says 50 mcg, however it does not say 2000 iu? How do I know it contains that amount?** A: 50 mcg = 2000 iu (in other words, it's the same thing) **Q: Is this product still absorbed well seeing as it does not contain vitamin K2 like most vitamin D supplements do?** A: On the whole, drops are better absorbed than tablets. I take K2 and magnesium to help absorption concurrently with any D3....and with this specific product. No D3 should stand alone for optimal absorption. With this product, recommended by my doctor, I know that I am getting a high quality D3 with which I realize is best to not take alone for optimal absorption. **Q: In the description it says it is vitamin d3, but on the bottle label it does not mention vitamin d3. is it d3?** A: Yes it is d-3.

They are in Canada and have high quality products. They utilize good quality control when producing all lines of their supplements. Many other companies aren't as fastidious in their product quality. This Vitamin D product is easily assimilated by the body for best absorption into circulation. Highly recommend. ## Frequently Bought Together - Biotics Research Bio-D-Mulsion Forte Liquid Vitamin D Drops 4000 IU – Vitamin D3 2000iu /Drop for Adults –Best Absorption, Strengthens Bones, Supports Cardiovascular & Immune System -1 fl oz - Biotics Research Bio Ae Mulsion IU Emulsified Vitamin A for Greater Uptake & Utilization, Concentrated Form, Promotes Immune Response, Aids in Visual Acuity, Supports Cardiovascular 1 Fluid Ounces - Biotics Research Bio K Mulsion Liquid Vitamin K Drops - 500 mcg/S - Vitamin K1 phytonadione for Adults - VIT K Supplement - Strong Bones, Heart Health, Blood Clotting Support, 1 fl oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/15521813-bio-d-mulsion-forte-liquid-vitamin-d3-drops-4000-iu](https://www.desertcart.kr/products/15521813-bio-d-mulsion-forte-liquid-vitamin-d3-drops-4000-iu) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-09-04*
