Hypoallergenic and free from common allergens and artificial additives, this physician-trusted supplement has been a clean, therapeutic choice since 1969, ideal for those needing enhanced vitamin D intake due to limited sun exposure or absorption challenges. ## Description High-potency, 5,000 IUThe role of vitamin D in calcium metabolism and bone health is well known.* Adequate amounts of vitamin D, an essential, fat-soluble vitamin, come from consistent exposure to sunshine and are difficult to obtain from dietary sources. Postmenopausal women, older individuals, and those with malabsorption, limited sun exposure may need higher intakes of vitamin D. Vitamin D3, the naturally occurring form, is supplied in high-potency amounts for those needing to conveniently augment dietary intake.Three Brands Become OneSince 1969, Klaire Labs® has been dedicated to developing clean, efficacious nutritional supplements to ensure optimal outcomes for even the most sensitive individuals. This enduring commitment to quality is at the root of the unification with sister brands ProThera and Complementary Prescriptions. These three brands have unified with a modernized look based on the legacy Klaire Labs® logo. Review: Reliable product - I appreciate that this is a physician therapeutic quality item.

I appreciate that it is available in 5,000 IU form (so that I don't have to take a bunch of lower dose pills in order to get this therapeutic dosage). ### ⭐⭐⭐⭐⭐ Great product good quality! *by S***L on February 1, 2026* Got my vitamin d up extremely fast on one use and I was very deficient ### ⭐⭐⭐⭐⭐ Effective product. Amazon not the cheapest source. *by C***L on July 22, 2020* This product was recommended by my Dr. I usually buy it at his office. If I run out between visits I buy it at Amazon. Must say the Dr office sells it for a significantly cheaper price. My Vit D levels have reached normal on this product. ## Frequently Bought Together - Klaire Labs Vitamin D3 5000 IU - High Potency Vitamin D 125mcg - Immune Support - Helps Promote Bone & Heart Health - Hypoallergenic (100 Capsules) - Klaire Labs SFI Health Magnesium Glycinate Complex - Bioavailable, Chelated Magnesium Supplement for Sensitive Individuals - Hypoallergenic Magnesium Capsules to Support Healthy Nerves (100 Capsules) - Klaire Labs SFI Health Magnesium Citrate - Readily Soluble Magnesium Supplement for Women & Men - 150mg Magnesium Citrate Capsules - Support Healthy Relaxation & Bone Health (90 Capsules) --- ## 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.hr/products/31678316-klaire-labs-sfi-health-vitamin-d3-5000-iu-high-potency](https://www.desertcart.hr/products/31678316-klaire-labs-sfi-health-vitamin-d3-5000-iu-high-potency) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-16*
