Thorne Vitamin D Liquid is a liquid vitamin D3 supplement that delivers easy, accurate, and personalized dosing to support healthy bones, immune function, and cardiovascular health. Each drop provides cholecalciferol (vitamin D3) in a base of medium-chain triglyceride oil, making daily supplementation simple for adults and children across all stages of life.

Why This Supplement Works

Vitamin D3 (cholecalciferol) is a more potent and better absorbed form than vitamin D2, and research shows it is more effective at raising overall vitamin D levels. Vitamin D, often called the sunshine vitamin, is produced by the skin during sun exposure, yet sunscreen use, indoor lifestyles, seasonal changes, and clothing choices can leave many people short. A daily liquid vitamin D supplement offers a convenient, adjustable way to support healthy levels. The liquid format also absorbs easily and lets you fine-tune your dose drop by drop.

Key Nutrients

• Vitamin D3 (as cholecalciferol): 1,000 IU (25 mcg) per 2 drops, supporting healthy bones, muscles, and immune function

• Medium-chain triglyceride oil base: provides a fat carrier that supports absorption of this fat-soluble vitamin

• Mixed tocopherols (natural vitamin E): preserve freshness without synthetic additives

• Free from gluten, dairy, soy oil, and sesame oil for a clean, allergen-conscious formula

How to Take

1. Invert the bottle to dispense individual drops; the self-dispensing top meters one drop at a time.

2. Take 2 drops one to three times daily, or as recommended by your healthcare provider.

3. Place the drops directly into the mouth, or mix into food or a beverage. Pairing with a meal that contains some fat can support absorption.

4. Store tightly sealed in a cool, dry place and do not refrigerate.

Who It's For

This liquid vitamin D supports adults and children who want flexible, customizable dosing without swallowing pills or capsules. It may be especially helpful for those with limited sun exposure, predominantly indoor routines, darker skin tones, or regular sunscreen use, all common factors that can contribute to lower vitamin D levels. Backed by Thorne's third-party testing and trusted by healthcare practitioners, it is a clean choice for everyday wellness. As with any supplement, consult your healthcare provider before starting, particularly if you are pregnant, nursing, or taking other medications.
