Overview
A plant based vitamin D3 liquid delivering 10,000 IU per serving in sublingual drop form, sized as a 1 fluid ounce bottle covering about 30 servings. Positioned as a vegan alternative to the lanolin sourced D3 most drops use.
Most vitamin D3 supplements are sourced from lanolin, which rules them out for strict vegans, so a plant based cholecalciferol source is the main thing distinguishing this product from typical D3 drops. Liquid drops also let you adjust the dose in a way capsules with a fixed amount don't, though 10,000 IU is a high daily strength worth checking against your own needs.
- 10,000 IU vegan vitamin D3
- Plant based cholecalciferol source
- Sublingual liquid drops
- Adjustable dosing, 30 servings
Who it's for
Fits vegans and plant based dieters who specifically need a non animal source of vitamin D3 and want adjustable dosing rather than a fixed capsule amount. The 10,000 IU strength is high, so anyone unsure how much D3 they need should check with a doctor before taking a full dropper daily.
Strengths and trade-offs
Drawn from this product's published specifications.
- Plant based, vegan cholecalciferol source
- Adjustable liquid dosing
- High 10,000 IU strength per serving
- Unflavored, sublingual format
- 10,000 IU is a high dose that isn't right for everyone without guidance
- 30 servings from a 1 fluid ounce bottle is a relatively short supply
Performance notes
Sublingual drops are absorbed under the tongue rather than through the digestive tract the way a capsule is, which is the appeal for people who want faster or more direct absorption. Because it's a liquid, the dose can be adjusted lower than the full dropper amount, something a fixed capsule strength doesn't allow.
