Overview
MaryRuth's Megadose Vitamin D3 is a liposomal liquid delivering 4000 IU of vitamin D3 alongside vitamin B12, in a mixed berry flavored 7.6 fl oz bottle sized for 45 servings.
Liposomal delivery wraps the vitamin D in a lipid layer, an approach some liquid supplements use to aid absorption compared to a plain oil-based drop. At 4000 IU per serving, this dose sits well above the commonly cited baseline daily amount, positioning it as a megadose rather than a standard maintenance level. B12 is included alongside the D3 rather than sold separately.
- 4000 IU liposomal vitamin D3 per serving
- Includes vitamin B12
- Mixed berry, 7.6 fl oz, 45 servings
- Vegan, sugar free, non-GMO
Who it's for
Fits adults wanting a higher-dose liquid vitamin D3 with B12 included, in a vegan, sugar free liquid format rather than a tablet or softgel. Not intended for children, given the 4000 IU megadose framing.
Strengths and trade-offs
Drawn from this product's published specifications.
- 4000 IU vitamin D3 per serving
- Liposomal format for absorption
- Includes vitamin B12
- Vegan, sugar free, gluten free, non-GMO
- High 4000 IU dose, not for casual maintenance

Performance notes
The liposomal format is meant to improve how the body absorbs vitamin D3 compared to a plain liquid drop, and pairing it with B12 covers two commonly paired nutrients in one serving. At 45 servings per 7.6 fl oz bottle, each serving is a small measured amount rather than a full dropper.
