Compare Ultra Vitamin D 2000IU and 1000IU tablets on strength, supply length, and price per tablet to decide which daily vitamin D dose fits your routine.
Quick answer
Choose Ultra Vitamin D 2000IU if you want a higher-strength daily tablet and are comfortable with 2000 IU per day; choose Ultra Vitamin D 1000IU if you prefer a lower daily dose or want the lowest upfront cost. Both come in 96-tablet bottles and are formulated for adults 50+.
What actually differs between the two tablets
The main difference is the amount of vitamin D3 per tablet: 2000 IU versus 1000 IU. Both are once-daily tablets, both are gluten-free and suitable for vegetarians, and both are designed for adults 50+ and for men and women. The 2000IU bottle also carries a higher catalog price (USD 6.26 vs USD 3.69), but it delivers twice the strength per tablet.
Because both bottles contain 96 tablets, the supply length is the same when you take one tablet daily: about three months. The real choice is whether you want 2000 IU or 1000 IU in each daily dose, not how long the bottle lasts.
The trade-off: strength versus upfront cost
Ultra Vitamin D 2000IU gives you a higher dose in a single tablet, which may suit you if you and your clinician have decided that 2000 IU daily is appropriate. The trade-off is a higher price per bottle and a higher cost per tablet than the 1000IU option.
Ultra Vitamin D 1000IU costs less per bottle and provides a moderate daily dose. If you prefer to keep your daily vitamin D intake at 1000 IU, or if you simply want the lowest upfront spend, this is the more economical choice. Neither product is positioned as a replacement for prescribed high-dose vitamin D, and the catalog does not state suitability for children or pregnancy, so check with a healthcare professional if those apply.
When the price difference matters less than the dose
If you have been advised to take 2000 IU daily, buying the 2000IU tablets avoids taking two 1000IU tablets each day. That convenience can matter if you already manage several daily supplements. Conversely, if you only need 1000 IU, the 1000IU bottle avoids paying for extra strength you do not need.
The catalog does not specify a maximum daily intake or upper limit for these products. Do not stack them with other vitamin D supplements without checking the total amount with a pharmacist or doctor.
Decision rules for choosing your strength
- If you have been advised to take 2000 IU daily: Choose Ultra Vitamin D 2000IU so one tablet covers your daily target without doubling up on 1000IU tablets. Check the total vitamin D in any other supplements you take before adding this.
- If you prefer a moderate 1000 IU daily dose: Choose Ultra Vitamin D 1000IU for a lower-strength once-daily tablet and a lower upfront cost. If you later need 2000 IU, you would need two tablets daily, which changes the cost per day.
- If upfront cost is your main concern: The 1000IU bottle has the lower catalog price (USD 3.69 vs USD 6.26), but each tablet contains half the vitamin D. Compare cost per 1000 IU, not just bottle price, to see the real difference.
