## Questions & Answers

**Q: How long does the bottom last? One month, etc?**
A: How long it lasts depends on the size of the bottle and your daily dose. Source Naturals makes a 4oz, 2oz, and 1oz bottle. Note that the 3oz option on Amazon is a typo. It's actually the 4oz bottle (they show the 4oz supplement facts when you select the 3oz option).4oz bottle: If you take 1 serving per day = 5 drops = 2,000 IU per day. Will last 739 days, or about 2 years.4oz bottle: If you take 2 servings per day = 10 drops = 4,000 IU per day. Will last 369 days, or about 1 year.2oz bottle: If you take 1 serving per day = 5 drops = 2,000 IU per day. Will last 369 days, or about 1 year.2oz bottle: If you take 2 servings per day = 10 drops = 4,000 IU per day. Will last 184 days, or about 6 months.1oz bottle: If you take 1 serving per day = 5 drops = 2,000 IU per day. Will last 184 days, or about 6 months.1oz bottle: If you take 2 servings per day = 10 drops = 4,000 IU per day. Will last 92 days, or about 3 months.

**Q: concentration of d3ius per drop**
A: 400 IUs per drop. Recommended daily serving size is 5 drops = 2000 IUs.

**Q: How long do I have to use this to begin to feel results?**
A: Not sure how long it takes to feel results because it depends on the dose you need.  For me, results took about a week. Taken after a meal seemed to work best.

**Q: does this drops contein polysorbate 80? Acording to one of the reviews it does. thanks!**
A: It doesn't list polysorbate 80 in the ingredients. So I don't think it does. You can always call the company and ask them to be 100% sure.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product, tastes good, mixes well in drinks
*by S***Y on November 28, 2025*

Great source of Vitamin C, pleasant taste in smoothies or drinks, adds sweetness.

### ⭐⭐⭐⭐⭐ Citrus Flavor is great
*by K***T on January 8, 2026*

Love the citrus flavor. I wish each drop was 2000 IU but double the amount of drops is fine for me with the citrus flavor. I have to take 10.000 IU a day because of an auto immune disease. I put the drops under my tongue for maximum absorption.

### ⭐⭐⭐⭐⭐ Nice product
*by F***J on April 5, 2017*

This is a nice product, it's easy to use the dropper, and it raised my vitamin D levels (which were low before I started taking it). I actually quite enjoy the taste of it (I mix it to smoothies, so I do not have it plain, but it adds to the taste of the smoothie or even if I am having orange juice or milk). One issue is the expiration date. For me it was around 6 months after I bought it (the 4 ounce bottle). However, no one can get through the 4 ounce bottle in this length of time. From the questions answered above: 4oz bottle: If you take 1 serving per day = 5 drops = 2,000 IU per day. Will last 739 days, or about 2 years. 4oz bottle: If you take 2 servings per day = 10 drops = 4,000 IU per day. Will last 369 days, or about 1 year. There is a strange answer from one of the sellers: There are approximately 739 servings in one bottle. With the suggested use of 5 drops a day, one bottle would last approximately 147 days. By Swanson Health Products SELLER on April 7, 2015 Actually, if there are 739 servings, with 5 drops/day, it should be 739 days, as the previous person pointed out. So be careful with how much you buy of this. To those of you that bought it, how far after the purchase date is the expiration?
