The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.
Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.
Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.
Helps Support Immune, Bone and Cardiovascular Health
Doctor's Best Vitamin D3 provides D3 (as cholecalciferol) needed for the body to regulate phosphorus and calcium levels for healthy bones, teeth and heart. Vitamin D3 is produced in the skin by absorbing the sun's UV rays and is obtained from food in limited amounts. Sun protection and climate factors may influence low Vitamin D3 levels. Vitamin D3 is beneficial for immune, cardiovascular, bone density and structure, and cellular function. It plays a role in most organs and systems of the body and influences the chemical messengers of the immune systems.
Adult Use: Take 1 softgel daily with food, or as recommended by a nutritionally-informed physician.
Extra virgin olive oil, softgel capsule (bovine gelatin, glycerin, purified water).
Store in a cool dry place.

The recent research emphasis on the role of D3 supplementation has made this an essential part of my supplementation program. I would not want to be without my D3 even in the summer time when the sun is at its highest as I am a senior and have learned that my ability to convert sunshine to vitamin D has decreased over the years. Also, my dermatologist is constantly warning against sun exposure.

Very small so easy to take. Not as good as a spray that absorbs through the mouth / cheek but still good. Knocked off 1 star since the capsule is animal based which there is no need for these days since plant based capsules can be made.

I take 3-4 Vit D3 softgels per day and I want to continue doing so because I do not get that much sun. I believe it is doing what it promises.
