- About this item
- ENDUR-B COMPLEX SUSTAINED RELEASE – Each tablet contains 8 essential B vitamins. Yet unlike fat-soluble vitamins, water-soluble B vitamins are not stored in body tissues and require daily replenishment.*

- 5-7 HOUR SUSTAINED RELEASE: Endurance Products Company’s sustained-release tablet technology slowly releases nutrients over 5-7 hours, mimicking how your body processes food for optimal absorption and maximum effectiveness. This minimizes side effects and digestive upset.*
- FREE OF COMMON ALLERGENS: Vegan/Vegetarian safe. No milk, egg, fish, shellfish, tree nuts, peanuts, wheat, corn, yeast, or soy. Gluten-free. No salt, sugar, starch, artificial flavorings, or preservatives.

### ⭐⭐⭐⭐⭐ 







  
  
    Great Product
  

*by E***I on Reviewed in the United States on May 4, 2021*

For years I was ordering all my ENDUR supplements off of the ENDUR website and paying a FORTUNE for shipping. With my Amazon Prime Membership I get FREE SHIPPING which means I get the ENDUR products CHEAPER from Amazon than I get them from ENDUR. That's Crazy.

### ⭐⭐⭐⭐⭐ 







  
  
    Time release vitamins just make sense
  

*by C***L on Reviewed in the United States on June 29, 2020*

My husband & I have taken Endurance Products vitamins for the past 30 years.  It is difficult to say how the B complex has improved my health but it certainly hasn't done any harm.  I am a very healthy 75 yr old and my husband is 81.  The time release factor is good since it is more like the vitamins you get in your food.

### ⭐⭐⭐⭐⭐ 







  
  
    Great price and great product
  

*by S***E on Reviewed in the United States on March 4, 2021*

I have been taking this years. I would highly recommend it. Purchasing on Amazon I save a lot of money.
