ENDUR-B® Complex SR

1. What it is

A high-potency complex containing all 8 essential B vitamins, designed to gradually release nutrients over 5 to 7 hours for optimal absorption and tissue retention.*

2. Ideal for

Active adults, fitness enthusiasts, health-conscious individuals over 40, and anyone prioritizing cardiovascular wellness who wants to maintain optimal B vitamin levels to supportpeak performance and healthy aging.*

3. How to take it

As a dietary supplement for adults, take one (1) tablet daily with a full glass of water, preferably with a meal.

4. Bonus benefits

B vitamins play a vital role in many functions, including energy metabolism and supporting cardiovascular health by maintaining homocysteine levels already in the normal range.*

5. If you really like science

The sustained-release delivery system allows B vitamins to be absorbed gradually, promoting optimal tissue retention. Vitamins B6, folic acid, and B12 are particularly important for heart health, assisting in maintaining healthy homocysteine levels. Homocysteine is an amino acid that the body produces when it breaks down protein. It's a normal part of metabolism. Maintaining a blood level of homocysteine in the normal range is associated with cardiovascular health.  Healthy levels of homocysteine are often maintained through the intake of certain B vitamins, such as B6, B12, and folic acid, which help convert homocysteine into other substances the body can use. In addition, optimal levels of these vitamins contribute to cellular function across various systems, including the brain, nervous system, and immune system (1).*

6. Inactive ingredients

Calcium phosphate, vegetable wax (rice bran and/or carnauba), stearic acid (vegetable), magnesium stearate (vegetable), modified cellulose, and silica.

7. Precautions

Consult your healthcare professional prior to use if you have or suspect a medical condition, are taking any medications, or are nursing or pregnant. As with all dietary supplements, keep out of reach of children.

8. Product Quality Control Tests Performed

ENDUR-B® Complex SR is manufactured in the United States (Oregon) in a state-of-the-art, FDA-registered facility that meets or exceeds current Good Manufacturing Practices (cGMP). Quality control tests are performed at every stage of the manufacturing process from rigorous raw material testing to finished product testing.

Endurance Vitamin B Sustain Release

I am a firm believer in Endurance Supplements. I chose Their B formula because #1 it is Sustained Release. #2 I agree with Endurances formulation of the B ingredients.. When you look at other companies formulas they often have way too high levels of various B levels. What i do want a higher level of is B3 Niacidimide

ENDUR-B Complex SR

These are good; however, the ENDUR-B Complex SR with Iron are great! Both are products I use daily and would recommend.
