Jigsaw Activated B w/SRT®

Sustained Energy, All Day Long.*

Jigsaw Activated B w/SRT® utilizes only the active B vitamin forms in a timed-release formula to fuel your body all day long. Your body uses B-vitamins in every cell in your body, every second of the day and night. Since they are water-soluble, your body cannot store B-vitamins and you must have a constant supply to keep your body systems functioning properly -- especially to maintain healthy energy levels.*

Our Quality Promise

We deliver only the highest quality nutritional supplements. Every batch of our products is triple-tested, and the 3rd party lab results are posted online for all to see. We believe that what’s on the label is what should be in the bottle, and nothing else.

Lightbulb with a question mark in it.

When it comes to B-vitamins, form matters.

Inactive, cheap forms of B-vitamins have poor absorption and require conversion by the liver before they can be used by the body — meaning most of them are quickly eliminated from your body before offering many benefits. Activated B w/SRT only utilizes the active, most absorbable forms, maximizing the health benefits.*

Why is Activated B w/SRT® better?

  • Only utilizes active B-vitamins for better absorption.*
  • Easy on the liver because these are B-vitamins in their active (and frankly, more expensive) form.*
  • Includes a proprietary Sustained Release Technology (SRT) to provide you a steady balance of B-vitamins throughout the day.*
  • 3rd party label claim verified.
  • 100% Money-Back Guarantee.

What can Activated B w/SRT® help me with?

  • Maintain healthy energy levels throughout the day.*
  • Promote mental alertness, concentration, and memory.*
  • Maintain proper functioning of the heart, the nervous system, and the digestive system.*
  • Support the body's ability to detoxify itself.*
  • Support a balanced response to stress.*
  • Support healthy hormonal balance.*
  • Maintain adequate levels of vitamin B12—especially helpful if you're an older adult or a strict vegetarian.

See how it works

Finally an all-methylated product!!! I've looked at so many B-complex products over the years, but could never find one that didn't have folic acid or cyanocobalamin. This product replaces the seven individual B vitamins I'd been taking and gives me the four others I'd been missing since switching from a multiple vitamin. - CB

I’ve been taking it for about a month and I’ve noticed that my energy level is up and I feel better. I’m sure that the longer I take it, I’ll notice more of its benefits. I can already tell that the Sustained Release Technology is a major benefit. It seems to allow my body to absorb the B vitamins more efficiently. When I’ve taken other B vitamins without SRT, more of the vitamins are eliminated in my urine. Jigsaw Activated B w/SRT is noticeably less. - Jim C

Patrick Sullivan Jr. - CEO Jigsaw Health

Hi there,
I’m Patrick Sullivan Jr.

My dad and I started Jigsaw Health in 2005. My dad struggled with various health challenges for 30+ years —fatigue, trouble sleeping, and gastrointestinal problems, to name but a few…

“Figuring out causes of my own health problems always felt like solving a puzzle. Thus, the company name, Jigsaw Health.”

It’s discouraging...


to always feel bad and not know why; to go to doctors and be told there is nothing wrong with you when you know there is. It’s not supposed to be that way!

At Jigsaw Health, we’ll help you find your health answers. We promise you, there is hope.

We out-hug the competition

While every company claims to have the best customer service, most companies just want you to be loyal to them. Jigsaw Health does the opposite and strives to be a loyal friend to you.

Need a friendly voice? Call us at 1-888-352-5050.

There’s a hug coming your way. :)
