Curcumin-SR™ unleashes the power of curcumin with MicroCurcumin™, an innovative curcumin formulation with 10x greater bioavailability than regular curcumin to enhance joint health and comfort, decrease oxidative stress, and promote healthy inflammation response.*
Melatonin-SR™ features MicroActive® Melatonin and is released gradually over 7 hours. A quick, initial release of 40% at bedtime is followed by a slow, gradual release of the remaining 60% over the course of the night. This supplement helps reduce nighttime and early morning waking, leading to more restorative rest.*
Citrulline-SR features MicroActive® Citrulline, a special form that has reduced particle size for better absorption and releases citrulline slowly over 10 hours to keep blood levels steady. Citrulline helps your body make the amino acid L-arginine, which has benefits for cardiovascular health and athletic performance.*

Melatonin-SR™
I have had bouts of insomnia for decades. Everything I have tried previously didn't work for me. I alternate between all 3 issues, trouble falling asleep, waking several times and waking hours before I should and not being able to fall back asleep. I happened to find this formula and have had a good couple nights of sleep. THANK YOU!

our ingredients
MicroCurcumin™
Curcumin is the active constituent of turmeric, the bright yellow spice found in Indian curries and featured in the popular drink golden milk. Turmeric has long been used in Ayurveda, the ancient medicinal system of India, for a variety of health concerns.*
Made through a proprietary process, MicroCurcumin™ is more bioavailable than regular curcumin for two reasons. First, MicroCurcumin™ has a very small particle size that is easily able to pass through the luminal membrane of the small intestine. Second, MicroCurcumin™ is encased in a special sustained-release matrix that gradually releases the curcumin over 12 hours, allowing it to enter the bloodstream at a slow and steady pace.

L-Citrulline (MicroActive®)
L-citrulline is an amino acid found in many foods, including legumes, milk, fish, and meat. As a precursor to the amino acid L-arginine, it boosts the production of nitric oxide in the body.* Nitric oxide dilates your blood vessels, improving blood flow.* As a result, citrulline has benefits for cardiovascular health, athletic performance, and male sexual function.*
Made through a proprietary process, MicroActive® Citrulline is more bioavailable than regular citrulline for two reasons. First, MicroActive® Citrulline has a very small particle size of less than 10 microns, so it can easily pass through the luminal membrane of the small intestine. Second, MicroActive® Citrulline is encased in a special sustained-release matrix that gradually releases the citrulline over 10 hours, allowing it to stay in the bloodstream longer than regular citrulline (20 out of 24 hours at the 2-capsule daily dose).

MicroActive® Melatonin
Melatonin is the hormone your pineal gland secretes at night to prepare your body for sleep.* MicroActive® Melatonin supplies melatonin in a special, micronized, sustained-release matrix using patent-pending MicroActive® technology. This form of melatonin is released into the bloodstream in two discrete stages. A quick initial burst of 40% of the dose helps you fall asleep quickly.* The remaining 60% is released gradually over 7 hours to help you stay asleep until dawn.*
Sustained-release melatonin has been tested in kids, adults, and seniors and has been shown to reduce the time it takes to fall asleep, increase time spent asleep, and improve sleep quality and next-day alertness.* It can also help recalibrate your internal clock when you travel across time zones.*

Protectively
Packaged in the USA

Frequently Asked Questions
-
What solvent is used in the extraction of the curcumin used in Curcumin-SR™?
The curcumin used in our Curcumin-SR™ formula is an organic curcumin that is extracted with ethanol. For more information, please visit: www.realorganiccurcumin.com
-
How long does the curcumin in this product stay in your system?
MicroCurcumin™ provides a 12 hour multi-staged sustained release into the body.
-
Is it possible for the polymers in the formula to bio accumulate over time?
The polymers like HPMC are not absorbed by the system. HPMC is a soluble fiber that is also not fermentable by the colon bacteria. Beta cyclodextrin is also not absorbed from the stomach and small intestines. It can be broken down by the enzyme amylase to form open chain sugars and glucose. Carnuaba wax is highly insoluble and is not absorbed. So, all the polymers are eliminated from the GI tract, no chance of bioaccumulation.
-
How does this differ from other Citrulline products on the market?
Other citrulline products typically face two challenges: large particle size limits absorption, and quick release leads to a short presence in the bloodstream. Citrulline-SR addresses both by reducing particle size for enhanced absorption and providing a gradual ten-hour release, ensuring sustained availability in the bloodstream.
-
How long does Citrulline-SR stay in your system?
MicroActive L-Citrulline stays in your bloodstream for 12 hours — 3x longer than regular citrulline.
-
How long does the Melatonin stay in your system?
The MicroActive® Melatonin in our Melatonin-SR™ formula has been shown to offer 7 hours of sustained release.
-
How does this differ from other melatonin products on the market?
Unlike other Melatonin products, Melatonin-SR™ is released in two-stages: an initial rapid release to help you to fall asleep and then a slower sustained release to help you to stay asleep until morning.*
