AURORA, Colorado, August 20, 2026 — Arthritis and related joint conditions affect an estimated 54 million U.S. adults, according to the CDC, making musculoskeletal disorders a primary driver of disability in aging populations. Zenith Labs has announced the commercial launch of Joint N-11, a ten-ingredient joint support capsule supplement formulated by Dr. Ryan Shelton, NMD, Director of Research at Zenith Labs. The formula is centered on Niacinamide — a form of Vitamin B3 that was examined in a 1996 randomized controlled pilot trial published in Inflammation Research in relation to joint mobility and inflammatory markers in adult subjects with osteoarthritis — supplemented by nine ingredients cited in published literature for anti-inflammatory, antioxidant, or connective tissue-related study findings.

Joint N-11 is manufactured in an FDA-inspected, GMP-certified facility in the United States and is available at freedomfromjointpain.net. The supplement is taken as two capsules daily with water. All ten active ingredients are individually identified on the product’s Supplement Facts panel. The manufacturer states the formula is free from gluten, dairy, nuts, egg, and crustaceans, and free of GMOs and BPAs.

Product Overview

This press release reports the commercial entry of Joint N-11 into the U.S. joint health supplement market. Joint N-11 is a dietary supplement developed and marketed by Zenith Labs, a dietary supplement company based in Aurora, Colorado, operating under the direction of Dr. Ryan Shelton, NMD, Director of Research. The manufacturer has structured the formula around Niacinamide as its primary active ingredient, citing the 1996 Jonas randomized controlled pilot trial as the evidence basis for that selection, supplemented by nine additional compounds.

Important note on research and product claims: The scientific citations referenced in this press release describe independent research on individual ingredient compounds conducted in separate laboratory or clinical settings under conditions unaffiliated with Zenith Labs. These studies examined the cited compounds in isolation or in specific formulations distinct from Joint N-11. The presence of an ingredient in Joint N-11 does not imply that the product will produce outcomes equivalent to or consistent with those reported in the cited studies. No clinical trial has evaluated the complete Joint N-11 formulation as a finished product. Zenith Labs does not claim that Joint N-11 produces the outcomes described in any cited study.

The manufacturer states that Joint N-11 is produced in an FDA-inspected, GMP-certified facility in the United States. Under 21 CFR Part 111, dietary supplement manufacturers registered with the FDA are required to comply with current Good Manufacturing Practice regulations governing production standards, ingredient testing, quality control, and product labeling.

“Joint N-11 was formulated around Niacinamide because it carries a specific and replicated clinical research record in osteoarthritis. The 1996 Jonas pilot randomized controlled trial in Inflammation Research examined Niacinamide against placebo in adult subjects with osteoarthritis in relation to joint mobility and inflammatory markers. The remaining nine ingredients were each selected based on published literature examining distinct anti-inflammatory, antioxidant, or structural support mechanisms in joint tissue. These are independent studies conducted under conditions unaffiliated with Zenith Labs. Joint N-11 has not been evaluated in a clinical trial as a finished product, and no equivalence to any cited study outcome is claimed.”

Ingredient Overview

The following section describes the ten disclosed ingredients of Joint N-11. Each ingredient has been cited in independent published research examining its properties in laboratory or clinical settings. All cited research was conducted under conditions unaffiliated with Zenith Labs and describes findings specific to the compound as studied — not to Joint N-11 as a finished product. No equivalence between cited study outcomes and Joint N-11’s effects is claimed or implied.

Niacinamide (Vitamin B3). Niacinamide is the primary active ingredient, included on the basis of a 1996 randomized controlled pilot trial published in Inflammation Research (Jonas et al.) that examined Niacinamide against placebo in adult subjects with osteoarthritis in relation to joint mobility, inflammatory markers, and anti-inflammatory medication usage.

Turmeric Root (Curcuma longa). Turmeric Root extract has been examined in a 2014 clinical study published in Clinical Interventions in Aging (Kuptniratsaikul et al.) in relation to pain and functional outcomes in adult subjects with knee osteoarthritis, compared to ibuprofen.

Ginger Root (Zingiber officinale). Ginger Root has been examined in a randomized double-blind placebo-controlled study published in the Indian Journal of Physiological Pharmacology (Paramdeep, 2013) in relation to pain and functional outcomes in adult subjects with knee osteoarthritis.

MSM (Methylsulfonylmethane). MSM has been examined in a 2011 randomized controlled study published in BMC Complementary and Alternative Medicine (Debbi et al.) in relation to pain, physical function, and quality of life outcomes in adult subjects with knee osteoarthritis.

L-Cysteine. L-Cysteine has been examined in a 2017 pilot study published in Cartilage (Simsek Ozek et al.) in relation to joint function and tissue outcomes in adult subjects with knee osteoarthritis.

Boswellia Serrata. Boswellia Serrata extract has been examined in a randomized double-blind placebo-controlled trial published in Phytomedicine (Kimmatkar et al., 2003) in relation to pain, joint mobility, and physical function outcomes in adult subjects with knee osteoarthritis.

Holy Basil (Ocimum tenuiflorum). Holy Basil phytonutrient content has been examined in a study published in Food Chemistry (Tohge et al., 2015) in relation to anti-inflammatory and antioxidant activity.

Rosemary Leaf (Rosmarinus officinalis). Rosemary and related botanical antioxidant compounds have been examined in a review published in Toxicology and Industrial Health (Ghasemzadeh Rahbardar & Hosseinzadeh, 2014) in relation to anti-inflammatory and tissue-protective properties.

Soy Lecithin. Joint lubrication-related supplementation was examined in a study published in the Nutrition Journal (Crowley et al., 2009) in relation to joint function outcomes in adult subjects.

BioPerine® (Black Pepper Extract). Piperine’s mechanism of action in enhancing nutrient bioavailability was examined in a review published in Critical Reviews in Food Science and Nutrition (Meghwal & Goswami, 2013).
