CHK Nutrition

What CHK Nutrition does

CHK Nutrition is a privately held, Minnesota-based nutraceutical manufacturer founded in 2005 by medical doctors, with research roots dating to 1995. The company designs and distributes a tightly curated line of amino acid supplements — anchored by NeuroReplete LT (a balanced 5-HTP/L-Tyrosine formula supporting serotonin and catecholamine production) and CysReplete LT (cysteine plus selenium for glutathione support) — alongside complementary products such as Mucuna 40%, Tyrosine Powder, RepleteExtra LT, and Vitamin B-6. Formulations are differentiated by an underlying scientific rationale that the Aromatic Amino Acid Decarboxylase enzyme pathway links serotonin and catecholamine synthesis, requiring balanced precursor administration to avoid inadvertent neurotransmitter depletion; every batch is verified through a five-tier raw, in-process, finished, independent third-party (NSF), and stability testing protocol.

The company sells exclusively to licensed healthcare professionals through account-verified, order-via-phone/online relationships, with drop-ship fulfillment directly to patients under a provider's active care. Pricing is unit-based ($8.75 for Vitamin B-6 up to $222.35 for Mucuna Powder 270g), with a 10% volume credit on accounts exceeding $3,000 in a calendar month; free domestic shipping kicks in above $300 and international orders are accepted at cost. CHK Nutrition also acts as the distribution partner for NeuroResearch and Hinz Medical Foods' medical food line, and operates a supporting patient-direct channel through pdsupplements.com.

Its customer base is fragmented across individual clinicians, with testimonials spanning CA, TX, NE, WI and other U.S. states, plus international reach. In 2010-2011, CHK Nutrition resolved an FDA matter concerning promotional claim boundaries without any product-safety findings, and has since maintained compliance through external FDA counsel review of all external communications. The business remains founder/physician-owned with no disclosed institutional capital, no M&A activity, and headcount in the 11-50 range operating from a single Cotton, Minnesota headquarters and warehouse.

Core offering

CHK Nutrition designs, manufactures, and distributes balanced amino acid nutritional supplements—anchored by NeuroReplete LT™ and CysReplete LT™—that support healthy, normal levels of serotonin, dopamine, norepinephrine, and epinephrine. The line also includes Mucuna 40% capsules and powder, RepleteExtra LT™, Tyrosine Powder, Vitamin B-6, R & R amino acid products, and precision digital scales, and the company distributes Hinz Medical Foods/NeuroResearch medical foods. All products are sold exclusively through licensed healthcare professionals via account-based ordering, with drop shipping offered directly to patients.

Product overview

CHK Nutrition offers a portfolio of scientifically researched amino acid nutritional supplements designed to support normal brain, gut, and overall health through balanced neurotransmitter support. The core product line centers on two flagship formulations — NeuroReplete LT™ (supporting serotonin, dopamine, norepinephrine, and epinephrine through balanced 5-HTP and L-Tyrosine) and CysReplete LT™ (supporting glutathione via cysteine and selenium for sulfur replenishment). These are complemented by targeted add-on amino acid products including Mucuna 40% capsules and powder (natural L-dopa from Mucuna pruriens), RepleteExtra LT™ (additional 5-HTP and L-Tyrosine without co-factors), and Tyrosine Powder — all intended to be used under healthcare professional guidance alongside the core formulations. A Vitamin B-6 (100 mg) supplement and two digital scales (Cesto and Vera) support dosing accuracy for powder products. Additionally, CHK Nutrition distributes Hinz Medical Foods medical food products (including Mucuna Pruriens Powder) for NeuroResearch. The R & R (Replete & Restore) and R & R SANS products round out the amino acid line. All products are sold exclusively through licensed healthcare providers, not to the general public.

Scale indicators5 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Designs for Health: Major practitioner-grade supplement brand with strong clinical education focus and an amino acid/neurotransmitter product line. Uses the same professional-channel-only distribution model and competes for provider mindshare in mood, sleep, and cognitive support categories.
• Thorne: Premium practitioner and direct-to-consumer supplement brand with NSF-certified manufacturing and a deep neurotransmitter/brain health portfolio. Competes with CHK in the practitioner channel while also reaching consumers directly, representing a broader and better-capitalized competitor.
• Pure Encapsulations: One of the largest practitioner-exclusive supplement brands, offering broad categories including amino acids, neurotransmitters, and cognitive support sold exclusively through healthcare professionals. Larger and broader portfolio than CHK but competes directly for the same provider prescribing decisions on brain/mood support.
• Douglas Laboratories: Practitioner-grade nutritional supplement brand with deep amino acid and neurotransmitter support offering. Sells exclusively through healthcare professionals with focused provider education, similar to CHK's GTM.
• Metagenics: Large functional medicine-focused supplement manufacturer with practitioner distribution and a portfolio spanning amino acids, cognitive health, and medical foods. Represents a scaled competitor targeting the same provider customer base.

Emerging players

• Seeking Health: Smaller practitioner-oriented supplement brand focused on methylation, neurotransmitter, and amino acid support with practitioner and direct sales. Overlaps with CHK on neurotransmitter precursor formulations and provider-only positioning but reaches smaller scale.
• Life Extension: Large supplement brand with extensive neurotransmitter, mood, and cognitive health SKUs. Primarily sells direct-to-consumer and through healthcare professionals, competing for patient and provider demand in the same brain-health category as CHK.

Direct peers

• NeuroResearch: Developer of the medical food products that CHK Nutrition distributes on its behalf, NeuroResearch operates in the same neurotransmitter-focused nutritional supplement space and shares the practitioner-channel go-to-market. The two are operationally intertwined via a co-distribution relationship, making NeuroResearch the closest functional peer.
• Xymogen: Practitioner-exclusive supplement brand offering neurotransmitter and amino acid support formulations sold through licensed healthcare providers. Closely mirrors CHK's professional-channel distribution and brain/mood product positioning.
• Hinz Medical Foods: Brand owner of the medical food line distributed by CHK Nutrition. Operates in the same practitioner-grade medical food category targeting neurotransmitter and brain health support through amino acid formulations. Direct distribution partner to CHK and adjacent competitor in provider-only distribution.
