PSSMFLex - Veterinary Reference Extract

EquiNatural® | Botanical NuBotanical & Nutritional Support for Muscle Function, Energy Metabolism & Tension Regulation

Organically grown • Human grade • Not veterinary medicine

1. Important Context for Veterinary Review

Equine muscle dysfunction, particularly in horses with PSSM (Polysaccharide Storage Myopathy) or PSSM-type patterns, is characterised by impaired energy utilisation within skeletal muscle.

Rather than a primary structural issue, the underlying challenge is often:

  • altered muscle energy metabolism
  • inefficient utilisation of fatty acids and glycogen
  • increased muscle fibre tension and contracture
  • reduced capacity for relaxation following contraction
  • delayed recovery and increased susceptibility to stiffness or tying-up

Clinical presentation may include:

  • stiffness, particularly on initial movement
  • prolonged warm-up time
  • restricted stride length or “holding” through the body
  • exercise intolerance or fatigue
  • recurrent muscle soreness or tying-up episodes
  • improvement with consistent work and decline with rest

PSSMFlex is not a joint or analgesic formulation.
It is designed to support muscle function at a metabolic and cellular level, addressing energy use, contraction–relaxation dynamics, and recovery.Veterinary oversight is recommended in cases of diagnosed myopathy, recurrent tying-up, or metabolic disease.


Functional Positioning - PSSMFlex

PSSMFlex occupies the muscle-function tier within EquiNatural’s movement and performance pathway:

PSSMFlex → JointReflexa / DuoBute → Systemic layers (KPUCOMBO / mineral support)

Where:

  • PSSMFlex supports muscle metabolism, tension regulation, and recovery
  • JointReflexa / DuoBute support structural comfort and tissue-level strain
  • KPUCOMBO / mineral support address deeper metabolic or systemic contributors

PSSMFlex is intended to:

  • support efficient muscle energy production
  • assist muscle fibre relaxation and reduce tension patterns
  • support post-exercise recovery and resilience
  • improve consistency of movement where restriction is muscular in origin

It is not designed for joint pathology or acute injury management.


Core Actions

  • Supports mitochondrial energy production in muscle cells
  • Assists utilisation of fatty acids for efficient fuel
  • Supports muscle fibre relaxation and reduces tension
  • Contributes to improved movement fluidity and consistency
  • Supports recovery following exercise or metabolic strain
  • Maintains muscle tissue resilience in susceptible horses


2. Product Summary

PSSMFlex is a targeted amino acid and botanical blend designed for horses experiencing:

  • muscle stiffness or tightness
  • PSSM or PSSM-type movement patterns
  • exercise intolerance or reduced stamina
  • prolonged warm-up or restricted movement
  • post-exercise soreness linked to muscle metabolism

It is used as a daily foundational support for muscle function, particularly where movement restriction is muscular rather than structural.


3. Clinical Rationale (Nutritional Mechanisms of Action)

1. Muscle Energy Production & Metabolism

Acetyl L-Carnitine

  • facilitates transport of fatty acids into mitochondria
  • supports efficient ATP production within muscle cells
  • contributes to improved stamina and reduced fatigue

2. Muscle Fibre Relaxation & Tension Regulation

Viburnum opulus (Cramp Bark)

  • supports smooth and skeletal muscle relaxation
  • assists reduction of involuntary contraction and rigidity
  • contributes to improved movement fluidity

3. Muscle Repair & Tissue Resilience

L-Glutamine

  • supports muscle protein synthesis and repair
  • contributes to recovery following exertion
  • supports cellular resilience under metabolic stress

PSSMFlex does not diagnose, treat, or prevent disease.  It provides nutritional support for muscle metabolism and function.


4. Nutritional Indications (Non-Diagnostic)

May be considered nutritionally in horses showing:

  • stiffness or tightness on movement
  • prolonged warm-up or restricted stride
  • muscle-based movement limitation
  • exercise intolerance or fatigue
  • history of tying-up or muscle soreness
  • PSSM or PSSM-type metabolic patterns

Not intended for:

  • primary joint pathology
  • acute injury or trauma
  • lameness requiring diagnostic investigation
  • neurological causes of movement restriction


5. Composition (No Ratios Listed)

 L-Glutamine
 Acetyl L-Carnitine
 Viburnum opulus (Cramp Bark)

Delivered as a powdered blend for daily use.


6. Compound Micro-Monographs (Technical)

L-Glutamine
Primary amino acid in skeletal muscle; supports repair, recovery, and cellular resilience.

Acetyl L-Carnitine
Supports mitochondrial energy metabolism and fatty acid utilisation in muscle tissue.

Viburnum opulus (Cramp Bark)
Antispasmodic botanical supporting muscle relaxation and tension release.

7. Medication Considerations

Use under veterinary oversight with:

  • Muscle-related medications or metabolic therapies
    → may complement but should be coordinated with veterinary plan.
  • Sedatives or muscle relaxants
    → potential additive effects with Viburnum.
  • Cardiovascular conditions
    → monitor due to indirect effects on muscle and circulation.
  • Bleeding disorders
    → exercise caution due to botanical components.

No harmful interactions are known at nutritional levels; considerations relate to muscle physiology and systemic balance.


8. Feeding Guidance

Daily Feeding Rate

5g per 100kg bodyweight daily (25g for a 500kg horse).
1 × 15ml scoop ≈ 10g.

Introduce gradually over 5–7 days.

For best results:

  • combine with appropriate diet and mineral balance
  • ensure consistent exercise and routine
  • integrate into a structured management plan

Suitable for long-term use.


9. Clinical Considerations

Advisories

  • Designed to complement appropriate diet, minerals, and movement management.
  • Best used as part of a consistent daily routine.
  • Monitor changes in suppleness, movement quality, and recovery.
  • May be combined with structural or comfort support where needed.

Contraindications

  • Pregnancy or lactation (due to Viburnum opulus).
  • Use with caution in horses with cardiovascular concerns or bleeding disorders.
  • Seek veterinary guidance where significant metabolic disease is present.


10. Supporting Products

  • DuoBute — daily comfort support
  • TriBute — acute-phase support
  • KPUCOMBO — deeper metabolic patterns
