Overview
Chromium picolinate is a trace metal nutraceutical that may be used as an adjunctive treatment for diabetes mellitus and obesity, particularly in cats.
- Clinical Efficacy: Its efficacy remains controversial in veterinary medicine, and it does not appear to be useful in dogs with diabetes mellitus.
- Biologic Forms: Trivalent chromium (Cr III) is the biologically active form found in supplements and food, which is distinct from the highly toxic and carcinogenic hexavalent chromium (Cr VI) used in industrial applications.
- Safety: Generally considered safe at recommended dosages, though its true clinical benefit requires individual patient trials.
Mechanism of action
Chromium is an active component of the glucose tolerance factor (GTF), a complex of molecules including glycine, glutamic acid, cysteine, and nicotinic acid.
While its exact role in carbohydrate and nitrogen metabolism is not fully elucidated, it is thought to enhance insulin receptor sensitivity and facilitate glucose transport into cells.
- GTF → Insulin Receptor Binding → Enhanced Intracellular Glucose Uptake
- It does not lower blood glucose levels in normal, healthy patients.
Safety & warnings
Contraindications
- Renal insufficiency (use with caution)
Adverse effects
- Cognitive, perceptual, and motor dysfunction (reported in humans receiving the picolinate salt)
Precautions
Renal Insufficiency: Chromium supplements could potentially exacerbate renal insufficiency; use with caution in these patients. Behavioral Alterations: Because the picolinate salt can potentially alter behavior, consider using chromium chloride or chromium nicotinate in patients receiving SSRIs or other behavioral therapies. Pregnancy: Use cautiously in pregnant animals, especially cats, as they may receive much higher dosages than human equivalents.
Drug interactions
May increase the urinary excretion of chromium
May decrease chromium levels by inhibiting their absorption; clinical significance is unclear
May increase the absorption and retention of chromium; clinical significance is unlikely
Theoretically, co-administration of zinc with chromium could decrease the oral absorption of both
Monitoring
- Fasting blood glucose
- Appetite and attitude
- Body condition and weight
- PU/PD resolution
- Serum fructosamine levels
- Glycosylated hemoglobin levels
Pharmacokinetics
Absorption
Poorly absorbed from the GI tract. When given as a salt (picolinate, chloride, nicotinate), lipophilicity and solubility are increased, enhancing absorption.
Elimination
Most of an oral dose is excreted in the feces. Absorbed chromium is eliminated via the kidneys.
Overdose
Little information on acute overdoses is available. In humans, there are case reports of women developing renal failure after taking excessive doses of chromium picolinate.

Client information
Give this supplement exactly as prescribed by your veterinarian.
- Consistency is Key: Do not change brands or formulations without your veterinarian's approval, as different products may be absorbed differently.
- Monitoring: Watch your pet's water intake, urination, and appetite closely to help determine if the treatment is working.
