Selenium toxicity is real. Copper antagonism with iron and molybdenum is real. The Zinc-to-Copper ratio matters more than either number alone. A mineral test answers all three in one report — 16 essential minerals, 7 critical mineral ratios, and 8 toxic metals competing for the same absorption sites. From a 1.5-inch mane sample. $49.99.
A horse hair mineral test is only as useful as the minerals it actually measures. Cheap panels stop at the easy ten. The Mane Metrics panel reports the full set — because the missing minerals and the wrong ratios are exactly where the answer usually lives.
These are the structural and metabolic inputs every horse needs. Bone, hoof horn, muscle, coat, hormones, recovery, immune function — all of it traces back to this list.
Single-element numbers can mislead. The ratios are where you see how minerals actually compete for absorption and use. A horse can be technically "adequate" on copper and zinc and still be functionally deficient if the Zn:Cu ratio is off.
The bone, joint, and growth ratio. Should sit between 1.5:1 and 2:1, with calcium always at or above phosphorus. Inverted Ca:P drives DOD in young stock and bone density loss in performance horses on grain-heavy diets.
The coat, hoof, and immune ratio. Both minerals compete for the same gut transporter. The ratio between them tells you whether either is actually being utilized — regardless of what the supplement label promises.
The functional copper deficiency ratio. High iron — from forage, water, or fortified feed — directly suppresses copper utilization. This is the single most common antagonism finding in U.S. working horses.
The hydration and stress ratio. A meaningful drift here flags chronic stress, electrolyte management problems, or adrenal load before clinical signs show up.
The neuromuscular ratio. High calcium against low magnesium correlates with the spookiness, tightness, and stress reactivity people often try to fix with behavior tools instead of nutrition.
The thyroid and metabolic-rate ratio. A useful early indicator that the metabolic engine is drifting before standard thyroid bloodwork would be ordered.
The adrenal stress ratio. Tracks how well the horse is buffering the chronic stress load of training, transport, or environment over a multi-month window.
Toxic metals do not just cause their own clinical problems — they actively compete with essential minerals at the absorption stage. You cannot out-supplement a heavy-metal load. The source has to be identified, and the panel is how you find it.
This is a mineral test that uses hair as the sample medium — not a hair test that happens to measure minerals. The reason is straightforward: blood and hair carry mineral information differently, and for the question most owners are actually asking, hair is the better instrument.
Blood is a tightly regulated compartment. The body works hard to keep serum calcium, magnesium, iron, and most other minerals inside a narrow clinical range — even if that means pulling from bone, muscle, and stored reserves to do it. A "normal" mineral panel on bloodwork does not mean the horse has normal mineral status. It means the regulatory system is succeeding at the borrowing.
Hair behaves differently. As the mane shaft forms at the follicle, it incorporates elements from circulation and locks them in place. The shaft does not re-equilibrate. A 1.5-inch mane sample is, in effect, a 60-to-90-day record of what the horse actually retained — not what it was momentarily holding the day blood was drawn.
That gives a hair-based mineral panel three structural advantages for the mineral question:
The point is not that hair beats blood. The point is they answer different questions. Blood is the right tool for acute clinical chemistry. Hair is the right tool for the mineral-status question. Use both intelligently.
$49.99 per kit. 16 minerals, 7 ratios, 8 toxic metals — one report. Call (972) 284-1878.
These are the questions that walked into the diagnostic. If any of them sound like the horse standing in your barn, this is the panel that will close the loop.
The U.S. selenium map is brutally uneven. Pacific Northwest, Great Lakes, Northeast, Atlantic coast — selenium-poor soils. The forage carries the deficit straight in. The flip side is overshooting with multiple supplements and tipping into toxicity. The panel quantifies actual selenium status so you correct precisely.
Because iron, zinc, sulfur, and molybdenum all compete with copper at the gut. A horse on iron-rich well water or iron-fortified feed can be functionally copper-deficient with a copper supplement on top. The Fe:Cu and Zn:Cu ratios are how you actually see this.
A lot. Serum iron is regulated tightly. Forage and well-water iron load gets stored, not measured. Iron overload then suppresses copper and zinc utilization, and the horse shows it as dull coat, weak hoof horn, slow recovery. The mineral test reads what the body actually retained.
1.5:1 to 2:1, calcium always at or above phosphorus. Grain-heavy diets invert this and drive bone, joint, and growth issues. The panel reports the ratio — not just the individual numbers — because that is the metric the bones actually respond to.
It is almost always the ratio. High calcium against low magnesium correlates with neuromuscular tightness, reactivity, and the kind of "won't settle" behavior people try to train through. The panel reports both numbers and the ratio so you can stop guessing.
Worth checking. Old paint, treated wood, untested well water, agricultural runoff, industrial drift — all leave fingerprints in mane months before bloodwork would catch them. The toxic-metal tier of the panel exists for exactly this question.

Email + voice debriefA mineral panel is not a plan. Most labs hand over a chart and leave the operating decisions to the owner — which is reasonable for a chemist and useless for a barn. The Mane Metrics process closes the gap with a phone call, because the actual question on the table — "okay, but what should I feed and what should I change?" — deserves a direct answer from someone who has run the panel on their own horses.
Approximately 9 to 12 calendar days from order to written mineral report. Faster than most veterinary follow-up appointments can be scheduled.

Hair-based mineral analysis in horses is supported by a published, growing literature — strongest for trace mineral tracking and heavy-metal exposure detection. The studies below are the current reference set.
The questions owners ask before ordering — selenium, copper, iron, ratios, and what bloodwork actually misses.
A horse hair mineral test is a quantitative laboratory panel that measures the actual mineral status of a horse — essential minerals like selenium, copper, zinc, calcium, magnesium, and iron, the ratios between them, and the toxic metals competing for absorption. The Mane Metrics panel uses ICP-MS on a 1.5-inch mane sample, because hair stores roughly 60 to 90 days of mineral and exposure history. That is the time window where deficiencies and overloads actually live.
Order the $49.99 kit. Snip ~1.5 inches of mane near the crest with clean scissors, seal it in the bag with the intake card, and drop it in the mailbox. The lab runs ICP-MS across 16 essential minerals, 7 critical ratios, and 8 toxic metals. You receive a color-coded mineral report in roughly 9 to 12 days, plus a phone debrief that turns the numbers into a feed and supplementation plan.
Selenium status is one of the most useful single answers the mineral test returns. Large parts of the U.S. — the Pacific Northwest, the Great Lakes region, the Northeast, much of the Atlantic coast — sit on selenium-poor soils. The forage carries that deficit straight in. The other half of the problem is selenium toxicity, which is real in horses double-supplemented across multiple feeds. The mineral panel quantifies actual selenium status so you correct the gap without overshooting in the other direction.
Copper is the textbook example of why the number on a feed tag does not equal absorbed mineral. Iron, zinc, sulfur, and molybdenum all compete with copper at the gut. A horse on high-iron well water or iron-loaded forage can be functionally copper-deficient even with a copper-fortified supplement on top. The mineral panel measures the Zinc-to-Copper and Iron-to-Copper ratios — that is where you actually see whether copper in the bag is reaching the horse.
Yes — and it is one of the most common findings in U.S. working horses. Most forage, most pasture soil, and a lot of well water are iron-rich. Layered with iron-fortified commercial feeds, the horse ends up oversupplied. Iron overload then suppresses copper and zinc utilization, which shows up as a dull coat, weak hoof horn, slow recovery, and topline issues. Routine bloodwork rarely flags this because serum iron is tightly regulated. The mineral panel catches it because hair records what the body actually retained over the prior season.
For a mature horse, Ca:P should sit between 1.5:1 and 2:1, with calcium always at or above phosphorus. For growing horses, broodmares, and racehorses on grain-heavy diets, this ratio is even more sensitive — inverted Ca:P drives DOD, joint, and growth issues. The mineral test reports the Ca:P ratio explicitly because the individual numbers do not tell you whether the bones are getting what they need.
Blood is a regulated compartment. The body works hard to keep serum levels of calcium, magnesium, iron, and most minerals inside a tight clinical range — even while pulling from bone, muscle, and stores to do it. Normal bloodwork does not mean normal mineral status. It means the body is succeeding at the regulation. A hair-based mineral test reads what was deposited into a slow-growing tissue over the prior season — a more honest record of what the horse actually has versus what it is borrowing.
Zinc and copper share the same gut transporter. They compete for absorption at the cell wall. A horse can be technically "adequate" on both minerals individually and still be functionally deficient if the ratio is off — typically too much zinc against too little copper, or vice versa. The Zn:Cu ratio is one of the highest-yield numbers on the entire mineral report. It tells you whether the supplementation is actually working, not just whether the minerals are present.
A generic supplement program is a guess based on a category — "performance horse," "broodmare," "senior." A mineral test is data on this horse, on this farm, on this forage, on this water. A horse already iron-loaded does not need an iron-containing performance pack. A horse with a low Zn:Cu ratio does not need a copper-only top-dress. The test stops you spending against the marketing label and starts you spending against what is actually missing.
No. The mineral test is a wellness, nutrition, and exposure assessment tool. It is designed to inform feeding, supplementation, and environmental decisions. The report uses language such as "suggests," "indicates," or "may correlate with." Diagnosis and treatment of disease remain the responsibility of your attending veterinarian, who should always be the lead on clinical decisions.
The mineral test kit is $49.99. That covers the collection kit, the return mailer, ICP-MS analysis of all 31 reported readouts (16 essential minerals + 7 ratios + 8 toxic metals), the color-coded mineral report, and the follow-up phone debrief. Total elapsed time from order to written report is roughly 9 to 12 calendar days.
