Our verdict: A micronutrient top-up with a declared live yeast and FOS, rather than a dedicated probiotic. Clear feeding rates and stated NOPS audit status are strengths; the cereal-based carrier and the risk of doubling up with a feed balancer are the main points to weigh.
May suit
- Forage-fed horses needing a small vitamin and mineral top-up
- Owners wanting micronutrients and a live yeast in one scoop
- Short spells of extra support at the concentrated rate
What we like
- Full declared vitamin, trace element and amino acid profile
- Named live yeast strain with a declared count
- NAF states BETA NOPS audit for FEI competition
- Clear rates for horses and ponies
Things to consider
- Contains wheat feed and cooked maize
- Risk of doubling up on trace elements alongside a balancer
- FOS amount per serving not stated

NAF In The Pink Powder, often just called Pink Powder, is a long-standing name in UK yards. NAF files it under balancers and describes it as providing vitamins, minerals and micronutrients to support overall condition, with added gut support to help nutrient uptake. This is a desk review based on NAF's published product information, checked on 11 November 2026, and on research into the main ingredient types. We have not fed or tested it.
What it is
Pink Powder sits between two categories. It contains a live yeast and fructo-oligosaccharides, so it overlaps with gut balancers, but most of the declared additive list is made up of vitamins, trace elements and amino acids. NAF's own framing is condition and overall health first, gut support second. It is sold in 700g, 1.4kg and 2.8kg pots, which NAF lists as roughly 30, 60 and 117 days' supply respectively.
That dual role is the key to judging it. If you want a pure probiotic, this is not that. If you want a small daily top-up of micronutrients with a live yeast included, it is designed for exactly that job.
Declared key ingredients
The composition is listed as wheat feed, brewers' yeast (inactivated), cooked maize, calcium carbonate, monocalcium phosphate, maltodextrin, refined rapeseed oil, beetroot juice, dried carrot, sodium chloride, fructo-oligosaccharides and magnesium oxide.
Live yeast
The digestibility enhancer is Saccharomyces cerevisiae CNCM I-4407 (4b1702) at 4.05 x 10 to the power of 11 CFU per kg, or 405 billion CFU per kg. At the 24g maintenance rate for a horse, that is roughly 9.7 billion CFU a day by our calculation. This is the same strain declared in Protexin Gut Balancer, and the daily count at maintenance rates is similar.
Vitamins, trace elements and amino acids
Per kg, NAF declares vitamin A at 222,000 IU, vitamin D3 at 36,900 IU, vitamin E at 16,400 IU, biotin at 23.6mg and a full set of B vitamins including B1, B2, B6 and B12, along with folic acid, niacinamide, pantothenate and choline. Trace elements per kg include copper at 3,700mg, zinc at 2,960mg, manganese at 1,480mg, iodine at 14.7mg and selenium at 5.91mg from selenised yeast. The amino acids lysine, methionine and glutamine are also added.
What that means per day
Supplements list additives per kg, so it helps to scale them to the daily dose. At 24g a day, our arithmetic gives roughly 89mg copper, 71mg zinc, 0.14mg selenium, 394 IU vitamin E and 0.57mg biotin. For comparison, the well-known hoof studies used 20mg of biotin a day (Josseck and colleagues, 1995), so Pink Powder is not a hoof supplement. Whether these trace element levels are enough for your horse depends on the forage and other feeds, which is why a ration check is useful. Our guide to vitamins and minerals explains how to think about this.
What the research says
There is no published trial of Pink Powder cited on the product page, so we have looked at the ingredient types. Live yeast has shown improved fibre digestibility in some horse studies, including work on high-starch diets (Jouany and colleagues, 2008), but other trials in healthy horses found no measurable change, and a review concluded that the evidence behind commercial equine probiotics remains limited (Schoster and colleagues, 2014). The vitamins and minerals are well-understood essential nutrients, and their value depends on whether the rest of the diet already supplies enough.
How it is fed
NAF supplies a 10ml scoop that holds about 8g. For horses over 400kg, the rate is 32g (four scoops) a day for concentrated use and 24g (three scoops) for maintenance. For ponies up to 400kg, it is 24g (three scoops) concentrated and 16g (two scoops) maintenance. NAF suggests feeding the concentrated rate at peak requirements such as poor condition, regular travel or a move to a new yard, and says not to exceed the recommended rates.
That instruction not to exceed the rates matters because of the trace elements, especially selenium, which should not be stacked from several sources without checking the total.
Who it may suit
Pink Powder may suit a horse on a mostly forage diet with little or no hard feed, where the owner wants a small top-up of vitamins and minerals plus a live yeast in one scoop. It may also suit owners wanting extra support during travel or a yard move, using the concentrated rate for a spell. Competition riders will note that NAF states it is audited under the BETA NOPS scheme as suitable for FEI competition.
Limitations
- It contains wheat feed and cooked maize, so it is not cereal free.
- Adding it to a diet that already includes a feed balancer could double up on trace elements and vitamins.
- The amount of FOS per serving is not stated.
- No product-specific trial is cited on the product page.
- The biotin level is far below the doses used in hoof research.
Things to check before choosing it
BETA NOPS and competition rules
NAF states that In The Pink Powder is audited under the BETA NOPS scheme as suitable for FEI competition, and tells owners to check with the relevant authorities if racing or competing internationally. Follow that advice and check your own governing body's rules.
Cereals and sugar
Wheat feed and cooked maize appear near the top of the composition, and maltodextrin and beetroot juice are also listed. At 16g to 32g a day the total quantities are small, but owners managing laminitis or another condition where starch and sugar are restricted should ask NAF for the analysis and discuss it with their vet. See our guide to choosing a supplement for questions to ask.
Cost per day
NAF's own figure is that a 700g pot lasts about 30 days at 24g a day. Divide the pot price by its weight in grams and multiply by your daily rate. Remember that this one product covers both micronutrients and gut support, so compare it against the cost of a separate gut balancer plus a vitamin and mineral supplement, not against a probiotic alone.
Our verdict
NAF In The Pink Powder is best understood as a micronutrient top-up with a live yeast included, rather than a dedicated probiotic. It declares a full vitamin and trace element profile, a named yeast strain and clear feeding rates, and NAF states NOPS audit status. The cereal-based carrier and the risk of doubling up with a balancer are the main points to weigh. For a forage-fed horse that needs a small all-round top-up, it is a sensible candidate.
