Best Senior Horse Supplement Reviews

Many supplements can really put a spring back into your older horse’s step, so if you are wondering what are the best senior horse supplements then read on – we have selected three of the best supplements for you to select the one that is most suitable for your senior horse’s needs. These are:

  1. Manna Pro 1030167 Senior Equine Supplement
  2. Acti Flex Senior Powder
  3. Purina Mills Equine Senior Active

1. Manna Pro 1030167 Senior Equine Supplement Review

Manna Pro 1030167 Senior Equine Supplement, 30 lb Bag

This is a fantastic, non GMO supplement that is carefully designed with the needs of the older horse in mind. It can produce astonishing results in a very short space of time, bringing new life to your old horse.


  • Easy to digest – The extruded pellets are easier for the body to process, meaning that more of the good stuff will be getting to where it needs to go for best results faster.
  • Added joint support – For those old, stiff bones that need a little more than they used to, this supplement contains Glucosamine and Chondroitin Sulfate.
  • Contains Vitamin C and Omega 3 – Vitamin C is one of the body’s most important defence mechanisms. It can help fight off infection and keep the cogs running smoothly, while Omega 3s are widely credited with great all round health.
  • 30 day supply – You won’t have to worry too much about your bank balance, as this supplement will keep you going for at least a month.


  • Small packaging – About the only downside to this product is that 30lbs may not be sufficient for every horse owner. Personally I would like to see a slightly larger sizing.


If you are looking for a great supplement that can make your friend feel 10 years younger, put weight on where it’s needed and improve the topline as well as the coat, this is the supplement for you.


2. Acti Flex Senior Powder Review

Acti Flex Senior Powder 16 lb

A nutritional supplement to help with flexibility and maintaining a good weight, this one contains probiotics that can greatly help the reduced digestive function in older horses. It’s tasty and palatable too, meaning that even those with a reduced appetite should get stuck in.


  • Comes in an alfalfa powder base – This is extremely palatable to most horses, and means that you can be sure that they will eat it and therefore take on board all the nutritional benefits.
  • Can reduce the need for painkillers – Using this supplement can support the joints in a way that means they won’t be as painful or inflamed as they were before, so you won’t have to dose your horse up on Bute for the rest of time.
  • Improves the coat – As an all round indicator of general health, having a good coat is paramount. This supplement will make them shine, so you can see it is doing them good from the inside out.
  • Comes in a huge supply – Offering a 256 day supply, this supplement is an investment for your old friend. Spending a bit more money on it won’t seem so painful when you realise it will last for nearly a year!


  • High price – The price for the 16lbs product is on a high side compared to some other supplements on the market (at the time of this review).


Acti Flex Senior Powder is a smart choice if you are looking for a good supply of a decent supplement that will last, and will offer good protection for your horse’s coat and hooves.


3. Purina Mills Equine Senior Active Review

Purina Mills Equine Senior Active 50 lb. Bag

This supplement is great for weight gain, hoof condition and coat. It is designed with the older horse in mind, to give them a bit more oomf! Made from flax seed, rice bran and vegetable oil as well as the added extras, this supplement can do nothing but good.


  • Contains prebiotics – Did you knw there was a prebiotic as well as a probiotic? The prebiotic is great for supporting the autoimmune system as well as overall health.
  • High fat and fibre formula – This can help control blood sugar levels, as the starch and sugar content is controlled.
  • Contains vitamin E – One of the go-to vitamins for skin, the vitamin E in this supplement will help your best friend’s skin and coat no end.
  • Good for maintaining a healthy weight – Older horses tend to drop weight very quickly due to the reduced gut performance. This supplement can help them keep it on, meaning that they are more robust and better able to withstand infections, health issues and winters.


  • Cannot be shipped out of the US – If you live elsewhere in the world, you will have to find another supplier of this product.


A great supplement for maintaining weight, and hoof condition, in the older horse. This is a relatively inexpensive product that can boost your horse for years to come! There is no price to great to pay for the knowledge of having your horse being as well as he possibly can be.



If you are looking for something to put a spring in the step of your older horse, the look no further than a good supplement to their feed to help them feel their best.

If you want a great supplement that contains no GMO ingredients and that can support your older friend, go for Manna Pro 1030167 Senior Equine Supplement. If you are looking for a good supply of a decent supplement that will last ages, and will offer good gut protection as well as improving the coat and hooves, opt for Acti Flex Senior Powder. If your older four legged friend is looking for an immune-supporting supplement that will also help good weight gain, choose Purina Mills Equine Senior Active.
