BioStar's Line of Optimum Wellness Formulas

Which Optimum wellness formula is best for my horse or dog?

BioStar offers a range of wellness formulas with vitamins and minerals, called Optimum. With so many choices, we’ve put together this guide to help you choose the right Optimum formula for your horse or dog.

A brief history of Optimum

When the first Optimum wellness formula was designed in 2008, it was unlike any other multivitamin and mineral for horses on the market. The original Optimum is a bar, like a cookie, that can be fed by hand or added to feed. Unlike other equine multivitamin supplements, Optimum was designed to focus on bioavailability by providing horses with nutrients from real whole foods. To best maintain their raw whole food state for maximum absorption, the bars are dehydrated rather than cooked.

We learned several things about the Optimum bars: some horses preferred a powdered form, so we began grinding our Optimum bars into powder. Commercial mill grinders are nothing like a food processor or even a Vitamix blender – the process is more like having a hungry, noisy velociraptor in the production area. Luckily no human fingers have been lost in the grinding process. Thus, Optimum powder was born. Using the ground bars as a base, we began expanding the line by adding specific ingredients for additional support to make Optimum Senior, Optimum with Joint Support, and Optimum Senior with Joint Support. As we sought to further provide support for horses with a multitude of individual needs, we released Optimum HW for metabolic horses and Optimum GI for ulcer support.

Another early observation was that dogs hanging around the barn were stealing Optimum bars out of the feed buckets, as were some crafty raccoons raiding feed rooms. Thus, Optimum K9 was born, taking a cue from so many of you who told us about your dogs’ love of the horses’ Optimum bars. Of course, we had to tweak it a little, including the inclusion of desiccated beef liver for protein and B-complex vitamins, including B12.

The Evolution of Optimum 2.0

Doing nutrition consultations for horse owners revealed that more precise mineral support was needed. Upon reviewing countless hay analyses, some hays were substantially low in magnesium, copper, zinc, selenium, and manganese. I was very concerned by the iron content in some of the hays I was reviewing.

Through a friend who is an expert in the human supplement industry, I learned of a mineral company in Utah, which specializes in “caging” mineral molecules with amino acids from rice. This means the mineral molecule is encased in protein for high bioavailability. This encasement is very similar to what plants do when they uptake minerals from soil: they chelate (bind) minerals to free amino acids.

With this mineral company on hand, BioStar now had the opportunity to customize a full-range of proteinated mineral complexes. Most equine supplement companies only use proteinates for one or two minerals (copper or zinc, for example). It’s very expensive to use proteinates for macro and micro minerals, yet proteinates are the most bioavailable for the body. Proteinates mimic the plant-chelated minerals the horses take in when they eat grass or hay, unlike carbonates and oxide forms of minerals, which are just ground up rocks. Even plants can’t use rocks without first chelating them with amino acids.

Armed with this research, wellness formula Optimum 2.0 was born, representing a new standard in full-spectrum bioavailable minerals for horses.

BioStar’s entire Optimum line does not contain added iron because too much iron can lead to oxidative stress. The iron in our Optimum supplements is naturally occurring in the ingredients we use.
