Frequently Asked Questions

Questions? We've given the answers to some of the most common ones here, and we’ll answer any questions you have if you call or email us. If we don't know the answer right away, we’ll take the time to find it! Contact us.

How long do your products stay fresh?

Our products are freeze-dried or dehydrated and are generally considered fresh within six months of their creation.  You will find a best-by date on each package, before which the product is at its best. To maximize freshness, keep BioStar products stored in a cool, dry place away from direct sunlight, and keep bags and jars closed when not in use.

If the expiration date has passed, do I need to throw away the product?

That's up to you.  Our products have a "best by" date, which means that while the product may no longer be as potent as it once was, it will not hurt to continue to use it. Similar to kitchen spices, the effectiveness may wane over time, but the supplement is not considered dangerous to use.

Is the quality of ingredients monitored?
We would have it no other way. BioStar has exceptionally high standards for every ingredient and method of production, and we use only the best, most nutritious, whole, organic ingredients for our supplement formulas. You can read all about it here.

Can humans use these supplements?

While all ingredients are chosen for exceptional quality, they are blended in specific amounts and proportions for formulas that we’ve designed for equine and canine body systems. Due to state and federal regulations, we cannot recommend our products for human use.

What if my dog or horse won't eat it?

We guarantee palatability for your horse or dog. If your animal does not like the taste, simply return the unused portion for a full refund. See our refund policy for more information.

How do I choose between similar-sounding supplements?

This is a complex question, as it depends on the supplement and the needs of your animals. See our blog post about choosing supplements, with the option of printing a PDF for future reference. Our YouTube channel provides video explanations as well. Call us if you have more questions!

Can I find these products in stores?

Our products are available in a few select stores across the US and Canada, as well as from select veterinarians and barns. See our map of stores for their locations and contact information. We do prefer to develop direct relationships with our customers, so please let us know if you're happy with the store where you’ve purchased BioStar products.

How is BioStar's bovine colostrum collected?

Our colostrum comes from cows that are grass-fed, pasture-raised, and not treated with recombinant bovine growth hormone (rBGH). The colostrum is collected only after the first 12 hours of birth and within a 36-hour time frame, when the colostrum is at its peak. Calves alone receive it during the first 12 hours; after that, it is shared. Because of the pasteurization process and a subsequent  centrifugation step, the essential IgG antibodies can be concentrated from a minimal volume of collected colostrum. Calves are not separated from their mothers, ensuring the higher quality and quantity of milk that results when a cow is allowed to raise her calf. Find more information on our colostrum here.

Are BioStar bags recyclable?

While not biodegradable (we need them to stand up to light and heat to be suitable for the supplements), our bags are recyclable as #7 plastics. If recycling is not available in your region, rest assured that our bags are considered "landfill friendly" because they collapse flat and do not impact landfills in any significant way.

What payment methods does BioStar accept?

BioStar accepts all major credit cards, as well as PayPal and Apple Pay.

How does shipping work?

Our shipping is calculated directly through USPS and FedEx, based on weight. You may notice that sometimes your actual cost is less than our website originally quoted you, and that's because we've passed on our savings. When we get a discount, you do too! For more on shipping and a map with delivery estimates by region, see our Shipping and Delivery page.

How can I manage my account and auto-shipments?

You can choose to order products once, or set up auto shipments. To manage your orders and auto-shipments, you will need an account.

If you don't have an account, you can make one by finding "Log In" at the top of any page. Once you're logged in, you'll see "My Account" at the top, and there, you can make adjustments to your account and any recurring orders.
It's easy to manage your auto-shipment delivery timing, products, and credit card information through your account.
