Frequently Asked Questions

What is new with OPC Synergy®?

Due to sourcing issues, Standard Process has secured a new supplier for the grape extract in OPC Synergy®. This new source comes from the wine-making process in France and contains added sulfites.

Where do sulfites come from?

Small amounts of sulfites are naturally occurring in some foods including apples, rice, onions, and cabbage.1 They are also used as a food additive to increase shelf-life or to halt fermentation.

Why are sulfites listed on the label of OPC Synergy®?

Some individuals can be sensitive to sulfites, resulting in reactions such as hives, asthma, or anaphylaxis. Products containing added sulfites must be labeled as such if sulfites exceed 10 parts per million.2

If someone is allergic to sulpha drugs, will they have a reaction to sulfites?

Not necessarily, these are two separate allergies with no direct connection to each other. Sulfites are different than sulpha drugs, antibiotics, and other medication that contain a sulfonamide molecule.

KONG Tug Toy
This tug toy is decent but not amazing. It’s sturdy enough for light play, but it doesn’t hold up as well as other KONG toys we’ve used. My dog enjoyed it, but the material started to wear faster than expected, and it didn’t feel as durable as the usual KONG quality. It’s fine for occasional tug sessions, but not the best choice for strong pullers or heavy chewers.

Best toy for a puppy who loves tug-o-war
My puppy (lab/shepherd) went nuts for this toy. She loves to play tug-o-war. This is so durable and the grip handles on the end totally help you out. She loves to bit in the middle and will whip it at you to get you to engage with her. The size is perfect for her and the KONG material must feel good for her.

Kong didn't survive this guy.
He had it for an hour.. We played tug for around 10 minutes then he took it off and chewed it up.. I thought Kongs were tougher to chew up.. very dissapointed.

One of the best dog toys we've found
This is one of my little girl's favorite toys. She's an aggressive chewer so at first we followed the manufacturers instructions not to let her use as a chew toy. It was purchased in January 2025, but it's holding up just fine. She likes to turn it into a pretzel for some reason, but hey it keeps her entertained! Highly recommend.
