What this record means
The record shows that “VAZOOM VITAMINS + ANTIOXIDANTS ON ICE” is cancelled; the registration was on the Principal Register (Reg. 3691752) but was cancelled on May 13 2016 because the owner, American Instants, Inc., did not file an acceptable Section 8 declaration, and the record lists no later activity. The only goods covered are “non‑alcoholic beverages, namely, vitamin‑enriched water, vitamin‑fortified beverages” in International Class 005, so a similar name used for drinks or other health‑related beverages would be the closest record‑based concern, while uses in unrelated categories would be farther from the scope shown. The record does not give the owner control over every possible use of the words “Vazoom,” “vitamins,” or “antioxidants.” No Supplemental Register filing appears, and the prosecution history simply reflects the standard examination steps leading to registration and later cancellation. The supplied history shows no oppositions, cancellations by third parties, or court actions, so there are no visible enforcement signals. I'd treat this as a moderate concern if you plan a comparable name for beverage products, because the cancelled registration still signals that the USPTO once linked the wording to that specific type of product.
