Who it is for, and who it is not for

The exclusions below are the label's own. The rest is arithmetic from the panel.

The label's exclusions

Under 18

Not for use by individuals under the age of 18. The label's wording, without qualification.

Pregnant or nursing

…or by pregnant or nursing women. Also the label's wording.

A known medical condition

Individuals with a known medical condition should consult a physician before using this or any dietary supplement.

What the bottle says it is for

This matters more on this product than on most, because the bottle and the page that sells it describe two different things.

What the product is for
On the bottle
ADVANCED BLOOD SUGAR SUPPORT, printed under the name on the bottle
In the written pack
The sales page's checkout template says cognitive function and mental clarity, and the same page's keywords also list diabetes
These are not the same product category. The bottle is the document that governs, and it says blood sugar. A keyword naming a disease is a different thing again: FDA's rule is that a product intended to treat or prevent a disease is a drug, whatever the label calls it. The written pack supplied with this product flagged the clash itself — confirm the bottle, do not mix formulas — and this site follows the bottle.
Whether there is a phone number
On the bottle
+1 (877) 257 0710, under DISTRIBUTED BY
In the written pack
no public phone on the sales/contact pages we checked
The written pack could not find a phone number. The bottle prints one. It is published on this site, on this page and on the contact page, because a buyer holding the bottle already has it and a buyer who has not bought yet cannot find it.
Where the distributor is
On the bottle
Hawaiian Harmony, PO Box 12730, Ogden, UT 84404
In the written pack
Office at 1500 Broadway, Floor 6, New York, NY 10036; returns to 300 Park Avenue, Floor 17, New York, NY 10022
A post-office box in Utah against two Manhattan office addresses. A PO box is a valid address for a distributor line and it is not a street a parcel can be handed to. Nothing supplied explains how the three relate.
What it is called
On the bottle
Hawaiian Harmony, with support at northsupplements.online
In the written pack
hawaiianzharmony.com, [email protected], gethawaiianharmony.com
Four names for one transaction. The retail domain carries a z the product does not have, the sales domain carries a get, and the support address on the bottle belongs to a fourth company entirely.

Four of them. Where the two sources disagree this site follows the bottle, because the bottle is the thing a buyer can hold and read. Nothing is reconciled by guessing.

Four questions

Four questions worth answering firstevery answer comes from the label or a cited source

1. Are you buying this for blood sugar?
Yes — Then buy it from the bottle, not from the page. The bottle says Advanced Blood Sugar Support; the sales page's checkout text describes cognitive function and mental clarity. The one ingredient with a declared amount is 7 mcg of chromium, and NIH's conclusion across that whole literature is that there is insufficient rationale to recommend chromium for type 2 diabetes.
No — Then read the descriptor on the bottle before anything else, because it is a blood-sugar product and the page that sells it is not describing one.
2. Are you taking any prescription medicine?
Yes — The label says a known medical condition means asking a physician first. There is a second reason here: twenty-one botanicals and amino acids are named and not one of them is quantified, so nobody — including a pharmacist — can check an interaction against an amount.
No — The label's caution still applies if a medical condition applies.
3. Is there a dog in the house?
Yes — Then keep this bottle out of reach and off the counter. Xylitol is in the Other Ingredients list. FDA's guidance is that xylitol in dogs can cause a rapid release of insulin and a profound drop in blood sugar within 10 to 60 minutes. The amount in this bottle is not declared, which is exactly why it should not be left where a dog can reach it.
No — Then the xylitol in the Other Ingredients list is not a concern for you — it is a sweetener.
4. Can you wait six months before deciding?
Yes — Then the sales page's own advice — 180 to 210 days — is workable, and the six-bottle pack is exactly 180 days. Note that the refund window shuts on the same day.
No — Then look carefully at the arithmetic above. The sales page says to judge it at 180 to 210 days. The two-bottle pack is 60 days and the three-bottle pack is 90.

Chromium — Fact Sheet for Health ProfessionalsNIH Office of Dietary SupplementsDaily Value 35 mcg; Adequate Intake 35 mcg for men and 25 mcg for women aged 19–50; chromium-only supplements typically provide 200–500 mcg; diabetes trials used 1.28 to 1,000 mcg daily, most often as picolinate; about 1.2% of chromium is absorbed from chromium picolinate; no Tolerable Upper Intake Level was established; there is “insufficient rationale to recommend chromium supplements for people with type 2 diabetes.”
Paws Off Xylitol; It's Dangerous for DogsU.S. Food and Drug AdministrationXylitol appears in many products including dietary supplements; in dogs it “may result in a potent release of insulin” and “a rapid and profound decrease in the level of blood sugar” within 10 to 60 minutes. FDA advises checking labels and keeping such products out of reach.
