01 / The Problem

“High-potency” is a warning label. Not a plus.

Dr. Caldon Haj, MD, a board-certified internist and obesity specialist, has treated thousands of patients since GLP-1s arrived in 2022. He kept seeing patients get toxic doses of basic nutrients, and pay premium prices for full-spectrum multivitamins they didn’t need.

B6

Vitamin B6

Megadoses of 1,000-4,000% DV, common in B-complex products, are documented to cause peripheral neuropathy.

A

Vitamin A

Preformed retinol accumulates in the liver and is linked to toxicity and birth defects.

D

Vitamin D

Chronic over-supplementation at 300-500%+ DV drives hypercalcemia over time.

Zn / Fe / Mn

Zinc, Iron, Manganese

Accumulation risks of their own, and no “safer form” exists to fall back on.

02 / How It Works

Two buckets. Two different safety rules.

Vitamins, full strength

+100%

of the Daily Value, every day. Every B in its safest form, plus K1, K2, pre-vitamin A and full-spectrum vitamin E.

Only forms safe to repeat up to 3 times a day.

Minerals, hard-capped

25%

of the Daily Value per tablet. Every mineral, hard-capped.

Three tablets in, you’re still only at 75% of the Daily Value. Headroom left for food.

03 / Dosing

Your progress with GLP-1 changes over time. So does the dose.

1 tablet

Starting on GLP-1, you’re still hungry and don’t need much nutrient support yet.

2 tablets

An average day. Busy hours, some stress, appetite a little off. You may need to use more.

3 tablets MAX

A heavy day. High stress, illness, intense training, or a high GLP-1 dose.

04 / Formula

Nothing hidden. Nothing hyped. Complete, safe support for GLP-1 patients.
