Worth more than the barn.
When Amos’s barn burned, the insurance investigator valued what was inside at $47,000, more than the barn itself: two hundred pounds of carefully prepared magnesium stores, the same forms his grandfather learned in 1947.
Dr. Brennan had tried the drugstore bottle first. He turned it over: magnesium oxide, about 4% absorbed in one study. Then he found the four forms in one bottle and drove it back to Lancaster.
What we won’t tell you: that a supplement replaces a prescription, or changes your blood pressure or cholesterol. If your doctor prescribed something, keep taking it, and take this label to your next visit.
What we will show you: the label Amos read, held up to 4 plain rules, so you can check the bottle in your own cabinet.
- Forms named
- No oxide
- All four jobs
- Doses printed
You read Dr. Brennan’s letter. Here is the label Amos turned over in his hand, held up to every rule, so you can check it against the bottle in your own cabinet.
Most magnesium on the shelf won’t do the job, and the back of the bottle tells you which ones will. Here are the checks from the letters, held up to the real Supplement Facts panel. It takes about 30 seconds.
The forms are named
Pass
No proprietary blend, and no “magnesium complex” with the amounts hidden. Every form is listed by name: magnesium L-threonate, magnesium bisglycinate chelate, magnesium malate and magnesium taurate. Plus vitamin B6 as P-5-P, the active form.
Gold Seal Magnesium Complete: the bottle from the letter

120 capsules · 4 a day · 30-day supply
It isn’t sold on Amazon or in stores. The links on this page go to Gold Seal’s own site, so you know you are getting the real one.
No oxide anywhere
PassOxide is the cheap form. In an absorption study only about 4% of it was absorbed.1 It is also the form that hides on the back of bottles that say glycinate on the front. This label has none.
All four jobs are covered
PassOne form fills one job. The letters asked for all four, and this label covers each one with its own form.
The doses are printed plainly
Pass
Trial amount2,000 mg of magnesium L-threonate, the same amount used in the 2026 clinical trial.3 Then 550 mg bisglycinate chelate, 300 mg malate, 100 mg taurate and 10 mg of B6. Together that is 298 mg of elemental magnesium in a 4-capsule serving.
2,000 mg is the weight of the whole magnesium L-threonate compound. Magnesium is only part of each molecule, so it gives 144 mg of actual (elemental) magnesium. Add the other three forms and you get 298 mg of elemental magnesium, the number on the Supplement Facts panel (71% of the Daily Value).
| On the label | Elemental |
|---|---|
| Magnesium L-threonate, 2,000 mg | 144 mg |
| Bisglycinate, malate + taurate (550 + 300 + 100 mg) | 154 mg |
| Total per 4 capsules | 298 mg · 71% DV |

The number on the chart can look fine while the tank runs low
The red square is roughly what a blood test sees.4
Less than 1% of your body’s magnesium is in your blood.4 The rest sits in your bones and inside your cells, and that is where it runs low. So the test comes back normal while you keep feeling it at 3 a.m., in your feet and in the afternoon fog.
Some of the most common daily pills are linked to lower levels. In a study of 1,106 older adults, people taking one of the most widely used blood-sugar medicines had 3.7 times the odds of low blood magnesium.5 Never stop or change a medicine without your doctor. Ask about your magnesium instead.
What people say after they switched
“My wife and I started your product about 2 months ago and we have found that we have a better sleep pattern and typically have an 8-hour sleep. I checked with my previous company that we bought a magnesium supplement from, and they could offer no specifics or benefits to the compound they used, which was just one. I was impressed with gold seals delineation of how various magnesium compounds affect the body. We plan on using gold seal from now on.”
“I bought this and the very first evening I got a good night sleep. It continues to give me a good night sleep. I have 3 other bottles the other brands, they never made a difference. I hate you have to take 4 a day but it's worth it.”
“I'm just finishing my 1st bottle of a 6-month supply purchased. I'm beginning to notice the lack of feeling tired/exhausted all the time. I'm sleeping better without the use of sleeping aids and feeling more mentally alert. I'm a nurse and had a feeling this was the right formulation for all my needs. Thank you!”
“My magnesium lab value is in the normal value for the 1st time ever!”

Before you order
Is this the same bottle from the letter?
Yes. Gold Seal Magnesium Complete: magnesium L-threonate 2,000 mg, bisglycinate chelate 550 mg, malate 300 mg, taurate 100 mg and vitamin B6 as P-5-P 10 mg, in a bottle of 120 capsules.
How do I take it?
The serving on the label is 4 capsules a day with water, and the doses are printed for that serving. Take them at the times that suit your day.
Why not buy magnesium at the drugstore?
Most drugstore bottles are oxide, or one form with oxide on the back. Run the four checks above on any bottle you are thinking about.
Can I take it with my medication?
Magnesium can interact with some medicines. Ask your doctor or pharmacist first, and never stop or change a prescription on your own.
How soon will I notice something?
Many people say they notice their nights first, within the first few weeks. Give it the full 30 days. That is what the guarantee is for.
What is the guarantee?
30 days on every order. If it doesn't work for you, email support@goldsealsupplements.com and you get every penny back. You don't have to send anything back.
Do it the way the letter said
