What’s in a Name? Understanding the Different Forms of Nutrients in Your Supplements

Introduction

Ever flipped over a supplement label and seen words like magnesium glycinate, iron bisglycinate, or P5P — and wondered why the name sounds more like a lab report than a vitamin?

It's not just marketing fluff.

The form a nutrient comes in can affect:

• How well it absorbs
• How your body uses it
• Whether it's even effective at all

At Patched Up, we carefully select nutrient forms based on what the body needs — not what's cheapest, trendiest, or easiest to label. This guide will explain the forms we use in our patches, why they matter, and what to watch for when choosing supplements.

🔹 1. Magnesium — It's Not All the Same

Magnesium exists in many forms, each serving different functions in the body.

Magnesium Chloride

🩹 Used in our Magnesium Patches

• Highly absorbable through the skin
• Supports muscle relaxation, nerve function, and hydration
• Great for topical use — no gut involvement required

Magnesium L-Threonate

🌙 Used in our Sleep Patches

• Known for its ability to cross the blood-brain barrier
• Supports memory, learning, and deep sleep
• A highly targeted magnesium for brain and nervous system support

🔹 2. Iron Bisglycinate — A Smarter, More Absorbable Form

Iron Bisglycinate

🩹 Used in our Iron Patches

• Iron bound to the amino acid glycine
• Improves absorption and helps reduce common side effects like nausea and digestive upset
• Especially useful when delivered through the skin, bypassing the gut entirely

🧭 Why do Different Forms Exist - and Why You Should Care

Supplement companies don't always pick the most bioavailable form. They pick:

• What's cheap
• What's easy to market
• What fills a label (even if it barely absorbs)

The result? Many people take supplements they don't fully absorb — or can't use efficiently due to gut issues, methylation problems, or poor formulations.

At Patched Up, we source patches with:

• Activated forms (like methylcobalamin)
• Chelated minerals (like Iron Bisglycinate)
• Skin-ready compounds (like Magnesium Chloride)

⚠️ A Quick Myth to Bust

If you ever hear a company describe a supplement as "gentle through the skin", take a pause.

That's a term used for gut-based products, where ingredients might irritate the stomach. But when it comes to transdermal delivery, "gentle" doesn't apply.

Nutrients either pass through the skin barrier, or they don't. It's about absorption, not comfort.

When brands misuse terms like that, it often means they don't fully understand the science — or they're relying on generic AI-written marketing.

Unlike Patched Up, which is science-backed and built by someone who understands the biology — and knows how to talk about it properly.

✅ Final Thoughts

The name on your supplement label matters.

It tells you whether the nutrient is ready to be absorbed, or whether it's just filler in disguise.

If you're currently taking a supplement with a second name you don't understand, let me know in the comments and I'll research it for you.
