Form Invalidation: Why “L-Theanine” Isn’t Always L-Theanine

Just Because It Says “Suntheanine®” Doesn’t Mean It Is Suntheanine®

You’ll see labels like: “With Suntheanine®!” But check the fine print — sometimes, it’s not even in the formula. Or worse — they use a cheap, unproven version and hope you won’t notice. This is called form invalidation.

🔍 What Is Form Invalidation?

Using a generic or inferior form of an ingredient instead of the one proven in science. Think of it like buying “diamond” jewelry… only to find out it’s cubic zirconia. Same name. Different quality.

🧪 How Companies Do It

• Use generic L-Theanine instead of Suntheanine® (the only form studied in humans)
• Use magnesium oxide instead of magnesium L-threonate (Magtein®) — even though only Magtein® crosses into the brain
• Use mycelium-based Lion’s Mane grown on grain (mostly starch) instead of fruiting body with 30% erinacines

They save money — you get less results.

🚪 How They Get Away With It

• The generic name is the same (“L-Theanine,” “Magnesium,” “Lion’s Mane”)
• No requirement to specify the form
• Most consumers don’t know the difference

🔴 Red Flag to Watch For

❗ If a product says “L-Theanine” but doesn’t say Suntheanine®, it’s probably not the real thing.

Same goes for:

• “PQQ” → look for BioPQQ®
• “Magnesium” → look for Magtein®
• “Lion’s Mane” → look for fruiting body + % erinacines

If it’s not specified, it’s likely inferior.

⚖️ Real Example: Class Action vs. Nootrobox (now HVMN) – 2017

A lawsuit was filed against Nootrobox (maker of “Rise”) for claiming their product contained Suntheanine® — but independent testing found no detectable levels of it. The suit alleged false advertising and misleading labeling.

✅ Outcome: Settled with changes to labeling and marketing practices.
