Spermidine Supplement

$19.98 ~~$119.85~~ In stock

Spermidine is a polyamine molecule essential to cellular metabolism, present in foods like wheat germ, soybeans, aged cheese, and mushrooms — but only in trace amounts. To reach the doses studied in human aging research (typically 1.2–6mg per day), most people need a supplement.

Double Wood's Spermidine is a single-compound formula: 99% pure spermidine trihydrochloride (3HCL), the water-soluble salt form used in clinical research. Each two-capsule serving delivers 10mg of verified spermidine — independently tested by HPLC every batch, with full results published on this page. No wheat germ extract, no fillers, no batch-to-batch potency drift.

Soy-Free, Gluten-Free, Non-GMO, Vegan

Three weeks in and I’ve noticed my afternoon brain fog doesn’t hit the same way anymore. The 1mg capsules are a breeze to take with breakfast, and getting a dose that’s actually comparable to what’s studied feels like a real upgrade from munching on wheat germ.

The capsules are easy to swallow and don’t leave any aftertaste, which matters to me since I’m picky about supplements. I’ve noticed my afternoon brain fog feels lighter, and knowing it’s sourced from things like wheat germ and soy makes it feel less synthetic.

The capsules are easy to swallow and don't leave any aftertaste, which I appreciate. I've been taking them for about three weeks now and feel a bit more focused in the afternoons, though it's hard to say if it's the supplement or just better sleep.
