Spermidine

If you're new to spermidine, here's the short version. It's a natural compound your own cells make, and it's also found in everyday foods like mushrooms, legumes, and aged cheese. Your body's levels may decline with age, which is one reason people take it as a simple daily way to support cellular health.* The harder part is choosing a bottle, because the shelf is full of options that look alike but aren't.

Most spermidine supplements come in one of two forms. Some use wheat germ extract, a food concentrate whose spermidine content can vary. Others use purified spermidine in a stable salt form called spermidine trihydrochloride, or 3HCl. Research hasn't shown one form to be better than the other, so the choice mostly comes down to consistency and convenience.

We chose purified spermidine trihydrochloride because it's consistent from batch to batch and easy to measure, and we put 15 mg of it in every capsule, listed exactly that way on our Supplement Facts panel.

That choice also made it simple to take. Among products that use the same purified form, most put 5 to 10 mg in each capsule and ask you to take two, and a day's serving often costs between $0.65 and $1.50. Ours has 15 mg in a single capsule, so one a day is all it takes, about $0.27, and one bottle lasts four months. The label also lets you move up to 2 capsules a day after the first week, and at that pace a bottle lasts two months.

And because consistency only counts if someone checks it, every batch is tested before it ships, and every bottle is made in the USA, under FDA cGMP, from globally sourced ingredients. You can open the original report on our Lab results page by matching it to the batch number on your bottle.

So if you're looking for a spermidine you don't have to second-guess, that's what we set out to make: one clearly labeled form, 15 mg in a single capsule, about $0.27 a day, tested batch by batch, and made in the USA. We hope it becomes one simple, honest part of your day.
