In a 20-year study comparing 146 compounds, spermidine had the strongest link to a longer life of any nutrient measured. Nearly six more years.

Worn-out proteins. Broken machinery. Cellular debris that accumulates faster every year you are alive.
Autophagy is the process by which every cell in your body takes out the trash. Fasting is the famous way to trigger it. But autophagy slows with age, and the junk it once cleared piles up.
Nobel Prize, 2016. The prize was awarded for discovering how autophagy works.
Worn-out parts, piling up. Autophagy clears them, and spermidine is what switches autophagy back on.
Your body produces spermidine for one reason: to launch autophagy. The deep cellular renewal that hunts down every piece of debris piling up inside your cells, and destroys it.
It activates the exact same renewal pathways as a prolonged fast. Every cell gets the signal to strip out the old, the broken, the spent, and rebuild from scratch.
No hunger. No deprivation. The full power of fasting, from a molecule your body already knows.
Every serving delivers a full 20mg, which meets or exceeds the dosage in every major study linking spermidine to a longer life.
Clean label: only 3 ingredients. Plant-based capsules containing spermidine, organic acacia fiber and organic rice hulls. That is the whole list.
Measured by an independent 3rd-party lab. Tap any brand to see its lab report.
Most spermidine supplements use wheat germ extract, which is roughly 1% spermidine by weight, and it is why two capsules of one brand and two of another can deliver completely different amounts. Plant material varies from harvest to harvest. A pure molecule does not, which is why SPMD-99 is guaranteed to deliver what’s shown on the label.
No wheat, no gluten, free from the nine major allergens.

Every batch is tested by an independent 3rd-party lab, proving it delivers what’s promised on the label.
Left, wheat germ extract, which is roughly 1% spermidine by weight. Right, the pure molecule.
Your hair follicles have two modes: growing and resting. As you age, more of them rest. Spermidine drives autophagy directly in the scalp, clearing the oxidative damage that shuts follicles down. In a placebo-controlled study, it pushed significantly more follicles back into active growth.
Fuller hair. Stronger nails. Firmer skin. One molecule behind all of it.
Microplastics have been detected in the blood of 77% of healthy adults. Based on recent research, you are likely carrying about 7 grams of microplastics in your brain: the weight of a plastic spoon.
When your cells detect nanoplastics, they try to clear them using autophagy. But plastics jam the system. The recycling machinery stalls, mitochondria get damaged, and inflammation spikes.
Spermidine keeps the autophagy going, isolating the plastic particles and continuing the cleanup. It also triggers mitophagy, clearing the damaged mitochondria so they don’t sap your energy.
Spermidine and sulforaphane are two of the only supplements shown to help remove microplastics from the body.
The average person ingests about 20 grams of microplastics every month, the weight of a one-liter water bottle.

I bought SPMD-99 mostly out of curiosity about healthy aging. After a couple of months, my nails seemed less prone to splitting at the edges. I cannot prove the reason, but it is a welcome little observation.

I already have a skincare routine and was interested in something complementary rather than another serum. My skin has looked a bit more even to me recently. I am continuing SPMD-99 while keeping the rest of my routine the same.

My complexion has seemed a little less dull over the past several weeks. I have not changed my moisturizer, although weather and sleep always play a role. I like the idea of supporting my skin as part of a broader health routine.

I chose SPMD-99 for its connection to cellular renewal research, not because I expected to feel something right away. Lately I have been less sluggish in the early evening. I cannot attribute that confidently to the capsules, but I am encouraged.

In a placebo-controlled study lasting 90 days, spermidine pushed significantly more follicles back into active growth. Hair is usually where people see it first. The same process that grows hair back makes nails stronger and skin firmer.
The rest of the work happens inside and you will not feel most of it. The label says take it for a minimum of 4 months and beyond. If you would rather measure it than sense it, run a full panel of blood tests before you start and again after 4 months.

It is linked to nearly 6 years of longer life.

Because most spermidine is barely spermidine.
Most spermidine supplements use wheat germ extract: a big capsule of plant material with roughly 1% actual spermidine, and the amount varies.
