Who Is It Designed For?
If your skin looks more tired than you feel, if your hair is thinner than it used to be, if your knees and back are stiff in the morning, or if your eyes feel dry and strained after a day of screens — this was made for you.
Ageing starts in your cells, not on your skin. Every day, sun, stress, screens, pollution and time create free radicals that wear your cells down. That wear shows up in four places first: your skin, your hair, your joints and your eyes.
Creams, serums and eye drops work on the surface for a few hours. This works from the inside, every day: 12 mg of natural astaxanthin from microalgae, in two small oil softgels.
Made for women and men who want to look rested, move freely and see comfortably — with one simple routine instead of four products.
The 6 Things This Formula Was Built For
One ingredient, six jobs — each one mapped to a place you notice your age. Not a 30-ingredient blend. Not a 4 mg capsule.
1. Antioxidant protection where it counts. Astaxanthin is fat-soluble and sits inside the cell membrane, the layer where oxidative wear begins, helping protect your cells from free radicals.
2. Brighter, firmer-looking skin. Supports skin moisture, elasticity and a natural glow from the inside, and helps your skin cope with everyday sun (keep your sunscreen on).
3. Stronger, fuller-looking hair. Helps protect hair follicles from the oxidative stress that weakens strands, for less shedding over time.
4. Easier, more comfortable joints. Supports joint and muscle comfort and recovery, so mornings and workouts feel less stiff.
5. Comfortable, rested eyes. Astaxanthin reaches the eye, supporting eyes that feel less strained and dry after long screen days.
6. Clean and simple. Natural astaxanthin from microalgae in an oil softgel. Vegan softgel, no fillers, no soy, dairy, gluten or sugar, third-party tested.
How It Works
Free radicals are unstable molecules your body makes every day — more with sun, stress, screens, smoking, sugar and age. They damage cells through oxidative stress, and over the years that wear becomes visible. Most ageing isn't about the cream you use. It's about what's happening inside your cells.
What's actually happening:
Free radicals attack the fatty membrane around each cell → cells work less well.
Collagen and elastin break down faster → skin looks duller, thinner and less firm.
Hair follicles, joint tissue and the eye are rich in fats → they show the wear early.
Why what you've tried hasn't fixed it:
Creams and serums work on the surface for a few hours.
Vitamin C and other water-soluble antioxidants don't stay in the fatty layer where the damage happens.
Most astaxanthin capsules are 4 mg, often synthetic, or a dry powder that absorbs poorly.
Separate pills for skin, hair, joints and eyes add up fast, in cost and in effort.
How Syntro Astaxanthin works differently. It's the red pigment a microalga makes to protect itself in full sun — the same pigment that turns wild salmon and flamingos pink:
✓ 12 mg natural astaxanthin per daily serving — the amount used in skin and eye studies, three times the common 4 mg.
✓ From Haematococcus pluvialis microalgae — natural, not synthetic.
✓ Fat-soluble, in an oil softgel — sits inside the cell membrane and is built to absorb with a meal.
✓ Clean — vegan softgel, no fillers, third-party tested.
Two softgels a day. That's it. One routine for skin, hair, joints and eyes.
What to Expect — Your First 90 Days
Here's what customers typically report. Astaxanthin builds up in your tissues gradually, so give it two to four weeks of daily use for the first changes — some notice sooner.
Days 1–14 — the building phase. Astaxanthin starts to build up in your cells. Many people first notice eyes that feel less tired after screens and skin that looks a little less tired in the morning.
Weeks 2–4 — the glow phase. Skin starts to look brighter and more hydrated, and mornings feel a little less stiff.
Weeks 4–8 — the visible phase. Skin looks firmer and more even, joints feel easier on stairs and after workouts, and many notice less hair in the brush.
Days 60–90 — the new-normal phase. The support compounds: fuller-looking hair, steady comfort, skin that looks rested. This is when people stop thinking of it as a supplement and start thinking of it as their routine.
The sun, stress and screens don't take a day off. This protects your cells every day you take it. That's why most customers keep going past the first pouch.
How To Use
Take two softgels a day with water, ideally with a meal that contains some fat — astaxanthin is fat-soluble, so it absorbs best with food. That's the whole routine.
Each pouch is 60 softgels, a 30-day supply. Consistency is what makes the difference: many people notice their eyes and skin within 2–4 weeks, with joints and hair building over 4–12 weeks. Store in a cool, dry place away from direct light.
This is a dietary supplement, not a medicine. Do not exceed two softgels a day. Not for children. If you are pregnant or breastfeeding, take medication (especially blood thinners or blood-pressure medication) or have a medical condition, talk to your doctor first. Your stool may look slightly reddish — that's the natural pigment and it's harmless.

What customers are actually saying
“I'd spent a fortune on serums. Five weeks into these, a friend asked if I'd been on holiday.”
Catherine M., 52 · Skin glow
“Less hair in my brush every morning. By month three my hair felt stronger than it had in years.”

Michael T., 63 · Eye strainIt's Not Your Cream. It's Your Cells.
Dull, Tired Skin & Fine Lines After 40
Astaxanthin sits inside your skin cells' membranes and helps protect them from the oxidative stress that breaks down collagen, for skin that looks brighter, firmer and more rested.
Thinning Hair & More Hair in Your Brush
Hair follicles are under constant oxidative pressure. Daily antioxidant protection helps keep strands stronger, so you see less shedding and fuller-looking hair over time.
Stiff Knees & Back in the Morning
By helping your body handle everyday oxidative stress in joint and muscle tissue, astaxanthin supports comfortable movement and faster recovery, so stairs and workouts feel easier.
Dry, Strained Eyes After Screens
Astaxanthin is one of the few antioxidants that reaches the eye, supporting eyes that feel less tired, dry and strained after long days at a screen.

Your First 90 Days on Syntro Astaxanthin
Two weeks in, my skin already looked less tired in the morning. I didn't expect to notice anything that early.
Days 1–14
The building phase
Astaxanthin starts building up in your cells from day one. Most people first notice eyes that feel less tired after screens and skin that looks a little less tired in the morning.
- ✨ Skin looks less tired
- 👀 Eyes feel rested
- 🌿 An easy routine
Around week four I noticed less hair in my brush. I'd been counting, honestly. That's when I knew it was doing something.
Weeks 2–4
The glow phase
As astaxanthin builds up, skin starts to look brighter and more hydrated, mornings feel less stiff, and hair follicles are better protected from oxidative stress.
- ✨ Brighter-looking skin
- 💧 Better hydration
- 🌅 Easier mornings
Six weeks in, I took the stairs at the office without thinking about my knees. That hadn't happened in years.
Weeks 4–8
The visible phase
This is when it shows: firmer, more even-looking skin, joints that feel easier on stairs and after exercise, and less hair in the brush. Many people say friends notice before they do.
- 💪 Easier joints
- ✨ Firmer-looking skin
- 💇 Less shedding
Month three. Friends keep asking what I've changed, and my answer is two softgels with breakfast.
Days 60–90
The new-normal phase
The sun, stress and screens are there every day, and so is the protection. Kept up, the support compounds — rested-looking skin, fuller-looking hair and comfortable joints become your normal. This is why most customers keep going past the first pouch.
- 📈 Results that last
- 🌿 One simple routine
- 🔁 A habit you'll keep
Not a Cream. Not a 4 mg Capsule.
Syntro Astaxanthin
Creams & Low-Dose Capsules
Made For One Job: Protecting Your Cells
Most people blame their age, their genes or the wrong cream. Usually it's oxidative wear building up inside the cells, and creams can't reach it. Syntro Astaxanthin isn't a cream and it isn't a 30-ingredient blend. It's 12 mg of natural astaxanthin that protects your cells from the inside, every day. Here's what customers report after 4 weeks.

Questions About Syntro Astaxanthin
What is astaxanthin, exactly?
Astaxanthin is a natural red pigment made by a freshwater microalga, Haematococcus pluvialis, to protect itself when it's stranded in full sun. It's the same pigment that gives wild salmon, shrimp and flamingos their colour.
Unlike most antioxidants, it's fat-soluble and spans the whole cell membrane, the fatty layer where oxidative wear begins, and it reaches tissues such as the skin and the eye. In lab tests its antioxidant activity is many times that of vitamin C or vitamin E. Syntro gives you 12 mg of the natural form a day, in an oil softgel.
Is this the same astaxanthin that's in salmon feed?
No. Most astaxanthin made in the world is synthetic, produced from petrochemicals and used mainly to colour farmed salmon. Syntro uses natural astaxanthin extracted from Haematococcus pluvialis microalgae, the form used in human studies.
It's also 12 mg a day, three times the 4 mg many supplements stop at, and it comes dissolved in oil so it's built to absorb.
Will it help my joints, or just my skin?
Both, for most people. The same oxidative wear that dulls your skin also affects the tissue in your joints and muscles, so many customers who start for their skin are surprised that stairs and workouts feel easier too — and the other way round.
Give it 4–8 weeks of daily use for joints. It isn't a painkiller and it doesn't replace anything your doctor prescribes — if you have severe, sudden or swollen joint pain, see your doctor.
Can I take this with my medication or other supplements?
It can generally be taken alongside most vitamins and supplements, including collagen, fish oil and multivitamins. If you take prescription medication — especially blood thinners or blood-pressure medication — or have a medical condition, check with your doctor first. Never stop or change a prescribed treatment without your doctor.
Is this a cream, a beauty pill or a medicine?
It isn't applied anywhere and it isn't a medicine. It's a daily dietary supplement — two small softgels of natural astaxanthin — that supports your skin, hair, joints and eyes from the inside. Creams and eye drops work on the surface for a few hours; this supports your cells every day.
What's actually inside it?
Per serving of two softgels: 12 mg of natural astaxanthin from Haematococcus pluvialis microalgae extract, in a carrier oil, in a vegan softgel. No fillers, no soy, dairy, gluten or sugar, no artificial colours or flavours. 60 softgels per pouch, a 30-day supply. Third-party tested for purity and potency.
Is it safe? Are there side effects?
Natural astaxanthin is well tolerated by most people. Some notice their stool looks slightly reddish — that's the natural pigment and it's harmless. Take it with food and don't exceed two softgels a day. It isn't for children, and if you're pregnant or breastfeeding, take medication or have a medical condition, talk to your doctor before you start.
I've already tried other things. Why would this be different?
Because most of what you've tried works on the surface, or never reaches where the wear happens. Creams and serums sit on top of your skin for a few hours. Vitamin C is water-soluble, so it doesn't stay in the fatty membrane of your cells. Most astaxanthin capsules are 4 mg, often synthetic, or a dry powder that absorbs poorly. Syntro gives you 12 mg of natural astaxanthin from microalgae, in oil, built to absorb with a meal — and it covers skin, hair, joints and eyes in one routine.
How quickly will I notice a difference?
Many people notice their eyes feel less tired and their skin looks brighter within 2–4 weeks. Joint comfort and firmer-looking skin usually build over 4–8 weeks, and hair over 8–12 weeks, because hair grows slowly. Full results build over 60–90 days of daily use — and you have 90 full days to decide, risk-free.
How do I take it?
Two softgels a day with water, ideally with a meal that contains some fat, as astaxanthin is fat-soluble. Each pouch is 60 softgels, a 30-day supply. Store it somewhere cool and dry, away from direct light.
Do I need to keep taking it?
The sun, stress, screens and time don't take a break, and neither does oxidative wear. Most customers keep taking it to hold on to their results; stop, and the support tends to fade over the following weeks. That's why the 3-pouch option, a full 90 days, is the most popular.
How fast is delivery?
Orders leave our warehouse within 1 business day and most arrive in 3 to 5 business days. Free shipping on every order, and you'll get tracking by email the moment it ships.
