Astaxanthin, Sea Buckthorn and Seven More: OptiPlax Marine Formula
One capsule a day, built almost entirely from the ocean: astaxanthin from Haematococcus microalgae, sea buckthorn oil, kelp, wakame, chlorella, spirulina and Ecklonia cava in a single 500 mg marine blend. If screens are a large part of your day, this is the formula written for that life — and here is exactly what is in it, what it costs and where to get it.

One check before you order: iodine and your thyroid
Speak to your doctor first if you have any thyroid condition
Kelp, wakame and Ecklonia cava are brown algae, the richest dietary source of iodine there is. Iodine is an essential nutrient the thyroid depends on, and for most adults a marine formula is simply part of a varied diet. But if you have a thyroid condition, thyroid nodules, or take levothyroxine, iodine intake is something your doctor manages — take the ingredient list to them before you start.
Our kelp guide explains where the iodine in seaweed comes from and why the amount varies between species and harvests.
What it is
OptiPlax is a once-daily capsule, thirty per bottle, containing a 500 mg proprietary blend of nine components — eight of them marine, plus sea buckthorn oil. The label positions it around vision support, clarity and focus.
Two label details are easy to miss. The capsule shell is gelatin, so despite being an all-algae formula it is not vegetarian or vegan. And the other ingredients are brown rice flour and silicon dioxide — ordinary fillers and a flow agent.
It is a dietary supplement for daily use — a food product, not a medicine.
The nine ingredients, and what each one brings
Two of the nine are the headline actives with eye-specific trial work behind them. The other seven build out the marine nutrient base around them.
| Ingredient | What it contributes |
|---|---|
| Astaxanthin 2% | Yes, some. Small trials on screen-related eye fatigue at 4–12 mg daily. Reviewers call for larger replication. |
| Sea buckthorn oil | Yes. Randomised placebo-controlled dry-eye trials — at roughly 2 g daily, far above what a shared blend supplies. |
| Kelp powder and extract | Standardised to 10% fucoxanthin, the brown-algae carotenoid studied for metabolic support. Also the formula’s iodine source. |
| Wakame | An edible seaweed contributing fucoxanthin, fucoidan and trace minerals. |
| Ecklonia cava | A Korean brown alga unusually rich in phlorotannin polyphenols, with laboratory work on retinal cells. |
| Chlorella | A nutrient-dense green microalga used as a whole-food source of chlorophyll and protein. |
| Spirulina | One of the most widely eaten microalgae in the world, rich in phycocyanin and B vitamins. |
| Nori yaki powder | Roasted nori, the same seaweed used for sushi, adding minerals and marine polyphenols. |
Astaxanthin and sea buckthorn oil do the heavy lifting, and both are genuine research subjects rather than label decoration. The marine base around them is what makes this a different proposition from the standard vitamin-and-mineral eye tablet.
How it differs from a standard AREDS-style tablet
Most eye supplements on the shelf are built to the same template: vitamins C and E, zinc, copper, lutein and zeaxanthin — the AREDS2 formulation studied by the US National Eye Institute in people with established macular degeneration.
OptiPlax is deliberately a different proposition. It is a marine-algae formula built on astaxanthin, sea buckthorn oil and brown-algae polyphenols — a carotenoid and polyphenol route rather than the vitamin-and-mineral one, and a genuinely active area of nutrition research.
Which one is right for you
If an optometrist has specifically recommended an AREDS-type formulation, follow that advice — it was designed for a particular clinical situation. If you are a healthy adult looking for a daily marine antioxidant routine around long screen days, that is the job OptiPlax is built for. Our eye health guide covers both routes.
How it is taken
One capsule daily. Thirty per bottle, so a bottle is a month.
The label does not specify with or without food. Taking it with a meal containing some fat is the more sensible default here: astaxanthin and sea buckthorn oil are both fat-soluble, and absorption of fat-soluble compounds is markedly better with a meal than fasted.
Keep your eye exams — and use this alongside them
A daily marine formula belongs next to the basics, not instead of them. Two habits do the heavy lifting, and both are worth keeping while you take it.
Book the routine eye test. Glaucoma and diabetic retinopathy are silent in their earliest and most treatable stages, which is exactly why the appointment exists. Anything sudden — a change in focus, new floaters, pain — belongs with an optometrist, not a supplement.
Wear the right glasses. If print is drifting further away than it used to, that is the lens of the eye changing with age and an optician fixes it in one visit. This formula is a daily nutrient routine around long screen days, and it works best when the prescription is right.
Same-day attention needed
Sudden vision loss, a curtain or shadow across your field of vision, a sudden shower of floaters or flashes, eye pain with redness or halos around lights, or sudden double vision. Floaters and flashes can indicate retinal detachment; painful red eye with halos can be acute angle-closure glaucoma. Neither waits.
Who should not take it
- Any thyroid condition, nodules, or thyroid medication. The single most important exclusion, because of the three brown seaweeds.
- Pregnancy and breastfeeding. Iodine requirements change and excess is harmful to the developing thyroid. Use a prenatal supplement with a measured iodine dose.
- Anticoagulants. Several seaweed polysaccharides have been studied for effects on coagulation, and chlorella is high in vitamin K.
- Phenylketonuria. Spirulina is high in phenylalanine.
- Autoimmune conditions or immunosuppressants. Spirulina and chlorella have both been studied for immune effects.
- Vegetarians and vegans. Not a safety issue, but the gelatin capsule rules it out.
The formula, ingredient by ingredient
Each guide below was written independently of this product, and says where the evidence is thin.
Astaxanthin
Haematococcus pluvialis
The red carotenoid that makes salmon pink — and the most-studied single ingredient in eye-support formulas.
Kelp
Laminaria japonica and related species
The large brown seaweed behind kombu stock — nutritionally useful, and the single biggest iodine source in any diet.
Wakame
Undaria pinnatifida
The seaweed in miso soup — lower in iodine than kelp, and one of the world’s most invasive marine species.
Chlorella
Chlorella vulgaris
A single-celled green alga sold as a "detox" supplement — with a cell wall that creates a real quality problem.
Ecklonia Cava
Ecklonia cava
A Korean brown seaweed studied for phlorotannins — polyphenols that only brown algae make.
Spirulina
Arthrospira platensis
Not an alga at all but a cyanobacterium — nutrient-dense, and with one contamination risk worth taking seriously.
Sea Buckthorn
Hippophae rhamnoides
An orange berry with an unusual fatty acid — omega-7 — and the best dry-eye evidence in the formula.

One capsule a day with lunch and I am done — the easiest supplement routine I have had. A bottle lasts the month as described.

Ordering was straightforward and it arrived quicker than I expected. The marine-algae angle is what made it interesting to me.
★★★★★
Small capsules, no aftertaste, easy to keep on the desk and remember. Bought the three-bottle set second time around.
