As a result of a directive issued from the US government, from 29th August 2025  the previous de minimis of below $800 no longer applies.
As a result all goods entering the USA now have a tariff applied + an administration fee if sent DDU (delivery duty UNpaid).
It is up to the sending country/provider to collect the taxes from the receiving customer in the USA before any goods can enter and be delivered in the USA.
 
To make this process as simple as possible we have added the tariff at checkout so that all orders can be sent DDP (delivery duty paid). This means that you will not be contacted by anyone regarding duties or have to pay any extra charges such as administration fees and you should not experience any delays with your order.

Customs charges are usually a mixture of VAT, Duty & Customs Clearance. These charges can vary country to country. Any added charges are not the fault of Marine Healthfoods and we do not gain anything from these charges. We currently ship all packages DDU (delivery and duties UNPAID) with exception of the United States. This means your package is usually delivered by local mail carrier at the final destination or you may be required to collect the parcel from the postal facility directly. Your mail carrier may or may not charge duties and taxes. We do not collect taxes and duties during checkout and therefore you are responsible for paying these if you are required. If you have questions regarding how/when duties and taxes are charged, we advise contacting your Customs office directly. Please note border control checks may delay delivery.

We operate a 30-day return policy only if the product has not been opened. If you return it to us a refund minus shipping costs will be issued upon receipt and inspection of the goods.

If there is a problem with your order or product, please notify us by email. For more information, please see our Returns/Refund Policy.

If you receive your order and items are missing please email us. If there are signs of tampering with the package be sure to include this information in your email. We will then investigate and get back to you ASAP.

OysterMax® is pure oyster extract powder encapsulated in a vegetarian HPMC capsule. We do not add fillers, bulking agents, flow agents or any additives whatsoever. Many other brands do this, but our product is 100% pure oyster extract powder. The caviar of oyster supplements!

Packaged in pharma grade bottles & lids, each lid contains 4.8g of integrated non-toxic desiccant to maintain quality throughout shelf life.

OysterMax® is made from oysters of the species Crassostrea gigas, also know as the pacific oyster, harvested along the Irish Coast.

The best time to take OysterMax® is in the morning 30 minutes before breakfast. This is because some breakfast foods that are wholegrains contain phytic acid which inhibits zinc absorption. Also, due to the Vitamin B12 you may also experience an increase in energy levels which could affect sleep if it is taken later so start of day is better.

No, we do not include the shell, we only use oyster meat.

We carry out heavy metal testing, microbiological testing & vitamin/ mineral analysis on each batch.

Good nutrition is vital to optimize epigenetics. Zinc is vital for growth and cell reproduction as are many other nutrients in OysterMax. When the growth spurt happens, making sure they are getting lots of good nutrition to optimize the process. In the early 1900’s height was very much linked to social status and poorer people who could not afford protein were considerably shorted. Officers in the army who typically came from more affluent homes were always taller.
 
While height may be determined genetically, if you have poor nutrition and lifestyle the potential may not realised.  

We use a hard-shell HPMC (hydroxypropyl methylcellulose) capsule for OysterMax. AKG uses a bovine soft gel. Yukon pure uses a fish soft gel.

Here at Marine Healthfoods we do not work off averages/ fortification for our product. We test each batch for real time quantity of vitamins & minerals and update our labels for each batch. As we do not add any artificial vitamins or minerals these values can change throughout the year. We keep our product page for OysterMax® updated with supplement facts for the current batch being sold to better assist our customers when working out what the right amount to order is. All of its nutrients are natural in origin, making them 100% bioavailable. This means they will support your body’s natural mineral and nutrient balance.

AKG is Fish Liver Oil from Longnose spurdog (Squalus blainville) containing naturally occurring alkylglycerols.

The species used in our AKG-200 product is the Longnose spurdog (Squalus blainville) which is fished along the west coast of Europe. It is a commercial species of fish, and the entire animal is utilized. Fresh, dried, salted and smoked for human consumption. The livers, which would otherwise be dumped, are utilized by us to make AKG-200. The sharks are not fished for their livers and this utilization of the whole animal is an improvement on previous fishing practices of the past.  The shark finning industry has raised serious concerns about shark conservation and particularly in the tropics where they are an important apex predator. We are very aware of this, and marine conservation is a big part of our work. 

You can be assured that we are not interested in emptying the oceans and that on the contrary we are doing our best to educate those in the industry on how a sustainable fishery model is best for us all.

Fishing and fisheries do not have to be the enemy. Management, training, education and respect are required to make this a better, more circular economy for all.

Yukon Pure is Salmon Oil from Wild Alaskan Sockeye Salmon (spp. Oncorhynchus nerka) containing naturally occurring vitamin D & Omega fatty acids.
