The MAF D+K is a vitamin D complex centered on the most active useful form, D3. It is rounded out with vitamin K2, as well as the minerals zinc and magnesium, which are needed to make vitamin D perform many of its functions.

Why did we choose these nutrients?

Many vitamin D supplements on the market contain only Vitamin D2 found in plants which is much more difficult for the body to use than Vitamin D3 from animals. However, vitamin D3 supplements usually only contain the bare vitamin, devoid of the cofactors that help it work.

  • Vitamin D is essential for promoting bone health and preventing chronic diseases.
  • Researchers show that food sources of vitamin D3 and sunshine each provide uniquely different benefits for the immune system and to our genes.
  • Some studies show that Vitamin D can be used to mitigate SAD and depression and enhance mood and cognitive function.
  • Vitamin D and K work together to reduce carbohydrate intolerance, improve blood pressure regulation. They also play a role in various areas of the metabolism.
  • Vitamin K2 is also important for the function of cellular mitochondria.

Covid-19 / Potential Delays

Due to Covid19 restrictions there can be longer than usual transit times. We will do everything we can to expedite but some things are beyond our control.

Domestic (Within the US)

We offer the following shipping options:

FREE shipping

International (Outside of the US)

International shipping (including taxes and duties) is at cost with our internation shipping agent and we have tried to keep it as low as possible.

Taxes and Duties
The international shipping agent we use will take care of all the duties and taxes that need to be paid at your end. What you pay at the checkout is all that is due until the parcel is delivered to your door. No need to go into the post office to pay excess and no forms to fill in, we take care of all that.

Our products are all manufactured in the USA using premium ingredients and are fully FDA approved for sale. But many countries have their own regulations and requirements. So before we started shipping internationally we did a lot of background checking. Every country we checked with allows the import of small quantities of Vitamin Supplements for personal use. Generally up to six months supply. Although we have done our homework we couldn’t check every country and rules do sometimes change. So if you are concerned you should give your local customs office a quick call to check. Unfortunately we can’t take responsibility if the shipment has customs issues.

How to get cheaper supplements
Although we are working with the most reliable, reasonably priced provider we could find International shipping isn’t cheap, sending things around the world costs money. But there are ways to minimize that cost.

The first thing to do is to order more than one item at a time. If you order three month’s supply in one shipment the shipping cost is split three ways so it becomes much cheaper.

The second thing to do is set up a subscription. Our flexible subscription options are entirely under your control and shipments can be cancelled, delayed (as long as they haven’t already shipped) or even brought forward to match your needs. So you could set things up to ship three months of stock every third month, no need to remember, just when you start to run out another batch will arrive.

Any issues, please email

Due to the overwhelming demand since we launched MAF Supplements, we are now opening the range up to wholesale orders.
