Does Jo Mar Labs accept international orders?

Yes, our website now accepts international orders and payments.  We can ship to many different countries around the world, but not all of them.  Some countries have restrictions on Dietary Supplements and do not allow for them to be imported.  If you do not see your country listed in the One-Step check out page or on the Shopping Cart shipping quote feature, we will not be able to ship your order to your country. 

Please keep in mind that – even if we are able to ship to your country – your country may have some restrictions on how much you are able to import.  Please check with your local customs department to ensure that you are able to receive the type and amount of Dietary Supplements you are ordering.  We are not responsible for orders that are returned by customs and the shipping fees are non-refundable once the order has left our facility. 

Lastly, please be aware that it typically take 6 to 10 business days to receive an international order but it may take 3-4 weeks to receive it - depending on your local customs department and that we can only track packages within the United States.  Duties and taxes will be assessed by the receiving county and are the responsibility of the receiving party.

When should I take Amino Acid Supplements?

Since free form amino acids don't require digestion to be absorbed so it's best to take them on an empty stomach either ½ hour before or an hour after eating. Amino acids that are taken on an empty stomach will not have to compete for absorption and you get the best possible results.


What's the best way to take Amino Acids?

Amino acids should be taken with a full glass of water. You need the water to give the body the liquid it needs to transport all of the nutrients to the cells in your body.

Some Amino acids are tasteless and some have very strong flavors and aromas. Flavors can vary from: sweet, tangy, sour, bitter, or like sulfur.

Amino acid powders can be taken sublingually (under the tongue) or mixed in liquid or applesauce. Although some amino acids are tasteless most have tastes that can range from sweet to bitter. So if the taste bothers you we suggest mixing your powder in juice or other non-protein drink or applesauce (applesauce works great with children).

Most amino acid powders are water soluble or semi-water soluble. So to get the best results when mixing your powder into a liquid we suggest putting your drink into a shaker and drinking it with a straw to ensure that you get all of the amino acid powder residue, which can settle at the bottom.


What is the shelf life of Amino Acids?

While amino acids generally don't spoil, they will lose their potency over time. How the amino acids are stored will play a large role in how long they retain their potency. If stored in airtight containers and kept in a cool, dark, dry place, amino acids can last up to 3-5 years but the general optimal potency guidelines please use within 2 years.


Where can I get more technical information on Amino Acids?

You may call or email our knowledgeable Customer Service staff and they can answer any questions you may have regarding any of our products. Although please keep in mind that we are not medical professionals and we CANNOT give medical advice or assist you with your choice of amino acids or the amount to take. We urge you to consult with your doctor, veterinarian or nutritionist for this information. In addition, there are many good books on the uses of amino acids. We have a recommended reading list available to guide you. You may also look at the following pages for more information on Amino Acids and our Blends:

Do you make custom formulations?

Yes, we can mix any custom blend of amino acids for you or your clients. These blends are available in 1000-gram size, packaged in bags or bottles if you prefer. The price is based on the cost per gram needed using our kilo prices plus a $100.00 mixing/processing charge. Formulas over 10 kilos can be encapsulated for an additional charge. Please call us at 1-800-538-4545 for more information.


Do you offer discounts to professionals?

Yes, we offer discounts to professionals along with a wholesale product line sold only to doctors and pharmacies. Case discounts, private labeling, bulk quantities and custom formulations are easily arranged with very low minimums. Please call 1-800-538-4545 for more information or to set up a professional account with us.
