Do your eyes often feel dry or
have a burning sensation?

Approximately 20 million Americans currently suffer from symptoms of dry eye1,2

Symptoms include dryness, burning, redness, or feeling like something is in your eye1,2

Dry eye can cause decreased vision and excess tearing1,2

Dry eye is a disease affecting the tears and ocular surface that results in symptoms of discomfort, visual disturbance, and tear film
instability—this occurs when the surface of your eye cannot maintain a healthy tear film—which may result in potential damage to the surface of your eye.1,2

Healthy tears are critical for maintaining the front surface of the eye and for providing clear vision1,2

Product & Ingredients

Dry eye occurs when a person does not have enough quality tears to lubricate & nourish the eye. Symptoms include dryness, burning, redness or the feeling that something is in your eye.
Pristene is a physician formulated supplement based on clinical studies for healthy tear support. It is made with vegan & natural ingredients clinically proven to show improvement in dry eye signs and symptoms. Pristene is Certified Vegan, non-GMO, and gluten free. It contains significantly more Omega 3s than most dry eye supplements on the market. It also contains Maquiberry, which is an antioxidant shown to support tear fluid production.
Pristene is made with carefully chosen vegan ingredients that are clinically proven to show improvement in dry eye signs and symptoms. The ingredients in Pristene are shown to restore and increase tear fluid production and help produce healthier tears.
Everyone’s physiology is unique and results vary from person to person. You may notice a change in your dry eye symptoms immediately or it may take more time.
Pristene is meant for long term use. Always consult with your doctor before starting any new dietary supplement, including Pristene.
There are no known interactions with Pristene and medications. Please speak with your doctor to determine if Pristene is right for you.
The algal oil used in Pristene is a highly potent, natural, vegan source of the Omega 3 essential fatty acids, EPA and DHA. Because it is made from algae and not from fish oil, you will not experience the fishy burps that are common with fish oil. Algal oil is more sustainable for the world’s fish populations than fish oil. Algal oil is also free of many contaminants that are found in fish oil, including mercury, dioxins, polychlorinated biphenyls (PCBs), and peroxides.
Omega 3’s are essential fatty acids that have been shown to play an important role in helping produce healthier tears. Omega 3’s are not produced by our bodies so we must obtain them through our diet or supplementation.
Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are two types of omega 3 fatty acids. These are not produced by our bodies so we must obtain them through our diet or supplementation. EPA and DHA have been shown to help produce healthier tears.
ALA is an omega 3 fatty acid that converts into EPA and DHA at a very low rate. GLA is an omega 6 fatty acid. Omega 6 fatty acids can often be proinflammatory, and the average american diet contains enough omega 6 so it is not necessary to consume more of this within a supplement.
Maquiberry is a natural berry high in antioxidants. This ingredient has been shown to restore and increase tear fluid production.
The American Dietetic Association and Dietitians of Canada recommend that pregnant and lactating women (along with all adults) consume at least 500 milligrams (mg) of omega-3s, including EPA and DHA, daily. We recommend that women who are pregnant or nursing speak with their doctor to determine the amount of Pristene that is right for them.
The Vitamin E in Pristene contains highly refined soybean oil, which contains no traceable allergens. If you have a soy allergy, please speak with your doctor to determine if Pristene is right for you.
Pristene does not contain any allergens from the 8 major foods or food groups identified by the US Food Allergen Labeling and Consumer Protection Act of 2004 (FALCPA). These ingredients include milk, eggs, fish, Crustacean shellfish, tree nuts, peanuts, wheat, and soybeans.
The shelf life of Pristene is two years from the manufacturing date. This is listed on each bottle.
Pristene is manufactured in California in a cGMP certified facility.
Yes, you can take your multi-vitamin with Pristene. Always check with your doctor before beginning any new supplement.
Yes, we recommend a smaller dose of 1-2 softgels per day. This may vary depending on the age of your child. Please speak with your pediatrician to determine what is right for your child.
