A Fat Your Body Needs

There are good fats and bad fats, but omega 3 fatty acids are a fat that you absolutely must have. Did you know that adding omega 3 to your diet has been identified as one of the 12 modifiable behaviours that can contribute to increased longevity? Doctors, scientists and nutritionists all agree: omega 3 is crucial for wellness. No wonder it’s a best selling supplement!

Omega 3 is considered essential because the body can’t produce it – you can only get it from diet or supplements. Mannatech’s Omega 3 with Vitamin D₃ capsules are the best choice with;

  • Over 1000 mg of highly concentrated EPA and DHA per serving.
  • Made from one of the highest-quality fish oils available, for ultra-purity.
  • Pleasant orange flavour in an easy to swallow gel capsule.
  • Contains 4 mcg of Vitamin D3, a natural and preferred source of vitamin.


What are EPA and DHA?

EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are considered the two most important omega-3 fatty acids. They are essential nutrients which means they must be obtained through your diet. EPA and DHA are found in many of the body’s organs and tissues and are vital to long-term health. They are found naturally in fish, especially cold-water fish. EPA and DHA are the most-often-studied omega-3 fatty acids and are considered to be very important to health.

What are the best sources of omega-3 fatty acids?

The best sources of omega-3 fatty acids are cold-water, fatty fish such as salmon, mackerel, sardines and anchovy. These cold-water fish provide rich amounts of EPA and DHA, which are the long-chain fatty acids believed to be responsible for most of the health benefits associated with omega-3s. Small cold-water fish are also preferred because they provide a natural balance of both EPA and DHA with less risk of mercury contamination. When it comes to obtaining omega-3s through the diet, one should note that not all fish are rich in omega-3s; farm-raised fish that are grain-fed provide omega-6 fatty acids, further contributing to the unhealthy imbalance of omega-6 to omega-3. Supplementing with fish oil is a convenient and safe way to add omega-3s to your diet.

Why did Mannatech decide to add vitamin D to its omega-3 product?

Vitamin D was added to Mannatech’s omega-3 product for a number of reasons. Most importantly, and much like the case with omega-3s, an enormous amount of recent research and data suggests that not only are most people deficient in vitamin D, this deficiency may also be having a significant impact on long-term health. In addition, our omega-3 fish oil product perfectly complements vitamin D because both products are oil-based and can be combined into a single, easy-to-take gel capsule. Finally, vitamin D is a fat-soluble vitamin that can be better absorbed when taken or combined with another fat- or oil-based food or supplement, such as omega-3 fatty acids from fish oil.

Is Omega-3 with Vitamin D3 suitable for vegetarians?

Currently, omega-3 supplements that provide higher and balanced amounts of concentrated EPA and DHA are fish derived. Omega-3 with Vitamin D3 is derived from fish oil and lanolin and is contained within a capsule sourced from fish gelatin.

If I’m currently taking other Mannatech health products, do I really need omega-3s and vitamin D?

Yes. Omega-3 fatty acids and vitamin D are essential nutrients and are necessary in order to ensure long-term health. No other Mannatech health product currently provides an adequate amount of omega-3 fatty acids, so unless you’re eating the appropriate species of fish on a regular basis, you should supplement with Omega-3 with Vitamin D3.

Can I take Omega-3 with Vitamin D3 if I’m currently taking medications or being treated by a doctor?

You should consult with your physician before taking this product if you are pregnant, nursing, taking medications, have a health condition or are planning a medical procedure. Mannatech’s Omega-3 with Vitamin D3 is natural and safe, but because quality omega-3 products can be very effective they may interact with other medications.

Does Omega-3 with Vitamin D3 contain vitamin A?

Mannatech’s Omega-3 with Vitamin D3 does not contain a measurable amount of vitamins A. The vitamin A in some fish oil products comes primarily from the livers of fish. The oil in Omega-3 with Vitamin D3 is made from the whole fish. The livers of these small cold water fish are very small, so there are only trace amounts of vitamin A in them. Once the oil goes through the molecular distillation, most of the remaining vitamins A is removed.

Why didn’t Mannatech use a plant-sourced omega-3, like flaxseed?

Plant-sourced omega-3s provide alpha linolenic acid (ALA), which has a shorter fatty acid chain than EPA and DHA. While ALA is healthy and beneficial, most of the benefits associated with consuming omega-3s are related to increased consumption of the longer-chain fatty acids EPA and DHA. ALA can be converted to EPA and DHA by an enzymatic process inside the body, but the body is not very good at this process, and the conversion occurs at such a low rate that you would need to consume large amounts of ALA in order to satisfy your EPA/DHA requirements.
