Core Ingredients of Nature Made Fish Oil
Nature Made fish oil primarily consists of a concentrate of omega-3 fatty acids derived from fish oil. The key components of these omega-3s are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are renowned for their heart, brain, and eye health benefits. A typical serving provides a specific amount of these beneficial fatty acids, though the concentration can vary depending on the product, such as the 1000 mg or 1200 mg formulas.
Beyond the essential fish oil, the supplement also contains several other inactive ingredients that form the softgel capsule and act as preservatives. These ingredients are typically gelatin, glycerin, and water, which create the soft and easy-to-swallow casing. Tocopherols, a form of vitamin E, are also added to act as an antioxidant, preventing the delicate fish oil from oxidizing and becoming rancid.
Sourcing and Purification Process
Nature Made prides itself on sourcing its fish oil from wild-caught ocean fish, not from farm-raised varieties. This practice is seen as a way to ensure a higher quality, more natural product. The specific species of fish used may vary but typically include small, fatty fish like anchovies, mackerel, and sardines, which are known for their high omega-3 content.
The most critical part of the process for ensuring safety is purification. The wild-caught fish oil is purified through a process called molecular distillation to remove harmful contaminants that can accumulate in fish from the environment. This includes removing mercury, PCBs, dioxins, and furans to levels below stringent safety thresholds. This purification step is crucial for delivering a clean and safe supplement to the consumer.
Types of Omega-3 in Nature Made Supplements
It is important to note that Nature Made offers fish oil supplements with omega-3s in two different chemical structures: triglyceride (TG) form and ethyl ester (EE) form. The TG form is the naturally occurring structure of omega-3s in fish. The EE form is a concentrated version that results from the manufacturing process. Many of Nature Made's standard formulas utilize the ethyl ester form to provide higher concentrations of EPA and DHA in a smaller capsule. Some products may specify which form is used, catering to consumer preference for concentration or natural structure.
Comparison of Fish Oil Forms
| Feature | Triglyceride (TG) Form | Ethyl Ester (EE) Form |
|---|---|---|
| Structure | The natural form of omega-3s found in fish. | A concentrated, semi-synthetic form created during processing. |
| Concentration | Lower concentration of EPA and DHA per gram of oil. | Higher concentration of EPA and DHA per gram of oil, allowing for smaller softgels. |
| Absorption | Generally considered to have higher bioavailability and better absorption by the body. | Requires enzymatic conversion in the body for absorption. |
| Processing | Minimally processed to retain the natural structure. | Requires additional processing (esterification) to concentrate the omega-3s. |
| Consumer Preference | Often preferred by those seeking a more natural supplement. | Preferred by those who want a higher dose of omega-3s in fewer pills. |
What is the softgel capsule made of?
The softgel capsule that contains the fish oil is another crucial component. Its primary ingredients are typically gelatin, a gelling agent derived from animal collagen, and glycerin, a clear, odorless liquid. Water is also used in the formation of the capsule. For specific dietary needs, such as a vegetarian or vegan diet, consumers must check the label, as standard gelatin is not plant-based. Some products also include a coating to help reduce the common side effect of 'fish burps'. Other potential inactive ingredients can include methacrylic acid copolymer, polysorbate 80, and triethyl citrate, which are used in enteric coatings.
A focus on quality and standards
Nature Made emphasizes quality assurance by having many of its products verified by the United States Pharmacopeia (USP). USP is a non-profit, scientific organization that sets standards for the quality, purity, and potency of dietary supplements. A USP verification seal means that the product has been tested to meet specific criteria, ensuring that the ingredients and dosage on the label are accurate and that the product is free from harmful levels of contaminants. This third-party verification provides an extra layer of trust for consumers.
The importance of antioxidants
As previously mentioned, tocopherols are included in the formula as antioxidants. Fish oil is susceptible to oxidation, which can lead to a less effective product and an unpleasant fishy taste and odor. Tocopherols help to protect the omega-3 fatty acids from degradation, ensuring the oil remains fresh and potent throughout its shelf life. This is a standard practice in the supplement industry to maintain product stability and quality.
A summary of key components
In essence, Nature Made fish oil is a combination of wild-caught fish oil concentrate, rich in EPA and DHA, encased in a gelatin-based softgel capsule. Additional inactive ingredients like tocopherols, glycerin, and water are included for stability, preservation, and structure. The entire process, from sourcing the fish to purifying the oil and encapsulating it, follows strict manufacturing practices to deliver a high-quality, trusted omega-3 supplement.
Conclusion
Nature Made fish oil is made from wild-caught ocean fish, providing concentrated doses of the beneficial omega-3 fatty acids, EPA and DHA. The product undergoes a rigorous purification process to eliminate contaminants such as mercury, ensuring its safety. With the added benefit of being verified by third-party organizations like USP, consumers can be confident in the quality and purity of what is nature-made fish oil made of. For individuals who do not consume enough fatty fish in their diet, this supplement provides a convenient and reliable source of heart, brain, and eye-supporting omega-3s.
