There are hundreds of omega-3 fish oil blends on the market today, but fish oil supplements vary significantly as far as the levels of omega-3 in each softgel, the source of these omega oils, and the overall purity of the blend. So how do you pick?
A few Fish Factors to Consider
We recommend you use a quick three-point checklist for picking your omega-3 supplement. Think of it as the PPS system: Potency, Purity, Source.
- Potency: Check the label on your bottle of fish oil softgels for the total milligrams of omega-3, not the total milligrams of oil in each serving. This will be listed in the supplement facts a few lines down and may appear separately as DHA and EPA omega-3’s, two very beneficial omega types.
- Purity: With all the concern about potential heavy metal (such as mercury) and toxin contamination of whole fish, you want to make sure that your fish oil is rigorously purified and independently third-party tested. Look for a high 5-star purity rating on your fish oil.
- Source: Make sure your fish oils are all cold-water sourced, as these fish types offer you the highest levels of omega-3. Also look for krill oil plus omega-3 fish oil. Krill are a great source of omega-3 and among the most abundant crustaceans in our oceans. The oil derived from krill arrives in a specific and highly absorbable phospholipid form.
Why Choose Krill?
Krill are omega-3 and antioxidant powerhouses. The oil from these small creatures is “pre-emulsified” (more easily incorporated into your cells) and packs an impressive nutritional punch:†
- Krill oil occurs naturally in phospholipid omega-3 form, a highly absorbable form of omega-3 for ease of use and incorporation in cells throughout the body. † Phospholipid levels in our cells decline with age, yet they are needed to help maintain cell membranes, and support skin and brain health.†
- Krill feed on high-antioxidant plant sources and so contain the powerful antioxidant astaxanthin. The beauty of nature’s food chain makes this astaxanthin available to you in the krill oil you take.†
ReNew Life’s new Norwegian Gold Krill Omega combines our highest purity fish oils with the power of added krill oil for an ultra-potent omega-3 blend. Just one small softgel a day (no more handfuls of large softgels that can contain up to 50% “filler” oils) provides you with 2x more omega-3 than leading krill oil brands. Norwegian Gold Krill Omega also offers you the highest third-party tested 5-star purity rating plus added antioxidants astaxanthin and vitamin D!
The low-fat diet craze has been popular since the ‘70s when scientists linked a diet high in saturated fat to raised cholesterol levels, and a low-saturated fat diet was found to be protective against heart disease. Somehow, because of the unhealthy qualities of this one type of fat, the entire fat category got a bad rap. Thus began the low-fat diet craze (which actually became the low-fat, high-carbohydrate diet craze that continues to contribute to the highest rates of obesity, diabetes, and heart disease we have ever seen).
The truth is we need fat. It’s one of the three main macronutrients—fat, carbohydrates, and protein—that provides fuel for our body and keeps us running. Every cell in the body is enclosed in a membrane made up of fats. Without fat, our cells cannot run efficiently. But certain fats are better than others, as scientists learned in the early studies investigating fat and heart disease.
The one fat you want to completely eliminate from your diet is processed trans-fat. The trans-fat found in hydrogenated oils (common in processed foods) has been linked to a number of health conditions. It’s best to cut this one out completely. The fat you want to greatly reduce is saturated fat. Although a natural fat, its saturated nature means that it is a stiff molecule, and stiff fats make for stiff cell membranes. This reduces the ability of the cell to maintain fluidity—an important characteristic of a healthy cell.
You don’t have to eliminate saturated fats, but be sure to eat them in moderation. Even better, obtain your saturated fats from coconut oil, a medium chain saturated fat considered a healthy saturated fat due to its shorter chain length and rapid metabolism.
The fats you do need to eat—probably more than you already do—are monounsaturated fats (found in olive oil) and the omega-3 fats (found in fish oil, flaxseed, chia seed, and walnuts). These fats are unsaturated, and contribute to the fluidity of cell membranes, as well as to the regulation of inflammatory response—all health-promoting actions.
A recent study published in the journal Molecular Nutrition & Food Research highlighted the importance of eating fats along with vegetables. The researchers found that the carotenoid nutrients (beta carotene is a carotenoid) found in salads were best absorbed when eaten in combination with monounsaturated fats as opposed to saturated or even polyunsaturated fats. If you have been passing on salad dressing because you want to cut down on fat, you’re better off adding fat—use a vinaigrette made with olive oil. This week, add some extra virgin olive oil to your veggies and remember that fat is a nutrient—not the enemy. Just choose the right fats.
