This under-the-radar grain is a nutritional powerhouse — and one of the most potent sources of the omega-3 alpha-Linolenic acid (ALA). Sprinkle flaxseeds over your morning oatmeal for a pleasant nutty flavor, or blend them into fruit smoothies to satisfy a picky palate. Need more ideas?

Omega-3s have been studied in various mood disorders, such as postpartum depression, with some promising results. In bipolar disorder (manic depression), the omega-3s may be most effective for the depressed phase rather than the manic phase of the illness. The omega-3s have also been proposed to alleviate or prevent other psychiatric conditions including schizophrenia, borderline personality disorder, obsessive compulsive disorder, and attention deficit disorder. However, there is still not enough evidence to recommend the omega-3s in these conditions.
Is krill oil better than fish oil for omega-3? Krill oil and fish oil are popular dietary supplements containing omega-3. Krill oil comes from a small crustacean while fish oil comes from oily fish, such as salmon. Both are shown to increase blood levels of omega-3 and have benefits for health.

Fish oil is also commonly used to treat conditions such as Rheumatoid arthritis, high blood pressure, ADHD, menstrual pain, hardening of the arteries or kidney problems. These conditions can be improved by improving blood flow, which omega-3 fatty acids in the blood stream. There is also some evidence that fish oil may help with conditions such as chest pain, liver disease, migraine prevention, gum infections, breast pain, and muscle soreness due to exercise, skin rashes and stomach ulcers.
In some cases, fish oil pills may cause loose stools, nausea, diarrhea, and decreased appetite, fat in the stools, vomiting or constipation. These side effects can be minimized by taking a fish oil capsule that is coated, which is designed to help eliminate the "fish burps" many users complain about. Starting with low doses of the supplement and working up to a full dose can also help minimize side effects. You can also pair fish oil supplements with meals so that they enter your body more slowly, minimizing the risk of side effects occurring.

(How much omega-3 is necessary to increase one’s omega-3 index?  Studies show it can take between 1800 – 2000 mg of EPA/DHA daily to move a person’s index by 4 – 5 percentage points (12). Importantly, this is a much larger dose than you’d get swallowing one or two regular fish oil capsules and could well explain why many traditional omega-3 products fail to deliver results.)
For several years now, the fish oil and Alzheimer’s disease connection has been studied with consistent results. The essential fatty acids vital for brain function that are found in fish oil can not only slow cognitive decline, but can help prevent brain atrophy in older adults. A study published in the FASEB Journal looked at the health effects of four- to 17-month dietary supplementation with omega-3 fatty acids and antioxidants. The findings once again confirm the potential for fish oil to be used as a weapon to fend off the onset of cognitive decline and Alzheimer’s disease. (8)
Fish oil can be consumed in various ways such as capsules or can be included in daily meals. The dosage should not exceed 3 fish oil capsules per day. 1000mg of fish oil contains approximately 300mg omega-3 fatty acids so you can accordingly use the amount of fish oil in your meals. A daily intake of 3000mg or less is safe for all. Pregnant and lactating women can consume approximately 3200 mg per day.
Fish oil is also used for diabetes, prediabetes, asthma, a movement and coordination disorder called dyspraxia, dyslexia, eczema, autism, obesity, weak bones (osteoporosis), rheumatoid arthritis (RA), osteoarthritis, psoriasis, an autoimmune disease called systemic lupus erythematosus (SLE), multiple sclerosis, HIV/AIDS, cystic fibrosis, gum disease, Lyme disease, sickle cell disease, and preventing weight loss caused by some cancer drugs.
