Introduction to Fish Oil
DHA is highly concentrated in the brain, retina, testicles, and semen.
I’m a big proponent of fish consumption as a source of DHA. I’m such a big fan of fish that I made the cover of my cookbook have Salmon in it.
The Fish Oil That I Take
Some people want to to know which fish oil that I personally take. I’ve tried a bunch of them and this is my favorite.
Health Benefits of DHA and EPA
1) Fish Oil Reduces Inflammation
In one study, men who took DHA supplements for 6–12 weeks decreased the concentrations of several inflammatory markers in their blood by approximately 20% (R).
This suggests that fish oil and aspirin are a good synergy and should be taken together.
Studies show that a dietary supplementation of fish oil lowers the activity of chronic inflammatory and autoimmune diseases including rheumatoid arthritis, Crohn’s disease, ulcerative colitis, psoriasis, lupus erythematosus, multiple sclerosis and migraine headaches (R).
Fish oil may prevent or slow disease progression in individuals with mild inflammatory diseases (R).
2) DHA Improves Cognition
Higher levels of DHA are correlated with improved verbal fluency in older people (R).
A study on healthy young adults suggested that after six months of daily doses of fish oil (Lovaza) improved working memory (R).
Other studies have demonstrated that youth who have a dietary intake of fish have experienced improved reaction time and memory retention (R).
In another study, low doses of DHA supplementation improved memory and attention (R).
Higher DHA levels in middle-aged adults is related to better performance on tests of nonverbal reasoning, mental flexibility, working memory, and vocabulary (R).
3) DHA and EPA Benefit Mood
There is evidence that suggests that taking fish oil alongside a proven anti-depressant could have significant effects (R).
DHA activates the Cannabinoid system, which may be one mechanism by how it improves mood.
4) Reduces Risk of Stroke and Improves Blood Flow to Brain
Fish oil appears to improve blood flow to the brain in healthy individuals (R).
5) DHA Prevents Aggression
The presence of DHA normalizes aggression (R).
DHA reduces aggression during relaxation following periods of high stress (R).
A 6-month study on schoolchildren ages 8-16 years old demonstrated a reduction in several measures of aggression (R).
6) Fish Oil Lessens Joint Pain
7) Fish Oil Reduces Triglycerides and Increases HDL
Both EPA and DHA have the ability to reduce triglyceride levels, most effectively after several weeks of supplementation (R).
Reduction levels range between 15-30% (R).
Other sources of DHA, such as algae oil and krill oil, tend to have the same benefits (R).
8) Omega 3’s Promote Cardiovascular Health
Normalizing the omega-3 to omega-6 ratio is linked with cardiovascular protection (R).
Fish oil supplementation is associated with a significant reduction in deaths from cardiac reasons (R).
However, one study found that, overall, omega-3 supplementation was not associated with a lower risk of all-cause mortality, cardiac death, sudden death, myocardial infarction, or stroke based on relative and absolute measures of association (R).
9) Fish Oil Decreases Risk of Diabetes
A 1:1 omega-3 to omega-6 ratio is linked to a reduced risk of diabetes (R).
10) Fish Oil Promotes Weight Loss
EPA and DHA have the ability to activate receptors in the body that increase metabolic rate (R).
High doses of fish oil can reduce abdominal and fat weight gain (R).
Fish oil increases enzymes in muscle cells, which is associated with fat loss (R).
11) Omega-3’s Speed Up the Healing Process
Fish oil reduces the rate of muscle degeneration (R).
There is evidence suggesting that fish oil aids muscle growth (R).
12) EPA and DHA Benefit Fertility and Fetal Development
Data suggests that fish oil may contribute to reduced reproductive aging and extended reproductive lifespan (R).
High doses of fish oil supplementation improve markers of the female reproductive lifespan in women of normal weight (R).
The fetus of a pregnant woman can benefit from EPA and DHA for development (R).
There is evidence that fish oil may reduce the risk of premature birth and birth complications (R).
Fish oil is associated with larger birth weights (R).
One study suggests that women who take DHA supplements during pregnancy give their babies some degree of added protection against getting common colds (R).
DHA is very likely important in the formation of the acrosome, an arc-like structure on the top of sperm, which is critical in fertilization because it houses a variety of enzymes that sperm use to penetrate an egg (R).
Higher visual acuity after DHA supplementation is a consistent finding in infants born preterm. For infants born at term, the results are less consistent and are better explained by differences in sensitivity of the visual acuity test (electrophysiologic tests being more sensitive than subjective tests) or by differences in the amount of DHA included in the experimental formula (R).
Omega-3 fats are able to pass from mother to fetus, which assists with nervous system development (R).
DHA is critical for development in the first three months of life (R).
Breast milk is a significant source of DHA. A higher concentration of DHA in breast milk is connected with a mother’s diet and supplementation (R).
DHA supplementation should also be added to the formula to promote cognitive development (R).
13) DHA Protects the Eyes
A 1:1 omega-3 to omega-6 ratio protects against retinal angiogenesis, the development of new blood vessels in the eye (R).
DHA is a key component to this protection. With a regular intake of dietary fish oil, protection is nearly definite (R).
14) Omega-3’s Benefit the Kidneys
Omega-3 fats prevent the progression of kidney disease (R).
Supplementation promotes kidney function in those with diabetes (R).
The intake of omega-3 fats is correlated with protection from kidney disease associated with diabetes (R).
15) Fish Oil Protects the Skin
It is believed that this prevention is due to fish oil lessening the suppression of the immune system caused by sunlight (R).
Fish oil reduces the risk of sunlight on the skin and can protect against burns (R).
16) Fish Oil Helps Manage Gastrointestinal Diseases
17) Omega-3’s Promote Thyroid Health
Studies suggest that omega-3 fats increase thyroid hormone signaling pathways in the liver (R).
18) Fish Oil Decreases Infection
There is evidence that fish oil benefits individuals affected by Klebsiella pneumonia bacterial infection (R).
19) Fish Oil Decreases Muscle Fatigue
EPA and DHA improve contractile recovery in muscles (R).
20) Fish Oil Reduces the Risk of Some Cancers
In mice, DHA was found to inhibit the growth of human colon carcinoma cells, more than other omega-3 PUFAs (R). The anti-cancer effect of DHA was caused by a decrease in cell growth regulators.
Fish oil is associated with improvements in clinical and functional parameters in advanced cancer patients experiencing weight loss (R).
Medical studies found that people taking fish oil received higher scores on assessments measuring quality of life (R).
In addition to DHA’s possible anticancer effect, it may also be used as a non-toxic adjuvant to increase the efficacy of chemotherapy (R).
21) EPA Decreases the Effects of ADHD in Children
22) Fish Oil Helps Alleviate Migraine Headaches
Fish oil supplementation reduces the frequency, duration, and severity of headaches (R).
There is evidence supporting that fish oil is beneficial in the treatment of migraine headaches in adolescents (R).
23) DHA is Neuroprotective
It was found that a diet rich in DHA might protect stroke victims from brain damage and disability and aid in a speedier recovery (R).
Accordingly, dietary administration of DHA reduces stroke-induced neuroinflammation in animal models (R).
24) DHA Helps Epilepsy
The use of DHA by persons with epilepsy could decrease the frequency of their seizures. Studies have shown that children with epilepsy had a major improvement, i.e. decrease in the frequency of their seizures, but another study showed mixed results with 57 adults taking DHA supplementation. The 57 subjects demonstrated a decreased frequency of seizures for the first six weeks of the study, but for some, it was just a temporary improvement (R).
25) DHA Helps Detox
DHA helps mount the body’s antioxidant NRF2 response, which helps us detox.
26) DHA Helps Psoriasis
Supplementary treatment with omega-3 fatty acids complements topical treatment in psoriasis, and makes a significant contribution to improving symptoms (R).
27) DHA May be Anti-Aging
A new study found that higher intake of DHA was associated with slower rates of telomere shortening, which is a basic DNA-level marker of aging (R).
Buying Fish Oil
When buying fish oil, the main thing to look out for is that it’s not oxidized, because that can easily happen.
I get the best effect from this supplement.
- Fish Oil/DHA – Has high EPA+DHA, IFOS certified to not be oxidized….
Other potential options:
The recommended daily dosage of fish oil supplements is 1000mg-1200mg. Adults should get at least two servings of oily fish per week, which is equivalent to about 500mg of omega-3 fats. Maximal results occur after approximately three weeks of taking supplements (R).
However, some people respond to high dosages of fish oil.
Seafood is a great source of DHA and EPA. I like to eat wild salmon often, but I still supplement with fish oil.
