Summary: I truly like flaxseeds because they are 100% loaded with nutrients and, gram for gram, not missing one beat, an excellent and affordable, tasty food option. For me: viva la flax!
1.Where so flaxseeds fit in?
When we talk about food, it’s often about the big items: meat, dairy, nuts, fish, vegetables, and fruit. You know the routine. We should always aim for balanced and healthy eating. We should consider the impact of cholesterol, the good fats, protein (do we have enough?), and fiber. Doing this right can considerably increase the healthy part of your life (“health span”).
When it comes to food, we should look for diversity. We should spice up our meals. Let’s make our salads more tasty. It’s great to find something that is 100% healthy and provides nutrients that aren’t always easy to come by. Avocado is one such product, and so are flaxseeds! Flaxseeds are affordable and provide protein, fiber, omega-3 fatty acids, essential vitamins, and a wealth of minerals.
2. The health wonders of flaxseeds (according to the internet)
Flaxseed may help lower the risk of some cancers, mainly breast cancer. However, this is based on indications and not definitive science yet. They contain lignans, plant compounds that may also contribute to hormonal balance.
Flaxseed does more. It is said to stabilize blood sugar, being rich in both soluble and insoluble fibers. These fibers are abundant in flaxseeds, which can promote digestive health and regularity.
The combination of omega-3 fats, fiber, and lignans may enhance heart health. They lower cholesterol levels. They reduce blood pressure and decrease inflammation.
The omega-3 fatty acids and lignans in flaxseeds may help reduce inflammation in the body. This inflammation is linked to chronic diseases.
3. I take two spoons daily
I consume, on average, 2 tablespoons of flaxseed per day, which is about 15 grams. Flaxseeds are best consumed ground, as whole seeds may pass through the digestive system undigested, significantly reducing their health benefits.
To save money, buy whole flaxseed. Grind it in a coffee grinder. Then, store the ground flaxseed in an airtight container for easy use.
Instead of flaxseeds, you can use flaxseed oil. Still, it is very sensitive to heat and light. Flaxseed oil is best kept in dark glass bottles and stored in a dark, cool place like a kitchen cabinet. It isn’t suitable for high-heat cooking techniques, like frying.
4. So what does flaxseed give you?
One tablespoon of flaxseeds (=7 grams) already provides: complex carbs 2 g, “good fat” 3 g, fiber 2 g and protein 1 g. Not bad at all!
The “good fat” consists mainly of alpha-linolenic acid (ALA), an omega-3 fatty acid, primarily found in plant foods. Flaxseeds are one of the best sources in the plant world for ALA. Flax oil (which I do not use) has double the amount of ALA as the seeds.
One tablespoon of flaxseeds contains two grams of fiber. It might seem modest, but two tablespoons of flaxseeds is already 10% of your daily need. For women, that’s 14%. This is not the place to dwell on the importance of fiber, but just to recap. Most of us do not get enough fiber per day. Yet, it is essential for gut health and bowel movement. So just adding two tablespoons per day to your smoothie or salad is already a good step.
In addition, flaxseed has Thiamine: 10% of the Daily Value (DV), Copper: 9% DV, Manganese: 8% DV, Magnesium: 7% DV, Phosphorus: 4% DV, Selenium: 3% DV, Zinc: 3% DV, Vitamin B6: 2% DV, Iron: 2% DV, Folate: 2% DV
5. But take care in a few specific cases (according to internet)
As the reader knows I am no doctor. On internet I read the following warnings about flaxseeds.
If ground flaxseed or flaxseed oil goes rancid, it may cause cholesterol problems and inflammation. In general, but you have to eat really great quantities, it might cause diarrhea, cramping, gas, and bloating.

6. Which is better, chia seed or flaxseed?
Chia and flax seeds are both very nutritious and offer similar benefits for heart health, blood sugar levels, and digestion. However, flaxseeds appear to have a slight advantage. They are particularly effective at reducing hunger and appetite. Additionally, they lower the risk of certain cancers. Plus, they’re often less expensive.
Time to make a nice salad for my wife. Some lettuce, tomatoes, avocado, shrimps, olive oil, cucumbers, all sprinkled with flaxseeds of course.
Four different drinks daily form the larger part of my diet. The rest is more solid, of course. It consists of nuts and fish, but fish much less than before. Fish can easily lead to the intake of too many harmful substances like heavy metals and antibiotics. I also eat some organic chicken, whole-grain bread and pasta, eggs, goat cheese, and a few pieces of dark chocolate. Plus, of course, the occasional other foods.
A. My four drinks
Homemade vegetables soup (every evening)
Lemons and/or lime juice (morning + during day drink)
Fruit/vegetables smoothie with seeds and supplements (late morning and luncheon)
Collagen/creatine/protein shake (morning)
(note, below I put the links of my earlier blogs I made on the first three drinks).
B. The fourth one? Every morning, half a liter of water mixed with lemon juice. Add 2 x 5 grams of collagen and creatine. Include 25 grams of a “complete” protein (=a protein providing all 21 amino acids).
All three ingredients of my fourth drink are proteins. Yet, collagen and creatine have specific purposes. It differs from the “complete” protein powders due to a different, less complete amino acid composition.
A good collagen powder is rich in certain amino acids. These include glycine, praline, and hydroxyproline. They are important for the body’s synthesis (=production) of collagen and other structural tissues. Nevertheless, collagen is relatively low in “essential” amino acids, particularly tryptophan.
So in short, collagen nor creatine have all the amino acids our body needs. For my protein needs I take, in addition to food (pay attention to protein rich food!) a complete (a full spectrum) protein powder that contains all the existing 21 amino acids, including the 9 so called “essential” amino acids. “Essential” in the sense that the body does not produce them and nutrition is needed to get them. As we know, these amino acids form 1000’s of different proteins. These proteins are better known as the building blocks of life.
C. “Might work, but no harm”-principle
I realize that not all claims about collagen are proven. For me, taking collagen falls in the category: “it does not hurt (except your wallet).” It might actually do some good. Life is short and there are many developments on going. However, one does not have the time to await the result of all research. For that reason I do no mind taking supplements that are promising, but not scientifically proven. It is important though that they should not do harm. Precisely because of potential harm I have decided not to take Omega-3 supplements anymore. https://shakethehealthtree.com/index.php/2025/03/21/21-omega-3-supplements-often-no-need-to-take-them-health-project99/
Ok, one by one. Why collagen? Why creatine? Why a wide range/complete protein?
D. Protein
To start with the last one. From my extensive internet and Youtube based research on protein, I drew main 3 conclusions: 1) most people have a too low intake of protein, especially in the light of the latest insights that go for 1.2 – 1.5 grams of protein per kg body weight. In my case I raised protein intake from 70 grams to 120 grams. 2) Your body can effectively only process about 25 grams per time slot of a few hours. This means that you have to spread your protein intake during the day. That is why I put protein in my smoothie. I also added it to this fourth early morning drink. 3. Make sure that you have a protein of good quality that has all the 21 amino acids. And do not worry if you take a bit too much. It will do no harm, except to your waistline.
Certain claims about creatine have withstood scientific scrutiny. This unlike collagen where studies are still ongoing with only positive indications that collagen might have some positive effect.
Creatine is not a protein. It is a compound related to amino acids. These amino acids are the building blocks of proteins. Specifically, creatine is synthesized (produced) from three amino acids: arginine, glycine, and methionine.
Creatine is stored in the muscles. It is used to replenish “adenosine triphosphate” (ATP), the primary energy carrier in cells. This occurs during short bursts of high-intensity physical activities, such as weightlifting or sprinting. This ability to rapidly regenerate ATP makes creatine a popular supplement among athletes. Bodybuilders also favor it to improve performance and increase muscle mass. Also non-athletes profit as creatine contributes to stronger muscles and improves endurance.
F. Best creatine is creatine monohydrate
There are different kind of creatine. The one most recommended is creatine monohydrate. While there are other forms of creatine available on the market—such as creatine ethyl ester, creatine hydrochloride, and buffered creatine—none have shown to provide the same benefits as creatine monohydrate. It is also this creatine that I take.
G. Collagen
Collagen is a protein found in abundance throughout the body. Often considered the glue that holds the body together, collagen offers many benefits. It supports the skin’s texture and elasticity. It also keeps your joints moving smoothly and much more.
As you get older, however, collagen production starts to diminish, which as we know has very visible results. Our wrinkles were not there at our 20’s nor was our dry skin. This lack of collagen is becoming especially notable in your 50’s and later. Many other factors can also interfere with collagen synthesis (=production). These factors include smoking, sun exposure, and a poor diet.
Fortunately, there are plenty of ways that can help boost collagen levels, some proven, some not. This varies from food, LED masks to using a collagen supplement. In a later blog I will dive deeper into collagen. For now, it suffices to say that both LED masks and collagen supplements might show promising results. An increasing number of tests support this. Nevertheless, there is no established science yet that confirms that certain supplements lead to collagen production in the body. Research is still ongoing.
Emphasizing a nutrient-dense diet is proven to keep higher collagen levels. This diet includes lots of antioxidants and vitamin C. These nutrients can be found in fresh vegetables, fruits, herbs, and spices.
H. Attributed positive effects of collagen
Increasing your intake of collagen is said to offer several benefits. You can do this with foods, collagen supplements or a combination of both. It supports a healthy gut and impacts gut lining integrity. It supports the health of your joints, tendons, and connective tissue, impacting comfort and mobility. It helps to promote healthy hair, nails, and skin, including skin elasticity. It assists in building muscle. Lastly, it supports the health of the heart and blood vessels.
I. Just to know: collagen supplements prompt collagen production
Collagen supplements do not deposit collagen on the desired places in your body. What it does is stimulating your body to intensify collagen production itself. It acts as a signaling molecule to prompt extra collagen production by the body.
J. Safety
Collagen (nor creatine) supplements are not regulated as strictly as pharmaceuticals. The quality and content of collagen products can vary widely. Also important to realize that there is no such thing as vegan collagen. Collagen powder is made from animal skin and bones. I initially took two collagen types, one based on cows products and one based on fish. I switched to collagen made from bovine products alone. Fish-based collagen carries a greater risk of contaminated produce. Most producers from fish based collagen are a bit sketchy on the origin of its material.
K. My experience
I focus on a collagen-friendly diet and take collagen supplements. Occasionally, I use an LED mask, and my wife insists that I apply certain moisturizing ointments. Given how my parents aged gracefully, I likely have good anti-wrinkle genes. However, since I began taking collagen powder, I’ve noticed a clear improvement in my skin—my neck is smoother and tighter, and my face appears more youthful. This change is likely due to the collagen powder, as my diet was already rich in collagen-friendly foods.
This was the description of the last of my four drinks. I hope it inspires you. As promised herewith the links to the other three drinks.
Summary: 1. Omega-3 fatty acids are important for your health; all your cells use them. 2. Most people are deficient, but the solution is easy for most (change of diet, not taking supplements). 3. Taking high amounts of Omega-3 fatty acids is recommended by many on internet, but this is something you really should check with your doctor. 4. Many supplements are of low quality and can work counterproductive. 5. Higher amounts of Omega-3 fatty acids can have unexpected health consequences like atrial fibrillation.
Your body needs the different Omega-3 fatty acids, especially the EPA, DHA and ALA types. They are essential for a broad range of health benefits. These benefits start with the heart and brain and extend to a healthy cellular structure and function. All your cells use them on a constant basis.
The good news is that you get enough if your diet includes fatty fish twice per week (herring, salmon etc) for the EPA and DHA. For the ALA flax seed or a handful of walnuts daily should be sufficient. The half-life ( = time a compound stays active in your body) of EPA and DHA is approximately 3-4 days. This is excellent. It explains why a few helpings of fatty fish per week give you sufficient Omega-3. This is as suggested by health authorities.
So do you need to take supplements? They are among the most promoted and sold supplements by the industry. However, just like vitamin C, they are easy enough to get through a balanced diet. Really think twice and look at your diet before you decide to take a supplement.
If you do not like fish or are allergic to nuts, supplements might be necessary. I say this with some caution. Omega-3s supplements can be of bad quality, and they often are. They might even cause unwanted effects like triggering attacks of heart rhythm issues. These issues include atrial fibrillation, which has happened to me.
In blogs like these it is standard practice to refer the reader to his/her doctor. This is often done as part of one’s “cover your ass” policy. However, in the case of Omega-3, it is advisable to do so. Of course, we hope that your doctor is open-minded. We hope they look at supplements and other alternatives in a welcoming way. Which is not always guaranteed.
The Omega-3 index
Experts typically recommend targeting an Omega-3 index between 8% and 12%. Most Americans have on average 4%, much too low and up to 80% are below the 8%. The Omega 3 index is a blood test. It measures the amount of EPA and DHA found in the membranes of red blood cells. A test above 8% is desirable. The solution of course is not taking a supplement, but to improve one’s diet.
Recommended Intake of Omega-3 fatty acids
Various health organizations suggest around 250 to 500 mg combined EPA and DHA per day for adults. This supports heart health. Of course there are differences between children, men, women, patients etc. The figures I use are rough estimates only.
There is no established upper limit for EPA and DHA from dietary sources. However, supplementation guidelines often recommend not exceeding 3,000 mg (3 g) per day. This is to avoid potential side effects. Some go to 5,000 mg (5 g) per day.
Discuss with your doctor what “excessive” means in your case. Taking up to 5000 milligrams per day is considered safe for most people. However, it is definitely not safe for everyone. If you are like me and are susceptible to atrial fibrillation, more than 1000 mg of combined EPA and DHA per day might already be too much.
For ALA there isn’t a specific recommendation. However, on internet I see the following suggestion: 1,600 milligrams per day for adult men. For adult women, it is 1,100 milligrams per day.
Why take more?
Why should you take more than the recommended least quantities? There is a lot of interesting research going on that indicate (not proven!) that higher amounts of Omega-3 fatty acids can contribute to a longer and more healthy life.
One example from reliable internet sources
According to new research Omega 3 and Vitamins D and exercise slows biological aging by several months. Older adults who took 1 gram of polyunsaturated omega-3 fatty acids from algae slowed biological aging. They mixed it with vitamin D (2,000 international units per day) and 30 minutes of exercise three times a week. This combination slowed biological aging by approximately 2.9 to 3.8 months over 3 years.
While omega-3 alone reduced biological age, the combination of all three interventions had an even greater impact. A reduction of a few months in biological aging may seem modest. However, this could have meaningful public health benefits. These include a lower prevalence of certain age-related conditions.
Further research has also suggested that a combination of omega-3, vitamin D, and exercise may lower the risk of cancer.
But as always, approach these conclusions with caution as further research is needed. Very few claims are 100% scientifically proven.
What I saw on internet are interesting discussions, a lot of promises, but little proven. Treatments are accepted to slow down aging at the molecular level. However, there is no 100% proof that this leads to a longer life. Similarly, there is no guarantee of better health. Still, many hopeful signs.
If you take Omega-3 supplements
Omega-3 supplements are best consumed with meals, particularly meals containing dietary fats, as this enhances absorption.
Check which brands are reputable. Many are not and the supplements they sell are often oxidized and can be damaging to your health. Preferably buy fish oil, not in capsules, in a dark bottle. Store the oil (or capsules) in the fridge, especially when open. You can do that only for 4 weeks. Fish oil is rich in omega-3 fatty acids, which can easily oxidize in heat, light and air
Oil tends to be absorbed better but can be very expensive. You rely on your digestive system to effectively break down the capsule before it can absorb the omega-3. Most brands use pork or beef gelatin, which is very tough and thus harder to break down.
Best sources for Omega-3s fatty acids.
Natural sources should suffice. For EPA and DHA especially cold water fish like herring and wild salmon. Also eggs can contribute. For ALA flax seed, chia seeds, walnuts.
As I said, it is important to know what was the food of the herring or salmon you eat. The nutrition of farmed salmon is very different from the food of wild salmon. As a result, it has much less EPA and DHA.
The same applies to eggs. Eggs from pasture-raised chickens contain 120 mg of DHA and 23 mg of EPA per large egg. This is more than six times the amount provided by the eggs of grain-fed chickens.
For herring (Atlantic), a 100-gram serving typically contains approximately 770 mg of EPA and 1,000 mg of DHA. For salmon (Atlantic, farmed), a 100-gram serving usually provides around 400-700 mg of EPA and around 700-1,000 mg of DHA.
All easy to calculate. Consuming 300 grams of fatty fish per week provides approximately 5,000 milligrams of EPA/DHA. This amount easily puts you above the minimum needed, which is approximately 2,000 to 3,500 milligrams for the week. Add a few eggs and one can be sure not to be Omega-3 deficient.
Half-life
I already mentioned the long biological half-life of EPA and DHA. This means the time it takes for half of a substance to be eliminated from the body.
For EPA the half-life is estimated to be around 37 to 82 hours. Half-life of DHA is much longer ranging approximately from 72 to 144 hours.
Often you read about a preferred ratio of EPA and DHA of 2:1. Achieving this ratio is difficult, especially if you rely on natural sources only. However, it is more important to ensure adequate overall intake of both omega-3 fatty acids. This is more crucial than focusing on the precise ratio of EPA to DHA. The half-life of ALA is not known.
Bio-availability
The bio-availability of nutrients refers to the extent and rate at which they are absorbed and utilized in the body. For EPA and DHA Omega-3 fatty acids EPA and DHA the natural sources tend to have very high bio-availability. When consumed as part of whole foods, they are present in the form of triglycerides, which are well absorbed. (note: Triglycerides are a type of fat (lipid) found in your blood).
Potential Risks of Excessive Intake
Bleeding Risk: Doses at the high end of omega-3 fatty acids (over 3,000 mg per day) can increase bleeding risk. This is because of their blood-thinning effects. This is especially important for individuals taking anticoagulant medications. Like many people I take these.
Immune Function: Some studies suggest that very high doses of EPA and DHA might suppress the immune system. However, this is not typically reached through diet or normal supplementation. A dysfunctional immune response can lead to a viral or bacterial infection.
Gastrointestinal Effects: Not surprisingly excessive amounts may lead to gastrointestinal discomfort, such as diarrhea, indigestion, or fishy aftertaste. This is the case with many supplements.
Vitamin E and Oxidative Stress: High doses of fish oil may increase oxidation levels. This effect is because of EPA/DHA. This can deplete vitamin E. Some supplements include vitamin E to counteract this.
Pregnancy and Breastfeeding: Pregnant or breastfeeding women should be cautious with fish oil supplements to avoid excessive intake. They should also aim to meet recommended levels for fetal and infant development.
Interactions with Medications: Those on blood thinners, aspirin, or high-dose anti-inflammatory drugs should consult with a healthcare provider. Omega-3 can exacerbate their effects.
What is the use of EPA, DHA and ALA?
EPA (Eicosapentaenoic Acid) plays a crucial role in reducing inflammation and is involved in the production of signaling molecules called eicosanoids, which have various important effects on cardiovascular health and immune system regulation.
DHA (Docosahexaenoic Acid) is a vital structural component of cell membranes, particularly in the brain, eyes, and nervous system, where it supports cognitive function, vision, and overall neural development.
ALA (Alpha-Linolenic Acid) serves as a precursor to EPA and DHA, providing an essential source of omega-3s in plant-based diets, and is involved in energy metabolism and various physiological processes, although its conversion to EPA and DHA in the body is relatively inefficient.
