Omega-3s for the heart
The interest arose in the 1960s when it was realized that the Eskimos and the Japanese suffered less from heart problems. And that this could be linked to their high consumption of fish, rich in DHA (omega-3) fatty acids. We are awaiting the results of a study carried out by an Inserm nutrition unit: it tested for five years the effect of supplementation based on B vitamins and omega-3 in 2,500 people who had a heart attack.
Other studies have also shown their role in reducing inflammation, developing neurons and improving mood.
Since cod liver oil is no longer trusted to recharge omega-3s, laboratories are fighting over the origin of the fish oils from which they are extracted. They can come from cold (Antarctica) or warm (Chile) seas. Is their action better? “It doesn’t seem to matter,” says Dr Hanonik. On the other hand, it is important that the oil is safe (compliance with European standards for the level of heavy metals, dioxin, etc.) and that the content of active products is guaranteed (the quantity must be specified). Some laboratories argue that their omega-3 is more easily assimilated, therefore without aftertaste (Oenobiol).
Lutein and xanthine for the eyes
Currently, they are the ones who benefit from the most convincing studies. An antioxidant cocktail based on omega-3, lutein and xanthine has been tested in 4,000 people and has shown a reduction in visual disturbances due to age-related macular degeneration (AMD) by 25%.
Ophthalmologists begin to advise them, from the age of 50/60, in families affected by this disease. Supplements have also been developed to alleviate dry eyes, instead of drops (artificial tears).
Phytoestrogens for hot flashes
These plant substances have a similar activity, but less powerful than that of female hormones. Among them: soybeans, hops, sage, flax and many others, sometimes associated with vitamins and minerals. Above all, we have satisfaction studies (so many women say that it makes them feel good…). It is therefore the doctor’s advice or direct word of mouth that serves as a guide.
Be aware, however, that not all women react the same way to these products. It depends in particular on their intestinal flora. For better efficiency, herbalists advise taking probiotics at the same time. Be careful, these supplements are not recommended for those who have had breast or uterine cancer, and those who have thyroid concerns should avoid soy.
Glucosamine for the joints
Much controversy, no consensus, but research continues to assess the value of products intended to slow the degeneration of articular cartilage. Studies had found a decrease in radiological signs of osteoarthritis (pinching of the joint space) with glucosamine and chondroitin. Others have not found it. Result: No product can claim “prevents osteoarthritis”.
Since then, products containing in addition omega-3 have shown an anti-inflammatory effect on human cell cultures. A clinical study has therefore been scheduled. In the meantime, you can try doing two-month cures three times a year. For Dr Massol, this can improve comfort.
