The last two QRMA-tests I have done 2018 and 2020 (a week ago) showed significant deficiencies in nutrients that are involved in blood vessel health: magnesium, copper, silicon, vitamin C, Q10, Vitamin B3 (niacine), vitamin B2 (B2 is reformed to B3 when B3 is low), Vitamin K and the amino acid Lysine.
Consequently I had low values on:
Blood Viscosity
Vascular Resistance
Vascular Elasticity
Coronary Artery Elasticity
Skin Collagen
Either you are sceptical about the results from frequence analysis or not, the results make perfectly sense to me because I have significant varicose veins on my legs and feets, blood pooling redness on the skin, acne, dry skin and easy to get bruise. On POIS wrinkles show up that were not there before.
Since one week ago I have added those nutrients to my SIBO/FODMAP protocol and hope to see improvements but that migh take months. I suspect that I might have bad absorption capability in the small intestine (a hair analysis confirmed this) since I have SIBO.
I also have bough a step-meter and trying to make 10 000 steps each day, but when having POIS I get pain in all muscles involved in exercise (achilles tendon/tights).
But I need to excercise and drink lots of water - otherwise the blood seems to be pooling and symptoms get worse.
