I've been taking HeartTech prophylactically for a year or so. BUT I have one large concern now that I\'ve done more research. I see on your website here a testimonial of one woman taking fish oil capsules plus a double-dose (at least) of Heart Tech.
I've been doing the same (except I take cod liver oil in liquid form, not capsule and only do 2t's of HeartTech daily). I've read in a medical journal that it's a BAD practice to take more than 10,000 units of Vita A because the body stores it. So combining fish oil and Heart Tech, particularly in the dosages this testimonial suggests, is dangerous! I really, really think you have to direct your customers about this overdosage possibility and suggest either Cardio-C to persons who prefer their Vita A in a more natural form --fish oil. I came online today to see if I could ind HeartTech w/out the add'l suppl (w/just the Proline, Lysine). Fortunately I see Cardio-C but you really shouldn't have this testimonial describing what I believe is an overdosage of vita A! Thx. C. K.
Dear C. K.,
This is a great question, however, your informaiton about vitamin A is wrong, no matter what medical journal you may have read it in. The public has been lied to about vitamin A. The medical doctors and the dieticians are trained wrong. The major reference for this assertion is the 1996 book VITAMIN A DEFICIENCY by Alfred Sommer, Keith West, et. al, Oxford Press, ISBN 0-19-508824-7.
If you really want to learn about vitamin A and read an authoritiative book, this is it.
The reason the liver stores this important vitamin is so it can release vitamin A into the blood stream during periods of low intake. If it could not do that, you would die during periods of vitamin A shortage- after you first went blind.
Linus Pauling in his 1986 book entitled HOW TO LIVE LONGER AND FEEL BETTER recommended between 20,000 iu and 40,000 iu of vitamin A daily. The upper daily limit may vary among individuals, but it is probably well above 80,000 iu per day, and NO ONE HAS EVER DIED FROM A VITAMIN A OVERDOSE (Reference http://www.vitamincfoundation.org/journ ... html#DAVIS ),
If one begins to experience any "toxic" effects, they may simply cut back, and any ill effects go away. Vitamin A "toxicity" is not like prescription drug toxicity - which can kill you.
We trust Linus Pauling and Roger J. Williams. Over the years we have followed many of these so-called studies that blame vitamin A for "birth defects" or "bone dimineralization", etc.. These studies are bogus. (Vitamin A, works with vitamin D and vitamin K for instance. Its function seems to be to clean out old bone for new bone to grow. If a study focuses on part of the bone rebuilding process, the idiots can conclude that vitamin A is bad for bones.)
Some people experience benefits with HeartTechnology that we don't see with people taking the other major ingredients separately. I think the vitamin A may explain the HT success.
p.s. As the discussions at this forum have pointed out, there may be an issue with certain brands of "cod liver oil." T hese products may cloud the issue, and it is reported here that certain brands may cause problems, probably due to impurities.
