Testosterone Conversion Factor-1

[greatescape]

per avere proprietà anti estrogene se non ricordo male i3c doveva essere 400/600 mg mentre il dim 150mg
c'è chi preferisce il dim per l'assorbimento
anche lo zinco si è dimostrato avere leggere proprietà anti estrogene a dosagi alti pero sopra i 100 mg

[lupin III]

Mai provato il DIM prchè costicchia, sicuramente è interessante.
In ogni caso lo aggiungerei al mix di cui parlavo in precedenza.
Lo zinco sopra i 100mg credo sia poco salubre

lo zinco dell'idi si vende tranquillamente se non mi sbaglio
Zinco Solfato Monoidrato 124,8 mg

equivalente a 200 mg di Zinco Solfato eptaidrato.

avevo letto uno studio sullo zinco che aumentava il testosterone a 200mg se non mi sbaglio
per un breve periodo non fa male credo, è presente spesso in molti testbooster come tutti quelli fatti thehuge
nel multivit della nature best ci sono 60mg

Io ho preso un Daa che dovrebbe essere già tamponato di suo contro gli estrogeni...io ho aggiunto il tribulus, tenuto tutto per 2 mesi...nessun problema, solo un pò di libido in calo durante le primissime settimane, recuperata poi tranquillamente col tempo e forse grazie anche al tribulus.

[LiborioAsahi]

Mah il daa mi interessa, ma c'è questo possibile effetto smorzapalle che un po mi preoccupa.
Comunque secco dubito che il tribulus possa aver influito sulla tua libido.

[lupin III]

Great, pensa pure quello che vuoi ma non credo sia salutare esagerare con lo zinco e in genere coi metalli

anche io.... penso che il mio corpo si sia solo adattato, ed il tribulus non abbia fatto nulla....

sul bugiardino dello zinco dell 'idi che lo puoi trovare online

04.2 Posologia e modo di somministrazione - Inizio Pagina

Nella profilassi della carenza durante la gravidanza e l'allattamento: 1-2 compresse/die;

Nell'acrodermatite enteropatica: 10mg/Kg/die;

Nella terapia delle ferite ed ustioni: 2-3 compresse/die

Nell'acne volgare sono indicate 2-4 compresse/die.

Per garantire un assorbimento significativo di zinco, il prodotto deve essere somministrato a digiuno, almeno un'ora prima dei pasti, con liquidi.

L'impiego di zinco solfato, alla dose di 300 - 1200 mg/die in pazienti affetti da morbo di Wilson, fino a tre anni di terapia, non ha indotto effetti indesiderati.

Neanche in pazienti affetti da acrodermatite enteropatica, l'assunzione a lungo termine di 4,4 - 8,8 mg/kg/die di zinco solfato ha dato luogo a sintomi di tossicità.

anche io so che con i metalli è meglio stare attenti, ma leggendo il bugiardino dell'idi a me sembra sicuro

[greatescape]

lo studio dello zinco solfato come test booster era 3mg di zinco x kg, quindi 80kg=240mg di zinco, aumentava testo totale e libero

[greatescape]

lo zinco dovrebbe essere anche un ai naturale e un anti dht

[greatescape]

io so che i metalli meglio limitarli pero in questo caso mi sembra sicuro, se tu hai qualche info su dosaggi che ne evidenziano sides potresti metterli

Abstract

PURPOSE:

Zinc is a common dietary supplement that is widely believed to have beneficial health effects. To assess the impact of high dose supplemental zinc on genitourinary diseases we analyzed a recent randomized trial comparing zinc, antioxidants and their combination to placebo for complications related to the genitourinary tract.

MATERIALS AND METHODS:

In a further analysis of the recent Age-related Eye Disease Study we examined the data pool for primary International Classification of Diseases, 9th revision codes given for hospital admissions related to urological problems. The Age-Related Eye Disease Study randomized 3,640 patients with age related macular degeneration to 1 of 4 study arms, including placebo, antioxidants (500 mg vitamin C, 400 IU vitamin E and 15 mg beta-carotene), 80 mg zinc and antioxidant plus zinc. Statistical analyses using Fisher's exact test were performed.

RESULTS:

We found a significant increase in hospital admissions due to genitourinary causes in patients on zinc vs nonzinc formulations (11.1% vs 7.6%, p = 0.0003). The risk was greatest in male patients (RR 1.26, 95% CI 1.07-1.50, p = 0.008). In the study group of 343 patients requiring hospital admission the most common primary International Classification of Diseases, 9th revision codes included benign prostatic hyperplasia/urinary retention (benign prostatic hyperplasia), urinary tract infection, urinary lithiasis and renal failure. When comparing zinc to placebo, significant increases in urinary tract infections were found (p = 0.004), especially in females (2.3% vs 0.4%, RR 5.77, 95% CI 1.30-25.66, p = 0.013). Admissions for urinary lithiasis approached significance in men on zinc compared to placebo (2.0% vs 0.5%, RR = 4.08, 95% CI 0.87-19.10). There was no increase in prostate or other cancers with zinc supplementation. A significant decrease in prostate cancer diagnoses was seen in patients receiving antioxidants vs placebo (RR = 0.6, 95% CI 0.49-0.86, p = 0.049). Subgroup analysis revealed that this finding was significant in men who smoked but not in nonsmokers.

CONCLUSIONS:

Zinc supplementation at high levels results in increased hospitalizations for urinary complications compared to placebo. These data support the hypothesis that high dose zinc supplementation has a negative effect on select aspects of urinary physiology.

Zinc lowers high-density lipoprotein-cholesterol levels.

Hooper PL, Visconti L, Garry PJ, Johnson GE.


Abstract

Zinc administration in rats is associated with a rise in serum cholesterol level. This study examined the effect of zinc administration on serum lipoprotein values in man. Twelve healthy adult men ingested 440 mg of zinc sulfate per day for five weeks. High-density lipoprotein-cholesterol concentration decreased 25% below baseline values (40.5 to 30.1 mg/dL). Total cholesterol, triglyceride, and low-density lipoprotein-cholesterol levels did not change throughout the study. The sharp fall of the "antiatherogenic" lipoprotein, high-density lipoprotein, associated with zinc administration supports the concept that zinc ingestion may be atherogenic in man.

"The Tolerable Upper Intake Level (UL) for adults is 40 mg/day, a value based on reduction in erythrocyte copper-zinc superoxide dismutase activity."


The Tolerable Upper Intake Level (UL) is the highest level of daily nutrient intake that is likely to pose no risk of adverse health effects for almost all individuals


Although no evidence of adverse effects from intake of naturally occurring zinc in food was found, the UL derived here applies to total zinc intake from food, water, and supplements (including fortified food). Adverse effects associated with chronic intake of supplemental zinc include suppression of immune response, decrease in high-density lipoprotein (HDL) cholesterol, and reduced copper status.


Immunological Response. Intake of 300 mg/day of supplemental zinc as the sulfate for 6 weeks has been shown to cause some functional impairment in immunological response as well as significantly decreased concentrations of HDL cholesterol (Chandra, 1984)


Lipoprotein and Cholesterol. Two studies (Black et al., 1988; Hooper et al., 1980) have found that zinc at doses between 50 and 160 mg/ day decreased serum lipoprotein and cholesterol concentrations in men. Samman and Roberts (1988), however, reported no depression of HDL concentrations in men at 150 mg/day of zinc and found some indication of a depression of low-density lipoproteins (LDL) in women.


Reduced Copper Status. Reduced copper status has been associated with increased zinc intake (Boukaiba et al., 1993; Burke et al., 1981; Festa et al., 1985; Fischer et al., 1984; Prasad et al., 1978; Samman and Roberts, 1988; Yadrick et al., 1989) (Table 12-7). In all studies in which the interaction of excess zinc and copper was measured, there was a consistent decrease in erythrocyte copper-zinc superoxide dismutase (ESOD) activity, an erythrocyte enzyme indicative of copper status. Yadrick and coworkers (1989) reported this effect after total zinc intakes of about 60 mg/day (50-mg supplement plus 10 mg of dietary zinc) for up to 10 weeks. Although the clinical significance of the depressed ESOD activity is unknown, this marker enzyme is known to be a sensitive indicator of the effect of high zinc levels on copper homeostasis.

Although consequences of zinc deficiency have been recognized for many years, it is only recently that attention has been directed to the potential consequences of excessive zinc intake. This is a review of the literature on manifestations of toxicity at several levels of zinc intake. Zinc is considered to be relatively nontoxic, particularly if taken orally. However, manifestations of overt toxicity symptoms (nausea, vomiting, epigastric pain, lethargy, and fatigue) will occur with extremely high zinc intakes. At low intakes, but at amounts well in excess of the Recommended Dietary Allowance (RDA) (100-300 mg Zn/d vs an RDA of 15 mg Zn/d), evidence of induced copper deficiency with attendant symptoms of anemia and neutropenia, as well as impaired immune function and adverse effects on the ratio of low-density-lipoprotein to high-density-lipoprotein (LDL/HDL) cholesterol have been reported. Even lower levels of zinc supplementation, closer in amount to the RDA, have been suggested to interfere with the utilization of copper and iron and to adversely affect HDL cholesterol concentrations. Individuals using zinc supplements should be aware of the possible complications attendant to their use.
