Does fadogia agrestis increase your testosterone?
Do not use it. There is barely any human evidence that fadogia agrestis raises testosterone, it is not authorised for sale in the EU, and animal studies show damage to kidneys, liver and testes.
Fadogia agrestis is sold online as a natural testosterone booster, but good research in humans is almost entirely lacking. Its popularity comes mainly from animal studies and online influencers, not from clinical evidence.
It is also problematic legally and in terms of safety: in the EU fadogia is an unauthorised novel food and therefore may not be sold as a supplement.
And safety is a cause for concern: at higher or prolonged doses, animal studies show damage to the kidneys, liver and testes, precisely the organ it is supposed to help. In short: unproven, unauthorised and potentially harmful. Do not do it.
Does boron raise your testosterone?
The two randomised studies in men show no effect on testosterone; the only small study that did find a rise in men had no placebo group and just eight participants. If you want to improve your testosterone, boron currently has no reliable supporting evidence.
Is testosterone important for women?
Testosterone is a physiologically relevant hormone for women, with the strongest evidence for sexual desire and sexual function. If you have symptoms consistent with low testosterone levels, it is worth discussing this with your doctor, including the choice of skin-based delivery.
Does using testosterone help if you are over 50, and can it be dangerous?
Testosterone can be worthwhile for men over 50 with a medically confirmed testosterone deficiency, but it is not a treatment for everyone who is getting older: the benefits are real, the risks are too, and a doctor must establish the indication.
Does testosterone decline in men with age, and should you do something about it?
Testosterone really does decline in men with age. TRT is well supported only in men with established hypogonadism and symptoms, primarily for sexual function. If you have symptoms, always have the underlying cause investigated first.
Does tongkat ali actually work for your testosterone?
Do not use it, even though it probably does raise your testosterone. The European food safety authority EFSA found signs that tongkat ali can damage your DNA, precisely at the common 200 mg per day, and it is not authorised in the EU and banned from sale.
Does excess weight really make your hormones worse?
Excess weight disrupts your hormones in multiple ways simultaneously, and this is not a coincidental association. In men, testosterone drops substantially, and losing weight partially reverses that.
