In the past I ordered a few supplements and I later find out some of these are better to be thrown away. I am very sceptic of supplements now, especially since creatine has caused my hair to thin. There were many sites who claimed this only happens in the genetically susceptible, but this is 100% bs. Everyone has 5a-reductase enzymes, as well as DHT. Creatine causes the first to raise the latter. DHT in turn blocks hair follicles to absorb some nutrients. These sites will list 50 benefits, with only some of them mentioning it might cause hair loss. How responsible of them.
I´ll admit, I took a relatively high dose (5-10g a day), but there were enough sites who claim it would not give any negative side effects. I obviously took it due to the ergogenic benefits.
As you can imagine, this has made me really sceptic of all supplements. Many sites do not list negative side-effects properly, and I intend to put more focus on this issue to prevent other people from making the same mistakes.
So, this post will be a focus on known negative side-effects and safety of certain supplements/herbs. Please add some yourself you are aware of, and share a source or your opinion as well if it is necessary to avoid it. Here are a couple I know:
- All testosterone boosters are bs, with possible exception of stinging nettle and tongkat ali. However,
- Tongkat Ali can cause hair loss as it lowers SHBG.
- Stinging Nettle has a case study of causing gyno.
- Panax even has two case studies of gyno.
- Reishi can cause liver damage in powder form when taken for a month or two (case study).
- Valerian probably is not that toxic, even at long-term but I want to mention there are some case studies about it which had some negative outcomes.
- The spices cassia cinnamon, tarragon, stevia (up to 1,8x body weight in pounds a day max, but perhaps better to avoid), nutmeg (only safe in very low dose), I believe star anise is harmful as well
- Fennel (it is safe, but it can raise estrogen in men. It´s really low in antioxidants anyway so better take in other spices instead.
-Valerian
- Kava had some toxic outcomes.
- Horny goat weed/epimedium, I read something about raising estrogen levels
- Pueraria lobata/kudzu, also read something about raising estrogen levels
- Gotu kola, I read something about it causing liver damage
- Vinpocetine, selfhacked.com was not positive at this at all
- Yerba mate, there was a study which found high carcinogenic polycyclic aromatic hydrocarbons, but this might have been the cause of the way it had been prepared
- Bacopa monnieri had anti-fertility effects in mice studies.
- Turmeric had anti-fertility effects as well, but it has so many other positive benefits that I am willing to take it. The anti-fertility effects are like transient as well.
- Echinacea, astragalus and panax: all immune boosters so probably not good for anyone with certain auto-immune diseases.
- MSM, not good for those who practice methionine restriction
- Inositol, lowers testosterone
- CLA, might cause fatty liver and act pro-inflammatory. Fat burning effects are exaggerated anyway.
Luckily, then there are also a few supplements/herbs/spices I am certain of which are positive:
- Vit D, increases life span. Also limit skin cancer when taken as a substitute for sun-UV.
- Amla, extremely high in antioxidants and vit C, but loses vit C easily as it is water soluble. So not a problem.
- Hibiscus tea, also very high in antioxidants. It has a high manganese count, but up to 1 quart a day can be consumed (nutritionfacts.org has a video on this).
- The other spices which I did not mention. Even though they are safe only for long-term in small amounts.
- Erythritol, the only sweetener in sugar-form which actually good for you.
- Molasses
Then there are a couple supplements I would be really grateful about if anyone knew a certain safety concern/negative side-effect: ashwagandha, schizandra, andrographis, ginsengs, acai, ginkgo, maca, chlorella, lemon balm, astaxanthin, DHEA, melatonin, pycnogenol, rhodiola rosea, devil´s claw, polypodium, bosweilia serrata, cissus, CoQ10, glucosamine, NAC and lavender.
And final as a bonus, what do you guys think of raising testosterone. Does it give serious negative side-effects as well for men?
