You don't know what your really getting, and can be unsafe!!
Their product pages leave out critical information about the safety and nature of the extract such as standardization or ratio concentration, and sometimes the correct genus species, if it is a botanical. Some products may be unsafe, like their Stevia extract (cheaper steviosides with bitter aftertaste) which is not the same type as the GRAS-approved (Generally Recognized As Safe, FDA) rebaudioside form sold in the grocery stores (no bitter aftertaste- this is how you can know the difference). Rebaudiosides have no affect on blood pressure or blood sugar, but steviosides are documented to lower blood sugar and blood pressure. This may seem good, but it lowers blood sugar by reducing ATP in the intestinal cells which downgrade the energy production and ability to transport nutrients from the intestines into the blood (reduced absorption). This can possibly cause malabsorption, loose bowels, electrolyte imbalances. Steviosides are documented to have side effects such as dizziness, headache, and digestive problems (all of which I experienced until I went off this bad type of stevia). Bulksupplements.com negligently fail to list this critical information about this containing steviosides on the product page and will only reveal what is on the suppliers COA if you send them a message. Most people are unsuspecting of any harm and might think this is the stevia approved by FDA for use as a sweetener, but no this is not the same form. Most people do not have enough of the in-depth scientific background needed to know what is safe or unsafe, or cause side effects, this allows many people to potentially be harmed.
I also ordered their Wild Jujube extract thinking I was getting one derived from Wild Jujube Seed which is used traditionally to help with sleep, but what I ended up getting was what was called Wild Jujube extract derived from the fruit. However, the species used to grow Jujube fruit in China is not the same as the one used for the seed. The seed is from a wild version (Wild Jujube is Zizyphus spinosa )and has sedative effects but produces a very small inedible fruit, so they are not using the Wild jujube seed species, but the domesticated Jujube (Zizyphus jujuba) which bears much larger fruit and is not used for sleep but digestive health. This being a fruit extract is obviously not the seed from the "Wild Jujube" species as they mislead with their product name. I let them know that they had mislabeled their product, but had no response from them. Also when I ordered pomegranate fruit powder, I did not get the dried fruit powder, but instead a nasty tasting extract most likely concentrated with higher levels of ellagic acid, it was very bitter and most likely spiked with ellagic acid derived from some other cheaper botanical or left over from pomegranate peel waste extraction. They also sent me the wrong version of Yam powder, which was an extract of a totally different species. I complained about it being the wrong one (along with the pomegranate and they still sent the same wrong ones again after I sent them photo documentation of packages and a complete and thorough explanation!
While they may have some good quality extracts for a reasonable price for the vast majority of what they sell, unfortunately they do mislabel some products and seemed incapable of correcting wrong orders, besides selling the unsafe form of stevia (steviosides) which is not meant for food use, but is only to be used at very limited dosages as a supplement because it can have strong side effects compared to Stevia rebaudiosides extract which have been proven safe in human studies and food additive submissions to FDA. Maybe they do not directly recommend their Stevia as a food additive, but without labelling it with the content of actives (steviosides) and that it can have side effects and should not be added to foods and used only in limited quantities they fail to adequately represent the safety and hazards of the product since most people will assume its for sweetening purposes. Its sloppy and irresponsible business practices and they seem not to care.
