St. John's Wort is a dark brown powder that is soluble in water and ethanol. It contains 3-7% Hyperforin, 7-12% Flavonoids and 3-5% Xanthones.


Supplementation of St. John’s Wort may cause light sensitivity, particularly to those who are fair-skinned. It is recommended to avoid direct sunlight. Some studies show that St. John’s Wort, when taken with other types of antidepressants, could cause confusion, headache, dizziness and nausea.

It might also manifest an adverse reaction when taken with certain drugs intended for HIV infection, birth control, anti-coagulation and more. Since this product might have a number of drug interactions, it is best to first consult a physician regarding use.

St. John's Wort is also believed to contain Tannic Acid, which can adversely affect the body's absorption of Iron. In this case, patients are advised to take an Iron supplement to avoid deficiency. Those with a history of liver problems should not take this product.


St. John's Wort extract is soluble in water and ethanol. The tincture preparation is slightly soluble in water but mixes well with alcohol. Alcohol is used in the preparation of tinctures due to its ability to prolong cell life and speed up the transport of the supplement through the mucous membranes and into the blood stream.

Top quality!
I have used St. John's wort for a while, as I seem to respond well to it. The effects are subtle, but I'm sure this is more potent than others I have used. The flavor is somewhat pleasant, and this is much stronger tasting than other brands I've tried. Another quality product and great value from Bulksupplements. *

I have been taking St. John's Wort capsules daily for several years now to help with my mood disorder. This is some of the most potent that I have found, so now I make my own capsules. Even better than the pharmaceuticals.*

Bag won't seal
The powder is good. It tastes natural and herbal. It's bitter, but the taste is not really noticeable when mixed in with food.

I take away a star because my bag won't seal. I think some of the powder has jammed the zipper. *

St John's Wort Powder
My husband and I have been taking the 1/2 teaspoon for about a week. It has minimal taste to me and since he hasn't complained, it must not taste bad to him either. It helps with alertness and calming. I will reorder. Thanks. *

Already lifting the blues away!
I couldn't wait to get this St. John's Wort. I used to take capsules about 3 years ago but stopped. Lately I have noticed how it was getting harder and harder to even want to get out of bed to get the day started and that I felt more gloomy so I decided to give St. John's Wort a try again. I decided to purchase the powder from Bulk Supplements because of their great reviews. I received the St. John's Wort early Thursday afternoon and took a dose right away. Friday morning I was up and out of bed at 5:00 a.m. Something I haven't done in months. Same since, up at around 5 and ready for the day. I am grateful to Bulk Supplements for the high quality of their products. This is an awesome company and so far the St. John's Wort seems to be working. I am very pleased!!!*

Very good product
And I have no other reason saying so than the truth. This Saint Johns Wort is no exception. Since the flowers of this plant are yellow I was expecting the powder to be yellow, but it is actually brown. It smells kind of like chocolate. The taste isn't as bad as I thought it was going to be and it dissolves ok. I find with the BulkSupplements powders (that I don't make into tinctures) that it is best to let sit in a glass of water for a few minutes and when you add the powder to the water try not to let it all into the water at once in one glob, but gently sprinkle it around which prevents it from clumping. The effect is quite nice and makes one mellow. I have one concern with this product, however, and that is the possibility of serotonin syndrome. I take a lot of Gaba, 5HTP, Theanine, Tryptophan, and others (all from BulkSupplements) and I don't want to overdo it with this product so I am going to take sparingly. What finally got me to buy it and get through my reservations was the antibacterial and antiviral properties the herb has that I hitherto was unaware of. I don't know yet if the herb is part of my all-star lineup or not yet. It will have to depend on how mellow I get and also if I experience any side effects of serotonin syndrome. *

clean and effective
this is a good quality powdered from of SJW, small doses seem to elicit equal or stronger effect for me than pre-made formulations so a little can go a long way. *

Quality product
I have been taking this St John's Wart for a week now. I started off taking the full dose, recommended on the package and found that it made me feel lightheaded. I ended up dividing the full dose and taking it in the morning and evening instead. This stuff really works! It has a calming sort of effect for me. I would recommend filling gel capsules with this extract due to it's taste. *

Going on 3 weeks now and Very Satisfied!
After having a brain aneurysm and stroke, I have been taking Celexa for the past ten years. After much reading and investigation, I decided to stop taking the Celexa "cold turkey". I've replaced the Celexa with pure St. Johns Wort and I am happy (no pun intended). I feel absolutely great taking a half teaspoon per day mixed in my cold green tea. :)*

This is a good quality extract
I found this to be a bit more potent than the pills at the pharmacy. 750mg of this powder helps to keep me more motivated at work and more patient with the kids. Thanks! *
