I don't trust their product example; Boluoke 150 mg, all the other good brand company are only of around 20mg per caps and 2 or 3 time more expensive. Same for the nattokinase for the same strength double woods supplement the caps is really more small in comparaison of other brand

Supplements have no effect whatsoever for us. We have purchased many hundreds of dollars of their supplements. Independent lab testing they advertise is not real. CLabs tested their saffron and said it only had 3% of the claimed amount. CL said the Double Wood brand is therefore not recommended.

I've been taking multiple of their supplements for about 8 months including NMNH, Saffron extract, TMG, Fisetin, and Quercetin. I'm happy with the quality. I looked at A LOT of reviews and I haven't found any real evidence that Doublewood's products are anything but legitimate. To people reading this, I suggest you do the research on your own as well. Research the supplements fully and the company. I've worked in neutraceuticals and you need to be sure for yourself and your own health. There are plenty of companies using low cost and or contaminated products. Doublewood doesn't appear to be one of those companies.

Happy customer from Europe, ordering Sulbutiamine.

This company does not sell good quality supplements. Symptoms of nausea and tingling arms tied directly to a new supplement I purchased from this company. They are probably sourcing their supplements from China that are either fake or very low quality.

Doublewood supplements has terrible customer support as many others have reported. Doublewood supplements is convinced I'm a criminal. I am not a criminal. All of my orders have been canceled my and they've blocked my IP address from pages on their website. I've sent them a copy of my passport. There doesn't seem to be a way to fix this with the company as they plain and simple don't care! *** And now they lie in their response.

I have been taking Benfotiamine for pain for a while. Unfortunately, Benfotiamine was unavailable from Double Wood for several months, and there is no date when it might be available. So...I ordered from a different company but it wasn't as good as Double Wood Benfotiamine. Imagine my pleasant surprise when I received my subscription order from Amazon! I am so happy to have my Double Wood Benfotiamine back.

The bottle does not state what the ratios are of this herb. I also read that the lab they claim certifies their herbs as organic or heavy metal free phone is inoperable. I have stopped taking this herb because it may have screwed up my thyroid function and I have to for testing. Check out the companies you buy from first and do not buy from Amazon. Fake reviews.

Label said 1500 mil. with per serving in small print below. A serving is 3 capsules. My bad, but it's a little misleading. I could have gotten a better deal elsewhere.

Product ordered, out for delivery but never delivered. Double Woods customer service checked, found the postal system lost it. But I was made whole 2 days later when it arrived around 9PM the day before Christmas/Hanukkah! The most effective Magnesium Glycinate delivery system marketed!
