Dr. Mercola's Nanotechnology Vitamin D-3 Spray 4.3 5 24 28
LOVE IT !! LOVE DR. MERCOLA LOVE THIS SUPER EASY CONVIENENT WAY TO GET A DOSE OF VITAMIN D. TASTES GOOD TOO. May 25, 2012
LOVE THE SPRAY--BUT NOT THE BOTTLE This is an easy and effective way to get your daily dose of Vitamin D (love the B spray too by Mercola). However, I've had problems with the bottles clogging up. Swanson has been willing to send a new one each time, but the new ones clog up too. Any suggestions? This item is great, but needs new packaging--go back to the old packaging where you could open the bottle-thus rated satisfaction lower. April 17, 2012
Dr. Mercola's Vitamin D-3 Spray I have been using this Vitamin D-3 spray for about 8 months now. When I had my annual physical this year in January, my Vitamin D level had gone up to 67. This supprised my doctor, expecially since I had not much sun exposure, and he rarely sees this level of Vitamin D. I am 80, so I don't run around in a bathing suit or shorts any more. I have been reading about how important it is to have a minimum of 50, so I am very happy with the results. April 11, 2012
spray doesn't work This is a good idea to spray in your vit D, but in the bottle I got, anyway, the spray mechanism only works sporadically.....mostly it doesn't deliver a spray. I'm going back to vit D in olive oil. April 7, 2012
I love how convenient the size of the bottle is. I can take it with me every where I go. March 29, 2012
Vitiam D Spray I love the spray it is easy to take and tastes great. If you like spearmint that is March 28, 2012
good product Seems to be effective but must have d3 level checked again to know for sure. If nozzle stops up. take a pin and clean the orfice March 26, 2012
Love this Take this product with an Omega 3 food source. Found product really works: skin is better, immunity seems to be up. Found new bottles work better if you shake it before spraying. March 11, 2012
swansons vitamin 3 d3 i been using this for years now but all of a sudden my bottles are clogged and since you can not open the bottle i tried everything normally you would take the top off and clean it but there is no way if someone could help .. but i am m sorry i do not recommend this February 21, 2012
Good Stuff Tastes minty. I have not had the trouble that other experienced with it jamming up. Very convenient to get your Vitamin D using this. I have not gotten a blood test to see what my vitamin D levels are, but I feel good, so I suppose it's working. December 29, 2011
Vit D spray I liked the old spray bottle better. This one does not work properly and gets clogged repeatedly. December 8, 2011
Sprayer Doesn't Work This was a great product until the sprayer was changed a year or so ago. Now 4 times out of 5, we are throwing away nearly full bottles. A waste of money. Why was the sprayer changed?? November 27, 2011
Not with the new packaging I loved this product until they came up with the "new and improved" packaging. It was a solution in search of a problem. Now, the spray gives out and the system clogs up leaving most of the spray still in the tube. I, too, will go back to it once it is returned to it's original package. November 13, 2011
Terrible new spray top I used to use this product every morning. That is until this morning when I realized that I had to throw out the third bottle in a row that was 3/4s full due to the faulty new spray mechanism they switched to. The old sprayer worked perfectly, when you bring it back I will be happy to order again. September 8, 2011
Very convenient and good quality Love this product because it's not another supplement that has to be swallowed. And it's convenient to use with whatever amount you need to use on a daily basis. April 10, 2011
very convenient Great tasting...Easy to use product ..take it with you...Every woman needs vitamin D February 22, 2011
Spray D# Vitamin This is amazing stuff. I use one squirt under the tongue mornings and another most evenings (when I haven't been in the sun all day). Its a quick pick up - feel good. I would like to see more supplements of the direct absorption type rather than GI track accessing. October 20, 2010
Best way for me to get this important viatmin I was very excited to find this vitamin in a spray form, which works the best for me, as it is easy to carry, being a small, purse or pocket friendly item. It is extremely easy to use, needing no water or food with it, and the after-taste is fresh and minty. I feel that it is very effective in this form, having a nano delivery system, which I believe allows it to be highly absorbable (my preferred kind of method). October 6, 2010
LOVE IT! I love this stuff! I have proof that it is effective and easily absorbed! I can see and feel the results. August 25, 2010
Top Quality Product - Best Price This Swanson product based on Mercola's nanotechnology is excellent - easy to use, high quality product, best price available. July 11, 2010
GOOD PRICE, good flavor as to the effectiveness, I have no idea, but this is definitely a better price than the competitor...and it tastes great! July 7, 2010
One less pill to swallow! Love this alternative to pill/talbet form. Nice to just squirt. Have to wait 20 seconds before swallowing but by the time I collect the rest of my supplements the 20 seconds have passed! May 17, 2010
Convenient This is the best delivery system for vitamins D-3 in my opinion. Two sprays under the tongue per day. It delivers 1,000 IU's per spray. I don't digest capsules so I'm very happy to have this product. I have read on Dr. Mercola's website how essential this vitamin is for optimal health and that higher doses are requirred - more than what was previously recommended. This product has a pleasant taste. April 15, 2010
Easy to Take! two sprays under the tongue is so much easier to take than swallowing a pill! It tastes good, which is also important to know! November 12, 2009
