Rated 5 out of 5 by from Good Value on a Great Product I like taking this supplement. It seems to work for me. I used to get it at GNC, but the Puritans Pride version is a much better value.

Rated 2 out of 5 by from THE TABLET ..... The tablet is way too large !!!!!! I can't get it down my throat and would be that most if not all would have trouble also !!!! Perhaps a gel tab or a capsule would be better?

Rated 3 out of 5 by from Better, before the change of coating. These pills used to be perfect before the removed the chalky coating off the exterior. They might go down easier, but they are not as effective.

Rated 3 out of 5 by from Too large to swallow The product may work well but it is so big and chalky that it is too hard to swallow,. It looks like a horse pill. Maybe if it were a gel cap it would be easier, going to shop around, maybe taking 2 of the 500 would be better. Puritan Pride always delivers on time and has fast shipping, this product just wont be something I will purchase again due to its size.

Rated 1 out of 5 by from Disappointed After using this product, and actually taking 3 a day - my husband's blood pressure has not decreased a bit and in fact seems to be going up a little. His sugar's have not been helped. Very disappointed in this product.

Rated 5 out of 5 by from The best comment I can make on this product is that it works. I have been using this particular product for almost 3 years. It meets my needs and has been very effective in providing me with an energy boost in my daily routines. I have been able to have more endurance in strenuous physical exertion. The best part is that the tablets are easy to swallow and they seem to breakdown very quickly. You feel the effect of their presence in you body relatively quickly.

Rated 5 out of 5 by from Big Bang for Your Buck I am very satisfied with the service and rapid delivery of the product. I have been taking the supplement for about two weeks now and have noticed some difference in my energy level--but I'm waiting to see what the future brings since it's still early in the evaluation process.

Rated 5 out of 5 by from Best Product I found I was looking for a product to give me back my energy and help with my exercises. I did not expect it to work this well, it was gradual. At first I did not think it was working but then I noticed I lasted a little longer and as I used it I noticed more and more increased ability. This stuff is great.

Rated 5 out of 5 by from Works great, dissolves very quickly I take 5 of these (1000 milligrams each) per day. They dissolve easily (try putting one in a glass of water and watch. just 10 mins. Lots of pills and capsules, big or little are much harder to digest.) The problem of size is easily solved. Either cut them in half (pill cutters work quickly) or take them with a heavy liquid, like tomato juice or protein drink. It make big pills, caplets or capsules go down easily. I take nearly 50 supplements a day; the heavy liquid allows me to take 6 to 10 at a time (depending on size) easily.

Rated 3 out of 5 by from Pill is too wide to swallow Product is fine but too big to swallow. I'm used to swallowing large pills but this one is too wide it gets caught in my throat
