By Twinlab20 Reviews
The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.
Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.
Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.
The Shipping Weight includes the product, protective packaging material and the actual shipping box. In addition, the Shipping Weight may be adjusted for the Dimensional Weight (e.g. length, width & height) of a package. It is important to note that certain types of products (e.g. glass containers, liquids, fragile, refrigerated or ice packed) will often require protective packaging material. As such, these products will reflect a higher Shipping Weight compared to the unprotected product.

iHerb Customer Reviews
I've recently tried/reverted to a couple of TwinLab products after trying other brands and realising TwinLab use much less filler - their caps are usually VERY small, which I like. Small caps mean less filler and that means less toxic junk. However - I found this dose simply too much in one cap, and because the caps are very small, they're too hard to pull apart in order to take less. I guess you could say this is very effective (or toxic), because I found it to cause an extremely nasty/flat/lethargic/heavy gravity feeling that rendered me unable to move/sliding down my chair/needing to stay horizontal plus nausea that didn't - start - to go away until I took some iodine and zinc to compensate and the iodine/zinc started to metabolise. It was awful - I felt like rubbish for a good few hours. Note that I take iodine every day and zinc pretty much every day, so it's unlikely I'm deficient. I've successfully been taking 50mcg of a different selenium product and this has never happened before, nor did it happen with a liquid selenate I've tried in the past. The thyroid needs selenium to convert thyroid hormone T4 to T3; selenium and zinc are antagonists (which I knew - as are selenium/magnesium) - so either this is a terrible product that simply doesn't agree with me, or I need much less selenium than 250mcg. Most frustrating - I was really looking forward to trying this because it's the same type that's been used in asthma/inflammation/circadian rhythm studies. I wish TwinLab did a 50 or 100mcg cap - I personally feel that would be ideal, because it'd mean other nutrients don't need to be increased/megadosed to compensate. I just don't understand the megadosing thing within the supplement industry - a lot is seldom better. At this point, I'm highly unlikely to take this one ever again - the reaction was that bad that I won't risk it. I'll stick to food and/or cutting a 100mcg tab in half. Suggestion - if you have a health issue that relies on iodine, zinc, magnesium or phosphorus supplementation or struggle with low levels of any of these nutrients - perhaps avoid this selenium at this dose, or open the caps and try taking less initially.

If you take selenium to help reduce your risk of cancer, you need to know that not all forms of selenium are equally effective in doing so and that sodium selenite is likely to be more effective than some other forms, including selenomethionine. Selenium has anticarcinogenic effects, which is a major reason why the mineral is taken as a supplement by so many people. A recent paper explains why, in terms of cancer prevention, selenate, selenocysteine, or selenomethionine are less preferable than selenite. The authors explain what they have discovered about how different forms of selenium can exert different cytotoxic effects against cancer cells.
