Kirkland Signature Extra Strength D3 50 mcg, 600 Softgels

Easy to swallow for its size. Great price for 2 bottles. Vitamins arrived in good condition no melting inside.

Why did you pick this product vs others?: U Effectiveness: Sed this for years

I increased my intake from 4,000 to 6,000 IU about 5-1/2 months ago after finding a rule of thumb that the body needs 2,000 IU per 50 pounds of body weight. I weigh 170. Per last week's blood work my vitamin D serum level (25-hydroxy) is 97.7 mg/dl which is at the high end of the normal range. I take it with meals along with 300 mcg daily of vitamin K2 to keep calcium in teeth and bones where it belongs. This product is like sunshine in a bottle. Small, easily swallowed, no aftertaste, and big results for not much money.

buen precio para la cantidad

They're easy to swallow and seem to work great. The price is the greatest part. Highly recommend.

Pharmacist here. Supplements like this aren't regulated by the FDA, but by DSHEA. So if you're not buying brands that opt for independent third party testing then the lower price you're paying may be explains by them using just less of the actual ingredient than the label says. Kirkland typically uses USP which is the peak of respectability of lab verification. The only other reliable brand I buy (without researching them) are ones like Nature Made, or certain niche manufacturers for less common products. Surprisingly many post-hoc studies have found that even national store brands have had zero of the labeled active ingredient in their products on store shelves. But obviously pharmacists are motivated to not disseminate this info as it's made by essentially their employer. In conclusion, the law is crud but there are workarounds for the motivated consumer. Tirade over.

Extra good value.

have been using this product for years and am very satisfied.

These are very small softgels, smaller than my previous 1000 IU from another brand.
