BulkSupplements.com Vitamin D3 Powder - Cholecalciferol, Vitamin D Supplements, Vitamin D3 5000 IU - Gluten Free, 50mg (125mcg of Vitamin D3) per Serving, 5kg (11 lbs) (Pack of 5)

This helped my mom get her D levels back to normal. I give her 10,000 UI with 200 mcg k2 every day.

I bought the 250 g (8.82 oz) size and a "smart weigh GEM20 digital jewelry scale" to weigh out the tiny amount needed for a dose. The package gives a serving size of 46 milligrams (easy to weigh on my newly calibrated scale). 46 mg equals 5000 IU, which is more than my doctor recommended, so I cut it in half to 23 mg per serving, and have it once a day. The servings per 250 g? For 5000 IU, that would be 5434 servings. Double that for 2500 IU. At $24, this comes out to approximately 2/10s of a penny per serving. :-) If it wouldn't eventually degrade, I wouldn't have to buy more for nearly 15 years, given that both I and my daughter are taking it. I am sharing it with friends, so that it all gets used. :-)Beyond the price, which I really, really appreciate, I like this because it doesn't have "fillers." My daughter is always manifesting new food allergies and intolerances, the latest of which is to stearic acid and magnesium stearate. When you realize what a tiny amount of powder constitutes 2500 IU, you will see that the capsules are mostly filler. Now my daughter can safely take Vitamin D3 again.The package does warn "Potentially toxic in higher quantities." If you do not have a scale capable of accurately measuring .001 g, you will need to buy one in order to safely use this product.In addition, it is important to balance vitamin D with Vitamin A: food sources are best for A, so some liver or salmon once or twice a week.

I have always preferred non oily Vitamin D. I was taking a very expensive brand that helps me with eczema. When I realized my horses skin issues were probably a form of eczema caused by an allergy to the saliva in bug bites I researched dosage and put him on it to. My horse is very large and could use 4 times the my dose. I bought this product for him a year ago and when I ran out of the other I switched to it as well. My eczema has remained in remission during it's use which tells me the product is as advertised. My horses skin issues cleared up last summer and remain stable.(pun haha). I read a review that said 46 mg's was the wrong dosage. WRONG, it's exactly right. I read one review that says it's not pure, well Shame on Bulk Supplements for that because the package say's pure and yet it does contain fillers though any non oily capsule will contain fillers as well. Then I read a review that complains that it is to hard to measure, that is true except I keep a scientific scale around so my wife can measure components for cosmetic she compounds so I could weigh it accurately. I use a scientific spoon set I bought here on Amazon to dip it out of the package https://www.amazon.com/Scientific-Labwares-Stainless-Laboratory-Measuring/dp/B0881YF2KL/ref=sr_1_9?dchild=1&keywords=small+chemistry+spoon&qid=1621899100&sr=8-9and after about 100 times I determined that one level spoonful was 50 mg so it's easy to measure and if it weren't for the fillers bulking it up a little the size of a dose would be so small it would be hard to measure.On a side note I am in my 60's and have had a winter cold every year all my life, 2020/2021 winter was the first time ever that I took (this) Vitamin D all year and I had no cold. BAM 5 Stars

Nice, packaged well, lots of Vitamin D3

I liked swift delivery; parcel was especiallysuitable .A 50mgm suitable teaspoon would be good idea.

Pure vitamin D makes a good rat poison, but taken by humans in the doses listed here causes hypervitaminosis D and hypercalcemia with deposit of calcium in soft tissues including arteries. Death by heart attack or stroke often follows blood vessel calcification. If this product is actually pure vitamin D, as they have claimed, then the doses they list are deadly excess.On the seller's own site, they claim it is the rat poison concentration. Here's their quote"Serving Size & Timing"Because of how concentrated this supplement is, it is not safe for general consumption. Unless you are a pharmacist or other kind of medical professional, you should purchase the Vitamin D3 capsules that are fit for public consumption. If you do choose to use this supplement in powdered form, it should be consumed in servings of 10 to 50mg per day, and because the sizes are so small it is best to use an accurate milligram scale to apportion out the correct serving sizes."It is recommended by the FDA that D3 be taken in servings of 4000 IU per day. As a serving of 37mg will deliver 100% of that daily value, it is best to measure this supplement out with a milligram scale so no overdosing occurs. Vitamin D3 is highly toxic in higher amounts. Vitamin D3 supplements with concentrations at this level should never be measured out with measuring spoons, only with scales; as the amount at which overdose occurs is so miniscule."If that's true, vitamin D poisoning is the fate of many or most purchasers, especially if they follow the "take a teaspoon" instructions the seller lists elsewhere.If the teaspoon doses the seller lists are the part that is not false, then the product is not at all pure, but is only a tiny bit of vitamin D cut with some excipient they haven't listed, so you are buying and taking only a small fraction of vitamin D and a large dose of unknown white powder. The white powder is an adulterant, identity concealed. And with so little D, not an especially good buy, even aside from the risk. Adulterant sold at the price of vitamin D.For your health, why would you take something with ingredient information online and on the package so garbled and contradictory you can't tell if you are getting so little there is no benefit or so much as to cause you permanent damage? Whether it's actually your health you are trying to protect, or just your pocketbook, you can find products labeled with honesty and care, especially products with a narrow dosage window like vitamin D where accuracy in labeling can be life or death. If they were concerned about the truth, they would determine which information is false, and correct it.This company sells other bulk vitamin products on which it openly lists its adulterants as it should, giving consumers information needed to gauge dosage, price, and safety. For vitamin D, this basic duty to consumers is ignored.The seller gives out flat contradictions about rat-poison-pure vs. hidden adulterant on its Amazon description vs. its Amazon picture of package vs. seller's own web site vs. seller's actual package when it comes. If you guess wrong which is false, you harm your health or get ripped off.It would almost be funny, if it wasn't dangerous, that the product photo as displayed by the company today on Amazon today actually lists in the fine print that it is Creatine.Since the irresponsible labeling is either fraudulent or dangerous , the rating is zero. Or as close as I can get.

Tastes like milk powder.
