I’ve been using this supplement for a few weeks now, and I can honestly say it works. I was a bit skeptical at first—as you always are with supplements—but I’ve noticed real, consistent improvements since I started taking it. Whether it’s increased energy, better focus, or overall well-being (depending on what it's meant for), this has become a solid part of my daily routine.The quality is top-notch. The capsules are easy to swallow, there’s no weird aftertaste, and the ingredients list is clean—no unnecessary fillers or junk. I appreciate that it’s clearly labeled and professionally packaged, which gives me confidence that I'm putting something reliable into my body.Shipping was fast, and it arrived sealed and fresh. I’ve tried other brands in the past, but this one stands out for both effectiveness and quality. I’ll definitely be ordering again!Highly recommend if you're looking for a supplement that actually delivers results.

Powder mixes well and relatively tasteless. Vitamin D3 is a powerhouse in immune system health.

I love the powder form, it is easy to swallow! There are not a lot of added ingredients. I add my powder to apple sauce or smoothies.

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.

Went from 26 on my blood test to 50 to now 150, over the course of 9 months while adjusting the dosage up and up and up. Yup, it works. Now I am technically on the "Toxic" / overdose side of the scale but don't have any issues. I highly recommend This product. Just make sure to also get a good cheap scale and measure out what the daily dose is and multiply it as needed. and of course, get blood work done every 4 months or so to see where you are. Technically speaking, I believe this is something you could theoretically calculate before hand and fix your deficiency with a single dose. But experimenting with low dosages lets you find what exactly is it that you need the daily dose to be for your given life style.I am Happy. and my neck no longer hurts (it stop hurting within like 2 months of taking this). and yes, I am taking a break from this product for a bit until my levels come below 100. Then I will start up again. I was doing something like 12-16 x the amount found in AG1's daily D3 drop dose the last 3 or 4 months. I would forget to take it some days though.

great product

You'll need to have mg dosing spoons or a mg food scale at home to measure out a 50mg dose (no approximate tsp equivalent offered).This product contains maltodextrin. It isn't clear what percentage of the product is maltodextrin, but it's in there. It's not a problem for most folks, but it may be for some.So I'm ordering the equipment I'll need to measure the product. I'm hopeful because the company's products are generally good.
