Some research suggests that 75% of the population are not getting enough sun exposure.

With even a mild vitamin D deficiency having a significant impact on your immunity, vitamin D supplements have increasingly become one of the most recommended products to take.

If you’re like me, then getting out in the sunshine during the day is a bit difficult when you’re trying to juggle work and life.

Unfortunately, there are many low-quality supplements out there.

And before you just try to boost your vitamin D intake with the first product you see, let me show you what our research has found.

Our Top Vitamin D Supplements

Buyer’s Guide

How Much Vitamin D Should You Take?

Most supplements will usually provide a dose of D3 that is close to the 125mcg recommended by medical scientists [2]. But it’s sometimes necessary to get a higher or lower dose per day.

The first thing you should do when comparing products is to look at the dosage to accurately compare the prices.

If you have particularly low vitamin D levels, or you have been recommended a precise dosage, then it might be best to use a product with a high dose or one in liquid form that makes it easier to measure out an exact volume.

What’s The Difference Between Vitamin D And Vitamin D3?

Vitamin D3 is the closest related to the vitamin D the body produces, and it’s a bit difficult to get from food sources [3]. The recommended form of vitamin D in the medical industry is pretty much always D3.

And the lack of sun exposure and common use of sunscreen may lead to a vitamin D deficiency.

“Vitamin D is known as the “sunshine vitamin” because it’s produced within the body when the sun hits the skin. But many people turn to supplements in chillier months of the year when cold and dark days limit time spent outdoors.”


- Sheryl Huggins Salomon, Health and wellbeing journalist


Other forms like D2 have been tested as well, but the research results have been a bit mixed. That’s why we focused our attention on providing product suggestions that provide only D3.

About the author

  • I’ve tried your #1 and #3 recommendation and I liked PhenQ more because I lost more weight. These pills are definitely the best thermogenic fat burner for men (not sure for the ladies tho)

  • I immediately purchased one of the products highlighted by Isaac. Since then, I have been taking for a week now. I never usually take any of this kind of pills for anything, but I wanted to shed a few pounds that I have gained over this quarantine period which has been hard to get off and it is pissing me off. I’m taking two pills twice a day. I don’t know if it’s just me, but I do feel and notice an immediate boost in energy and a little parched. So, make sure you stay hydrated with this when taking this. Also I ride my bike at least 3 times a week and it would take me about 45 min in before I start sweating before I started using this. Now with the pills, I am totally drenched in sweat 15 min into my activity. So evidently something extra must have been working on with me. I don’t know if this is the pill or not, but I find myself eating less and not snacking as much. I can’t even finish 1 plate of food anymore. My body does feel like it is changing, and I can already see a little difference from now even after just a couple of weeks. I will keep taking and hope for the best. Overall, I am glad I listened to Isaac about his thoughts. Please do listen to him as well.

  • Before I will start, I would like to extend my gratitude for the effort Isaac has been putting to help us with our decisions. Thank you, man. Now, let me tell you what I have experienced. Actually, this product is pretty amazing!!! A big disclaimer is if you put in the work. As I have noticed, it decreases my appetite so I’ve found that I only eat about half portions at meal times. I eat kind of healthy to begin with but I do not stick to a strict or specific diet as some of you may have been doing. I purchased this not a few while back and started using it immediately after preparing my needs. It gave me energy to do extensive physical activities, and even just do simple household tasks which we all men avoid to do. When I started, I initially weighed in around 160 pounds. I had previously been prescribed with another product by a friend but I was looking for something that fits my budget. I wanted to lose 10 more pounds and figured I could do so with a bottle of this. Just this morning, I weighed myself and I am 150.2. To be honest, I don’t work out every day since I am busy with work, but this has really controlled my appetite which has always been my biggest issue. So my advice is for people out there is listen to what Isaac say. He truly knows what he is sharing and people must try it! It’s at a great value to try it out because it really helped me deal with losing that last stubborn few pounds. Thankful for Isaac. Let’s keep on losing those unwanted pounds!

  • One of these product works and I’m glad I stumbled upon your post before actually purchasing one! But, it would be unfair for the product if it works and you are no doing your part. So you also have to do your part. What I am trying to say is this. I’m a huge snacker every afternoon. So at noontime I take 2 pills. It holds me over til dinner. Simple as that! I’m up before the sun rises every day. I have would take the usual breakfast. Before lunchtime, I have to eat a nice size lunch. Then by noontime, I pop 2 of these pills and these pills will take me until the sun sets. When the night comes, I eat dinner. Done and that’s my usual routine. What may have worked for me may not necessarily work for you. So you have to figure out for yourselves the right time to take these pills and you’ll see results! Thanks Sir Robertson. I am a huge fan of yours.

  • At first I was unsure about this product but when I started doing my research, I ended up in Isaac’s post. I have been trusting him for my decisions when it comes to this thing. I got encouraged to order some right away and believe it or not, that was the last money I had left on my debit card. But I wanted to try this product so much that I said why not plus the words came from your trusted writer Isaac who had a lot to do with me making up my mind whether I was going to try this product or not. When I finally ordered it, I couldn’t wait to get it. When I received it, I started using it immediately and I started seeing results immediately. I am a part of a gym so I’m working out as well. the stubborn pounds are just melting off like sweat. It’s like someone put it in a pot and it just melted away like magic. I am glad I listened. Thanks Isaac.

  • I’ve just started using this product when I found out that Sir Isaac has done and posted his thoughts on these. As soon as I began, I have noticed a significant reduction in my appetite. I’m usually someone who has constant cravings that are uncontrollable – not just simple hunger, but that pregnancy-strength cravings similar to what my wife has experienced when she was pregnant. Those cravings that can only be satisfied with whichever specific food. With this product, I’ve found that I’m much more in control of what I actually put in my mouth, not just how much, and it’s really helped me stick to my goals. I also have really appreciated the professionalism of Isaac in the way he conveys his thoughts. It’s clear that he genuinely cares about his avid readers’ experience. 10/10 will purchase again when I am out of stock. Thanks!

  • I have always been skeptical of these kinds of products. I have researched so much throughout the years on many brands and products. I finally decided to give this brand and formula a shot since Isaac has been my trusted writer over the years. When I tried it, actually it works. I started out with one pill as recommended for about a week, then been doing 2 since then. I’ve lost about 10 pounds, and I’m still using the product now as of writing. I would recommend these if you’re looking for a true pill that works like magic. I wasn’t sure if it would work, but it does, and I’m glad I bought them. Thanks for encouraging me Isaac. I am a more invested reader starting now.

  • First of all, thank you Isaac for the thorough list. I tried this because the I have been his reader since who knows when. Also I’m the father of the bride in 3 weeks with a hundred things to prepare for and lots of pictures to pose for soon. This product is amazing. I’m only on day 2 and will keep you guys posted in a month if I remember to write it. Day 1 was unreal. I had no idea I could feel so alert, able to make quicker decisions that have been hard planning a wedding. My house hasn’t been this clean in a while and I had energy all day to clean it. My mood was better than it’s been in a long time. While I’m certainly not an expert in this area, I’m so glad to feel the benefits of this on day 1 taking one pill twice a day. I can feel the appetite suppressant working however I’m more happy about the mood boost and energy at this time. If your hesitant to try a product like this, I can say this is worth a try for everything it says! Plus Isaac has written it out so there is nothing to worry really. I’m looking forward to seeing more results after a month on this product.

  • I have seen several negative posts about these products however I did not believe them knowing that Isaac is my most trusted writer when it comes to this topic. After buying it, I immediately took it up. It works fine to me and lost 15 pounds already in a month. Of course, you also have to do your part. Try not to eat anything that’s white like bread, rice, and flour. Also drink greens such as blend, shake or smoothies whichever works for you. For dinner, I eat salad. Most important is that you eat right. If you are full then don’t eat until your tummy tells you to eat something. Take a pill when you wake up, drink greens for lunch then have healthy meal for dinner. You cannot just take a pill and not doing anything or eat all you want to. This WILL NOT help you lose weight!!!

  • I don’t normally use products or dietary pills but when weight keeps you from doing what you want you’ll find any means to change that. Initially, I started using this product to help my metabolism in conjunction with going to the gym and only a few weeks after I started I’ve already lost 8 pounds. If this product didn’t work for me then I wouldn’t leave a comment like this. But it does. So if you’re considering a product that will help you shed off those pounds, this is what I would consider a tried and true product you should consider purchasing. Thank you Isaac. I am new to your blog but I am glad I listened to your loyal readers.

  • Will try this product and leave a review in 1 month. I tend to gain and lose fat very fast so this should be interesting.
