BioTRUST Sol Joy Review

This review gets into what BioTRUST Sol Joy actually offers, who it might make sense for, how it compares to other D3 + K2 supplements, and what to think about before taking it every day.

What Is Biotrust Sol Joy?

Sol Joy is a once-daily softgel supplement from BioTRUST. It’s designed to support vitamin D and K intake. Each softgel contains:

• Vitamin D3 (Cholecalciferol) – 2,000 IU (50 mcg)
• Vitamin K2 as MK-7 (from chickpeas) – 100 mcg
• Vitamin K2 as MK-4 – 100 mcg

Additional ingredients include safflower oil, MCT oil, olive oil, gelatin, glycerin, and purified water. On paper, this is a relatively focused formula. It’s built for people who need to maintain steady levels of D3 and K2 without juggling powders, droppers, or multistep routines.

 

What Makes Biotrust Sol Joy Different From Other D3/K2 Supplements?

There are thousands of D3 products on the market, and dozens of D3 + K2 blends. Most of them fall short in one of three areas:

• Missing MK-4: Many products only offer MK-7, the longer-acting form of K2, and leave out MK-4 completely.
• Low dosages: Some D3 formulas include 200–800 IU of D3, which may be on the low end for people with limited sun exposure.
• Vague sourcing: A lot of brands don’t specify the origin of their ingredients, especially when it comes to K2.

Sol Joy addresses those issues with:

• A full 2,000 IU of D3
• Both MK-4 and MK-7, clearly labeled
• MK-7 sourced from chickpeas (soy-free)

That puts it ahead of most lower-cost supplements, at least in terms of label and formulation.

Ingredient Overview

Vitamin D3 (Cholecalciferol)
At 2,000 IU, this falls within the upper end of daily maintenance for most adults, especially those who don’t get regular sunlight. It’s the same form your skin produces with sun exposure, and it’s generally considered more bioavailable than D2.

Vitamin K2 (MK-7 and MK-4)
The dual-K2 format is one of Sol Joy’s strongest features. MK-7 is the longer-acting form that stays in the body longer. MK-4 works faster but doesn’t last as long. Including both offers broader coverage than most single-form products. Also important: MK-7 is derived from chickpeas, which may matter for anyone avoiding soy.

How It Comes

Sol Joy uses a softgel with oil-based carriers: safflower oil, MCTs, and olive oil. This isn’t unusual for fat-soluble vitamins, and it generally helps with absorption. The softgel itself is made with gelatin, so it’s not vegetarian.

What Biotrust Sol Joy Gets Right

• No Unnecessary Extras: This formula keeps it simple with just three ingredients, the kind people often take together if they want to keep their supplement routine easy.
• Full-spectrum K2: Very few products include both forms of K2. And those that do usually include lower doses. Sol Joy’s use of 100 mcg of MK-4 and 100 mcg of MK-7 is uncommon and well above average in this category.
• No flavorings, sweeteners, or extras: Some D3 supplements come in gummies or flavored liquids. That may be fine for some people, but Sol Joy sticks to softgels without any added sugar, coloring, or taste agents. For those who prefer minimal formulations, that’s a plus.
• Small, easy-to-swallow capsule: Since this isn’t a powder or chewable, it doesn’t require measuring or mixing. You take one and you’re done — easy to travel with, easy to remember.

What It Doesn’t Include (And Why It Matters)

• No magnesium: Some practitioners argue that magnesium plays a role in how vitamin D is metabolized. Sol Joy doesn’t include it, so if you’re taking D3 long-term and your diet is low in magnesium, this is something you may want to address separately.
• No other vitamins or adaptogens: There’s no zinc, no B12, no ashwagandha, and no added herbal blends. It’s strictly for D and K intake.
• Not suitable for vegans or vegetarians: The softgel uses gelatin, which may be an issue for those with dietary restrictions. This is common with oil-based capsules, but it limits who this product is for.
• Includes safflower oil: While safflower oil is generally safe and commonly used in supplements, some users prefer to avoid seed oils. That said, it’s a minor component and unlikely to be a dealbreaker unless you’re strictly avoiding them.

When and How to Take it

Biotrust Sol Joy is intended to be taken once per day with food. Since vitamins D and K are both fat-soluble, taking it with a meal that includes some dietary fat can help support absorption.

Some people, based on labs or practitioner guidance, may take a higher dose. Each softgel provides 2,000 IU of D3, so doubling up would deliver 4,000 IU. Always check with a healthcare provider if you’re considering higher intake.

Where to Grab BioTRUST Sol Joy and How Much It’ll Cost You

As of now, a single bottle of Sol Joy (60 softgels) is listed on BioTRUST’s official site for $29. That breaks down to about $0.48 per day if you take one per day. They also offer bundle options that lower the cost:

• 3 bottles: $78 total ($26 each)
• 6 bottles: $132 total ($22 each)

Free U.S. shipping is included with most orders, and each purchase is backed by a 60-day refund policy.

When you compare the dual K2 formula and clean label against other D3 products, this pricing is fair. Lower-cost D3 softgels often skip K2 entirely or underdose it. If you tried to buy D3, MK-4, and MK-7 separately, you’d likely pay more.

 

Sol Joy is sold primarily through the BioTRUST website, though it may also appear on Amazon or other retailers. Buying direct gives you access to their return policy and potential bonuses (like free eBooks and shipping).

How Biotrust Sol Joy Compares to Other Options

• Dual K2 forms: Sol Joy includes both MK-4 and MK-7. That’s uncommon and helpful if you’re aiming for a broader spectrum.
• Chickpea-sourced MK-7: A plus for soy-avoidant users. Some cheaper products still use soy-based K2 without disclosing it.
• No unnecessary ingredients: There’s nothing here beyond the core actives and carrier oils. That keeps it clean and avoids possible interactions.

Quality You Can Count On:
BioTRUST is known for being transparent about its ingredient sourcing and uses third-party testing to verify purity and label accuracy. This can be important for those who prioritize quality and independent verification.

Who Might Want to Use Sol Joy

Sol Joy could be a good fit for:

• Adults who don’t get regular sun exposure
• People avoiding fermented foods or dairy
• Anyone already taking a base supplement but missing D3 or K2
• Users who prefer softgels over powders or flavored options
• People who want to know exactly what they’re getting, with nothing hidden

It’s probably not the best fit for:

• Vegans or vegetarians (due to gelatin)
• Those wanting a multinutrient formula in one pill
• Users already supplementing with high-dose D3 or K2 separately
• People who prefer gummies or flavored delivery systems
