Module 14: Vitamin D3 & D3+K2

When Vitamin D Doesn't Work — And How Barlean's Solves It

In Training 13, we covered our Super Seeds line and the foundational plant nutrition they deliver every day. Now we're turning to one of the most talked-about nutrients in wellness — and one of the most quietly misunderstood.

Vitamin D. Most of your customers are taking it. Many of them aren't absorbing it effectively. And the reason almost no one tells them about comes down to a simple piece of nutrition science that Barlean's built an entire formula to solve.

The Absorption Problem Most People Never Hear About

Here's the piece of the vitamin D puzzle that most people miss entirely: vitamin D is a fat-soluble vitamin. According to the NIH Office of Dietary Supplements, because vitamin D is fat-soluble, its absorption depends on the gut's ability to absorb dietary fat.

That means when someone takes a standard vitamin D capsule on an empty stomach — which is exactly what most people do, because they take it with morning coffee or forget about the food requirement altogether — they're not setting themselves up for optimal absorption. Research published in the Journal of the Academy of Nutrition and Dietetics found that vitamin D3 absorption was 32% higher when taken with a fat-containing meal compared to a fat-free meal. Most supplement users have no idea this is happening.

This is the hidden story behind a lot of disappointing vitamin D experiences. It's not that the product isn't working. It's that a fat-soluble vitamin needs fat to do its job — and most people never coordinate the two.

Vitamin D plays important roles in supporting immune system function, bone health, mood, energy, and overall daily wellness. Getting consistent, reliable absorption is what makes the difference between a supplement that sits in the cabinet and one that actually supports your health goals.*

The Emulsification Advantage — No Meal Required

Barlean's Seriously Delicious Vitamin D products are emulsified — and that changes everything.

Emulsification means the vitamin D is already suspended in microscopic droplets alongside beneficial fats. The fat your body needs to absorb vitamin D is built right into the formula, before you ever open the bottle. So when a customer takes Barlean's vitamin D, their body has exactly what it needs for faster, more efficient absorption — regardless of what they've eaten or when they take it.

No coordinating with meals. No worrying about timing. No second-guessing. Take it first thing in the morning, after a workout, before bed — it works whenever it fits into their day. This is precisely what Barlean's means by "no food needed" on the label.

This is also why people who've had their gallbladder removed, or who experience digestive sensitivity with traditional fat-soluble supplements, often find emulsified formulas much easier to handle. The fat is already incorporated. The digestive work is done before the product reaches their mouth.

When a customer says "I've been taking vitamin D for months and I don't feel a difference," the emulsification conversation is often the most useful place to start.

Seriously Delicious Vitamin D3 Strawberry Milkshake

This is Barlean's foundational vitamin D formula — and a product that consistently earns repeat purchases once customers discover it.

Each one-teaspoon serving provides 5,000 IU (125 mcg) of vitamin D3 as cholecalciferol. Cholecalciferol is the same form the body naturally produces when skin is exposed to sunlight, and it is the preferred form of D3 in supplementation. The formula is emulsified with high oleic sunflower oil for efficient absorption, naturally sweetened with xylitol, and contains no artificial flavors, colors, or sweeteners. It is gluten-free, dairy-free, non-GMO, and kosher. One teaspoon daily, ages four and up.

Many health practitioners suggest 5,000 IU as a meaningful serving size for adults with limited sun exposure, and it's a serving size that supports those who need more consistent daily vitamin D support. As with any supplement, encourage customers to talk with their healthcare provider about what's right for them individually.

And then there's the experience of actually taking it — because this genuinely tastes like a strawberry milkshake. Smooth, creamy, no fishy aftertaste, no chalky residue. Kids ask for it. Adults look forward to it. And that matters enormously when it comes to the most important factor in supplementation: consistency. A supplement people love taking every single day will always outperform one sitting untouched in a cabinet. This is how taste and results actually connect.

Who Needs the D3 Strawberry Milkshake

This product is one of the most broadly applicable recommendations in the supplement section — which makes it easy to sell and easy to love.

It's an excellent fit for anyone seeking foundational vitamin D support, people in northern climates or with limited daily sun exposure, those who spend most of their time indoors, immune support seekers especially in fall and winter, mood and energy support seekers, families who want one product that works for everyone including young children, and adults who struggle with capsules or simply prefer a liquid.

The easiest conversation of all is with the customer who says, "I can never remember to take my vitamin D with food." That is exactly the problem this product solves — and it's a conversation that closes itself.

One important note for the shelf: customers who are on blood-thinning medications like warfarin or Coumadin should always choose the D3 Strawberry Milkshake over the D3+K2. Vitamin K can interfere with how blood-thinning medications work, so for those customers, the standalone D3 is always the right recommendation. Taking this seriously is what makes you a trustworthy resource — not just a product recommender.

Seriously Delicious Vitamin D3+K2 Pink Lemonade — The Dynamic Duo

Now for the formula that takes vitamin D support to a more comprehensive level.

To understand why D3 and K2 belong together, you need to understand one thing about calcium: getting more of it into the body is only half the conversation. The other half is where it ends up.

Vitamin D3 helps the body absorb calcium. That's essential — calcium is foundational for bones, teeth, and countless cellular processes.* But when calcium absorption increases, a natural question follows: where does all that calcium go?

That's exactly where vitamin K2 comes in. Research supports K2's role in supporting calcium utilization — helping direct calcium toward bones and teeth, where you want it, and supporting cardiovascular wellness in the process.* Think of D3 and K2 as a team: D3 opens the door for calcium, and K2 helps direct it where it belongs.

Together, they support what Barlean's labels accurately as "bone health and optimal calcium utilization."* That's not marketing language — it's the science behind why these two nutrients make a more complete formula when taken together.

The MenaQ7 Difference

Not all vitamin K2 is the same — and the specific form in this formula is worth knowing.

Barlean's Vitamin D3+K2 Pink Lemonade contains 90 mcg of vitamin K2 as MK-7, specifically the patented MenaQ7 form. MK-7 is a highly bioavailable form of vitamin K2, meaning it's readily utilized by the body. It also has a longer half-life than MK-4 (the other common K2 form), meaning it remains active in the body for a longer period. MenaQ7 is a widely researched, clinically studied form of K2 — it's the form researchers have used extensively in published studies on bone and cardiovascular wellness.*

Like the standalone D3, this formula is fully emulsified — no meal required, consistent absorption, anytime convenience. Pink Lemonade flavor. Creamy, refreshing, genuinely delicious. Ages four and up.

Who Needs the D3+K2 Pink Lemonade

This formula is for customers who are thinking proactively about comprehensive bone and cardiovascular wellness — and who want their vitamin D to do more.

Anyone over 50 is a strong candidate. Bone health becomes a more active wellness priority with age, and this formula supports it from multiple nutritional directions. Postmenopausal women especially benefit from more complete bone support. Customers already taking calcium supplements are excellent candidates — the K2 in this formula supports where that calcium goes in the body.* People with a family history of bone health concerns, those interested in cardiovascular wellness, and health-forward customers who want the most complete vitamin D option available all belong in this conversation.

There's also a natural upgrade conversation with customers who already buy the standalone D3. Many of them — especially those over 50 — haven't yet thought about the calcium-direction piece of bone health, and the D3+K2 is a meaningful step forward.

The critical caution stands here too: anyone on blood thinners should not take a product containing vitamin K without first consulting their healthcare provider. Mention this clearly every single time — it's a safety conversation that protects your customers and your credibility.

Choosing the Right Product

The decision comes down to two simple factors: their health goals and their medication situation.

• Choose D3 Strawberry Milkshake for customers who want foundational vitamin D support, those new to supplementation, anyone focused on immune or mood support, families looking for an all-ages liquid, and everyone on blood-thinning medications.
• Choose D3+K2 Pink Lemonade for customers thinking about comprehensive bone health, those over 50, postmenopausal women, anyone taking calcium supplements, and health-conscious customers who want the full D3 and K2 partnership.

Both products provide 5,000 IU of D3. Both are emulsified. Both are appropriate for the whole family ages four and up. The K2 is the differentiator — and the right call depends entirely on who's standing in front of you.

Usage and Best Practices

One teaspoon daily for both products. Ages four and up.

Straight from the spoon is the most popular way to enjoy these — and once customers taste them, it usually becomes their preferred method. Both can also be mixed into yogurt, stirred into oatmeal, or blended into smoothies. No meal required — that's the whole point.

Shake well before serving. Refrigerate after opening. Both products are shelf-stable before opening. Taking it at the same time each day builds a simple daily routine — and routine is what delivers real, lasting results.

Both products are gluten-free, dairy-free, non-GMO, and kosher.

Handling Common Customer Questions

• "Isn't 5,000 IU too much?" Many health practitioners suggest 5,000 IU as a meaningful serving size for adults with limited sun exposure. Encourage customers to talk with their healthcare provider about what's right for their individual needs — and a simple vitamin D blood test can give them a clear baseline to work from.
• "Can I take D3+K2 if I'm on blood thinners?" Recommend the D3 Strawberry Milkshake instead, and encourage a conversation with their healthcare provider before adding any vitamin K to their routine. This is a safety recommendation, not a sales conversation.
• "Why is this better than a pill?" Two reasons that actually matter: first, it's emulsified so absorption doesn't depend on meal timing — you get it when you take it, not just when the stars align with your lunch. Second, it tastes genuinely delicious, which means people actually take it consistently. Consistency is what drives results.
• "Do I really need vitamin D?" Getting enough vitamin D from food alone is difficult, and many people in northern climates or with indoor lifestyles aren't getting adequate sun exposure year-round. Vitamin D supports immune function, bone health, mood, and energy.* A blood test is the simplest way to know where they stand.
• "Which one should I choose?" Standalone D3 for foundational support or anyone on blood thinners. D3+K2 for comprehensive bone and cardiovascular wellness, especially for customers over 50. When in doubt, start the conversation with their goals.

Key Takeaways

Barlean's Vitamin D3 products solve the most common reason vitamin D supplementation underperforms: absorption that depends on meal timing. Emulsification delivers faster, more efficient absorption built right into the formula — no food, no timing coordination, no guesswork.*

Two products. One core advantage. Each designed for a specific customer.

• D3 Strawberry Milkshake: 5,000 IU of D3, emulsified for efficient absorption, strawberry milkshake flavor, foundational support for immune function, bone health, and mood, appropriate for blood thinner users, ages four and up.
• D3+K2 Pink Lemonade: 5,000 IU of D3 plus 90 mcg of MenaQ7 K2, emulsified, pink lemonade flavor, comprehensive bone health and cardiovascular wellness support, not appropriate for blood thinner users without healthcare provider guidance, ages four and up.

When customers find a supplement that fits their life and actually tastes good, they take it every day. When they take it every day, they get results. When they get results, they come back — and they bring their friends.
