CROWN WELLNESS


These are the questions David Black and the Crown Wellness team hear most often — from people who are new to the protocol, from existing customers refining their practice, and from practitioners exploring Crown Wellness for their patients. Every answer here is written to give you the full picture, not the simplified version. If your question is not answered here, David is available to answer it personally.
Who we are, where we came from, and why David still answers the phone.
David Black founded Crown Wellness in the early 1990s following the death of his father from melanoma. That personal loss prompted a question that has driven everything since: what more could have been done to support the body's own capacity to fight from within? That question led to decades of research, live blood sample analysis, product development, and direct customer guidance — and it is still the question that shapes everything Crown Wellness does.
David is not a medical doctor. He is an experienced natural supplement practitioner and the formulator of Crown Wellness's four proprietary products. He has examined tens of thousands of live blood samples over more than two decades, spoken personally with thousands of customers navigating their own wellness journeys, and built a protocol that reflects what that direct observation taught him. He still takes personal calls — not because it is a marketing strategy, but because he believes the people who use his products deserve direct access to the person who built them.
Crown Wellness has been distributing natural supplements since the early 1990s — over thirty years. It was founded in Florida and continues to operate from Miami Shores, Florida. All four proprietary formulas are manufactured in the USA.
Several things — but the most meaningful ones are these. First, the protocol architecture. Crown Wellness is not a collection of individual supplements sold separately. It is a coherent, protocol-based system designed by someone who has spent thirty years studying the relationship between blood health and overall wellness. Every proprietary product has a specific role within the system. Second, the personal access. David Black still takes personal calls.
If you want to talk to the founder before you buy — or at any point during your protocol — that option is genuinely available. This is not common in the supplement industry at any scale. Third, the approach to education. Crown Wellness does not simplify in order to sell. The educational resources on the site are free, thorough, and honest about what the products can and cannot do.
The blood vitality approach is the philosophical and practical framework that underpins everything Crown Wellness does. It is based on the observation — developed over thirty years of direct blood sample analysis — that the health of the body's internal cellular environment is deeply connected to how the body functions as a whole.
The approach focuses on supporting the body's own systems: the continuous regeneration of blood cells, the elimination of weak or compromised cells, the maintenance of gut integrity, and the supply of the trace minerals and natural inputs the body needs to maintain healthy blood at the cellular level.
Yes. David still takes personal calls and welcomes conversations with people who want to understand the program before committing to anything. You can usually find him directly by calling +1 (305) 720-3476. If not available, feel free to leave him a message so he can call you back!
How the protocol works, what to expect, and how to choose the right starting point.
The Optimal Blood Cleanse is David Black's complete blood vitality program — a combination of Crown Wellness's four proprietary formulas alongside carefully selected partner products, packaged into a 60-day or 120-day commitment. It includes CLO2, Diatomaceous Earth, Nano Silver, a premium probiotic, E3 Live Brain On, E3 Live Blue-Green Algae, and Systemic Formulas Fung DX.
It is the recommended starting point because the cleanse program works as a system. Each product has a specific role. Using them together, in the right combination and for the right duration, is how David designed the program to be experienced. Individual products are available and meaningful on their own — but the complete cleanse is where the full system operates.
The 60-day package is the recommended starting point for most first-time Crown Wellness customers. It provides the complete program in the quantities designed for a full 60-day commitment. The 120-day package is for those who are ready for a deeper, longer commitment from the outset. It provides larger quantities of each product and represents a greater value per unit than the 60-day package.
Many customers who complete the 60-day cleanse choose to continue immediately with the 120-day package or the Maintenance Package. Both include the same products and the same downloadable program instructions.
David's consistent observation over thirty years is that most people who stay with the program begin to notice meaningful changes in how they feel — energy levels, mental clarity, digestive function, overall physical baseline — within approximately 30 days. The experience deepens and becomes more consistent over the full 60 to 120-day program.
It is important to understand that the blood vitality cleanse works on the body's own timeline. The body regenerates blood cells continuously, but meaningful change in the overall blood environment is a cumulative process — not an event. Consistency matters more than any individual factor.
The program instructions — downloadable with each package — include dietary guidance that David recommends following during the cleanse. In general, the program works best alongside a whole-foods diet that minimizes processed foods, sugar, and alcohol.
These are not rigid requirements but practical recommendations — the program supports the body's natural processes, and those processes benefit from not being counteracted by inflammatory dietary inputs. For specific dietary questions related to your individual situation, David is available to discuss them personally.
Crown Wellness recommends consulting your healthcare practitioner before beginning any new supplement program, especially if you are taking prescription medications. Some specific interactions to be aware of: CLO2 should not be taken simultaneously with vitamin C or antioxidant supplements — separate them by at least two hours. Nano Silver may affect the absorption of certain antibiotics and thyroid medications.
Crystalloid Electrolyte Trace Minerals contains iodine — relevant for those managing thyroid conditions. This information is educational and does not constitute medical advice. Always consult a qualified healthcare professional before combining supplements with prescription medications.
If you are pregnant or nursing, consult your physician before beginning any new supplement program. Crown Wellness does not recommend the full program for pregnant or breastfeeding women without prior consultation with a qualified healthcare professional.
The Maintenance Program is designed for customers who have completed a 60-day or 120-day Optimal Blood Cleanse and want to continue supporting their blood vitality practice on an ongoing basis. It contains the core Crown Wellness proprietary products in the quantities appropriate for continued daily use rather than an initial program commitment.
The cleanest and most direct answer is: start with The Optimal Blood Cleanse for 60 days and see how you feel.
Alternatively, call always David (his number is in the footer of this page). He walks every new customer through the program in exactly this way — understanding where you are starting from, what you are hoping to support, and what the most sensible first step looks like for your specific situation.
Questions about CLO2, DE, Nano Silver, and Crystalloid Electrolyte.
No. This is the defining characteristic of the Crown Wellness CLO2 formulation. Most CLO2 products on the market require mixing two separate solutions together immediately before use — which produces an unpleasant smell, a sharp chemical taste, and a preparation step that many users find difficult to manage consistently.
Crown Wellness CLO2 is a 7% sodium chlorite formulation in a proprietary blend, designed so that the body's own hydrochloric acid — HCL — which the stomach produces naturally as part of normal digestive function, serves as the activator. The result is a formula that is colorless, odorless, and tasteless, requires no preparation, and is activated inside the body where the HCL is naturally present.
CLO2 should be taken in water only — not protein shakes, juices, or other beverages. CLO2 is an oxidizer and requires a clean water medium to activate properly via the stomach's HCL. Vitamin C, antioxidants, and other compounds present in juices and shakes can interact with CLO2 and reduce its effectiveness. Use water only, and separate CLO2 by at least two hours from vitamin C supplements or antioxidant-rich foods.
No. Crown Wellness CLO2 does not require refrigeration. Store in a cool, dry place away from direct sunlight, tightly sealed between uses. Room temperature storage is fine including for travel.
For a single day's use, a plastic container is acceptable. For ongoing storage and daily use, a glass container is strongly preferred. Glass preserves the integrity of the formula more reliably over time.
Mild nausea at the beginning of a CLO2 program is occasionally reported and is generally understood as part of the body's adjustment process. If you experience nausea, reduce your drop count by several drops and hold at that level for a few days until the sensation subsides. Then increase gradually — one additional drop per day — until you return to your target dosage. If nausea persists or is severe, discontinue use and consult your healthcare practitioner.
David's recommendation is to restart at approximately ten drops and build back up to your previous dosage over several days rather than jumping immediately back to where you were. A brief interruption resets the body's adjustment to some degree — starting back at a lower dose and building up avoids unnecessary discomfort.
Yes, with modification. For topical use, CLO2 should be activated externally with a small amount of fresh lemon juice or citric acid in a 1:1 solution before application. The pre-activated formulation that Crown Wellness sells is designed for oral dietary supplement use — the external activation step is required for topical applications.
Yes. Add an acid activator such as citric acid, lemon juice, or vinegar to the CLO2 before adding it to water for purification purposes. The Crown Wellness formulation without an external activator is designed for oral dietary supplement use — water purification requires external activation.
This distinction is important for safety.
Filter-grade DE contains approximately 60% crystalline silica and is used in pool filters and industrial applications. It is not safe for human consumption.
Food-grade DE contains less than 2% crystalline silica, which is the form of silica associated with health risks.
Crown Wellness DE is 100% food-grade and composed primarily of amorphous silica (approximately 84%), the naturally occurring, non-toxic form that is safe for human and animal consumption.
Always confirm that any DE product you purchase is clearly labeled as 100% food grade before consuming it.
Yes. Crown Wellness DE is food grade and safe for pets. It can be added to pet food or water. The Crown Wellness Pet Section below will help you understand better everything around the Crown Wellness approach to pets.
In 1999, the FDA ruled that colloidal silver products marketed as over-the-counter drug products for treating or preventing disease conditions are not generally recognized as safe and effective for those purposes. The same ruling explicitly stated that a silver product could be marketed as a dietary supplement under DSHEA if it meets those requirements and does not make disease claims.
Crown Wellness Nano Silver is positioned and labeled exclusively as a homeopathic dietary supplement. It does not claim to diagnose, treat, cure, or prevent any disease. It is formulated at 15 PPM, 99.999% purity, 5-nanometer particle size — a precision dietary supplement, not an OTC drug product. Crown Wellness shares this regulatory context proactively because informed customers make better decisions.
Trace minerals are water-soluble. The body uses what it needs and eliminates the remainder relatively quickly rather than storing them. Taking the formula three times daily — morning, midday, and evening — maintains a consistent mineral presence throughout the day, supporting the body's ongoing enzymatic and metabolic processes rather than providing a single large dose. This three-times-daily approach reflects the precision of a homeopathic formulation philosophy.

Many of our clients choose to extend the same foundational approach they use for themselves to their pets.
Below are the most common questions about how Crown Wellness products can be used safely and effectively for animals.
Yes. The same foundational formulas used by humans can also be used for pets.
The key difference is dosage, which should be adjusted based on the animal’s size and weight.
Most commonly, clients use Crown Wellness products with dogs and cats, but the same principles may apply to other animals.
If your pet is part of your family, the same foundational support approach can be considered.
Clients often choose to use Crown Wellness products for pets when they are looking to support:
• Overall vitality and energy
• Skin and coat health
• Digestive balance
• Immune system support
• General aging support
The goal is always the same: support the body’s natural ability to rebalance itself.
Most clients simply:
- Open the capsules
- Mix the contents into food or treats
This makes it easy to incorporate into your pet’s daily routine without stress.
Dosage depends on your pet’s size, weight, and condition.
A general rule is to start small and adjust gradually.
If you’re unsure, you can always reach out for guidance to find a starting point that makes sense for your pet.
Just like with humans, consistency is key.
Some pet owners report noticeable changes in a few weeks, while deeper changes may take longer depending on the situation.
The important part is staying consistent with the program.
No. Crown Wellness products are not intended to replace professional veterinary care.
They are used by many clients as a complementary approach to support overall wellness and balance.
