Always check for allergies and speak with your physician or other healthcare professional before purchasing, taking or giving yourself or your child any medication or nutritional, herbal, or homeopathic supplement, or adopting any protocol for a health problem.

🌱

Lifestyle Factors

Give your child (and yourself!) the best foundation before vaccine day.

🥦 Before Vaccine Day

🥦
Eat your veggies!

Load up on whole, colorful foods in the days leading up to your vaccine.

🍭
Cut out refined sugar

Sugar suppresses immune function — reduce it in the week before your vaccine.

😴
Get at least 8 hours of sleep

Prioritize sleep the entire week before your vaccine.

🏃
Exercise regularly

Stay active, and at minimum exercise the day of the vaccine.

😌
Stay calm — be confident in your decision

Your nervous system state directly affects immune response.

🧘
Meditation

Insight Timer app or Headspace app.

🌬️
Breathwork

Oak app.

😄
Laugh, smile, be positive

Positive emotion is a genuine immune modulator.

🤝
Connect

Lean on your support system.

🙏 Practice Gratitude & Loving Kindness

😰 For Anticipatory Anxiety

💊
HKHK Liposomal Theanine+

100–200 mg 2× per day.

🌿
Homeopathic Argentum nitricum 30C

3 pellets 3× per day for anticipatory "what if" anxiety.

💊 HKHK V-Support Supplement Dosages

Start 0–4 weeks before your vaccine and continue 1–4 weeks after each dose. How early you start and how long you continue depends on your underlying health concerns, risk factors, and any vaccine reaction.

For teens and children: divide your child's weight (lbs) by 150 to get the approximate fraction of the adult dose. Example: a 75 lb child ÷ 150 = 0.5, so give approximately ½ the adult dose.

California Residents

Understanding the Prop 65 Notice on Our Label

You may see a Prop 65 notice on some HKHK products. Here's the full picture — including our actual test results.

ℹ️ For California Residents

Our Microbiome Magic™ Batch Tested Below Prop 65 Levels

✅

Microbiome Magic™ (Lot #511-0053): All four heavy metals independently tested and confirmed below Prop 65 thresholds.

Our Certificate of Analysis for the current production batch of Microbiome Magic™ (Lot #511-0053) confirms lead levels below the Prop 65 threshold of 0.5 mcg per serving. We commit to testing every batch and sharing results. Because ingredient sourcing varies by harvest, our label carries the warning as a precaution — results may differ batch to batch.

What is Proposition 65?

California's Prop 65 (1986) requires warning labels on products containing any of over 1,000 listed chemicals — even if naturally occurring and far below FDA/WHO safety guidelines. The California government itself states a Prop 65 warning "does not mean by itself that the product is unsafe." It is a right-to-know law, not a pure product safety law.

Why does lead appear in supplements and food?

Lead occurs naturally in soil and is absorbed by virtually everything grown in the ground — including the organic fruits, vegetables, and superfoods in our products. It cannot be fully eliminated from plant-based ingredients. Many everyday healthy foods contain naturally occurring lead at levels that exceed Prop 65 thresholds, yet food products are not required to carry this label. Only dietary supplements are.

Are HKHK products safe?

Yes — and we can prove it.

All our HKHK products are independently third-party tested for heavy metals, potency, and microbial safety on every single lot at our NSF-registered, GMP-certified manufacturing facility. Our current lot of Microbiome Magic™ (Lot #511-0053) was tested by ICP-MS — the gold-standard method — and here's what we found:

Test Result Standard
Lead 0.366 mcg/serving Prop 65 threshold: 0.5 mcg ✅ Passes
Arsenic <0.001 mcg/serving Prop 65 threshold: 10 mcg ✅ Passes
Cadmium 0.083 mcg/serving Prop 65 threshold: 5 mcg ✅ Passes
Mercury 0.024 mcg/serving Prop 65 threshold: 15 mcg ✅ Passes

Why does the label still carry a Prop 65 notice?

California's Prop 65 law requires a precautionary warning on supplements containing any detectable trace of certain naturally occurring substances — even when, as with Microbiome Magic™, independent testing confirms the product falls below the threshold. Because Microbiome Magic™ contains real whole-food ingredients grown in soil, trace amounts are naturally present. The Prop 65 safe harbor threshold of 0.5 mcg/day for lead is considered considerably lower than the amount of lead naturally occurring in normal daily serving sizes of fruits, vegetables, and herbs — and even at those low levels, we still pass.

Prop 65 guidelines are significantly more rigorous than many EPA and FDA guidelines for chemical exposure — for lead, the Prop 65 threshold is 0.5 mcg, whereas the FDA's current Interim Reference Level is 12.5 mcg/day for adults and 3 mcg/day for children.

I purchased outside California. Why does my product have this label?

Our products are sold nationwide. To ensure compliance with Prop 65 for all California residents regardless of where the product was purchased, we include the warning on all products.

Care Instructions

Caring for Your Supplements

📦

⚡ Open Immediately!

Some HKHK supplements contain heat-sensitive ingredients. Unpack your shipment as soon as it arrives and store all items according to each product label. Do not leave for an extended period of time in a hot car, mailbox, or porch in warm weather. All heat-sensitive items are shipped with a temperature-control pack and thermal packaging. In most cases, the temperature-control pack will melt and the items will be warm on receipt of your package. This is expected and is not a problem as short-term exposure to higher temperatures is not a cause for concern.

🌡️ Heat-Sensitive Items: Probiotics, liposomal liquids, and omega-3 oils should be stored in a cool, dry place or refrigerated after opening. Check each product label for specific guidance.
