"I have used HCL+2 for over a year now. I used to feel bloated and be constipated every day. I had no idea it was because I was low on stomach acid and digestive enzymes. After reading a few books and making the recommended modifications, my life has been changed forever!"

triple-action formula for better digestion

Low, not high, levels of stomach acid (HCl) are often an underlying cause of heartburn, acid reflux and GERD... HCL+2 helps optimize the body's HCl levels and restore comfortable digestion!

• BOOSTS STOMACH ACID – Replenishes critical HCl (hydrochloric acid) levels to support healthy digestion and relieve acid reflux at the root.

• BREAKS DOWN PROTEINS & FATS – Pepsin and Ox Bile supports the complete breakdown of protein and emulsification of fats, helping reduce heaviness, gas, and discomfort after meals.

• IMPROVES NUTRIENT ABSORPTION – Enhances your ability to absorb minerals like calcium, magnesium, and iron—especially important as you age.

Highlights

If you feel heavy, bloated, or experience indigestion after eating—especially meals rich in protein or fat—low stomach acid could be to blame. It affects your ability to digest food properly and absorb critical nutrients, leaving you feeling tired, inflamed, or undernourished.

HCL+2 supports your body's natural digestive function by replenishing hydrochloric acid and pairing it with pepsin and bile extract for added digestive strength. It's ideal for anyone with sluggish digestion, gallbladder issues, or symptoms of low stomach acid like burping, bad breath, reflux, or food sitting "like a rock."

How to Use

Adults take one to two (1-2) caplets three times daily, during or immediately following a meal, or as directed by a healthcare professional.

Note: Not recommended for use with anti-inflammatory medications, or for use by individuals with hiatal hernia, ulcers, pre-ulcerous conditions or esophageal irritation or erosion or a thinned stomach lining.

Better Digestion, Better Health

Supports Protein Breakdown
HCL+2 provides essential stomach acid and pepsin to help digest proteins efficiently, preventing bloating and discomfort after meals.

Improves Nutrient Absorption
Low stomach acid can lead to nutrient deficiencies—HCL+2 helps your body absorb critical vitamins and minerals for better overall health.

Reduces Gas & Bloating
By restoring stomach acid balance, HCL+2 supports smooth digestion, reducing indigestion and minimizing bloating.

Enhances Gut Health & Detoxification
Proper stomach acid levels create a healthy digestive environment, helping to detox and prevent harmful bacteria, yeast and pathogen overgrowth in the GI tract.

Total Digestive Support from Start to Finish

HCL+2 was designed to address what most supplements overlook: the critical need for proper stomach acid. Without enough HCl, your body simply can’t extract the nutrition from your food—no matter how clean you eat. This formula jumpstarts digestion where it all begins: in the stomach.

Each capsule contains the precise combination of Betaine HCl, Pepsin, and Ox Bile extract to ignite your digestive cascade, reduce common discomforts like bloating and reflux, and help your body absorb the nutrients it craves. Whether you’re 35 or 75, HCL+2 helps reset your digestion so you can feel energized, clear-headed, and truly nourished.

Questions? We've Got Answers!

Why is stomach acid important for digestion?

Stomach acid is essential for breaking down food, absorbing nutrients, and preventing harmful bacteria from overgrowing in the gut. Without enough stomach acid, digestion becomes sluggish, leading to bloating, indigestion, and nutrient deficiencies.

What’s the difference between Digesta-Key and HCL+2?

HCL+2 supports the very first stage of digestion by restoring stomach acid and aiding protein and fat breakdown—ideal if you feel heavy or bloated right after meals.

Digesta-Key, on the other hand, contains a full-spectrum enzyme blend that works later in the digestive process to break down carbs, proteins, and fats throughout the GI tract.
Many people take both for complete digestive support!

Can I take HCL+2 if I have acid reflux?

Low stomach acid is often mistaken for high stomach acid. If you experience reflux due to undigested food sitting in your stomach too long, HCL+2 may actually help by improving digestion. However, consult your doctor before use if you have a history of ulcers or severe reflux.

How do I take HCL+2 for best results?

Take one capsule with meals, especially those containing protein. If needed, you can gradually increase the dosage until you feel optimal digestion without discomfort.

What are the signs of HCl deficiency?

Prolonged emotional tension and poor dietary habits can lead to low levels of HCl. In addition to digestive concerns, these signs of HCl deficiency may also indicate the need for an HCL+2 supplement: bone loss, low iron levels, broken blood vessels on the cheek, and/or hair loss.

Our Customers Say It Best

"HCL+2 has stopped me from having to take over the counter anti-acids! I was taking them every single day to avoid heartburn/acid reflux. I have not taken them in months now since I implemented this product. I feel so much better. I take one capsule with every meal. Thank you for this wonderful product!!"
– Jennifer W.

"I used to bloat sometimes for no reason at all but not any longer! Ever since taking two of these with each meal, my bloating is gone! I also noticed that I no longer get heartburn after eating. I'll always use HCL+2 and I love that it comes from a trusted source!!"
– Tricia

"This was a game changer for me, my stomach would hurt after really eating anything. I knew my stomach acid was low but wasn’t sure how to fix it until I came across HCL+2. It’s a must with meals and I no longer have stomach/digestive issues! I take it along with Bile Builder. Thanks UNI KEY!"
– Shana L.

"Most people have been misled to believe that heartburn, bloating, and indigestion come from too much acid—when in fact, it's usually just the opposite. As we age or live under stress, stomach acid naturally declines, and this can wreak havoc on our entire digestive system. That's exactly why I created HCL+2: to address the real root cause of digestive discomfort and restore the essential acid your body needs to thrive.

This powerful formula combines what I call the 'Holy Trinity of Digestion'—Betaine HCL to reignite your stomach acid, Pepsin to support protein breakdown, and Ox Bile to emulsify and digest fats. These three ingredients work together in harmony to support every stage of digestion, from the moment food enters your stomach to its final breakdown and absorption.

When your stomach acid is strong and your enzymes are fully supported, everything else falls into place—fewer food sensitivities, less bloating, clearer skin, more energy, and even a stronger metabolism and immune system. HCL+2 is one of my daily non-negotiables for healthy aging, vibrant digestion, and truly transformative wellness from the inside out."

It really tipped the scales in my favor with cleaning up my digestion issues. No more heartburn!

I only took one so far. I find them hard to swallow
This is the first product I have had trouble with

Hi Betty,
We appreciate your feedback! If you find the HCL+2 tablets difficult to swallow, they can be broken into smaller pieces to make them easier to take. This will not affect the effectiveness of the product.
Yours in good health,
UNI KEY Staff
