Rho Nutrition Stack for Immune Support

A simple daily routine built to support normal immune function, with targeted additions for the times you want extra support. The Rho Nutrition Stack for Immune Support has two parts. The daily foundation includes vitamin C, vitamin D3 with K2, and quercetin. Glutathione and curcumin with resveratrol can be added during seasonal changes, travel, or busy stretches. Every product uses liposomal delivery, a formulation designed to support absorption.*

Key Takeaways

• The stack is built on three daily products: Rho Liposomal Vitamin C, Liposomal D3K2, and Liposomal Quercetin.

• Rho Liposomal Glutathione and Liposomal Curcumin + Resveratrol can be added when you want extra support.

• All five products can be mixed into one drink.

The Rho Immune Support Stack

The three core products each cover a different part of normal immune function. Vitamin C supports the work of immune cells, vitamin D supports normal immune function, and quercetin supports a healthy histamine response. They are designed to be taken together every day.

Daily use matters for this stack. Vitamin C dissolves in water and the body does not store much of it, so it needs a steady supply. Vitamin D and quercetin also fit best into a consistent routine rather than occasional use.

Every product in the stack uses liposomal delivery. A liposome is a tiny sphere made of phospholipids, the same type of fat that forms the outer layer of every cell. The liposome surrounds the nutrient and is designed to protect it during digestion and support absorption.* This matters most for nutrients that dissolve poorly in water, which includes several in this stack.

Rho Liposomal Vitamin C

Vitamin C is an essential nutrient, which means the body cannot make it and has to get it from food or supplements. It supports normal immune function in several ways. It helps maintain the skin and other barrier tissues, and white blood cells collect high levels of vitamin C inside them, where it supports how they move and do their work (Carr & Maggini, 2017).

Food sources of vitamin C include citrus fruits, kiwi, strawberries, bell peppers, broccoli, and tomatoes. A supplement adds a consistent daily amount on top of what you eat. The body clears extra vitamin C through the kidneys, so steady daily intake matters more than an occasional large amount.

Vitamin C is also an antioxidant. Immune cells produce reactive molecules as part of their normal activity, and vitamin C helps protect the cells from that oxidative stress (Carr & Maggini, 2017).

Vitamin C is the foundation of the stack because it pairs with other products in it. It pairs with quercetin to support a healthy histamine response, and it works with glutathione as part of the body’s antioxidant network.

Rho Liposomal Vitamin C delivers vitamin C inside liposomes designed to support absorption.* The main difference between liposomal and regular vitamin C is how each form moves through digestion.

Rho Liposomal D3K2

Vitamin D supports normal immune function. Immune cells, including T cells, B cells, and the cells that present signals to them, carry vitamin D receptors. Many of these cells can also convert vitamin D into its active form, so vitamin D can act right where immune cells are working (Aranow, 2011).

The body makes vitamin D when skin is exposed to sunlight. Shorter days and more time indoors in fall and winter mean less sun exposure, which is one reason people pay closer attention to vitamin D in colder months. Few foods contain much vitamin D. Fatty fish, egg yolks, and fortified milk are the main sources. Vitamin D levels vary widely from person to person, and a healthcare provider can check yours with a simple blood test.

Vitamin D also helps the body absorb calcium, which is where vitamin K2 comes in. Vitamin K2 activates proteins, including osteocalcin, that help direct calcium into bone (Schwalfenberg, 2017). Pairing the two in one product supports the way they work together. Vitamin K2 is found mainly in fermented foods such as natto and in some cheeses, so many people get little of it from diet (Schwalfenberg, 2017).

Rho Liposomal D3K2 combines vitamin D3 with vitamin K2 in the MK-7 form in a berry-flavored liquid.* Vitamins D and K are both fat-soluble, so the phospholipid liposome gives them a fat-based carrier.

Rho Liposomal Quercetin

Quercetin is a plant compound called a flavonoid. It is found in onions, broccoli, apples, berries, grapes, and tea (Mlcek et al., 2016).

Quercetin supports a healthy histamine response. Histamine is a chemical released by immune cells called mast cells, and research suggests quercetin may help limit how much histamine those cells release. Quercetin also has antioxidant activity and supports normal immune function (Mlcek et al., 2016).

Quercetin pairs well with vitamin C. Both are antioxidants, and both support a healthy histamine response. Research associates adequate vitamin C status with lower histamine levels (Carr & Maggini, 2017), which gives the stack two nutrients that support the same response.

Quercetin dissolves poorly in water, which limits how much the body absorbs from food or standard capsules. A liposomal format gives it a fat-based carrier designed to support absorption.*

Rho Liposomal Quercetin is a tropical fruit-flavored liquid that supports a healthy histamine response and normal immune function.* It can be taken straight or mixed into cold water, juice, or a smoothie.

When you need extra support

Some times of year and some stretches of life put more demand on the body. Seasonal changes, travel, short sleep, and busy or stressful weeks are common times people want extra support. Two Rho products can be added to the daily stack during these periods, and both work alongside the vitamin C already in it.

Seasonal changes bring less sunlight, more time indoors, and shifts in sleep and routine. Travel can mean long days, time zone changes, and irregular meals. Busy or stressful weeks often come with shorter sleep and less time to eat well. The extra support products are meant for stretches like these, then can be scaled back when life settles down.

Rho Liposomal Glutathione

Glutathione is the body’s main antioxidant inside cells. The body makes it from three amino acids: glutamate, cysteine, and glycine. It helps protect cells from oxidative stress and supports the body’s natural detoxification pathways.

Glutathione and vitamin C work as a team. After vitamin C neutralizes a free radical, it becomes inactive. Glutathione helps return it to its active form so it can keep working (Pizzorno, 2014).

Glutathione levels tend to be lower in older adults. One study found that older adults made glutathione more slowly than younger adults, largely because they had less of the amino acids cysteine and glycine available (Sekhar et al., 2011).

Glutathione may also support normal immune cell function. In a one-month pilot study of 12 healthy adults, liposomal glutathione raised glutathione levels in the blood and increased natural killer cell activity, a marker of immune cell function (Sinha et al., 2018). The study was small, and larger trials are needed.

Rho Liposomal Glutathione delivers glutathione in liposomes made with phosphatidylcholine from non-GMO sunflower lecithin.* It has a mild sulfur taste from the cysteine in glutathione, and many people find it easiest to take cold.

Rho Liposomal Curcumin + Resveratrol

Curcumin is the main active compound in turmeric. It has been studied for its role in supporting a healthy inflammatory response and the body’s antioxidant defenses (Hewlings & Kalman, 2017). Resveratrol is a plant compound found in grapes, berries, and peanuts.

A healthy inflammatory response is part of how the immune system normally works. During more demanding periods, curcumin and resveratrol help support that response.*

Curcumin and resveratrol are both fat-soluble and dissolve poorly in water, which makes them hard to absorb on their own. Rho Liposomal Curcumin + Resveratrol delivers both inside liposomes designed to support absorption.* It rounds out the extra support pair: glutathione covers antioxidant defense inside cells, and curcumin with resveratrol supports a healthy inflammatory response.*

How to take the Rho Nutrition Stack for Immune Support

The core stack takes about a minute each morning. Add one serving each of Rho Liposomal Vitamin C, D3K2, and Quercetin to a glass of cold water or juice, stir, and drink it with breakfast. Taking it with a meal suits D3K2, since vitamins D and K are fat-soluble.

When you want extra support, add Rho Liposomal Glutathione and Curcumin + Resveratrol to the same drink, or take them together later in the day. Rho’s liquids are designed for taking several products together in one glass.

Follow each label for serving size and storage. Shake each bottle before use. Keeping the bottles together in the refrigerator makes the morning drink quicker to put together.

For travel, Rho Travel Packs come as single-serve liquid packets, so the stack can come along without bottles.

FAQs

Can you take all the products in the stack together?

Yes. All five products are liquids designed to be mixed into the same drink, and Rho products are formulated to be taken alone or together. If you have a health condition, check with your healthcare provider before starting a new supplement routine. The same applies if you are pregnant or nursing.

What is the best time of day to take the stack?

Morning with breakfast works well for most people. It is easy to remember, and taking D3K2 with a meal gives the fat-soluble vitamins food to travel with. Consistent supplement timing matters more than the exact hour, so pick a time you can stick with every day.

Can you take the stack year-round?

Yes. The three core products are designed for daily use throughout the year. Many people pay closer attention to vitamin D in fall and winter, when there is less sunlight, and keep the rest of the routine the same.

How long should you use the extra support products?

Use them for as long as the demanding period lasts, such as a few weeks of travel, a busy season at work, or a change of seasons. Some people take glutathione and curcumin with resveratrol every day as part of their regular routine. Many people start them a week or two before a trip or a busy stretch and continue until it ends. There is no set cycle, so follow the label and your healthcare provider’s guidance.
