Keeping our immune system healthy is one of the most crucial things we can do to avoid getting sick. Our immune system is compromised by many different parts of our lifestyle, including nutrition, stress, sleep, toxins and viral or bacterial illnesses. These factors can also compound on top of each other and make us more susceptible to sickness and feeling run down and tired. Staying in good health, eating well, and getting enough sleep is critical to a healthy immune system, but we can also provide our bodies with immune support with supplements. Futurebiotics immune support supplements have three key components to help boost your immunity, including Arabinogalactan, which has been shown to provide targeted immune support, MaitakeGold 404, which is a mushroom-based immune booster, and AloeBiotics, an all-natural immunomodulator*. Take two capsules a day with a meal, and for optimal results, take for two to eight weeks and then discontinue use for four weeks before using again.

●IMMUNE BOOSTING: Supports the body's natural defenses by enhancing the activity of immune system cells and can also act as a therapeutic agent in conditions associated with lower immune function●HIGHEST QUALITY INGREDIENTS: ImmunActiveTM contains clinically-studied polysaccharides, Arabinogalactan and Maitake Mushroom that help support healthy immune function●HIGHLY REGARDED AND RECOGNIZED: Our Products Have Been Consistently Recommended By The Foremost Nutritional Scientists●HEALTHIER LIFESTYLE:Futurebiotics has been committed to Creating a Healthier Future* by helping our customers lead healthier lives through better nutrition

N-Acetyl Cysteine from Source Naturals is a stable form of the sulfur amino acid L-cysteine. It's a powerful natural antioxidant amino acid that is a precursor to glutathione. Glutathione is activated by the selenium-containing glutathione peroxidase, one of the most important antioxidant enzymes in the body. N-acetyl cysteine may be more helpful than some other glutathione supplements, which may break down during digestion and lose potency.

Cinnamon has been used for thousands of years for preservation, as an aromatic, and as a health aid. More recently, extensive research has been done on its potential health benefits, but it can be hard to get enough to make an impact in the body in whole form, making cinnamon extracts an ideal option. Cinnamon is packed with antioxidants, particularly polyphenols, which help protect the body from free radicals that cause oxidative damage*. It's also been shown to have anti-inflammatory properties*. Inflammation can cause long-term, chronic problems if not addressed. Most impressively though, cinnamon has been studied for its ability to improve sensitivity to insulin and potentially lower blood sugar levels*. Futurebiotics cinnamon extract CinnaCARE is formulated with Cinnulin PF, GlucActive, and Bioperine. These ingredients are designed to further support healthy glucose levels and maximize absorption so you're getting the most out of our cinnamon supplements for diabetes*. Take one capsule twice daily, preferably one capsule 20 minutes before morning and evening meals.

●MAINTAIN GLUCOSE LEVELS: CinnaCare may assist with blood sugar control and decreases fasting glucose levels when taken consistently.●HIGH POTENCY CINNAMON EXTRACT: CinnaCare is a powerful antioxidant; it supports healthy blood sugar levels, promotes heart health, helps with weight management, helps with joint pain, and serves as a power anti-inflammatory supplement●HIGHLY REGARDED AND RECOGNIZED: Our Products Have Been Consistently Recommended By The Foremost Nutritional Scientists●HEALTHIER LIFESTYLE:Futurebiotics has been committed to Creating a Healthier Future* by helping our customers lead healthier lives through better nutrition
