WHY NOT NATURAL
SELLER SELLER SCORE AMAZON FULFILLED PRIME FREE SHIPPING
Why Not Natural 9.87

Features

FLUSH IMPURITIES WITH D-MANNOSE: A naturally occurring carbohydrate found in small quantities in fruits and vegetables. It binds with harmful bugs in the urine so they can't attach to the bladder wall.

CRANBERRY EXTRACT WITH 25% PROANTHOCYANIDINS (PAC): the powerful antioxidant PAC have been shown to interfere with E. coli's and h. pylori's ability to stick to the bladder and gut walls, so they are cleansed right out!

STRENGTHEN THE BLADDER WALL with vitamin D3:. Around half of people are low in this, which can contribute to recurring UTIs.

STOP BEFORE IT STARTS with Potassium Ascorbate: A buffered (or non-acidic) form of vitamin C that limits the growth of impurities. It's also an antioxidant and supports the immune system.

THE EXACT PROBIOTICS YOU NEED: Lactobacillus rhamnosus and Lactobacillus reuteri. Promote good vaginal health. These two specific probiotics have been shown to be the most helpful in fighting UTIs, vaginosis, and yeast overgrowth.

CLEANEST FORMULA ON THE MARKET: our formula contains only the above, plus spirulina, organic bamboo silica (great for hair, skin, and nails), and organic rice extract blend (rich in magnesium, a common deficiency). And that's ALL! No dairy, egg, fish, peanuts, soy, gluten, or preservatives.

THIRD-PARTY TESTED AND GUARANTEED: We produce in a cGMP certified facility to ensure purity and potency. We guarantee what's on the label and we guarantee you'll love it, or your money back!

WHY NOT NATURAL
COLLAGEN1
SELLER SELLER SCORE AMAZON FULFILLED PRIME FREE SHIPPING
Why Not Natural 9.87

Features

SKIN SUPPORT: a meta-analysis of 19 studies showed hydrolyzed collagen noticeably improved skin hydration, had a 35% reduction in wrinkles, and a 40% increase in skin elasticity when consumed for 90 days. It supports repair of skin collagen and elastin fibers, which weaken as we age.

NAILS AND HAIR: collagen improves strength and hydration of dry, brittle nails, and biotin supplementation has been shown to improve nail and hair growth.

SUPERIOR ABSORPTION: marine collagen is absorbed more efficiently than other sources of collagen due to the smaller particle size. Marine collagen is especially rich in glycine and proline, which have been shown to help skin retain moisture and contribute to a supple look and feel.

JOINTS: collagen supplementation has been shown to reduce joint pain by 43% and increase joint mobiity by 39%.

WHY NOT NATURAL QUALITY: no preservatives (like potassium sorbate), no sugar, and no common allergens (besides fish). Our marine collagen is a natural byproduct of the fishing industry and is 100% wild-caught - a sustainble alternative to pork and beef-derived collagen.

COMBINED BENEFITS: Together, the B complex improves hair, skin, and nails, stress and mood, neurological function, metabolism, and fatigue.

Scroll down to our infographic for more!

STRESS AND ENERGY BLEND: We also included the "honorary B vitamins" choline and inositol which are recommended to be taken with B complex to support fertility, serotonin, and body fat management. Also includes citrus bioflavonoids for metabolism and oxidative stress, trimethylglycine (TMG or betaine anhydrous) for athletic performance, hesperidin and quercetin for inflammation and cardiovascular health, and l-carnosine for brain and heart health. So many benefits!

EASILY ABSORBED, VEGAN, & ALL NATURAL: We use only bioavailable forms and by putting these in a liquid format, your body easily absorbs them so you feel great all day long. B vitamins are water-soluble which means you need to consume them every day, and we make it easy to do so! Plus no sugar, preservatives, corn syrup, or dyes.
