Hydrolyzed soy protein: Fast-Absorbing Vegan Protein, Evidence-Based Benefits, Dosage, and Side Effects
Hydrolyzed soy protein (HSP) is a plant-based protein that has been partially broken down into shorter peptides for faster digestion and easier mixing. It delivers all nine essential amino acids, is naturally lactose-free, and is widely used by athletes, active adults, and people who prefer vegan or dairy-free options. Compared with intact soy protein, hydrolysis can speed gastric emptying...
Hydrolyzed whey protein: Muscle Growth Benefits, Best Timing, Dosage by Body Weight, and Side Effects
Hydrolyzed whey protein is whey that has been partially “pre-digested” into smaller peptides. That processing shortens digestion time and can raise the speed at which amino acids—especially leucine—reach your bloodstream. Many people choose hydrolyzed whey to support muscle recovery after training, to get more predictable tolerance (for some, less bloating), or to meet higher daily protein needs when appetite...
Hydromorphone: Uses, Benefits, Recommended Dosage, and Safety Guidelines
Hydromorphone is a potent prescription opioid analgesic used when pain is severe and other treatments are insufficient. It acts primarily on mu-opioid receptors to blunt pain signals and reduce distress, with rapid onset in immediate-release forms and sustained control in extended-release tablets for opioid-tolerant patients. Because it is stronger milligram-for-milligram than morphine, hydromorphone can help when lower-potency opioids fail,...
Hydroval: Best Practices for Eczema Relief, Dosage by FTU, Treatment Length, and Safety Tips
Hydroval is a prescription-strength topical corticosteroid containing hydrocortisone valerate 0.2% (2 mg/g). It is designed to calm skin inflammation, ease itching, and shorten flares in common conditions such as eczema, contact dermatitis, psoriasis plaques on the body, and certain insect bite reactions. As a “medium-potency” steroid, Hydroval sits between over-the-counter hydrocortisone 1% and very strong prescription steroids. That balance...
Hydroxomethylbutyrate: Muscle Health Benefits, How It Works, Optimal Dosage, and Safety
Hydroxomethylbutyrate—better known as β-hydroxy-β-methylbutyrate (HMB)—is a leucine-derived compound used to support muscle health, particularly when training stress, aging, illness, or immobilization threaten lean mass. As a supplement, it is valued for two complementary actions: helping stimulate new muscle protein building and slowing protein breakdown. People use HMB to enhance strength gains, recover faster between sessions, maintain muscle during weight...
Hydroxyapatite: Benefits for Teeth and Bone, How It Works, Dosage and Daily Use, and Safety
Hydroxyapatite (HAp) is the calcium phosphate mineral that makes up most of your tooth enamel and a large share of bone. Because it is “bioidentical” to the mineral in your mouth, dentists use hydroxyapatite in two main ways: as a toothpaste and gel ingredient that helps remineralize enamel and soothe sensitivity, and as a biomaterial in professional bone and...
Hydroxybutyrate: Uses, Pros and Cons, Evidence-Based Dosages, and Side Effects
Hydroxybutyrate—more precisely, beta-hydroxybutyrate (BHB)—is a ketone body your liver makes during fasting, carbohydrate restriction, prolonged exercise, or a clinically supervised ketogenic diet. In recent years, BHB has also become available as a supplement (often called “exogenous ketones”) in forms like ketone salts, ketone esters, and (R)-1,3-butanediol. Interest has grown because BHB can serve as an efficient energy source for...
Hydroxychloroquine: Uses for Lupus and Rheumatoid Arthritis, Proper Dosing, Risks, and Monitoring
Hydroxychloroquine (HCQ) is a time-tested medicine originally developed as an antimalarial drug and later adopted as a core therapy in autoimmune conditions such as systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). It modulates the immune response rather than suppressing it outright, which helps control flares while maintaining a favorable long-term safety profile for most patients. In travel medicine,...
Hydroxycobalamin: Mechanism, Proven Uses, Dosage for Deficiency, and Safety Precautions
Hydroxycobalamin is a biologically active form of vitamin B12 used worldwide to treat B12 deficiency and, at higher doses, as a first-line antidote for cyanide poisoning. Compared with other B12 forms, it binds strongly to transport proteins, stays longer in the body, and is typically given by intramuscular (IM) injection. For deficiency, hydroxycobalamin helps restore red blood cell production,...
Hydroxycut: Science-Backed Benefits, How to Use, Optimal Dosage, and Safety
Hydroxycut is a long-standing brand of weight-management supplements. Across its product line, you’ll find combinations of caffeine and plant extracts—most notably robusta coffee (green coffee) standardized for chlorogenic acids—plus supporting ingredients such as B vitamins. People reach for Hydroxycut to add structure, energy, and a small edge to a calorie-reduced plan. The promise is modest, incremental support: a bit...
Hydroxypropyl cellulose: Benefits for Dry Eye Lubrication, Best Uses in Pharma and Food, Dosage, and Risks
Hydroxypropyl cellulose (HPC) is a versatile cellulose derivative used across medicines, eye care, foods, and cosmetics. In pharmacy, it serves as a binder, film former, thickener, and controlled-release polymer. In eye care, a sterile 5 mg HPC insert can steadily lubricate the ocular surface for patients with moderate to severe dry eye. As a food additive (E463), HPC stabilizes...
Hydroxytryptophan: Sleep and Mood Support, How It Works, How to Use, and Side Effects
Hydroxytryptophan—most often sold as 5-HTP or L-5-hydroxytryptophan—is a naturally occurring amino acid that your body converts into serotonin and, later, melatonin. Because serotonin influences mood, sleep, appetite, and pain perception, 5-HTP has become a popular supplement for people seeking steadier mood, better sleep quality, fewer nighttime awakenings, and calmer cravings. Research also explores its role in migraine prevention, fibromyalgia...
Hydroxytyrosol cardiovascular support explained, evidence-based benefits, dosing, and side effects
Hydroxytyrosol is a small, potent phenolic found in olives and extra-virgin olive oil. It is one reason the Mediterranean dietary pattern shows cardiovascular advantages. In controlled studies, hydroxytyrosol helps protect blood lipids from oxidative stress, improves markers of vascular function, and modestly supports cardiometabolic health when paired with diet and lifestyle. It is also well absorbed and rapidly conjugated...
Hygrophila spinosa kidney stone support, diuretic properties, dosage, and risks
Hygrophila spinosa—also cataloged as Hygrophila auriculata or Hygrophila schulli and known in Ayurveda as Kokilaksha or Talmakhana—is a marsh-loving herb used in South Asia for urinary health, fluid balance, and men’s reproductive wellness. Traditional texts describe its seeds and aerial parts as cooling, diuretic, and restorative. Modern laboratory work has examined antioxidant, anti-inflammatory, and kidney-protective actions, including models of...
Hypaque Meglumine: Indications, Preparation and Dilution, Adult and Pediatric Dosage, and Adverse Effects
Hypaque Meglumine is a long-standing iodinated contrast agent used to make blood vessels, organs, and hollow structures visible on X-ray and CT imaging. Its active component, diatrizoate meglumine, is a high-osmolality, water-soluble, ionic medium that delivers dense iodine to boost contrast. Clinicians still employ Hypaque formulations (including Hypaque-76 and Hypaque-Cysto) in selected vascular, CT, and retrograde urinary studies when...
Hypaque-Cysto: Indications for Cystography, Preparation and Dilution, Dosage by Volume, and Safety
Hypaque-Cysto is a radiopaque contrast agent formulated specifically for retrograde cystourethrography—the fluoroscopic study that outlines the urinary bladder, bladder neck, urethra, and (when reflux is present) the distal ureters. The agent is diatrizoate meglumine, an ionic, water-soluble, tri-iodinated benzoate salt supplied as a sterile solution that can be used as-is or diluted to lower concentrations. Because it stays within...
