I started taking these about 3 weeks ago to try and help with acne. I’ve always had “struggled” with acne but about 6 months ago I started getting 3-6 cysts at a time around my mouth and neck area. I was popping approx 6-8 zits a day. My acne had gotten to the point to where not only was it affecting me mentally it was affecting my every day life physically. It would hurt to talk, smile, move my head, wear a scarf, put a blanket up up to my neck etc. Well I’ve been taking these for barely over 3 weeks now and my acne has calmed down. I’ve only had 1 cyst in 3 weeks. I’ve had little breakouts but NOTHING like what I was dealing with before. It’s also only been 3 weeks. When I wash my face at night there’s not 4-8 flared up zits. My skin looks calm after washing now and I just really have like “post acne inflammation” where I have some leftover red spots from previous zits but they have calmed down significantly. They also cover fairly well with makeup. My skin also looks smooth and feels smooth rather than me being able to feel bumps. The zinc was recommended to me to take by my aesthetician that I’m working with since March but I put off taking it because I hate taking pills. Now I wish I would’ve just started taking the second it was offered to me. My acne was affecting me so much that I was on my way to take accutane. I had the appointment set with my dermatologist and already had the pregnancy test done and had my primary care sign off on me to take it. My next step was to do my follow up with dermatologist and get my blood work done to get the prescription. My skin had improved so much within these 3 weeks that I canceled my accutane appointment. Knock on wood but I finally see a light at the end of the tunnel. At this moment, I’m no longer in pain. I can smile, sleep with my face touching the bed, etc etc with no pain. I am hoping to provide an update in about 1-2 months. For reference I’m 5’4” approx 140lbs. I started taking 1 tablet every day for a week. Then I started taking 1 in the morning and at night and this is what I will continue to do until everything calms down. Then I’ll return to taking once a day and then probably every other day etc. I also started taking fish oil approx 2 months ago and a probiotic approx 4 weeks ago. I’ve taken the zinc on empty stomach and have never experienced any side effects from it. I will say, the tablets do kind of smell. I try to hold my breath when taking it because they taste bad lol (but it’s not overwhelmingly bad by any means) ## Features - Source Naturals OptiZinc is zinc monomethionine, a patented combination of zinc and the essential amino acid methionine.

Why do you they add copper?** A: Zinc and copper are antagonists in the body. If one is high it depletes the other. This zinc has the zinc and copper in an ideal ratio to not cause any imbalance from one metal becoming to high. In your sons case, I would opt for zinc without copper added. I recommend zinc picolinate. **Q: Some of us take PRESERVISION ,which contains 34.8 zinc oxide, for MACULAR DEGENERATION.What is the difference between ZINC OXIDE and ZINC METHIONINE?** A: My favorite form of zinc supplementation is zinc gluconate because it is always (very reliably) much lower in cadmium, an extremely toxic heavy metal, than all other forms of zinc supplementaion. Also, zinc gluconate is very inexpensive compared to zinc monomethionine, which can be absorbed by the human body somewhat better. However, if your medical doctor (opthalmologist) prescribed Preservision, then I would stay with it to prevent losing his approval of your actions. Swallowing any of the 10 different forms of zinc supplementation would supply the very beneficial antioxidant mineral, zinc, which has been shown in scientific studies to help in preventing and treating diarrhea. The other 2 very beneficial antioxidant minerals are selenium and iodine. Although it is not an antoxidant, magnesium is the most beneficial mineral in human nutrition because it has been shown in scientific studies to strongly prevent sudden cardiac deaths (heart attacks). In addition to whole grains, almonds, and wild ocean fish, the best food sources of magnesium include all green vegetables. The green color in plants is caused by the pigment, chlorophyll. Each chlorophyll molecule contains exactly one magnesium atom. Think of magnesium whenever you see the green color in plants.As for macular degeneration, I would completely stop eating beef, lamb, pork, turkey, chicken, eggs, high-fat dairy, fast foods, fried foods, salty chips, cakes, and pastries. I would swallow at least 6mg of lutein softgels every day the rest of my life. I would swallow 3mg to 5mg of astaxanthin softgels every day. I would swallow 4,000mg of triphala tablets or capsules every day. I would swallow at least 120mg of benfotiamine capsules every day. I would swallow exactly 2,000 IU of vitamin D softgels every day. Do not swallow more than 2,000 IU of vitamin D every day because it would negate the entire benefit of swallowing vitamin D. I would swallow at least 500mg of vitamin B3/niacin (as nicotinic acid) tablets every day. Swallowing niacinamide, flush-free niacin, or time-release niacin would not have any health benefit. I would swallow Double Strength Fish Oil softgels every day. I would swallow exactly one 1,200mg conjugated linoleic acid softgel every day. I would chew several multi-probiotic capsules in my mouth every day. I would chew (or swallow) 1,000mcg of vitamin B12 (as methylcobalamin) tablets every day. I would eat foods made from soybeans such as natto (healthiest), tofu, edamame, unsweetened soymilk, soy sprouts, soy yogurt, soy meat, etc. I would eat cabbage family (cruciferous) vegetables raw. I would eat lily family (allium) vegetables raw. I would eat tomato paste and raw tomatoes. I would eat shiitake mushrooms (healthiest) and white button mushrooms. I would swallow reishi mushroom capsules every day. I would swallow astragalus capsules every day. I would eat the seaweed called, nori (laver). I would keep extra virgin olive oil in my home and immediately throw away all other vegetable oils. I would drink olive leaf tea, white tea (and/or green tea), and South African rooibos tea (and/or South African honeybush tea). I would eat fat-free yogurt. I would eat wild ocean fish, cooked by boiling in water without adding any salt. I would wear high quality sunglasses. I would pray to God for a miracle. Good luck. **Q: Is it necessary to take more extra copper with this product? Or does it contain the sufficient thing? I ask for persons who have enough time using it?** A: I'm sorry, I am not sure about that. I do take another multi-vitamin that has copper but not enough zinc for my liking. **Q: Zinc monomethionine is 21 percent elemental zinc by weight. Does this have 143 grams of Zinc monomethionine and 30 grams of elemental zinc?** A: The 30mg listed on the label currently represents the total amount of the compound as zinc methionine sulfate encompassed in each 1 tablet serving. Additionally, according to our raw material supplier files, approximately 20% of the compound is elemental zinc, which is approximately 6mg of elemental zinc per tablet. ## Customer Reviews ### ⭐⭐⭐⭐⭐ High-quality Zinc complex for better absorption *by C***. on April 12, 2026* Not all zinc supplements are created equal, and OptiZinc uses a patented zinc-methionine complex that is much easier for the body to absorb.

Both ascorbic acid (vitamin C) and methionine (monomethionine) help the human body get rid of cadmium, which on average is 20 times more plentiful in one multi-mineral tablet than one zinc tablet. [I suspect that dolomite (calcium magnesium carbonate), which is in your kid's rock collection and was once used in most multi-mineral and multi-vitamin pills, is very high in cadmium. Calcium carbonate appears to be OK with respect to cadmium. Japanese natto, which is very high in vitamin K2/MK-7, vitamin K2/MK-8, nattokinase, soy isoflavones, soy saponins, vitamin PQQ, and vitamin C, is also low in cadmium and very high in every mineral listed on your multi-mineral supplement. Wheat germ and shiitake mushrooms are both low in calcium but very rich in all other beneficial minerals]. The food in the typical daily American diet contains about 15 times the amount of cadmium contained in the average zinc tablet. Smokers inhale large amounts of cadmium. Also, chocolate, seaweed, and sea salt are high in cadmium. If taken within 24 hours of the onset of symptoms, zinc reduces the duration and severity of the common cold. Zinc is found in high concentrations in the retina and the amount declines with age so zinc supplementation may help reduce the risk of age-related macular degeneration. Zinc also helps heal acne and cold sores, improves overall immunity, and is used to treat people with an impaired ability to taste. Some people believe that together with selenium and vitamin C, zinc might help the human body to slightly more rapidly detoxify itself of mercury, lead, arsenic, and other unwanted metals. Other people believe that men, but not women, drain themselves of zinc regularly and need to replenish their supply. It's difficult to get even half of the Recommended Daily Value of zinc from eating all foods that are considered moderately high in zinc. However, oysters are an extremely, extremely rich source of zinc, containing much, much more zinc than one OptiZinc tablet. No other food contains anywhere near as much zinc as one OptiZinc tablet. Because they never have sand inclusions, small oysters are worth much more per pound (but not priced any higher) than large oysters, which frequently have sand inclusions. Swallowing more than one OptiZinc tablet per day could cause a severe copper deficiency. OptiZinc tablets were made to be swallowed, not chewed. If you accidentally chew an OptiZinc tablet, you will very likely experience an unpleasant, metallic taste in your mouth which won't go away for several hours. People who swallow zinc tablets to minimize the damage from viruses (common cold, influenza, pneumonia, HIV, HPV, herpes, shingles, hepatitis, meningitis, Epstein-Barr, dengue fever, malaria, etc.) and/or bacteria (gum disease, diarrhea, wounds, etc.) can greatly improve their results by also swallowing at least 2,000 IU of vitamin D3 daily, by drinking olive leaf tea, and by eating shiitake mushrooms. Some people also use fucoidan capsules, Korean red ginseng capsules, and/or benfotiamine capsules to improve their immune defenses. ## Frequently Bought Together - Source Naturals OptiZinc Zinc Methionine Sulfate Complex & Dietary Supplement* - 120 Tablets - Nordic Naturals Ultimate Omega, Lemon Flavor - 90 Soft Gels - 1280 mg Omega-3 - High-Potency Omega-3 Fish Oil Supplement with EPA & DHA - Promotes Brain & Heart Health - Non-GMO - 45 Servings - Doctors BEST High Absorption Magnesium Lysinate Glycinate 100% Chelated, Muscle Relaxation & Sleep Support, Non-GMO, Gluten Free, Soy Free, Vegan, 100% Chelated 240 Tablets --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/4351432-source-naturals-optizinc-zinc-methionine-sulfate-complex-120-tablets-important](https://www.desertcart.us/products/4351432-source-naturals-optizinc-zinc-methionine-sulfate-complex-120-tablets-important) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-23*
